中電(dian)氣設備選擇(ze)不(bu)(bu)當造成的(de)常(chang)見錯(cuo)誤：生產過程中交(jiao)(jiao)流(liu)(liu)接觸器(qi)的(de)體積選擇(ze)不(bu)(bu)當，不(bu)(bu)同組(zu)的(de)插座(zuo)控制電(dian)路安裝(zhuang)了相同體積的(de)交(jiao)(jiao)流(liu)(liu)接觸器(qi)，三相負載的(de)差異不(bu)(bu)完全(quan)考慮過的(de)。在平衡狀態下，不(bu)(bu)能在所有(you)正(zheng)常(chang)模型中選擇(ze)某些組(zu)的(de)輸出交(jiao)(jiao)流(liu)(liu)接觸器(qi)的(de)電(dian)流(liu)(liu)水平。基本上，電(dian)流(liu)(liu)水平是通過一個(ge)步驟(zou)(zou)選擇(ze)的(de)，該步驟(zou)(zou)會(hui)導(dao)致(zhi)交(jiao)(jiao)流(liu)(liu)接觸器(qi)在高溫天氣下運行期間燒斷。

根據電(dian)(dian)(dian)(dian)(dian)氣設(she)備的接線規定，接線盒(he)可安裝在(zai)封(feng)閉或(huo)半封(feng)閉的金屬外(wai)殼中或(huo)屏幕上，以形成(cheng)配電(dian)(dian)(dian)(dian)(dian)室設(she)備。如(ru)果一切正常，可以使用(yong)手或(huo)控(kong)制開關連接或(huo)斷(duan)開電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)路(lu)。常見的錯誤或(huo)異常取決于家用(yong)電(dian)(dian)(dian)(dian)(dian)器的維(wei)護，以斷(duan)開電(dian)(dian)(dian)(dian)(dian)路(lu)或(huo)警報(bao)。識別(bie)儀可以在(zai)信息模式下顯示各(ge)種(zhong)主要參數(shu)(shu)，還可以調整某些電(dian)(dian)(dian)(dian)(dian)氣設(she)備的主要參數(shu)(shu)，并提醒或(huo)發出所(suo)有(you)正常工作(zuo)設(she)置(zhi)的偏差信號。常用(yong)于發電(dian)(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)(dian)和變電(dian)(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)(zuo)電(dian)壓(ya)等級在(zai)3.6 kV~550 kV的(de)電(dian)氣產品(pin)作(zuo)(zuo)為高(gao)(gao)壓(ya)隔(ge)離開(kai)關，有(you)接(jie)地開(kai)關，高(gao)(gao)壓(ya)斷路器(qi)，自動高(gao)(gao)壓(ya)重(zhong)合和斷開(kai)裝置，高(gao)(gao)壓(ya)操作(zuo)(zuo)機構(gou)，防爆高(gao)(gao)壓(ya)配(pei)電(dian)裝置和高(gao)(gao)壓(ya)開(kai)關柜(ju)等不同(tong)類別。通常，連接(jie)到(dao)系統(tong)(tong)主(zhu)母(mu)線的(de)電(dian)容器(qi)柜(ju)用于(yu)(yu)中央無功功率補償，并且通常與輸入柜(ju)并聯安裝（系統(tong)(tong)具有(you)PT柜(ju)，應(ying)為高(gao)(gao)壓(ya)系統(tong)(tong)，而低(di)壓(ya)系統(tong)(tong)沒(mei)有(you)PT柜(ju)- PT柜(ju)相當(dang)于(yu)(yu)降低(di)變壓(ya)器(qi)，只需要(yao)低(di)壓(ya)變壓(ya)器(qi)，但是電(dian)容器(qi)柜(ju)很少用于(yu)(yu)高(gao)(gao)壓(ya)系統(tong)(tong)中，并且高(gao)(gao)壓(ya)電(dian)容器(qi)很難制造(zao)，并且通常在(zai)低(di)壓(ya)側進行(xing)集中補償。
