 GW9高壓隔離開(kāi)關(guān)保證裝置檢修工作的安全性
 
    GW9高壓隔離開(kāi)關(guān)是發(fā)電廠(chǎng)和變電站電氣系統中重要的開(kāi)關(guān)電器，需與高壓斷路器配套使用。
GW9高壓隔離開(kāi)關(guān)主要功能是：保證高壓電器及裝置在檢修工作時(shí)的安全，起隔離電壓的作用，不能用與切斷、投入負荷電流和開(kāi)斷短路電流，僅可用于不產(chǎn)生強大電弧的某些切換操作，即是說(shuō)它不具有滅弧功能；按安裝地點(diǎn)不同分為，屋內式和屋外式，按絕緣支柱數目分為，單柱式，雙柱式和三柱式，各電壓等級都有可選設備。 
GW9高壓隔離開(kāi)關(guān)作用：
　　GW9高壓隔離開(kāi)關(guān)保證了高壓電器及裝置在檢修工作時(shí)的安全，起隔離電壓的作用，不能用與切斷、投入負荷電流和開(kāi)斷短路電流，僅可用于不產(chǎn)生強大電弧的某些切換操作，即是說(shuō)它不具有滅弧功能；按安裝地點(diǎn)不同分為，屋內式和屋外式，按絕緣支柱數目分為，單柱式，雙柱式和三柱式，各電壓等級都有可選設備。還可將高壓配電裝置中需要停電的部分與帶電部分可靠地隔離，以保證檢修工作的安全。GW9高壓隔離開(kāi)關(guān)的觸頭全部敞露在空氣中，具有明顯的斷開(kāi)點(diǎn)，隔離開(kāi)關(guān)沒(méi)有滅弧裝置，因此不能用來(lái)切斷負荷電流或短路電流，否則在高壓作用下，斷開(kāi)點(diǎn)將產(chǎn)生強烈電弧，并很難自行熄滅，甚至可能造成飛?。ㄏ鄬Φ鼗蛳嚅g短路），燒損設備，危及人身安全，這就是所謂“帶負荷拉隔離開(kāi)關(guān)”的嚴重事故。
