中電(dian)(dian)氣(qi)設備選擇(ze)(ze)不當造(zao)成的常見錯(cuo)誤：生產過(guo)程(cheng)中交(jiao)流接(jie)觸(chu)(chu)器的體積選擇(ze)(ze)不當，不同(tong)(tong)組(zu)的插座控制電(dian)(dian)路(lu)安裝(zhuang)了相同(tong)(tong)體積的交(jiao)流接(jie)觸(chu)(chu)器，三相負(fu)載的差異不完全考慮(lv)過(guo)的。在平(ping)衡狀態(tai)下，不能在所有正(zheng)常模型中選擇(ze)(ze)某些組(zu)的輸(shu)出交(jiao)流接(jie)觸(chu)(chu)器的電(dian)(dian)流水平(ping)。基本上，電(dian)(dian)流水平(ping)是通過(guo)一個步(bu)驟選擇(ze)(ze)的，該步(bu)驟會(hui)導致交(jiao)流接(jie)觸(chu)(chu)器在高溫天氣(qi)下運行期間燒斷。

根據(ju)電(dian)(dian)(dian)氣設(she)備(bei)(bei)的(de)(de)(de)接線(xian)規(gui)定(ding)，接線(xian)盒可(ke)(ke)(ke)安裝在(zai)封(feng)閉(bi)或(huo)(huo)(huo)半(ban)封(feng)閉(bi)的(de)(de)(de)金屬外殼中或(huo)(huo)(huo)屏幕上，以形成配電(dian)(dian)(dian)室設(she)備(bei)(bei)。如果一切(qie)正(zheng)常，可(ke)(ke)(ke)以使用手或(huo)(huo)(huo)控(kong)制開(kai)(kai)關連接或(huo)(huo)(huo)斷(duan)開(kai)(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見(jian)的(de)(de)(de)錯誤(wu)或(huo)(huo)(huo)異常取決(jue)于家用電(dian)(dian)(dian)器的(de)(de)(de)維護，以斷(duan)開(kai)(kai)電(dian)(dian)(dian)路或(huo)(huo)(huo)警(jing)報。識別(bie)儀可(ke)(ke)(ke)以在(zai)信息模(mo)式下顯(xian)示各種主要參數(shu)，還可(ke)(ke)(ke)以調整某(mou)些電(dian)(dian)(dian)氣設(she)備(bei)(bei)的(de)(de)(de)主要參數(shu)，并(bing)提(ti)醒或(huo)(huo)(huo)發(fa)出所有正(zheng)常工作(zuo)設(she)置(zhi)的(de)(de)(de)偏(pian)差信號。常用于發(fa)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(yong)(yong)作電(dian)(dian)(dian)壓(ya)等級在(zai)3.6 kV~550 kV的(de)電(dian)(dian)(dian)氣產(chan)品作為高(gao)(gao)壓(ya)隔(ge)離(li)開(kai)關，有(you)接地開(kai)關，高(gao)(gao)壓(ya)斷(duan)路(lu)器(qi)，自動高(gao)(gao)壓(ya)重合(he)和斷(duan)開(kai)裝置(zhi)(zhi)，高(gao)(gao)壓(ya)操作機構(gou)，防(fang)爆高(gao)(gao)壓(ya)配(pei)電(dian)(dian)(dian)裝置(zhi)(zhi)和高(gao)(gao)壓(ya)開(kai)關柜(ju)等不同類(lei)別。通常，連(lian)接到系(xi)統(tong)主(zhu)母線的(de)電(dian)(dian)(dian)容器(qi)柜(ju)用(yong)(yong)于中(zhong)央無(wu)功功率(lv)補償，并且通常與(yu)輸入柜(ju)并聯安裝（系(xi)統(tong)具(ju)有(you)PT柜(ju)，應(ying)為高(gao)(gao)壓(ya)系(xi)統(tong)，而低(di)(di)(di)壓(ya)系(xi)統(tong)沒有(you)PT柜(ju)- PT柜(ju)相當于降低(di)(di)(di)變壓(ya)器(qi)，只需要低(di)(di)(di)壓(ya)變壓(ya)器(qi)，但是(shi)電(dian)(dian)(dian)容器(qi)柜(ju)很(hen)少用(yong)(yong)于高(gao)(gao)壓(ya)系(xi)統(tong)中(zhong)，并且高(gao)(gao)壓(ya)電(dian)(dian)(dian)容器(qi)很(hen)難制(zhi)造，并且通常在(zai)低(di)(di)(di)壓(ya)側進(jin)行集中(zhong)補償。
