DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 1
,
2
and
3
, the motor operated stored energy circuit breaker system
1
comprises a circuit breaker assembly
100
, which may for example be rated for 630 Amperes as shown, and a motor operated stored energy circuit breaker assembly
200
. Of course, the circuit breaker assembly
100
may also be rated for 125 Amperes or 250 Amperes, as shown in
FIG. 4
, or any other suitably appropriate current rating. The motor operated stored energy circuit breaker assembly
200
has a molded thermoplastic external housing
543
, although any other suitably appropriate material may be used.
As will be discussed in further detail later, the assembly operates as follows: as shown in
FIGS. 8 and 14
, for example, a manual reset/charging operator handle
537
is used to reset and charge charging springs
516
a
and
516
b
of the motor operated stored energy circuit breaker assembly
200
. Using the manual reset/charging operator handle
537
to reset the motor operated stored energy circuit breaker assembly
200
causes the circuit breaker assembly
100
to go to its OFF position and the charging springs
516
are charged. When the manual reset/charging operator handle
537
is repeatedly and ratchetedly rotated or turned about ninety (90) degrees counter-clockwise and then back to its initial starting position, it causes a one-way or uni-directional clutch
519
to slip so that a worm gear
507
(see
FIG. 16
) does not rotate or otherwise move. Also, the described initial counter-clockwise movement of operator handle
537
causes handle clutch
519
b
to slip so that operator handle shaft
513
does not move, while the return clockwise movement of operator handle
537
grabs or locks operator handle shaft
513
and causes pinion gear clutch
519
a
(see
FIG. 16
) to slip with respect to the operator handle shaft
513
so that the worm
517
and worm gear
507
do not move. A manual/automatic lockout slide handle
546
allows local control of the motor operated stored energy circuit breaker assembly
200
when its manual/automatic lockout slide
550
is in the unlocked manual position and also allows some local control when the manual/automatic switch
550
is in the automatic position. In particular, an operator can actuate the ON and OFF buttons
548
and
609
, respectively. The ON switch
548
is used to release the charged springs
516
a
and
516
b
so as to force a toggle handle
103
of the circuit breaker assembly
100
to its ON position. In particular, the ON switch
548
causes actuation of a latch bell crank
561
so as to rotate D-shaft latch
544
, which releases main operator gear
515
allowing it to rotate so as to cause the circuit breaker toggle handle
103
to move to its ON position.
The circuit breaker assembly
100
may comprise a circuit breaker subassembly and a circuit breaker plug-in unit (not shown). The circuit breaker subassembly comprises a toggle handle
103
, circuit breaker lug openings or apertures and circuit breaker mounting openings or apertures. Although not shown, threaded copper studs may be passed through circuit breaker mounting openings or apertures and are received by tulip contacts in the plug-in unit so as to connect or mount the circuit breaker unit to the circuit breaker plug-in unit. In this way, a current path may be provided through the plug-in unit to the circuit breaker assembly. Further, and although not shown, the circuit breaker subassembly may further include a push-to-trip button, a trip current rating adjustment or setting (Ir) and a magnetic current adjustment or setting (Im) for a mag-latch in the circuit breaker subassembly.
As shown in
FIGS. 1
to
4
, and as is detailed in
FIG. 5
, the motor operated stored energy circuit breaker may have the following operating features:
If the selector bar or automatic/manual switch
550
s
is set to its manual position and the circuit breaker assembly
100
is OFF, then the charging springs
516
a
and
516
b
of the motor operated stored energy circuit breaker assembly
200
may be charged, the contacts of the circuit breaker assembly
100
are open, remote ON switch
548
r
and remote OFF/TRIP switch
609
r
are blocked, the local OFF/TRIP switch
609
does not trip the circuit breaker assembly
100
(which stays in its reset or OFF position), status indicator light pipe
534
b
indicates OFF/CHARGED and the motor operated stored energy circuit breaker assembly
200
can be locked electrically using automatic/manual switch
550
s
and/or mechanically using cylinder lock
618
. In its locked position, the unit cannot be operated either locally or remotely. In its unlocked position, the unit may be operated by pressing ON switch
548
, which closes the circuit breaker assembly
100
in less than on the order of about 100 milliseconds.
If the selector bar or automatic/manual switch
550
s
is set to its manual position and the circuit breaker assembly
100
is ON, then the charging springs
516
a
and
516
b
of the motor operated stored energy circuit breaker assembly
200
are discharged, the contacts of the circuit breaker assembly
100
are in their closed position, the remote ON and OFF/TRIP switches
548
r
and
609
, respectively, are blocked, the motor operated stored energy circuit breaker assembly
200
cannot be locked and the status indicator light pipe
534
a
indicates ON/DISCHARGED. In this state, the circuit breaker assembly
100
may be turned OFF by pushing local OFF/TRIP switch
609
, which may optionally actuate a bell alarm (not shown), on the circuit breaker assembly
100
. If there is control power, the OFF/TRIP switch
609
trips the circuit breaker assembly
100
and causes it to go to its OFF position. If there is no control power, the circuit breaker assembly
100
will trip but the status indicator light pipe
534
a
indicates ON/Discharged. If the stored energy assembly is wired through the optional bell alarm (not shown), when control power is restored, the motor operated stored energy assembly
200
is reset causing the circuit breaker assembly
100
to return to its OFF position. The operator charging/reset handle
537
may also be used to turn OFF the circuit breaker assembly
100
without actuating its bell alarm. If there is control power, the motor operated stored energy assembly
200
is set to its charged condition so that the circuit breaker assembly
100
is in its OFF position after a few strokes of the operator charging/reset handle
537
. If there is no control power, then continued stroking or ratcheting of the operator charging/reset handle
537
sets the motor operated stored energy assembly
200
to its charged condition so that charging springs
516
are charged and causes the circuit breaker assembly
100
to go to its OFF position. At this point, the charging/reset handle
537
is disengaged.
Optionally, if the stored energy assembly is wired through the optional bell alarm, and if the bell alarm (not shown) of the circuit breaker assembly
100
is actuated after a short circuit trip or under-voltage trip, then the motor operated stored energy assembly
200
may go to its CHARGED/RESET position so that the circuit breaker assembly
100
is set to its OFF position. If the circuit breaker assembly
100
trips by shunt trip, under voltage release, overload or short circuit, the motor operated stored energy assembly
200
does not change its position and the status indicator light pipe
534
a
would indicate ON. Also, the bell alarm (not shown) could be wired so as to actuate the OFF/TRIP switch
609
and charge the springs
516
a
and
516
b
.
If the selector bar or automatic/manual switch
550
s
is set to its automatic position, then when the circuit breaker assembly
100
is in its OFF position, the springs
516
a
and
516
b
are charged, the circuit breaker assembly
100
is closed, remote operation is not blocked, the unit cannot be locked, the status indicator light pipe
534
a
indicates ON/DISCHARGED and the charging/reset handle
537
is engaged. Since there is no local OFF control when automatic operation is enabled, the motor operated stored energy circuit breaker assembly
100
may be only be turned OFF by pushing the remote OFF switch
609
r
of FIG.
6
. Alternatively, of course, local control through the remote OFF switch
609
r
could be made available to the user if that was desired. If there is control power, the local OFF switch
609
of
FIG. 6
may be used to trip the circuit breaker assembly
100
and cause the toggle handle
103
of the motor operated stored energy assembly
200
to go to its OFF position. If there is no control power and the stored energy assembly is wired into the optional bell alarm (not shown), then the motor operated stored energy assembly
200
only goes to its OFF (charged) position when control power is restored. If the remote OFF switch
609
r
is actuated, the motor operated stored energy assembly
200
goes to its OFF (charged) position in less than on the order of about one (1) to five (5) is seconds. Unless the motor operated stored energy circuit breaker assembly
200
is connected to a bell alarm of the circuit breaker assembly
100
, the motor operated stored energy assembly
200
remains in its ON (uncharged) position if the circuit breaker assembly
100
trips by shunt trip or short. Using the charging/reset handle
537
to turn OFF the circuit breaker assembly
100
does not trip it, but will cause the motor operated stored energy assembly
200
to go to its OFF/CHARGED position if there is control power. If there is no control power, then the reset/charging handle
537
must be used to fully recharge the motor operated stored energy assembly
200
, thereby completing the charge cycle and causing the status indicator light pipe
534
b
to indicate OFF.
In the manual position, holding the ON and OFF/TRIP switches
548
and
609
, respectively, essentially simultaneously or at about the same time, causes the motor operated stored energy circuit breaker assembly
200
to cycle OFF and ON. To lock the motor operated stored energy assembly
200
using pad locks or key locks, the selector bar or automatic/manual switch
550
s
must be in its MANUAL position so as to lock out both electrical and mechanical operations of the motor operated stored energy circuit breaker assembly
200
using hasp
538
and a locking apparatus, such as a wire and seal or a locking cable (not shown). In the automatic (remote) position, as can be seen from
FIG. 7
, nothing will happen since the motor operated stored energy assembly
200
is only OFF or ON but cannot be both OFF and ON at essentially the same time.
FIG. 6
is a schematic view of the circuitry
1000
of the motor operated stored energy circuit breaker assembly
200
with a control module
1200
, while
FIG. 7
is a schematic view of the circuitry of the control module
1200
. As regards the above and as is shown in
FIG. 7
, a cam operated limit switch
531
a
having circuit breaker open position
1235
and circuit breaker closed position
1234
which operates the electric motor
521
when the circuit breaker assembly
100
is open and interrupts operation, is controlled by the release solenoid
532
, that is controlled by the relative position of the operator gear cam
515
c
of FIG.
15
. The automatic/manual switch
550
s
controls the operation of switches
535
a
and
535
b
(switches S
2
A and S
2
B). As shown, the locking hasp
538
may be used to inhibit operation of the OFF Switch
548
and automatic/manual switch
550
s
. Optionally, automatic recharging of the charging springs
516
a
and
516
b
after the circuit breaker assembly
100
trips may also be provided.
More specifically,
FIGS. 6 and 7
show an electronic circuit
1200
for causing the electric motor
521
on a motor operated stored energy circuit breaker assembly
200
to start and continue to run when a short duration signal of at least on the order of about ten milliseconds is applied. As discussed, the motor operated stored energy circuit breaker assembly
200
may have relatively fast circuit breaker closing times (for example, less than on the order of about 100 milliseconds) and a relatively slow opening cycle (for example, less than on the order of about one (1) to five (5) seconds). Also as discussed, the closing cycle is powered by the charging springs
516
a
and
516
b
, which are charged during the opening cycle by operating the electric motor
521
. Because the motor running time is relatively long and the motor starting signal is relatively short, it is believed that it may be desirable or even necessary, depending on the application, to have some way of supplying the current to the electric motor
521
after the motor starting signal is momentarily applied by solenoid
532
. While this may be done using an additional cam and limit switch in an alternative embodiment, it is believed to be preferable to use the electronic control module
1200
as described herein.
It is believed that the electronic control module
1200
may provide the following advantages: the electric motor
521
continues to run even if only a relatively short duration motor starting signal is applied; an extra cam and limit switch are not needed; there may be improved reliability and reduced cost; either a universal AC or a DC motor may be used; there should be reduced space requirements in the motor operated stored energy circuit breaker assembly
200
; it should be more difficult and more unlikely for a user to connect the wrong polarity wire when connecting power to the motor operated stored energy circuit breaker assembly
200
.
FIGS. 6 and 7
illustrate the electronic circuit assembly
1200
in which either AC or DC power may be supplied between terminals
1210
a
and
1210
b
. The current may be of either positive or negative polarity. As designed, it is intended that the electronic control module
1200
essentially keep electric current flowing through the motor when a set of electrical contacts between points
609
r
or
609
are momentarily closed.
In particular, when the motor operated stored energy circuit breaker assembly
200
is in its uncharged state so that the circuit breaker assembly
100
is closed to its ON position, cam operated limit switch
531
is in its closed circuit breaker position and contacts terminal
1234
. The position shown in
FIG. 7
is the open circuit breaker position. In this way, cam operated limit switch
531
allows current flow through the electric motor
521
. If there is an AC voltage between terminals
1210
a
and
1210
b
, it is converted to a full wave rectified DC signal by a bridge rectifier
1220
formed by diodes
1221
,
1222
,
1223
and
1224
. When either local OFF switch
609
or remote OFF switch
609
r
is momentarily closed, depending on the position of mechanical automatic/manual switch
550
s
and corresponding electrical switches
1260
a
and
1260
b
, current flows through a gate
1272
of SCR
1271
thereby turning it on. Current continues to flow through SCR
1271
until the electric motor
521
causes the circuit breaker assembly
100
to move to its OFF or open position. At this time, cam operated limit switch
531
moves from a first position
1234
, corresponding to a closed circuit breaker position, to a second position
1235
, corresponding to an open circuit breaker position, in series with solenoid
532
thereby stopping current flow through SCR
1271
and the electric motor
521
. Capacitor
1251
is intended to prevent the voltage across the SCR
1271
from going to or significantly approaching zero so as to turn off the SCR
1271
. Capacitor
1251
is selected such that the control module circuit
1200
works throughout an appropriate specified range, such as about 24 to 250 volts AC or DC, for certain class circuit breakers assemblies. Of course, the appropriate and specified range may be different for other class circuit breakers. As designed, it is believed that the control module circuit
1200
should operate correctly regardless of whether the input voltage is AC or DC and regardless of the voltage polarity.
More specifically, as shown in
FIG. 7
, the bridge rectifier
1220
comprising diodes
1221
,
1222
,
1223
and
1224
is parallel to capacitor
1251
. The bridge rectifier
1220
and capacitor
1251
are electrically connected to electric motor
521
. A first sub-circuit comprising resistor
1261
, capacitors
1253
and
1254
, and zener diode
1225
provides the input signal to trigger the SCR gate
1272
. In particular, resistor
1261
is in series with the parallel combination of capacitors
1253
and
1254
and zener diode
1225
. The electric motor
521
is connected between points
1243
and
1244
. Points
1241
and
1243
are common nodes for bridge rectifier diodes
1221
and
1222
and capacitor
1251
. A second subcircuit comprises capacitor
1252
in parallel with SCR
1271
, which has capacitor
1254
tied between its SCR gate
1272
and relative ground point
1242
. Terminal
1210
a
connects between bridge rectifier diodes
1221
and
1223
, while terminal
1210
b
connects between bridge rectifier diodes
1222
and
1224
. Finally, cam operated limit switch
531
may comprise an SPDT switch, where an inductor or solenoid
532
is connected between a second terminal
1235
of switch
531
(while terminal
1210
b
is connected to a first terminal of
1234
of switch
531
).

,

,

and

200
comprises a motor operated stored energy housing
543
, a main operator subassembly
400
and a circuit breaker adapter base or mounting plate assembly
501
. More particularly, the motor operated stored energy circuit breaker assembly
200
is adapted, attached, mounted or otherwise secured on the face or front of the circuit breaker assembly
100

519
b
so as to rotate pinion gear carrier block
536
clockwise about pivot point or shaft aperture
536
a
until a tapered or triangular end
536
c
meets and is stopped by a pinion gear carrier block stop
557
mounted in lower and upper housing
510
and
512
. If the stored energy main springs
516
a
and
516
b
are not fully charged, the gear carrier block
536
carries or moves driver/pinion gear
518
s
and idler/pinion gear
518
a
into contact with the main charging operator gear
515
. When actuated, the pinion gears
518
rotate the main charging operator gear
515
clockwise so as to move cyclically and clockwise the pin cam follower
542
within a pin or cam follower aperture
504
m
on the drive connector plate
504
so as to charge the springs
516
.
As shown in
FIG. 15
, the main charging operator gear
515
only has missing gear teeth
515
t
through in the order of about more than one-half of its circumference so that the idler/pinion gear
518
a
cooperating with the driver/pinion gear
518
s
only drives, moves or rotates the pin or cam follower
542
on the order of about a few degrees past a position that is top dead center. In particular, teeth
515
t
on the main charging operator gear
515
only cover on the order of about one-half of the operator gear circumference. In the specific embodiment, the operator gear
515
comprises twenty adjacent or contiguous operator gear teeth that fit in a thirty-two gear tooth pattern. That is, twelve gear teeth are missing from the thirty-two gear tooth pattern so that on the order of about sixty-two and one-half percent (62.5%) of the operator gear
515
has operator gear teeth so that there is almost a thirty-two and one-half percent (32.5%) gap. Also, further rotating the manual reset/charging handle
537
rotates the pinion gear carrier block
536
no more than the driver/pinion gear
518
s
. To indicate that the charging action is complete, the force required to operate the manual operator reset/charging handle
537
is noticeably reduced. When the main charging gear
515
has been driven as far as possible by the driver/pinion gear
518
s
, the force of the main charging springs
516
a
and
516
b
causes the main charging gear
515
to continue to rotate until its rotation is stopped by the D-shaped cylindrical latch assembly
640
. By moving in pin cam follower aperture
504
m
on the drive connector plate
504
, the cyclic motion of the pin cam follower
542
causes the drive connector plate
504
and the slide plate
522
to move linearly as guided by the guide or toggle slide shafts
503
a
and
503
b
. The linear motion of the drive connector plate
504
moves the circuit breaker toggle handle
103
so as to open the main contacts (not shown) of the circuit breaker assembly
100
, thereby driving the motor operated stored energy circuit breaker assembly
200
into its reset and ready to close position. The linear motion of the drive connector plate
504
and the slide plate
522
also stretches or charges the operating springs
516
a
and
516
b
which are secured between the drive connector plate
504
and the main internal housing
511
, as previously discussed. In this way, the energy stored in the operating springs
516
a
and
516
b
may later be used to quickly close the main contacts of the circuit breaker assembly
100
.

, is mounted, using any appropriate fastening or mounting apparatus, such as two screws
592
and two lockwashers
603
, on an inside surface of upper gear housing
512
using apertures
512
c
and
512
d
. Limit button switch
541
a
and limit switch
614
are also shown and described in
FIGS. 6 and 7
.
As shown in
FIGS. 1
,
2
,
13
,
15
and
16
, a cylinder lock
618
is mounted in the main external housing
543
using recessed cylinder lock aperture
5431
. Also, middle cylinder lock member
618
c
, which receives key
618
a
, is insertedly fitted through cylinder lock aperture
512
s
of upper gear housing
512
and secured using cylinder lock arm
613
, which is threadedly secured on rear cylinder lock member
618
d
, while lock base
618
b
rests inside external housing cylinder lock aperture
5431
. In particular, as shown in
FIGS. 8 and 13
, cylinder lock arm
613
has, a tapered end
613
u
having a lock arm pin aperture
613
v
, which receives an end
559
a
of lock arm pin
559
. Another end
559
b
of lock arm pin
559
is insertedly fitted in lifter aperture
552
b
of vertical lifter mounting member
552
a
of lifter
552
. Also, lifter
552
has a horizontal lifter member
552
c
, whose surface is perpendicularly oriented with respect to vertical lifter mounting member
552
a
. Additionally, horizontal lifter member
552
c
has a wider left end
552
d
which tapers to a narrower right end
552
e
, which is integrally formed with vertical lifter mounting member
552
a
. Horizontal lifter member
552
c
is insertedly fitted through horizontal lifter aperture
538
i
of locking hasp member
538
e
of locking hasp
538
. Thus, when a user turns a key
618
a
so as to rotate clockwise cylinder lock arm
613
from its left oriented horizontal position to a perpendicularly oriented position, the cylinder lock arm
613
rotateably moves lifter
552
upwardly so that horizontal lifter member
552
c
slides upwardly and transversely from left to right thereby lifting locking hasp member
538
e
of locking hasp assembly
538
to a locking position with respect to latch plate
574
.
As further regards locking hasp
538
, it comprises horizontal locking member
538
b
which is perpendicularly oriented with respect to vertical member
538
a
, as well as locking hasp securing member
538
e
, all of which are integrally formed together. Horizontal locking member
538
b
of locking hasp assembly
538
has a locking hasp aperture
538
c
for receiving a locking hasp (not shown) so as to resist unauthorized or inadvertent tampering with the circuit breaker assembly. Lockout slide
550
has a locking end
550
a
that slides into vertical lockout slide aperture
538
f
of locking hasp securing member
538
e
when a user slides the lockout slide
550
from its manual (unlocked to allow manual use) position to its automatic (locked to prevent manual use) position. Finally, hasp springs
539
a
and
539
b
are secured on each side of locking hasp member using hasp spring pin
538
r
, which fits in hasp spring pin aperture
538
j
and which projects from both sides of locking hasp securing member
538
e
. The other ends of hasp springs
539
a
and
539
b
are secured to hasp spring apertures
510
s
on lower gear housing
510
.
As shown in
FIGS. 6
to

,
18
and
24
, also mounted at the base of lower gear housing
510
is straight lever switch
614
, which is mounted using a straight lever switch bracket
549
and two pozidrive screws
592
and two lockwashers
103
at straight lever switch mounting apertures
510
cc
and
510
dd
. The button switch
614
a
of straight lever switch
614
is positioned adjacent to the vertical member
553
b
of trip rod
553
. When activated, the OFF/TRIP button
609
forces trip rod
553
forward so as to cause trip rod member
553
c
to actuate a trip button (
FIG. 24
) on the circuit breaker assembly
100
, and vertical member
553
b
actuates straight lever switch
614
so as to cause the electric motor
521
to drive the circuit breaker assembly to its OFF position, as shown in
FIGS. 6 and 7
. To avoid actuating the trip button, a screw or other suitably appropriate limit apparatus (not shown) may be mounted adjacent that vertical trip rod member
553
b
and the button switch
614
a
of straight lever switch
614
so as to limit movement of the trip rod
553
so as to allow actuation of the local OFF operation using electric motor
521
but prevent tripping of the circuit breaker assembly
100
.
A D-shaped latch assembly
640
is shown in
FIGS. 8
,
9
,
11
,
16
to
18
and
23
to
25
. As shown in the referenced Figures, the assembly
640
comprises D-shaped latch
544
, latch lever
545
, solenoid link pin
576
, roll pin
593
, dowel pin
617
, latch lever spacer
581
, latch bellcrank
561
, bellcrank return spring
560
, bellcrank pivot bushing
547
, bellcrank pivot shaft
562
and push-on retainer
587
.
Referring again to the referenced Figures, including
FIGS. 25A and 25B
, the dowel pin
617
is inserted through dowel pin receiving apertures
545
a
and
545
b
of latch lever
545
and further inserted in a dowel pin receiving aperture (not shown) of D-shaped latch
544
. The latch
544
has a D-shaped or cylindrical member
544
a
integrally associated with partial cylindrical member
544
b
having a flat surface
544
c
perpendicularly oriented with respect to semi-circular outer end surface
544
e
of partial cylindrical member
544
b
and to semi-circular end surface
544
d
of cylindrical member
544
a
. A roll pin
593
is also insertedly fitted into a roll pin aperture (not shown) in D-shaped latch
544
and the generally tapered or triangular shaped latch lever end
545
e
of latch lever
545
. The latch lever spacer
581
shown in the referenced Figures fits over the dowel pin
617
so as to space the partially cylindrical latch lever member
544
b
with respect to the inner surfaces of the upper gear housing
512
and the lower gear housing
510
. Latch lever
545
also has a rectangular shaped hasp interfering member
545
d
, which partially fits in hasp interfering aperture
5381
of hasp
538
. The hasp interfering member
545
d
is integrally associated with and is perpendicularly oriented with respect to partially semi-circular latch lever member
545
c
.
Solenoid link pin
576
is used to rotateably connect or link the tapered end of latch lever
545
to an end
533
a
(having a solenoid link pin aperture) of solenoid link
3533
. Another end
533
b
(having a solenoid plunger connecting aperture
533
d
) is operably connected or linked to a slotted aperture (not shown) at end
532
g
to solenoid cylindrical plunger
532
using a roll pin
594
and solenoid roll pin aperture
532
e
. A solenoid end
532
f
is designed to fit within a solenoid plunger
532
a
receiving aperture (not shown) of solenoid
532
b
. Solenoid spring
578
operates to apply force to the solenoid plunger
532
a
so that it moves outwardly from solenoid
532
b
and to its original position. The ON push-button switch
548
, which is used to actuate the D-latch assembly
640
and the solenoid
532
, is also returned to its original position by the force of solenoid plunger spring
578
. The solenoid
532
is mounted at an appropriate angle on the outside surface of lower gear housing
512
using solenoid mounting apertures
532
h
and
532
i
and appropriate fastening apparatus, such as screws
607
and spacer
532
s
, and lower gear solenoid mounting apertures
510
x
and
510
w.
The D-shaped latch assembly
640
operates as follows: when the operator pushes the ON push button switch
548
, it depresses push button rod
564
through push button rod aperture
512
u
of upper gear housing
512
so as to actuate latch bell crank
561
, thereby rotating D-shaped latch
544
which releases latch plate
574
so as to allow operator gear
515
to rotate, thereby allowing the charged main springs
516
to release so as to force drive connector
504
and slide plate
522
upwardly so as to move the toggle handle
103
of the circuit breaker assembly
100
from its OFF position to its ON position.
In particular, the latch bellcrank
561
comprises a mounting surface
561
a
and two perpendicular rectangular flanges, namely a push button rod flange
561
b
and a solenoid link pin flange
561
c
, as well as a rotateable bellcrank latch mounting pin aperture (not shown), which receives bellcrank lath pivot bushing
547
, bellcrank return spring
560
and bellcrank latch pivot shaft
562
, which is secured on the bellcrank latch mounting flange
512
hh
of upper gear housing
512
using push-on retainer
587
.
As discussed, the push button rod
564
pushes the push button flange
561
b
of bellcrank latch
561
so that it pivots about pivot bushing
547
, pivot shaft
562
as well as bellcrank return spring
560
which resists the clockwise rotation of bellcrank latch
561
. As the bellcrank latch rotates clockwise, solenoid link pin flange
561
c
pushes solenoid link pin
576
, located in the tapered end
545
e
of latch lever
545
so as to rotate clockwise latch
544
, dowel pin
617
and spacer
581
. In this way, the D-shaped latch member
544
b
of latch
544
also rotates clockwise so that it no longer interferes with latch stop
5741
on latch plate
574
. As a result, the latch plate
574
and the operator gear
515
may rotate, as discussed above and as shown in
FIGS. 23
to
25
.
Also, when the ON push button switch
548
is actuated so as to depress ON button rod
564
and partially rotate clockwise D-shaped latch assembly
640
, rectangular shaped hasp interfering member
545
rotates into slotted aperture
5381
of hasp
538
. In this way, hasp
538
is prevented from being removed while the stored energy circuit breaker assembly
200
moves the toggle handle
103
of the circuit breaker assembly
100
to its ON position.
As discussed, and as is shown in
FIGS. 8
,
9
,
11
,
14
to
22
, is a pinion gear assembly comprising pinion gear carrier
536
, which is used to mount driver/pinion gear
518
s
and idler/pinion gear
518
a
. Operator handle/pinion shaft aperture
510
b
in lower gear housing plate
510
is used to receive the operator handle/pinion shaft
513
. Pinion gear carrier post or stop
557
projects perpendicularly from the inside surface of lower gear housing
510
towards main housing
511
, and is used to limit rotational movement of charge gear carrier
536
, as is discussed further below. The main operator gear
515
has a kickout cam or latch plate
574
and a cam following pin or post structure
542
, which fits within cam following aperture
504
m
of drive connector
504
. Cam following pin or post structure
542
moves horizontally within cam following aperture
504
of drive connector or slide plate
504
so as to cause the drive connector or slide plate
504
to move linearly and vertically.
Also shown in
FIGS. 2
,
3
,
6
,
8
,
9
,
11
,
15
and
16
are a manual/auto lockout slide plate
550
having a locking extension member
550
a
. As discussed, locking hasp vertically slotted apertures
510
t
and
512
t
receives locking hasp
538
. Manual/auto lockout slide plate
550
has a lockout slide retainer
555
which is secured by placing securing end
555
b
in lock slide retainer aperture
550
b
using retainer
597
fitted in circumferential slot
555
c
so that button end
555
a
projects outwardly through generally oval shaped lock slide retainer aperture
512
w
of upper gear housing
512
. A manual/auto lockout slide handle
546
(secured by retainer
597
), which a user may grasp and slide horizontally to move the manual/auto slide plate
750
between its left or manual and right or automatic positions, is secured by using retainer
597
to retain securing end
546
b
in lockout slide handle aperture
550
e
and allowing handle end
546
a
to project through upper gear housing lockout slide handle aperture
512
ff
and main external housing lockout slide handle aperture
543
g
. Both lockout slide retainer
555
and manual auto lockout slide handle
546
are securely associated with lockout slide plate
550
using shoulder rivets or any other suitably appropriate securing apparatus. If the manual/auto lockout slide handle
546
is in its manual position, a user may operate OFF button
609
and ON button
548
. If the manual/auto lockout slide handle
546
is in its automatic position, then a user cannot actuate OFF button
609
or ON button
548
, which are blocked by the “automatic” position of the manual/auto lockout slide handle
550
.
OFF button
609
receives and actuates trip rod
553
through trip rod aperture
512
d
of upper gear housing
512
. ON button
548
receives and actuates ON button rod
564
through ON button rod aperture
512
u
. Also, the ON button legs
548
x
and
548
xx
fit in ON button leg apertures
512
x
and
512
xx
of upper gear housing
512
to allow ON button
548
to be depressed in the manual position when ON button leg lockout slide aperture
550
c
is aligned with ON button leg aperture
512
x
of upper gear housing
512
. When the manual/auto lockout slide plate
550
is in its first or left manual position, then the ON button
548
and the OFF button
609
cannot be depressed because the lockout slide plate
550
interferes with the depression of those buttons since the lockout slide button apertures are not aligned with the corresponding apertures in the upper gear housing
512
. When the manual/auto lockout slide is moved to the right so that it is in its automatic position, button switch flange
550
g
depresses an actuation button (not shown) of button switches
535
a
and
535
b
(see
FIG. 6
) which are also switches S

B of the electrical schematics shown in
FIGS. 6 and 7
. Thus, switches
535
a
(S
2
A) and
535
b
(S
2
B) are open when the manual/auto lockout slide
550
is in its manual position, and they are closed for automatic operation when the manual auto lockout slide
550
is in its automatic position.
Finally, the manual/auto lockout slide
550
is biased or restrained in either its manual or automatic position using two lockout slide spring pins
563
, lockout slide toggle pin
554
and lockout slide toggle spring
558
. In particular, lockout slide spring pins fit in lower and upper lockout slide spring pin apertures
512
y
while lockout slide toggle pin
554
fits in lockout slide toggle pin aperture
550
z
of lockout slide
550
and further projects through oval-shaped upper gear housing lockout slide pin aperture
512
z
. Also, each lockout slide spring pin
563
fit into lockout upper and lower slide pin spring aperture
558
y
and lockout slide toggle pin
554
fits in middle lockout slide toggle pin spring aperture
558
z
. In this way, the lockout slide
550
is biased into either its manual or automatic positions using the lockout slide toggle spring.
When the charging springs
516
a
and
516
b
are fully charged, the main contact of the circuit breaker assembly
100
may be either manually or electrically closed as follows. As discussed, pressing ON button
548
causes the D-latch assembly
544
to rotate clockwise so that latch
5741
of latch plate
574
is free to rotate clockwise past the flat surface of D-latch
544
. As discussed, this allows the main operator gear
515
to rotate and the drive connector or slide plate
504
to move relatively rapidly in an upward direction so as to force the toggle handle
103
of the circuit breaker assembly
100
to its ON position using toggle handle slide
522
.
When the charging springs
516
a
and
516
b
are not fully charged, electrical operation is as follows:
When electric power is applied, an electric motor
510
is used to drive a reduction gear assembly
630
, which rotates a worm
517
and corresponding worm gear
507
, which drives handle/pinion shaft
513
through unidirectional clutches
519
a
and
519
b
as previously discussed. The shaft
513
rotates until charge gear carrier
536
is stopped by the charge gear block stop
557
a
. The charge gear carrier
536
carries driver/pinion gear
518
s
and idler/pinion gear
518
a
into contact with a main charging or operator gear
515
if the stored energy operating mechanism or charging springs
516
a
and
516
b
are not fully charged. The idler/pinion gear
518
a
then rotates the main charging gear
515
clockwise so as to carry the pin/cam follower
542
in a cyclic motion, which is translated into linear motion of the drive connector or slide plate
504
. The main charging gear
515
has twelve teeth
515
t
missing out of a thirty-two gear tooth pattern so that the idler/pinion gear
518
a
is only able to drive the main charging gear
515
to a point or position where the pin/cam follower
542
has been carried a few degrees past the position of top dead center of the main operator gear
515
or in the proper overcenter position. This also allows the electric motor
521
to coast to its resting position so that it is not necessary to electrically or mechanically brake the electric motor
521
.
When the main charging gear
515
has been driven as far as the idler/pinion and driver/pinion gears
518
a
518
s
may drive it, the force of the operating springs
516
a
and
516
b
causes it to continue to rotate until the latch
5741
of latch plate
574
catches D-latch
544
so as to stop its rotation. By moving laterally in a horizontal slot operator
504
m
in the drive connector or slide plate
504
, the cyclic motion of the pin/cam follower
542
causes the drive connector
504
and the toggle handle slide
522
to move linearly as guided by the guide rods or slide shafts
503
a
and
503
b
. The linear motion of the drive connector
504
moves the toggle handle
103
of the circuit breaker assembly
100
so as to open the main contacts of the circuit breaker assembly
100
. The linear motion of the drive connector
522
also stretches or charges the charging springs
516
a
and
516
b
, which are attached, secured or otherwise fastened between slotted apertures of drive connector
504
and anchor points of main housing assembly plate
511
as previously discussed. In this way, the energy stored in the charging operating springs
516
may be used to close relatively rapidly the main contacts of the circuit breaker assembly
100
by forcing the circuit breaker toggle handle
101
to its ON position.
