Claims
- 1. A drive device for an interrupter, comprising:
a fixed and a movable contact part, the movable contact part being controlled by a plastic switching rod such that the switching rod in the connected and disconnected state of the contact parts is substantially not subjected to a force of a contact spring, and the force of the contact spring in the connected state of the contact parts acts almost entirely on the movable contact part, wherein
the drive device has drive levers with a triangular contour which are fitted in each corner region with a respective pivot bearing and each have a central pivot bearing for accommodating the contact spring which is mounted such that it can pivot, the central pivot bearing being arranged between an upper pivot bearing which is connected to the switching rod and a lower pivot bearing which is connected to the drive of the movable contact part, and the contact spring being mounted at one end in a stationary collar guide, and configured for the contact pressure force for the drive of the movable contact part to be regulated by altering an active path length of the contact spring, and configured to adjust the active path length of the contact spring in a stepless manner by a regulating a screw which is accessible from the outside.
- 2. A drive device for an interrupter, comprising a fixed and a movable contact part, wherein drive levers are arranged centrally symmetrically with respect to a switching rod, and in that a drive of a movable contact part surrounds the drive levers centrally symmetrically with a u-profile which is open at a bottom.
