（1）固定面板(ban)(ban)式(shi)(shi)开(kai)关柜，常称开(kai)关板(ban)(ban)或配电(dian)屏。它是(shi)一(yi)种有面板(ban)(ban)遮拦的敞开(kai)式(shi)(shi)开(kai)关柜，正(zheng)面有防护作用(yong)，反面和旁(pang)边(bian)面仍能触及带电(dian)部分，防护等级低，只能用(yong)于对供电(dian)连续性(xing)和可靠(kao)性(xing)要求较(jiao)低的工矿企业，作变电(dian)室会集供电(dian)用(yong)。

（2）防护(hu)式(shi)（即关(guan)(guan)(guan)闭(bi)式(shi)）开关(guan)(guan)(guan)柜(ju)(ju)，指除装(zhuang)置(zhi)(zhi)面(mian)外(wai)，其它一(yi)(yi)切(qie)旁边面(mian)都被关(guan)(guan)(guan)闭(bi)起来的(de)一(yi)(yi)种低压开关(guan)(guan)(guan)柜(ju)(ju)。这(zhei)种柜(ju)(ju)子(zi)的(de)开关(guan)(guan)(guan)、维护(hu)和监测(ce)操(cao)(cao)控(kong)等电(dian)气元件，均装(zhuang)置(zhi)(zhi)在一(yi)(yi)个用钢或(huo)绝(jue)缘(yuan)材料制成的(de)关(guan)(guan)(guan)闭(bi)外(wai)壳(qiao)内(nei)，可(ke)靠墙或(huo)离墙装(zhuang)置(zhi)(zhi)。柜(ju)(ju)内(nei)每条回路之(zhi)间能够不(bu)加(jia)阻(zu)隔办法，也能够选用接地的(de)金属板或(huo)绝(jue)缘(yuan)板进行阻(zu)隔。一(yi)(yi)般门与主(zhu)开关(guan)(guan)(guan)操(cao)(cao)作(zuo)有(you)机(ji)械(xie)联(lian)锁。另(ling)外(wai)还有(you)防护(hu)式(shi)台型开关(guan)(guan)(guan)柜(ju)(ju)（即操(cao)(cao)控(kong)台），面(mian)板上(shang)装(zhuang)有(you)操(cao)(cao)控(kong)、测(ce)量、信号等电(dian)器(qi)。防护(hu)式(shi)开关(guan)(guan)(guan)柜(ju)(ju)首要(yao)用作(zuo)工艺(yi)现场的(de)配(pei)电(dian)装(zhuang)置(zhi)(zhi)。

（3）抽(chou)(chou)屉式开关(guan)柜(ju)(ju)。这类开关(guan)柜(ju)(ju)选用钢板(ban)制成(cheng)关(guan)闭(bi)外壳(qiao)，进出线回路的电(dian)(dian)器元(yuan)(yuan)件都装置在可(ke)抽(chou)(chou)出的抽(chou)(chou)屉中，构成(cheng)能完(wan)成(cheng)某一类供(gong)电(dian)(dian)任务的功(gong)用单元(yuan)(yuan)。功(gong)用单元(yuan)(yuan)与母线或电(dian)(dian)缆之间，用接地的金属板(ban)或塑料制成(cheng)的功(gong)用板(ban)离隔，形成(cheng)母线、功(gong)用单元(yuan)(yuan)和电(dian)(dian)缆三个(ge)区域。每个(ge)功(gong)用单元(yuan)(yuan)之间也有阻隔办法。抽(chou)(chou)屉式开关(guan)柜(ju)(ju)有较(jiao)高(gao)(gao)的可(ke)靠(kao)性(xing)(xing)、安全性(xing)(xing)和互换(huan)性(xing)(xing)，是比(bi)较(jiao)优良的开关(guan)柜(ju)(ju)，开关(guan)柜(ju)(ju)多数(shu)是指抽(chou)(chou)屉式开关(guan)柜(ju)(ju)。它们适(shi)用于要求供(gong)电(dian)(dian)可(ke)靠(kao)性(xing)(xing)较(jiao)高(gao)(gao)的工矿企(qi)业、高(gao)(gao)层建筑，作为(wei)会(hui)集操控的配(pei)电(dian)(dian)中心。

（4）动(dong)力、照明(ming)配电(dian)操(cao)控箱。多(duo)为(wei)关(guan)闭(bi)式垂(chui)直装(zhuang)置。因运(yun)用场(chang)合不同，外壳(qiao)防护(hu)等级也不同。它们首(shou)要作为(wei)工矿企业出(chu)产(chan)现场(chang)的配电(dian)装(zhuang)置。
