按(an)電壓(ya)(ya)波形分(fen)類(lei)：分(fen)為：交流開(kai)關柜(ju)、直流開(kai)關柜(ju)。按(an)內(nei)部結構(gou)分(fen)類(lei)：抽出式開(kai)關柜(ju)（如(ru)GCS、GCK、MNS等(deng)）、固定式開(kai)關柜(ju)（如(ru)GGD等(deng)）。額定絕(jue)緣水平（1min工(gong)頻耐壓(ya)(ya)：相間、相對(dui)的95KV，一(yi)次隔離(li)斷口(kou)(kou)115KV。雷電沖擊耐受(shou)電壓(ya)(ya)：相間、相對(dui)的185KV，開(kai)關柜(ju)廠，一(yi)次隔離(li)斷口(kou)(kou)215KV。輔助(zhu)控制回路1min工(gong)頻耐壓(ya)(ya)：2KV）。高壓(ya)(ya)開(kai)關柜(ju)內(nei)的真空斷路器在工(gong)作合(he)閘運行(xing)時，無法退出小車斷路器的工(gong)作位(wei)置。（防止帶負荷拉刀閘）。

AC1000V以上稱為(wei)高壓(ya)(ya)開關柜(ju)（如GG-1A、XGN15、KYN48等），有時也將高壓(ya)(ya)柜(ju)中(zhong)(zhong)電(dian)(dian)壓(ya)(ya)為(wei)AC10kV的稱為(wei)中(zhong)(zhong)壓(ya)(ya)柜(ju)（如XGN15型10kV環網(wang)柜(ju)）。如儀(yi)表，自控，電(dian)(dian)動機(ji)磁力(li)開關，各種交流(liu)接觸器(qi)等，有的還(huan)設(she)(she)高壓(ya)(ya)室與(yu)低壓(ya)(ya)室開關柜(ju)，設(she)(she)有高壓(ya)(ya)母(mu)線，如發電(dian)(dian)廠(chang)等，有的還(huan)設(she)(she)有為(wei)保主要設(she)(she)備的低周減載。高壓(ya)(ya)開關柜(ju)是指用于(yu)電(dian)(dian)力(li)系統發電(dian)(dian)、輸電(dian)(dian)、配電(dian)(dian)、電(dian)(dian)能轉換和消(xiao)耗中(zhong)(zhong)起(qi)通斷、控制或保護等作(zuo)用。
