摘 要：接地開關是將回路接地，在異常條件下，可以承載規(guī)定時間內規(guī)定的短路電流，在某些工況下還需要具有關合短路電流或開合感應電流的功能。介紹了接地開關的特點及性能，對接地開關從本體結構及操動機構兩方面進行優(yōu)化：本體設置分合閘指示裝置，操動機構設置“雙確認”裝置，兩種優(yōu)化設計大大提高了接地開關的安全可靠性。
關鍵詞：氣體絕緣金屬封閉開關設備；接地開關；操動機構；分合閘指示裝置；雙確認裝置

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
