中電氣設(she)備選(xuan)(xuan)擇不(bu)當造成的(de)(de)(de)(de)常見錯誤(wu)：生(sheng)產過程中交流(liu)接(jie)觸(chu)器(qi)的(de)(de)(de)(de)體(ti)積(ji)選(xuan)(xuan)擇不(bu)當，不(bu)同組的(de)(de)(de)(de)插座控制電路安裝(zhuang)了相同體(ti)積(ji)的(de)(de)(de)(de)交流(liu)接(jie)觸(chu)器(qi)，三相負載的(de)(de)(de)(de)差異不(bu)完全(quan)考慮過的(de)(de)(de)(de)。在平(ping)衡狀(zhuang)態下，不(bu)能(neng)在所有正(zheng)常模型中選(xuan)(xuan)擇某些組的(de)(de)(de)(de)輸出(chu)交流(liu)接(jie)觸(chu)器(qi)的(de)(de)(de)(de)電流(liu)水平(ping)。基本上，電流(liu)水平(ping)是通過一個步驟選(xuan)(xuan)擇的(de)(de)(de)(de)，該步驟會(hui)導致交流(liu)接(jie)觸(chu)器(qi)在高溫天氣下運行(xing)期間燒斷(duan)。

根據電(dian)(dian)(dian)氣(qi)設備的(de)接線規定(ding)，接線盒可安裝在封閉或(huo)半封閉的(de)金屬外殼中或(huo)屏幕上(shang)，以形成(cheng)配(pei)電(dian)(dian)(dian)室設備。如果(guo)一(yi)切正(zheng)常(chang)，可以使用手(shou)或(huo)控制開(kai)關(guan)連接或(huo)斷開(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常(chang)見的(de)錯誤(wu)或(huo)異常(chang)取(qu)決于(yu)家用電(dian)(dian)(dian)器(qi)的(de)維護，以斷開(kai)電(dian)(dian)(dian)路或(huo)警報。識(shi)別儀可以在信息(xi)模式下顯示各種(zhong)主(zhu)要(yao)參(can)數，還可以調整某些電(dian)(dian)(dian)氣(qi)設備的(de)主(zhu)要(yao)參(can)數，并提(ti)醒或(huo)發(fa)出所有正(zheng)常(chang)工(gong)作設置(zhi)的(de)偏差信號(hao)。常(chang)用于(yu)發(fa)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(yong)作(zuo)(zuo)電(dian)(dian)(dian)壓等(deng)級在3.6 kV~550 kV的電(dian)(dian)(dian)氣(qi)產品(pin)作(zuo)(zuo)為(wei)(wei)高(gao)(gao)壓隔離(li)開關(guan)，有接地開關(guan)，高(gao)(gao)壓斷(duan)路器(qi)(qi)，自動高(gao)(gao)壓重(zhong)合和斷(duan)開裝置，高(gao)(gao)壓操(cao)作(zuo)(zuo)機構，防爆高(gao)(gao)壓配電(dian)(dian)(dian)裝置和高(gao)(gao)壓開關(guan)柜(ju)(ju)等(deng)不同類別。通(tong)(tong)常，連接到系統(tong)(tong)主母(mu)線的電(dian)(dian)(dian)容(rong)器(qi)(qi)柜(ju)(ju)用(yong)于中(zhong)央無功功率補償，并(bing)且(qie)(qie)通(tong)(tong)常與輸入柜(ju)(ju)并(bing)聯安裝（系統(tong)(tong)具有PT柜(ju)(ju)，應為(wei)(wei)高(gao)(gao)壓系統(tong)(tong)，而低壓系統(tong)(tong)沒有PT柜(ju)(ju)- PT柜(ju)(ju)相當(dang)于降(jiang)低變(bian)壓器(qi)(qi)，只需要低壓變(bian)壓器(qi)(qi)，但是電(dian)(dian)(dian)容(rong)器(qi)(qi)柜(ju)(ju)很少用(yong)于高(gao)(gao)壓系統(tong)(tong)中(zhong)，并(bing)且(qie)(qie)高(gao)(gao)壓電(dian)(dian)(dian)容(rong)器(qi)(qi)很難制造，并(bing)且(qie)(qie)通(tong)(tong)常在低壓側進行集中(zhong)補償。
