中電氣設備選(xuan)擇不當造(zao)成的(de)(de)常見錯誤：生產過程中交(jiao)流(liu)接(jie)觸(chu)(chu)器(qi)的(de)(de)體(ti)積(ji)選(xuan)擇不當，不同(tong)組的(de)(de)插座控(kong)制電路(lu)安(an)裝了相同(tong)體(ti)積(ji)的(de)(de)交(jiao)流(liu)接(jie)觸(chu)(chu)器(qi)，三相負載的(de)(de)差異(yi)不完全考慮過的(de)(de)。在平(ping)衡狀(zhuang)態(tai)下，不能在所有正常模型(xing)中選(xuan)擇某些組的(de)(de)輸(shu)出交(jiao)流(liu)接(jie)觸(chu)(chu)器(qi)的(de)(de)電流(liu)水(shui)平(ping)。基本上，電流(liu)水(shui)平(ping)是通(tong)過一個(ge)步驟選(xuan)擇的(de)(de)，該(gai)步驟會導致交(jiao)流(liu)接(jie)觸(chu)(chu)器(qi)在高溫天氣下運行期(qi)間燒斷。

根據電(dian)(dian)(dian)氣設備的接線(xian)規定(ding)，接線(xian)盒可(ke)安裝在封閉(bi)或(huo)(huo)(huo)半(ban)封閉(bi)的金(jin)屬外(wai)殼中(zhong)或(huo)(huo)(huo)屏幕上，以(yi)(yi)形成配(pei)電(dian)(dian)(dian)室設備。如果一切正常(chang)(chang)，可(ke)以(yi)(yi)使用(yong)(yong)手(shou)或(huo)(huo)(huo)控制(zhi)開(kai)(kai)關連接或(huo)(huo)(huo)斷開(kai)(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常(chang)(chang)見的錯誤或(huo)(huo)(huo)異常(chang)(chang)取決于家用(yong)(yong)電(dian)(dian)(dian)器的維護，以(yi)(yi)斷開(kai)(kai)電(dian)(dian)(dian)路或(huo)(huo)(huo)警報。識別儀可(ke)以(yi)(yi)在信息(xi)模式下顯示各種(zhong)主要參數(shu)，還(huan)可(ke)以(yi)(yi)調整某些電(dian)(dian)(dian)氣設備的主要參數(shu)，并提醒或(huo)(huo)(huo)發出(chu)所有(you)正常(chang)(chang)工作(zuo)設置的偏差信號。常(chang)(chang)用(yong)(yong)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(yong)作電(dian)(dian)(dian)壓(ya)(ya)等級(ji)在3.6 kV~550 kV的電(dian)(dian)(dian)氣產(chan)品作為高(gao)壓(ya)(ya)隔(ge)離開關，有接(jie)(jie)地(di)開關，高(gao)壓(ya)(ya)斷(duan)路器(qi)，自(zi)動高(gao)壓(ya)(ya)重(zhong)合和(he)斷(duan)開裝(zhuang)(zhuang)置(zhi)，高(gao)壓(ya)(ya)操作機構，防爆高(gao)壓(ya)(ya)配電(dian)(dian)(dian)裝(zhuang)(zhuang)置(zhi)和(he)高(gao)壓(ya)(ya)開關柜(ju)(ju)(ju)等不同(tong)類別。通(tong)(tong)常，連(lian)接(jie)(jie)到系(xi)統主(zhu)母線的電(dian)(dian)(dian)容器(qi)柜(ju)(ju)(ju)用(yong)于中(zhong)央無功功率補(bu)償，并且通(tong)(tong)常與輸入柜(ju)(ju)(ju)并聯(lian)安裝(zhuang)(zhuang)（系(xi)統具(ju)有PT柜(ju)(ju)(ju)，應為高(gao)壓(ya)(ya)系(xi)統，而低壓(ya)(ya)系(xi)統沒(mei)有PT柜(ju)(ju)(ju)- PT柜(ju)(ju)(ju)相當于降低變壓(ya)(ya)器(qi)，只(zhi)需(xu)要(yao)低壓(ya)(ya)變壓(ya)(ya)器(qi)，但(dan)是(shi)電(dian)(dian)(dian)容器(qi)柜(ju)(ju)(ju)很(hen)少用(yong)于高(gao)壓(ya)(ya)系(xi)統中(zhong)，并且高(gao)壓(ya)(ya)電(dian)(dian)(dian)容器(qi)很(hen)難制造，并且通(tong)(tong)常在低壓(ya)(ya)側進行(xing)集中(zhong)補(bu)償。
