Abstract
A high-voltage gas-type circuit-interrupter is provided utilizing a pair of serially-related puffer-type circuit-interrupters mechanically connected together, and operated by a single common operating rod. The stationary contact structures may be supported by rods attached to the interrupter support plate, or, alternatively, by a pair of terminal-bushings extending downwardly interiorly within a surrounding metallic tank at ground potential, for example. The operating arrangement may be such as to involve a linearly movable generally vertically extending common operating rod actuated externally of the grounded gas-filled tank by a suitable operating mechanism. Preferably, the individual puffer-type gas interrupters each involves the linear-slidable operation of a movable operating gas-compression cylinder, carrying the movable contact structure and an insulating nozzle orifice movable over a relatively stationary fixed piston structure.
