中電(dian)氣設備選(xuan)(xuan)擇不當造成的(de)常(chang)見錯(cuo)誤(wu)：生產過程中交(jiao)(jiao)流接(jie)(jie)觸(chu)器(qi)的(de)體積選(xuan)(xuan)擇不當，不同組的(de)插座控制電(dian)路安(an)裝了(le)相同體積的(de)交(jiao)(jiao)流接(jie)(jie)觸(chu)器(qi)，三相負載的(de)差異不完(wan)全考慮過的(de)。在(zai)平衡狀態下，不能在(zai)所(suo)有正(zheng)常(chang)模(mo)型中選(xuan)(xuan)擇某些組的(de)輸(shu)出交(jiao)(jiao)流接(jie)(jie)觸(chu)器(qi)的(de)電(dian)流水(shui)(shui)平。基(ji)本上，電(dian)流水(shui)(shui)平是(shi)通(tong)過一個步驟(zou)選(xuan)(xuan)擇的(de)，該(gai)步驟(zou)會導致交(jiao)(jiao)流接(jie)(jie)觸(chu)器(qi)在(zai)高溫天氣下運行(xing)期(qi)間燒斷。

根據電(dian)(dian)(dian)氣設(she)備(bei)的接(jie)線規定，接(jie)線盒可(ke)安裝在(zai)封閉(bi)或半(ban)封閉(bi)的金(jin)屬外殼(ke)中或屏幕上，以(yi)(yi)形成配電(dian)(dian)(dian)室(shi)設(she)備(bei)。如果(guo)一(yi)切(qie)正常(chang)，可(ke)以(yi)(yi)使用手或控制開(kai)(kai)關(guan)連(lian)接(jie)或斷開(kai)(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)。常(chang)見的錯誤或異常(chang)取決于家(jia)用電(dian)(dian)(dian)器的維護，以(yi)(yi)斷開(kai)(kai)電(dian)(dian)(dian)路(lu)或警報。識(shi)別儀可(ke)以(yi)(yi)在(zai)信息模式下顯(xian)示各種主要(yao)參數，還可(ke)以(yi)(yi)調整某些電(dian)(dian)(dian)氣設(she)備(bei)的主要(yao)參數，并提(ti)醒或發出所有正常(chang)工作設(she)置的偏(pian)差信號。常(chang)用于發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(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。高壓配電柜用作(zuo)電(dian)壓(ya)(ya)(ya)等(deng)(deng)級在3.6 kV~550 kV的電(dian)氣產品作(zuo)為高壓(ya)(ya)(ya)隔(ge)離開(kai)關，有接(jie)地(di)開(kai)關，高壓(ya)(ya)(ya)斷路器(qi)(qi)(qi)，自動高壓(ya)(ya)(ya)重合(he)和斷開(kai)裝(zhuang)置(zhi)，高壓(ya)(ya)(ya)操(cao)作(zuo)機構，防爆高壓(ya)(ya)(ya)配電(dian)裝(zhuang)置(zhi)和高壓(ya)(ya)(ya)開(kai)關柜(ju)(ju)(ju)等(deng)(deng)不同類別。通常，連(lian)接(jie)到系(xi)(xi)統(tong)主母線的電(dian)容(rong)器(qi)(qi)(qi)柜(ju)(ju)(ju)用于(yu)中(zhong)央無功功率補(bu)償，并(bing)(bing)且通常與輸入(ru)柜(ju)(ju)(ju)并(bing)(bing)聯安(an)裝(zhuang)（系(xi)(xi)統(tong)具有PT柜(ju)(ju)(ju)，應為高壓(ya)(ya)(ya)系(xi)(xi)統(tong)，而低(di)(di)壓(ya)(ya)(ya)系(xi)(xi)統(tong)沒(mei)有PT柜(ju)(ju)(ju)- PT柜(ju)(ju)(ju)相當于(yu)降低(di)(di)變(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)，只需要(yao)低(di)(di)壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)，但是電(dian)容(rong)器(qi)(qi)(qi)柜(ju)(ju)(ju)很少(shao)用于(yu)高壓(ya)(ya)(ya)系(xi)(xi)統(tong)中(zhong)，并(bing)(bing)且高壓(ya)(ya)(ya)電(dian)容(rong)器(qi)(qi)(qi)很難(nan)制造，并(bing)(bing)且通常在低(di)(di)壓(ya)(ya)(ya)側進(jin)行集(ji)中(zhong)補(bu)償。
