摘要： A vacuum exhaust element of a vacuum switch has an ordinary withstand voltage because the vacuum vessel and power source element are grounded, therefore not requiring the high voltage to be taken into consideration. This way, the vacuum exhaust element is miniaturized and it is safe for a worker to touch the vacuum vessel and the vacuum exhaust element when performing maintenance and/or inspection.

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.
摘要翻译：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。

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： There is disclosed a vacuum insulation switch provided with a movable electrode, a stationary electrode and an earthing electrode, which are insulated from each other, in a vacuum container made of a conductive material which is earthed, and a switchgear using the same. Since the vacuum insulation, which is excellent in the insulation ability, is utilized, the switch is drastically miniaturized and the number of constituent parts are reduced, whereby the manufacturing cost of the switch and the switchgear can be decreased.
