    摘 要:接地开关是将回路接地,在异常条件下,可以承载规定时间内规定的短路电流,在某些工况下还需要具有关合短路电流或开合感应电流的功能。介绍了接地开关的特点及性能,对接地开关从本体结构及操动机构两方面进行优化:本体设置分合闸指示装置,操动机构设置“双确认”装置,两种优化设计大大提高了接地开关的安全可靠性。

    Abstract: The earthing switch is to ground the circuit loop. It can carry the specified short-circuit current within a specified time under the abnormal circumstance. It also needs to have the function of closing short-circuit current or opening induced current under some working conditions. This article introduced characteristics and functions of the earthing switch, optimizing it from two aspects: structure and operating mechanism. It provides a designed opening and closing indicator device for the main body of the earthing switch and a double confirmation device for the operating mechanism. The result shows that this plan improves the safety and reliability of the grounding switch.
    Key words: GIS; earthing switch; operating mechanism; opening and closing indicating device; double confirmation device
