按(an)照電(dian)壓等級分類通常將AC1000V及以下稱為低(di)壓開關(guan)柜（如PGL、GGD、GCK、GBD、MNS等）。開關(guan)柜柜體選用(yong)冷軋鋼經數(shu)控鈑金加工成(cheng)形(xing)后，通過高強度螺(luo)栓(shuan)螺(luo)母(mu)(mu)和(he)鉚螺(luo)母(mu)(mu)連接(jie)而成(cheng)，構件表(biao)面采(cai)用(yong)噴塑或鍍(du)鋅工藝。開關(guan)柜（switchgear）的主要作(zuo)用(yong)是在(zai)電(dian)力系統進行發電(dian)、輸(shu)電(dian)、配(pei)電(dian)和(he)電(dian)能轉換的過程(cheng)中(zhong)，進行開合(he)、控制(zhi)和(he)保(bao)護用(yong)電(dian)設(she)備。

高壓(ya)(ya)(ya)(ya)(ya)開(kai)關(guan)(guan)柜(ju)(ju)(ju)按(an)作電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級在3。6kV~550kV的(de)電(dian)(dian)器產品，高壓(ya)(ya)(ya)(ya)(ya)隔離(li)開(kai)關(guan)(guan)與(yu)接地開(kai)關(guan)(guan)、高壓(ya)(ya)(ya)(ya)(ya)負荷開(kai)關(guan)(guan)、高壓(ya)(ya)(ya)(ya)(ya)自動(dong)重合與(yu)分段器，高壓(ya)(ya)(ya)(ya)(ya)操作機構(gou)、高壓(ya)(ya)(ya)(ya)(ya)防爆配電(dian)(dian)裝置和高壓(ya)(ya)(ya)(ya)(ya)開(kai)關(guan)(guan)柜(ju)(ju)(ju)等幾大類(lei)。按(an)用(yong)途分類(lei)：進線柜(ju)(ju)(ju)、出線柜(ju)(ju)(ju)、計量柜(ju)(ju)(ju)、補償柜(ju)(ju)(ju)（電(dian)(dian)容柜(ju)(ju)(ju)）、轉(zhuan)角柜(ju)(ju)(ju)、母線柜(ju)(ju)(ju)。送電(dian)(dian)操作步驟：先裝好(hao)后封板，再關(guan)(guan)好(hao)前下(xia)門。高壓(ya)(ya)(ya)(ya)(ya)開(kai)關(guan)(guan)柜(ju)(ju)(ju)是指用(yong)于電(dian)(dian)力(li)系(xi)統發電(dian)(dian)、輸(shu)電(dian)(dian)、配電(dian)(dian)、電(dian)(dian)能轉(zhuan)換和消耗中起通斷、控制(zhi)或保護等作用(yong)。

開(kai)(kai)(kai)關柜(ju)(ju)(ju)柜(ju)(ju)(ju)體(ti)選用(yong)冷軋鋼經數控鈑金加工成形后，通過高(gao)強度螺(luo)栓螺(luo)母和鉚螺(luo)母連(lian)接(jie)而成，構件(jian)表面采用(yong)噴塑或(huo)鍍鋅工藝。采用(yong)熱縮絕緣材(cai)料及(ji)環氧(yang)涂覆絕緣工藝，優化電(dian)極(ji)形狀，開(kai)(kai)(kai)關柜(ju)(ju)(ju)廠(chang)家，柜(ju)(ju)(ju)體(ti)結構緊(jin)湊，縮小(xiao)占地面積；當開(kai)(kai)(kai)關柜(ju)(ju)(ju)使用(yong)條件(jian)超出(chu)以上(shang)規定(ding)(ding)，由用(yong)戶與制造(zao)廠(chang)協商確定(ding)(ding)。按電(dian)壓(ya)波形分類：分為(wei)：交流(liu)開(kai)(kai)(kai)關柜(ju)(ju)(ju)、直流(liu)開(kai)(kai)(kai)關柜(ju)(ju)(ju)。按內部結構分類：抽出(chu)式開(kai)(kai)(kai)關柜(ju)(ju)(ju)（如(ru)GCS、GCK、MNS等）、固定(ding)(ding)式開(kai)(kai)(kai)關柜(ju)(ju)(ju)（如(ru)GGD等）。
