Patent ID: 8263892

Claim:
A gas-insulated high-voltage switch comprising: two contact members configured to be moved relative to one another along an axis; a nozzle, which is attached to a first one of the two contact members, and configured to blow out a switching arc with quenching gas; and a stationary direction-changing transmission which is connected to the nozzle and to the second one of the contact members, wherein: the nozzle comprises a hollow insulating body, which forms a constriction and at least one section of a diffuser, the section being adjacent to the constriction; the nozzle further comprises a metallic annular body which is arranged at a blowing-out end of the nozzle, which is connected in a formfitting manner to the insulating body and which supports one of an input drive element and an output drive element of the direction-changing transmission; and the annular body of the nozzle comprises a concentrically arranged intermediate ring, which causes the form fit with the insulating body, and a supporting ring for supporting the one of the input drive element and the output drive element, the supporting ring being pushed onto the intermediate ring and being attached to the intermediate ring.
