ABSTRACT:
In a stationary contact unit of a gas circuit breaker, an arc-quenching cylinder for passing an arc-quenching insulation gas is formed in a substantially semicircular shape, and the stationary contact unit is supported by an insulation frame which is disposed beneath the dent part of the semicircular portion of the arc-quenching cylinder. The insulation frame is prevented from the degradation of dielectric strength between the stationary contact unit and a grounded tank, and the size of the gas circuit breaker is decreased.
