摘要： In a double-break type circuit breaker having resistor contacts which are to be connected in parallel with main contacts in not only closing operation but also breaking operation, the resistor contacts are opened by a force due to loading of elastic members in the breaking operation and the elastic members are loaded for storing the driving force In the closing operation.

摘要： 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.
