Automatic on-off apparatu for ltigh-voltage circuit

An automatic switch for high-voltage circuit features that it con be remotely controlled to automatically turn-off or close the high-voltage circuit and the high-voltage circuit can be automatically broken when load is shorted. It is composed of remote control, over-current protector, motor, and rack bar. 本发明公开了一种高压电路自动分合器，它不仅能远距离遥控高压电路自动断开和闭合，还能在负载发生短路时使高压电路自动断路。本发明是由遥控电路自动控制电机(10)转动，带动齿条(13)，切断和闭合高压电路；由过流保护电路控制电机(10)转动，带动齿条(13)，切断高压电路。该产品结构简单，使用方便安全，广泛用于高压输电线路，并能大大提高供电系统的管理水平。
