中電(dian)氣(qi)設備選(xuan)擇(ze)不(bu)當(dang)造成的常(chang)見錯誤：生產過程中交流接(jie)觸器的體積(ji)選(xuan)擇(ze)不(bu)當(dang)，不(bu)同組的插座控制電(dian)路安裝了相(xiang)同體積(ji)的交流接(jie)觸器，三相(xiang)負載(zai)的差異不(bu)完全考慮過的。在平衡狀態下(xia)，不(bu)能在所有正常(chang)模型中選(xuan)擇(ze)某些組的輸出交流接(jie)觸器的電(dian)流水平。基本(ben)上，電(dian)流水平是通過一個步(bu)驟選(xuan)擇(ze)的，該步(bu)驟會導致交流接(jie)觸器在高溫(wen)天氣(qi)下(xia)運(yun)行(xing)期間燒斷。

根據電(dian)(dian)(dian)氣設(she)(she)備的接(jie)線(xian)規定，接(jie)線(xian)盒可(ke)安裝在封閉(bi)或(huo)半封閉(bi)的金屬外(wai)殼中(zhong)或(huo)屏幕上，以(yi)(yi)形成配電(dian)(dian)(dian)室設(she)(she)備。如果一(yi)切正常，可(ke)以(yi)(yi)使(shi)用(yong)手或(huo)控制開(kai)關連接(jie)或(huo)斷開(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的錯誤或(huo)異常取(qu)決于家用(yong)電(dian)(dian)(dian)器的維護，以(yi)(yi)斷開(kai)電(dian)(dian)(dian)路或(huo)警報。識(shi)別(bie)儀可(ke)以(yi)(yi)在信息模(mo)式下顯示各種主(zhu)要參數，還可(ke)以(yi)(yi)調整某些(xie)電(dian)(dian)(dian)氣設(she)(she)備的主(zhu)要參數，并提醒(xing)或(huo)發出所(suo)有正常工作設(she)(she)置的偏(pian)差信號。常用(yong)于發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和(he)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。高壓配電柜用作電壓(ya)(ya)(ya)(ya)等(deng)級在3.6 kV~550 kV的電氣(qi)產品(pin)作為高(gao)壓(ya)(ya)(ya)(ya)隔(ge)離開(kai)關(guan)，有(you)(you)接地開(kai)關(guan)，高(gao)壓(ya)(ya)(ya)(ya)斷(duan)路器(qi)，自動高(gao)壓(ya)(ya)(ya)(ya)重合(he)和斷(duan)開(kai)裝置，高(gao)壓(ya)(ya)(ya)(ya)操(cao)作機(ji)構(gou)，防爆高(gao)壓(ya)(ya)(ya)(ya)配電裝置和高(gao)壓(ya)(ya)(ya)(ya)開(kai)關(guan)柜(ju)等(deng)不同類別。通常，連接到(dao)系統(tong)主母(mu)線的電容(rong)器(qi)柜(ju)用于中(zhong)央無功(gong)(gong)功(gong)(gong)率補償，并(bing)且(qie)通常與輸入(ru)柜(ju)并(bing)聯安裝（系統(tong)具(ju)有(you)(you)PT柜(ju)，應為高(gao)壓(ya)(ya)(ya)(ya)系統(tong)，而低(di)(di)壓(ya)(ya)(ya)(ya)系統(tong)沒有(you)(you)PT柜(ju)- PT柜(ju)相當于降(jiang)低(di)(di)變壓(ya)(ya)(ya)(ya)器(qi)，只需要低(di)(di)壓(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)器(qi)，但(dan)是(shi)電容(rong)器(qi)柜(ju)很少用于高(gao)壓(ya)(ya)(ya)(ya)系統(tong)中(zhong)，并(bing)且(qie)高(gao)壓(ya)(ya)(ya)(ya)電容(rong)器(qi)很難(nan)制造，并(bing)且(qie)通常在低(di)(di)壓(ya)(ya)(ya)(ya)側進行集中(zhong)補償。
