電(dian)力配(pei)電(dian)柜是(shi)指用(yong)于(yu)電(dian)力系統發電(dian)、輸(shu)電(dian)、配(pei)電(dian)、電(dian)能轉換和消(xiao)耗中起通斷(duan)(duan)、控制(zhi)或(huo)保(bao)護等(deng)作用(yong),電(dian)壓(ya)(ya)(ya)等(deng)級在3.6kV~550kV的(de)電(dian)器產品(pin),主要包括高壓(ya)(ya)(ya)斷(duan)(duan)路器、高壓(ya)(ya)(ya)隔離開(kai)(kai)關(guan)與接地開(kai)(kai)關(guan)、高壓(ya)(ya)(ya)負(fu)荷開(kai)(kai)關(guan)、高壓(ya)(ya)(ya)自(zi)動(dong)重合與分段器,高壓(ya)(ya)(ya)操作機構、高壓(ya)(ya)(ya)防(fang)爆配(pei)電(dian)裝置和高壓(ya)(ya)(ya)開(kai)(kai)關(guan)柜等(deng)幾大類.高壓(ya)(ya)(ya)開(kai)(kai)關(guan)制(zhi)造業是(shi)輸(shu)變電(dian)設備制(zhi)造業的(de)重要組(zu)成部分,在整個電(dian)力工業中占有非常(chang)重要的(de)地位.

儀表(biao)配(pei)(pei)電(dian)(dian)柜的(de)(de)分級(ji):（1）一級(ji)配(pei)(pei)電(dian)(dian)設(she)備(bei),統稱為動力配(pei)(pei)電(dian)(dian)中心(xin).它(ta)們集中安裝在(zai)企(qi)業的(de)(de)變電(dian)(dian)站,把電(dian)(dian)能分配(pei)(pei)給不同(tong)地點的(de)(de)下級(ji)配(pei)(pei)電(dian)(dian)設(she)備(bei).這一級(ji)設(she)備(bei)僅靠降(jiang)壓(ya)變壓(ya)器,故電(dian)(dian)氣參數要求(qiu)較高(gao),輸出電(dian)(dian)路容量也較大.
