Grounded support tank type gas circuit breaker

摘要

A grounded support tank type gas circuit breaker comprising a cylindrical tank maintained at ground potential and filled with an arc-extinguishing gas, and a breaking unit disposed within the tank with its central axis extending along the axis of the tank. In the circuit breaker, a capacitor unit is disposed within the tank in axially aligned relation with the breaking unit with its axis extending along an extension of the central axis of the breaking unit, so that the capacitor unit can be easily incorporated in the circuit breaker by merely increasing the axial length of the tank.
