摘要： In a vacuum type switch gear device an L shaped stationary and movable conductors arrangement, a transitive portion from one spiral arc groove to a neighboring another spiral arc groove on the surface of a movable electrode defined by the terminating end portion of the one spiral groove, the starting end of the adjacent neighboring other spiral groove and the outer circumferential edge portion of the movable electrode is arranged in a substantially overlapping relationship in a vertical direction with the movable conductor. Thus an adverse effect of a current loop flowing through the movable conductor against an arc generated between movable and stationary electrodes is limited to thereby improve the circuit breaking performance.

摘要： In an insulated type switchgear device in which a pair of arc electrodes are separably disposed in an opposing manner in a vacuum tube, and having a movable conductor extending from a back face of a movable one of the arc electrodes to the outside of the vacuum tube, the pair of arc electrodes are designed to be separated through a rotation of the movable conductor around a predetermined main axis. The movable arc electrode is structured in such a manner that an electrode center of the movable arc electrode, when the movable arc electrode is brought into its circuit breaking position, is to be located near a center axis of the stationary arc electrode, whereby the center of the movable arc electrode is offset from the center axis of the stationary arc electrode when the pair of arc electrodes are brought into their circuit making position, and whereby an insulation type switchgear device is provided which suppresses a possible offsetting of arc electrodes at a circuit breaking position thereof, improves circuit breaking performance thereof, and permits downsizing thereof.
