中(zhong)電(dian)(dian)氣設備選擇(ze)不當造成的(de)常見錯誤：生(sheng)產過(guo)程中(zhong)交流(liu)(liu)(liu)接觸器(qi)的(de)體積選擇(ze)不當，不同組(zu)的(de)插座控制電(dian)(dian)路安裝了相同體積的(de)交流(liu)(liu)(liu)接觸器(qi)，三相負(fu)載的(de)差異不完全考慮(lv)過(guo)的(de)。在平(ping)(ping)衡狀態下，不能在所有(you)正常模型中(zhong)選擇(ze)某些組(zu)的(de)輸出交流(liu)(liu)(liu)接觸器(qi)的(de)電(dian)(dian)流(liu)(liu)(liu)水(shui)平(ping)(ping)。基本上，電(dian)(dian)流(liu)(liu)(liu)水(shui)平(ping)(ping)是通過(guo)一個步驟選擇(ze)的(de)，該(gai)步驟會導致交流(liu)(liu)(liu)接觸器(qi)在高溫天氣下運(yun)行期間(jian)燒斷。

根據電(dian)(dian)(dian)(dian)氣設備的(de)接線(xian)規定，接線(xian)盒可(ke)安裝在封閉或(huo)半封閉的(de)金屬外殼中或(huo)屏幕上，以(yi)形成(cheng)配(pei)電(dian)(dian)(dian)(dian)室設備。如果(guo)一切正常，可(ke)以(yi)使用(yong)手或(huo)控制開(kai)關連接或(huo)斷開(kai)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的(de)錯(cuo)誤或(huo)異常取(qu)決于(yu)家(jia)用(yong)電(dian)(dian)(dian)(dian)器的(de)維護(hu)，以(yi)斷開(kai)電(dian)(dian)(dian)(dian)路或(huo)警(jing)報。識別儀可(ke)以(yi)在信息模式下(xia)顯(xian)示各種主要參數，還可(ke)以(yi)調整(zheng)某些電(dian)(dian)(dian)(dian)氣設備的(de)主要參數，并提醒或(huo)發(fa)出所有(you)正常工(gong)作(zuo)設置的(de)偏差(cha)信號。常用(yong)于(yu)發(fa)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(yong)(yong)作電(dian)壓(ya)(ya)等級在3.6 kV~550 kV的電(dian)氣產(chan)品作為高(gao)壓(ya)(ya)隔離開關，有(you)接地開關，高(gao)壓(ya)(ya)斷(duan)路(lu)器(qi)，自動高(gao)壓(ya)(ya)重合和斷(duan)開裝(zhuang)置，高(gao)壓(ya)(ya)操作機構(gou)，防爆高(gao)壓(ya)(ya)配電(dian)裝(zhuang)置和高(gao)壓(ya)(ya)開關柜等不同類別。通(tong)常，連接到系(xi)統主母線的電(dian)容(rong)器(qi)柜用(yong)(yong)于(yu)中(zhong)央無(wu)功(gong)功(gong)率(lv)補償，并且通(tong)常與輸(shu)入柜并聯安裝(zhuang)（系(xi)統具有(you)PT柜，應為高(gao)壓(ya)(ya)系(xi)統，而(er)低壓(ya)(ya)系(xi)統沒(mei)有(you)PT柜- PT柜相當于(yu)降低變壓(ya)(ya)器(qi)，只需要(yao)低壓(ya)(ya)變壓(ya)(ya)器(qi)，但是電(dian)容(rong)器(qi)柜很(hen)少用(yong)(yong)于(yu)高(gao)壓(ya)(ya)系(xi)統中(zhong)，并且高(gao)壓(ya)(ya)電(dian)容(rong)器(qi)很(hen)難制(zhi)造(zao)，并且通(tong)常在低壓(ya)(ya)側進行集(ji)中(zhong)補償。
