根據電(dian)(dian)(dian)(dian)氣(qi)設(she)備(bei)的接(jie)線規定(ding)，接(jie)線盒可(ke)(ke)安(an)裝在封(feng)閉或(huo)半(ban)封(feng)閉的金屬外(wai)殼中或(huo)屏幕(mu)上，以形成配(pei)電(dian)(dian)(dian)(dian)室(shi)設(she)備(bei)。如果(guo)一(yi)切(qie)正(zheng)(zheng)常(chang)，可(ke)(ke)以使用(yong)(yong)手或(huo)控(kong)制開關連接(jie)或(huo)斷開電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常(chang)見的錯誤或(huo)異常(chang)取(qu)決(jue)于家用(yong)(yong)電(dian)(dian)(dian)(dian)器的維護(hu)，以斷開電(dian)(dian)(dian)(dian)路或(huo)警報。識別儀可(ke)(ke)以在信息模式下(xia)顯示各種主要(yao)參(can)數，還(huan)可(ke)(ke)以調整某些電(dian)(dian)(dian)(dian)氣(qi)設(she)備(bei)的主要(yao)參(can)數，并提醒(xing)或(huo)發出所有正(zheng)(zheng)常(chang)工作設(she)置的偏差信號(hao)。常(chang)用(yong)(yong)于發電(dian)(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站(zhan)。

涉及電源系統中發電，傳輸，分配，轉換和功耗中的接通和斷開，控制或保護的作用。高壓配電柜用作(zuo)電(dian)壓(ya)(ya)(ya)等級在3.6 kV~550 kV的電(dian)氣產(chan)品(pin)作(zuo)為高(gao)壓(ya)(ya)(ya)隔離開關，有(you)接(jie)地開關，高(gao)壓(ya)(ya)(ya)斷路器(qi)(qi)(qi)，自動高(gao)壓(ya)(ya)(ya)重合(he)和斷開裝置(zhi)，高(gao)壓(ya)(ya)(ya)操作(zuo)機構(gou)，防爆(bao)高(gao)壓(ya)(ya)(ya)配電(dian)裝置(zhi)和高(gao)壓(ya)(ya)(ya)開關柜(ju)等不同類別。通常，連接(jie)到系(xi)統主母線(xian)的電(dian)容(rong)器(qi)(qi)(qi)柜(ju)用于中央無(wu)功功率補(bu)償，并且(qie)(qie)通常與(yu)輸入柜(ju)并聯安裝（系(xi)統具有(you)PT柜(ju)，應為高(gao)壓(ya)(ya)(ya)系(xi)統，而低壓(ya)(ya)(ya)系(xi)統沒(mei)有(you)PT柜(ju)- PT柜(ju)相當于降低變壓(ya)(ya)(ya)器(qi)(qi)(qi)，只需要低壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)(qi)(qi)，但是電(dian)容(rong)器(qi)(qi)(qi)柜(ju)很(hen)(hen)少用于高(gao)壓(ya)(ya)(ya)系(xi)統中，并且(qie)(qie)高(gao)壓(ya)(ya)(ya)電(dian)容(rong)器(qi)(qi)(qi)很(hen)(hen)難制造，并且(qie)(qie)通常在低壓(ya)(ya)(ya)側(ce)進行集中補(bu)償。
