中電(dian)氣設(she)備(bei)選擇不(bu)(bu)當造成的(de)常(chang)見錯誤：生產(chan)過(guo)程中交(jiao)流接(jie)觸(chu)器(qi)的(de)體(ti)積選擇不(bu)(bu)當，不(bu)(bu)同(tong)組的(de)插座控制電(dian)路(lu)安裝了相同(tong)體(ti)積的(de)交(jiao)流接(jie)觸(chu)器(qi)，三相負載的(de)差異(yi)不(bu)(bu)完(wan)全考慮過(guo)的(de)。在平(ping)衡狀態(tai)下(xia)，不(bu)(bu)能在所有正常(chang)模型中選擇某些組的(de)輸(shu)出交(jiao)流接(jie)觸(chu)器(qi)的(de)電(dian)流水(shui)平(ping)。基本上(shang)，電(dian)流水(shui)平(ping)是(shi)通過(guo)一個步(bu)驟選擇的(de)，該步(bu)驟會導致交(jiao)流接(jie)觸(chu)器(qi)在高溫天氣下(xia)運行(xing)期間燒斷。

根(gen)據(ju)電(dian)(dian)(dian)氣(qi)(qi)設(she)備的(de)(de)接線規定，接線盒可(ke)安裝在(zai)封閉(bi)或(huo)(huo)半封閉(bi)的(de)(de)金屬外殼(ke)中或(huo)(huo)屏(ping)幕上，以(yi)形成配(pei)電(dian)(dian)(dian)室設(she)備。如果一切正常，可(ke)以(yi)使用手或(huo)(huo)控制開關連(lian)接或(huo)(huo)斷開電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)路。常見的(de)(de)錯誤或(huo)(huo)異常取決于家(jia)用電(dian)(dian)(dian)器的(de)(de)維護，以(yi)斷開電(dian)(dian)(dian)路或(huo)(huo)警報(bao)。識別儀可(ke)以(yi)在(zai)信(xin)息(xi)模式下顯示各(ge)種主要(yao)參(can)數，還可(ke)以(yi)調整某些電(dian)(dian)(dian)氣(qi)(qi)設(she)備的(de)(de)主要(yao)參(can)數，并提醒或(huo)(huo)發出所(suo)有正常工作設(she)置的(de)(de)偏差信(xin)號。常用于發電(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)和變電(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。高壓配電柜用作電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級(ji)在(zai)3.6 kV~550 kV的電(dian)(dian)氣產品作為高壓(ya)(ya)(ya)(ya)(ya)隔離開(kai)關(guan)，有接(jie)地開(kai)關(guan)，高壓(ya)(ya)(ya)(ya)(ya)斷路器(qi)，自(zi)動高壓(ya)(ya)(ya)(ya)(ya)重(zhong)合和斷開(kai)裝置，高壓(ya)(ya)(ya)(ya)(ya)操作機構，防爆高壓(ya)(ya)(ya)(ya)(ya)配電(dian)(dian)裝置和高壓(ya)(ya)(ya)(ya)(ya)開(kai)關(guan)柜(ju)等不同類別(bie)。通(tong)常，連接(jie)到系統主母線的電(dian)(dian)容(rong)器(qi)柜(ju)用于(yu)中(zhong)央無功功率補償，并且通(tong)常與輸入柜(ju)并聯(lian)安裝（系統具有PT柜(ju)，應為高壓(ya)(ya)(ya)(ya)(ya)系統，而低(di)(di)壓(ya)(ya)(ya)(ya)(ya)系統沒有PT柜(ju)- PT柜(ju)相當于(yu)降低(di)(di)變壓(ya)(ya)(ya)(ya)(ya)器(qi)，只需要低(di)(di)壓(ya)(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)(ya)器(qi)，但(dan)是電(dian)(dian)容(rong)器(qi)柜(ju)很少用于(yu)高壓(ya)(ya)(ya)(ya)(ya)系統中(zhong)，并且高壓(ya)(ya)(ya)(ya)(ya)電(dian)(dian)容(rong)器(qi)很難制造，并且通(tong)常在(zai)低(di)(di)壓(ya)(ya)(ya)(ya)(ya)側進行集中(zhong)補償。
