    • 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.
    • 在一种绝缘型开关装置中,其中一对电弧电极以相对的方式可分离地设置在真空管中,并且具有从可动的一个电弧电极的背面延伸到真空管的外部的可动导体 一对电弧电极被设计成通过可移动导体围绕预定的主轴线的旋转分开。 可动电弧电极的结构使得当可动电弧电极进入其断路位置时,可动电弧电极的电极中心位于固定电弧电极的中心轴附近,由此中心 当一对电弧电极进入其电路制造位置时,可动电弧电极的距离偏离固定电弧电极的中心轴线,由此提供了一种绝缘型开关装置,其抑制了电路中的电弧电极的可能的偏移 断开位置,提高断路性能,并且能够实现小型化。
