Abstract:
A vacuum circuit breaker includes a movable-side conductor that is tubular and comprises an inside cavity. A movable side contact case includes a chamber which communicates with a space on a non-vacuum side of a bellows. The chamber is isolated from a space filled with insulating gas in a ground tank by a sealing device. The chamber communicates with an outside atmosphere through the inside cavity of the movable-side conductor.
