摘要： There have been demands for wear of the contact surfaces of the movable and fixed electrodes of a vacuum circuit breaker to be reduced, for the withstand voltage capability and the shutoff capability between the electrodes to be improved, and for service life to be extended. Disclosed is a vacuum circuit breaker in which is constructed a valve body (10) with a fixed electrode (12) affixed to the end of a live conductor (13) and a movable electrode (15) affixed to the end of a live conductor (16) inside an insulated container (11), which maintains a vacuum. The operating system which operates the live conductor (13) of the movable electrode (15) is provided with a compression spring (20), and an auxiliary compression spring (21) that increases the initial separation speed of the movable electrode (15). The auxiliary compression spring (21) is disposed such that spring pressure energizing ends during shutoff operation by the movable electrode (15) and such that spring pressure accumulation begins during the turn-on operation.
