Claims
- 1. A high-voltage power breaker, comprising:an interrupter unit which is enclosed, with a gap, by a gas-tight housing filled with quenching gas, the interrupter unit comprising: two arcing contacts, at least one of which can be driven during a switching operation and an arc produced between the arcing contacts during disconnection being blown by a blowing device with the quenching gas, which afterwards at least partially flows away in the axial direction of the arcing contacts; a flow deflection device provided in an outlet-flow area of the quenching gas, in order to deflect the quenching gas flow through more than 90° radially outward; and a partition wall to separate the quenching gas flow before the deflection from the quenching gas flow after the deflection; wherein a nozzle body is arranged on the partition wall, and, together with the flow deflection device, forms a nozzle constriction.
- 2. The high-voltage power breaker as claimed in claim 1,wherein the nozzle body has a convex area, which faces a concave area of the flow deflection device.
- 3. The high-voltage power breaker as claimed in claim 2,wherein the flow direction device and the partition wall are cylindrically symmetrical, and are arranged coaxially with respect to the arcing contacts.
- 4. The high-voltage power breaker as claimed in claim 1,further comprising a quenching gas cooling device in the form of a body having through-openings is arranged downstream of the deflection device.
- 5. The high-voltage power breaker as claimed in claim 4, wherein the quenching gas cooling device is cylindrically symmetrical.
- 6. The high-voltage power breaker as claimed in claim 5,wherein another deflection device for the quenching gas is arranged downstream of the quenching gas cooling device.
- 7. The high-voltage power breaker as claimed in claim 1,wherein the flow deflection device and/or the nozzle body are/is composed of an insulating material.
- 8. The high-voltage power breaker as claimed in claim 4,a further deflection device for the quenching gas is arranged downstream of the quenching gas cooling device.
