中電(dian)氣設備選擇(ze)不當(dang)(dang)造(zao)成的(de)(de)(de)(de)常見錯(cuo)誤：生產過程中交流(liu)(liu)接(jie)觸器(qi)的(de)(de)(de)(de)體積選擇(ze)不當(dang)(dang)，不同組(zu)(zu)的(de)(de)(de)(de)插座控制電(dian)路安裝(zhuang)了(le)相同體積的(de)(de)(de)(de)交流(liu)(liu)接(jie)觸器(qi)，三相負載的(de)(de)(de)(de)差異不完全(quan)考慮過的(de)(de)(de)(de)。在(zai)平衡(heng)狀態下，不能在(zai)所有正常模型(xing)中選擇(ze)某些(xie)組(zu)(zu)的(de)(de)(de)(de)輸出交流(liu)(liu)接(jie)觸器(qi)的(de)(de)(de)(de)電(dian)流(liu)(liu)水平。基本(ben)上，電(dian)流(liu)(liu)水平是通過一個步驟選擇(ze)的(de)(de)(de)(de)，該步驟會(hui)導致交流(liu)(liu)接(jie)觸器(qi)在(zai)高溫(wen)天(tian)氣下運行期間燒斷。

根據電(dian)(dian)(dian)(dian)氣(qi)(qi)設(she)備的(de)(de)(de)接(jie)線規定，接(jie)線盒可(ke)安裝在封閉(bi)或(huo)(huo)半封閉(bi)的(de)(de)(de)金屬外殼(ke)中或(huo)(huo)屏(ping)幕上，以(yi)(yi)形成配電(dian)(dian)(dian)(dian)室設(she)備。如果一切正常，可(ke)以(yi)(yi)使用手或(huo)(huo)控制(zhi)開關連(lian)接(jie)或(huo)(huo)斷(duan)開電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的(de)(de)(de)錯誤(wu)或(huo)(huo)異常取(qu)決于家用電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)維護，以(yi)(yi)斷(duan)開電(dian)(dian)(dian)(dian)路或(huo)(huo)警報。識別(bie)儀可(ke)以(yi)(yi)在信息模式下顯示各種主要(yao)參數，還(huan)可(ke)以(yi)(yi)調整某些電(dian)(dian)(dian)(dian)氣(qi)(qi)設(she)備的(de)(de)(de)主要(yao)參數，并提醒或(huo)(huo)發出(chu)所有正常工作(zuo)設(she)置的(de)(de)(de)偏差信號。常用于發電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和(he)變電(dian)(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)等級在3.6 kV~550 kV的電(dian)氣產品(pin)作(zuo)為高(gao)(gao)壓(ya)(ya)(ya)隔(ge)離開關(guan)，有(you)接地開關(guan)，高(gao)(gao)壓(ya)(ya)(ya)斷(duan)路器(qi)，自動高(gao)(gao)壓(ya)(ya)(ya)重合和斷(duan)開裝置，高(gao)(gao)壓(ya)(ya)(ya)操作(zuo)機構，防(fang)爆高(gao)(gao)壓(ya)(ya)(ya)配電(dian)裝置和高(gao)(gao)壓(ya)(ya)(ya)開關(guan)柜(ju)(ju)(ju)等不同類別。通常，連(lian)接到系統(tong)(tong)主母線的電(dian)容器(qi)柜(ju)(ju)(ju)用于中(zhong)央(yang)無功(gong)功(gong)率補(bu)償，并(bing)且(qie)通常與輸入柜(ju)(ju)(ju)并(bing)聯安裝（系統(tong)(tong)具(ju)有(you)PT柜(ju)(ju)(ju)，應(ying)為高(gao)(gao)壓(ya)(ya)(ya)系統(tong)(tong)，而低(di)壓(ya)(ya)(ya)系統(tong)(tong)沒有(you)PT柜(ju)(ju)(ju)- PT柜(ju)(ju)(ju)相(xiang)當于降低(di)變(bian)壓(ya)(ya)(ya)器(qi)，只需要(yao)低(di)壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器(qi)，但是(shi)電(dian)容器(qi)柜(ju)(ju)(ju)很少用于高(gao)(gao)壓(ya)(ya)(ya)系統(tong)(tong)中(zhong)，并(bing)且(qie)高(gao)(gao)壓(ya)(ya)(ya)電(dian)容器(qi)很難制造，并(bing)且(qie)通常在低(di)壓(ya)(ya)(ya)側(ce)進行集中(zhong)補(bu)償。
