中電氣設(she)備選(xuan)擇不(bu)(bu)當造(zao)成的(de)常見(jian)錯誤：生產過程(cheng)中交流接(jie)觸(chu)器的(de)體積選(xuan)擇不(bu)(bu)當，不(bu)(bu)同(tong)組的(de)插座(zuo)控制電路安(an)裝了相(xiang)(xiang)同(tong)體積的(de)交流接(jie)觸(chu)器，三相(xiang)(xiang)負載的(de)差異不(bu)(bu)完全考慮過的(de)。在平衡狀(zhuang)態(tai)下，不(bu)(bu)能在所(suo)有(you)正常模(mo)型中選(xuan)擇某些組的(de)輸(shu)出(chu)交流接(jie)觸(chu)器的(de)電流水平。基本上，電流水平是通(tong)過一個步驟(zou)選(xuan)擇的(de)，該步驟(zou)會導致交流接(jie)觸(chu)器在高溫天氣下運行期間燒斷(duan)。

根據(ju)電(dian)(dian)(dian)氣設(she)備(bei)的(de)接(jie)(jie)線(xian)規定，接(jie)(jie)線(xian)盒可安(an)裝(zhuang)在(zai)封閉(bi)(bi)或半封閉(bi)(bi)的(de)金屬外殼中或屏幕上，以形(xing)成配電(dian)(dian)(dian)室設(she)備(bei)。如果一切正常(chang)(chang)，可以使用(yong)手或控制開關連(lian)接(jie)(jie)或斷(duan)開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常(chang)(chang)見的(de)錯(cuo)誤或異常(chang)(chang)取決于(yu)家用(yong)電(dian)(dian)(dian)器(qi)的(de)維(wei)護，以斷(duan)開電(dian)(dian)(dian)路或警報。識別儀可以在(zai)信息模式下(xia)顯示各種主(zhu)要參(can)數，還可以調(diao)整某些電(dian)(dian)(dian)氣設(she)備(bei)的(de)主(zhu)要參(can)數，并提醒或發(fa)出所有正常(chang)(chang)工作設(she)置的(de)偏差信號。常(chang)(chang)用(yong)于(yu)發(fa)電(dian)(dian)(dian)，配電(dian)(dian)(dian)和(he)變電(dian)(dian)(dian)站。

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(yong)作(zuo)(zuo)電(dian)(dian)壓(ya)(ya)等級(ji)在3.6 kV~550 kV的(de)電(dian)(dian)氣產品作(zuo)(zuo)為高壓(ya)(ya)隔離開(kai)(kai)關(guan)，有(you)(you)接地開(kai)(kai)關(guan)，高壓(ya)(ya)斷路器(qi)，自動高壓(ya)(ya)重合和斷開(kai)(kai)裝置，高壓(ya)(ya)操作(zuo)(zuo)機構，防爆高壓(ya)(ya)配(pei)電(dian)(dian)裝置和高壓(ya)(ya)開(kai)(kai)關(guan)柜(ju)(ju)等不同類(lei)別。通(tong)常(chang)，連接到系(xi)(xi)(xi)統(tong)(tong)主母線(xian)的(de)電(dian)(dian)容器(qi)柜(ju)(ju)用(yong)于中央無功功率補償，并且通(tong)常(chang)與輸入柜(ju)(ju)并聯安裝（系(xi)(xi)(xi)統(tong)(tong)具有(you)(you)PT柜(ju)(ju)，應為高壓(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)，而低壓(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)沒有(you)(you)PT柜(ju)(ju)- PT柜(ju)(ju)相當于降(jiang)低變壓(ya)(ya)器(qi)，只需要低壓(ya)(ya)變壓(ya)(ya)器(qi)，但(dan)是電(dian)(dian)容器(qi)柜(ju)(ju)很少用(yong)于高壓(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)中，并且高壓(ya)(ya)電(dian)(dian)容器(qi)很難制造，并且通(tong)常(chang)在低壓(ya)(ya)側進行集(ji)中補償。
