中(zhong)(zhong)電(dian)氣設(she)備選擇(ze)不當(dang)造成的(de)(de)常見錯誤：生產過(guo)程中(zhong)(zhong)交流(liu)接(jie)觸(chu)器的(de)(de)體積選擇(ze)不當(dang)，不同(tong)組(zu)的(de)(de)插座控制電(dian)路安(an)裝了相同(tong)體積的(de)(de)交流(liu)接(jie)觸(chu)器，三相負載的(de)(de)差異(yi)不完全考(kao)慮過(guo)的(de)(de)。在(zai)(zai)平衡狀態下(xia)，不能在(zai)(zai)所有正常模型中(zhong)(zhong)選擇(ze)某些組(zu)的(de)(de)輸出交流(liu)接(jie)觸(chu)器的(de)(de)電(dian)流(liu)水(shui)平。基本上，電(dian)流(liu)水(shui)平是通過(guo)一個步驟選擇(ze)的(de)(de)，該步驟會導致交流(liu)接(jie)觸(chu)器在(zai)(zai)高溫天氣下(xia)運(yun)行(xing)期間燒斷。

根據電(dian)(dian)(dian)氣(qi)設(she)備(bei)的接(jie)(jie)線規(gui)定，接(jie)(jie)線盒可(ke)(ke)安裝在封閉(bi)或半封閉(bi)的金屬外殼中或屏幕(mu)上，以形成配(pei)電(dian)(dian)(dian)室(shi)設(she)備(bei)。如(ru)果一(yi)切正常，可(ke)(ke)以使用手或控制開關連(lian)接(jie)(jie)或斷開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見(jian)的錯(cuo)誤或異(yi)常取決于家用電(dian)(dian)(dian)器的維護，以斷開電(dian)(dian)(dian)路或警報。識別儀可(ke)(ke)以在信息模式下顯(xian)示(shi)各種(zhong)主要(yao)參(can)數，還可(ke)(ke)以調整某些電(dian)(dian)(dian)氣(qi)設(she)備(bei)的主要(yao)參(can)數，并提醒或發出所有正常工作設(she)置的偏差信號。常用于發電(dian)(dian)(dian)，配(pei)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)(dian)(dian)壓(ya)(ya)等級在3.6 kV~550 kV的(de)(de)電(dian)(dian)(dian)氣產品作(zuo)為(wei)高(gao)(gao)壓(ya)(ya)隔離(li)開關(guan)，有(you)(you)接地開關(guan)，高(gao)(gao)壓(ya)(ya)斷(duan)路(lu)器(qi)(qi)，自動(dong)高(gao)(gao)壓(ya)(ya)重合和斷(duan)開裝置(zhi)，高(gao)(gao)壓(ya)(ya)操作(zuo)機構，防(fang)爆高(gao)(gao)壓(ya)(ya)配電(dian)(dian)(dian)裝置(zhi)和高(gao)(gao)壓(ya)(ya)開關(guan)柜等不同類別(bie)。通常，連接到系(xi)(xi)(xi)統主母線的(de)(de)電(dian)(dian)(dian)容(rong)器(qi)(qi)柜用于(yu)中(zhong)央無功(gong)功(gong)率補(bu)償，并且通常與(yu)輸(shu)入柜并聯安裝（系(xi)(xi)(xi)統具(ju)有(you)(you)PT柜，應(ying)為(wei)高(gao)(gao)壓(ya)(ya)系(xi)(xi)(xi)統，而低(di)壓(ya)(ya)系(xi)(xi)(xi)統沒有(you)(you)PT柜- PT柜相當于(yu)降低(di)變壓(ya)(ya)器(qi)(qi)，只需要低(di)壓(ya)(ya)變壓(ya)(ya)器(qi)(qi)，但是電(dian)(dian)(dian)容(rong)器(qi)(qi)柜很少用于(yu)高(gao)(gao)壓(ya)(ya)系(xi)(xi)(xi)統中(zhong)，并且高(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)容(rong)器(qi)(qi)很難制造，并且通常在低(di)壓(ya)(ya)側進行集中(zhong)補(bu)償。
