1、高壓開(kāi)關(guān)柜內(nèi)的真空斷路器小車在試驗(yàn)位置合閘后，小車斷路器無(wú)法進(jìn)入工作位置。（防止帶負(fù)荷合閘） 2、高壓開(kāi)關(guān)柜內(nèi)的接地刀在合位時(shí)，小車斷路器無(wú)法進(jìn)合閘。（防止帶接地線合閘） 3、高壓開(kāi)關(guān)柜內(nèi)的真空斷路器在合閘工作時(shí)，盤柜后門用接地刀上的機(jī)械與柜門閉鎖。（防止誤入帶電間隔） 4、高壓開(kāi)關(guān)柜內(nèi)的真空斷路器在工作時(shí)合閘，合接地刀無(wú)法投入。（防止帶電掛接地線） 5、高壓開(kāi)關(guān)柜內(nèi)的真空斷路器在工作合閘運(yùn)行時(shí)，無(wú)法退出小車斷路器的工作位置。（防止帶負(fù)荷拉刀閘）</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
