高壓配電柜是指用(yong)(yong)于電(dian)(dian)(dian)力(li)系(xi)統發(fa)電(dian)(dian)(dian)、輸電(dian)(dian)(dian)、配電(dian)(dian)(dian)、電(dian)(dian)(dian)能轉換和(he)消耗中(zhong)起通斷、控(kong)制(zhi)或保(bao)護等作用(yong)(yong)，電(dian)(dian)(dian)壓(ya)等級在(zai)3.6kV~550kV的(de)電(dian)(dian)(dian)器產品，主要包括高(gao)壓(ya)斷路器、高(gao)壓(ya)隔離開(kai)(kai)關(guan)(guan)(guan)與接地開(kai)(kai)關(guan)(guan)(guan)、高(gao)壓(ya)負荷開(kai)(kai)關(guan)(guan)(guan)、高(gao)壓(ya)自動重(zhong)合(he)與分(fen)段(duan)器，高(gao)壓(ya)操作機構、高(gao)壓(ya)防爆配電(dian)(dian)(dian)裝(zhuang)置和(he)高(gao)壓(ya)開(kai)(kai)關(guan)(guan)(guan)柜等幾大類。高(gao)壓(ya)開(kai)(kai)關(guan)(guan)(guan)制(zhi)造(zao)業是輸變電(dian)(dian)(dian)設備制(zhi)造(zao)業的(de)重(zhong)要組(zu)成部分(fen)，在(zai)整個電(dian)(dian)(dian)力(li)工業中(zhong)占有非常重(zhong)要的(de)地位。

功(gong)能(neng)：配(pei)電柜具(ju)有(you)架空進出(chu)線(xian)、電纜進出(chu)線(xian)、母線(xian)聯絡等功(gong)能(neng)。

結構：柜體(ti)系用薄鋼(gang)板及角鋼(gang)焊接而(er)成，底(di)座由槽鋼(gang)焊接而(er)成，柜前面有(you)單扇(shan)防護網(wang)門，后(hou)面有(you)雙扇(shan)防護網(wang)門，頂部母線敞(chang)露。

柜分前后兩(liang)室(shi)，前室(shi)裝有(you)(you)備(bei)用(起動)母線隔離(li)開(kai)關(guan)，線路隔離(li)開(kai)關(guan)及(ji)電(dian)(dian)纜頭等，前室(shi)頂部(bu)(bu)裝有(you)(you)備(bei)用(起動)母線。后室(shi)裝有(you)(you)主(工(gong)作(zuo))母線隔離(li)開(kai)關(guan)，油斷路器(qi)，頂部(bu)(bu)裝有(you)(you)主(工(gong)作(zuo))母線隔離(li)開(kai)關(guan)，前后室(shi)之(zhi)間下部(bu)(bu)可安裝電(dian)(dian)流互(hu)感器(qi)。油斷路器(qi)和隔離(li)開(kai)關(guan)操作(zuo)機構裝在(zai)柜的(de)(de)前面，柜的(de)(de)后面左側有(you)(you)一單扇(shan)鋼板門，門內是繼電(dian)(dian)器(qi)室(shi)。各室(shi)之(zhi)間，一次(ci)電(dian)(dian)器(qi)設(she)備(bei)和二(er)次(ci)電(dian)(dian)器(qi)設(she)備(bei)之(zhi)間均(jun)有(you)(you)薄(bo)鋼板隔離(li)。可以在(zai)一次(ci)電(dian)(dian)器(qi)設(she)備(bei)不停電(dian)(dian)的(de)(de)情況下檢修二(er)次(ci)電(dian)(dian)器(qi)設(she)備(bei)。

為防止工(gong)作人(ren)員(yuan)誤操作，柜上裝有程序性(xing)的電氣聯(lian)鎖裝置。
