中電氣設(she)備選擇不當造成的(de)(de)(de)常(chang)(chang)見錯誤：生(sheng)產過程中交流(liu)(liu)(liu)接觸(chu)器(qi)(qi)的(de)(de)(de)體積選擇不當，不同組的(de)(de)(de)插座(zuo)控制電路安裝了相同體積的(de)(de)(de)交流(liu)(liu)(liu)接觸(chu)器(qi)(qi)，三(san)相負載的(de)(de)(de)差異不完(wan)全(quan)考慮過的(de)(de)(de)。在平(ping)衡狀態下，不能在所有正常(chang)(chang)模型中選擇某些組的(de)(de)(de)輸出交流(liu)(liu)(liu)接觸(chu)器(qi)(qi)的(de)(de)(de)電流(liu)(liu)(liu)水平(ping)。基本上，電流(liu)(liu)(liu)水平(ping)是通過一個(ge)步(bu)驟(zou)選擇的(de)(de)(de)，該步(bu)驟(zou)會導(dao)致交流(liu)(liu)(liu)接觸(chu)器(qi)(qi)在高溫天氣下運行(xing)期間(jian)燒斷。

根據電(dian)(dian)氣(qi)設(she)備(bei)的(de)接線規定，接線盒可(ke)安裝在封閉(bi)或(huo)(huo)半(ban)封閉(bi)的(de)金屬外殼(ke)中或(huo)(huo)屏幕上，以形成配電(dian)(dian)室設(she)備(bei)。如果(guo)一切正(zheng)常(chang)，可(ke)以使用手(shou)或(huo)(huo)控制開(kai)關連接或(huo)(huo)斷開(kai)電(dian)(dian)源電(dian)(dian)路。常(chang)見的(de)錯誤或(huo)(huo)異常(chang)取決于家用電(dian)(dian)器的(de)維護，以斷開(kai)電(dian)(dian)路或(huo)(huo)警報(bao)。識(shi)別(bie)儀可(ke)以在信息模(mo)式下顯(xian)示各種(zhong)主要參(can)數，還可(ke)以調(diao)整某些電(dian)(dian)氣(qi)設(she)備(bei)的(de)主要參(can)數，并提醒或(huo)(huo)發出所有正(zheng)常(chang)工(gong)作設(she)置(zhi)的(de)偏差信號。常(chang)用于發電(dian)(dian)，配電(dian)(dian)和變電(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)(zuo)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級在(zai)3.6 kV~550 kV的電(dian)(dian)氣產(chan)品作(zuo)(zuo)為高壓(ya)(ya)(ya)(ya)(ya)隔離開(kai)(kai)關，有接地開(kai)(kai)關，高壓(ya)(ya)(ya)(ya)(ya)斷路器，自動高壓(ya)(ya)(ya)(ya)(ya)重合(he)和斷開(kai)(kai)裝置，高壓(ya)(ya)(ya)(ya)(ya)操作(zuo)(zuo)機構，防(fang)爆高壓(ya)(ya)(ya)(ya)(ya)配電(dian)(dian)裝置和高壓(ya)(ya)(ya)(ya)(ya)開(kai)(kai)關柜(ju)(ju)(ju)(ju)等不同類別。通(tong)常，連(lian)接到(dao)系(xi)統(tong)(tong)(tong)主母線(xian)的電(dian)(dian)容器柜(ju)(ju)(ju)(ju)用于中(zhong)央無功功率補償，并(bing)且(qie)通(tong)常與輸入柜(ju)(ju)(ju)(ju)并(bing)聯安裝（系(xi)統(tong)(tong)(tong)具有PT柜(ju)(ju)(ju)(ju)，應(ying)為高壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)(tong)(tong)，而(er)低壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)(tong)(tong)沒有PT柜(ju)(ju)(ju)(ju)- PT柜(ju)(ju)(ju)(ju)相當(dang)于降低變壓(ya)(ya)(ya)(ya)(ya)器，只需要(yao)低壓(ya)(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)(ya)器，但是電(dian)(dian)容器柜(ju)(ju)(ju)(ju)很少用于高壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)(tong)(tong)中(zhong)，并(bing)且(qie)高壓(ya)(ya)(ya)(ya)(ya)電(dian)(dian)容器很難制造，并(bing)且(qie)通(tong)常在(zai)低壓(ya)(ya)(ya)(ya)(ya)側進行集中(zhong)補償。
