Abstract (en)
[origin: US4965419A] A metal-clad, compressed gas-blast circuit-breaker having a gas-filled housing and an interrupter unit supported in the housing by a hollow post insulator. The circuit-breaker has a shifting linkage with at least one insulating drive rod, the shifting linkage transmitting the switching motion from a driving mechanism to a movable switching contact. In order to reduce the overall axial length of the circuit-breaker, the hollow post insulator comprising only insulating material, is penetrated only by the insulating drive rod and has, for fixing to the housing, on an end area facing away from the interrupter unit, on an outside surface, a premolded flanged ring mounted set back axially from the edge and being adapted to the bearing ring of the housing. The described circuit-breaker is esepcially suited for application in gas-insulated, metal-clad, high-voltage switching stations.
