Abstract
A tank-type vacuum circuit breaker includes: a pressure tank; an insulating frame that is detachably supported by a support member provided in the pressure tank using a coupling; a vacuum interrupter that is supported by the insulating frame and includes a stationary electrode and a moving electrode; a stationary-electrode side terminal that is connectably/disconnectably connected to a bushing-terminal side internal conductor; a moving-electrode side terminal that is connectably/disconnectably connected to a bushing-terminal side internal conductor; and an insulating rod, the inside end of which is detachably coupled to the moving electrode and the outside end of which is coupled to an opening/closing actuation mechanism that opens/closes the contacts of the stationary contact and moving contact. The vacuum interrupter, the stationary-electrode side terminal, the moving-electrode side terminal and the insulating frame are integrated into a unit, and the unit can be removed and mounted by disconnecting the connections and the couplings.
