摘 要：接地開關(guān)是將回路接地，在異常條件下，可以承載規(guī)定時(shí)間內(nèi)規(guī)定的短路電流，在某些工況下還需要具有關(guān)合短路電流或開合感應(yīng)電流的功能。介紹了接地開關(guān)的特點(diǎn)及性能，對(duì)接地開關(guān)從本體結(jié)構(gòu)及操動(dòng)機(jī)構(gòu)兩方面進(jìn)行優(yōu)化：本體設(shè)置分合閘指示裝置，操動(dòng)機(jī)構(gòu)設(shè)置“雙確認(rèn)”裝置，兩種優(yōu)化設(shè)計(jì)大大提高了接地開關(guān)的安全可靠性。
關(guān)鍵詞：氣體絕緣金屬封閉開關(guān)設(shè)備；接地開關(guān)；操動(dòng)機(jī)構(gòu)；分合閘指示裝置；雙確認(rèn)裝置

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
