中電(dian)(dian)氣設(she)備選(xuan)擇(ze)不當造(zao)成的常(chang)見錯(cuo)誤：生產過程中交(jiao)流(liu)接觸(chu)器的體積(ji)(ji)選(xuan)擇(ze)不當，不同(tong)組的插座控制(zhi)電(dian)(dian)路安裝了相同(tong)體積(ji)(ji)的交(jiao)流(liu)接觸(chu)器，三相負(fu)載的差異不完全考慮過的。在平衡(heng)狀態下，不能在所(suo)有正常(chang)模型中選(xuan)擇(ze)某些組的輸出交(jiao)流(liu)接觸(chu)器的電(dian)(dian)流(liu)水平。基本上，電(dian)(dian)流(liu)水平是通過一個步驟選(xuan)擇(ze)的，該步驟會導致交(jiao)流(liu)接觸(chu)器在高溫天氣下運行期間燒斷。

根(gen)據電(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)接線規定，接線盒可安裝(zhuang)在封(feng)閉或(huo)(huo)半封(feng)閉的(de)金屬外殼中或(huo)(huo)屏幕上，以形成(cheng)配電(dian)(dian)(dian)(dian)室設(she)備(bei)。如果(guo)一切正常(chang)，可以使用手(shou)或(huo)(huo)控制開關連接或(huo)(huo)斷開電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路(lu)。常(chang)見的(de)錯誤或(huo)(huo)異常(chang)取決于家(jia)用電(dian)(dian)(dian)(dian)器的(de)維護，以斷開電(dian)(dian)(dian)(dian)路(lu)或(huo)(huo)警報。識別(bie)儀可以在信息(xi)模式(shi)下顯示各(ge)種主要參(can)(can)數，還可以調(diao)整(zheng)某(mou)些電(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)主要參(can)(can)數，并提醒或(huo)(huo)發出所有(you)正常(chang)工作設(she)置(zhi)的(de)偏差(cha)信號。常(chang)用于發電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和變電(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(yong)作電(dian)(dian)壓(ya)(ya)(ya)等(deng)級在(zai)3.6 kV~550 kV的(de)電(dian)(dian)氣產品作為高(gao)壓(ya)(ya)(ya)隔離開關，有接地開關，高(gao)壓(ya)(ya)(ya)斷路器(qi)，自動高(gao)壓(ya)(ya)(ya)重合和(he)斷開裝(zhuang)置，高(gao)壓(ya)(ya)(ya)操作機(ji)構，防爆高(gao)壓(ya)(ya)(ya)配電(dian)(dian)裝(zhuang)置和(he)高(gao)壓(ya)(ya)(ya)開關柜(ju)(ju)等(deng)不(bu)同類別。通常，連接到系統(tong)(tong)主母線的(de)電(dian)(dian)容器(qi)柜(ju)(ju)用(yong)于中(zhong)央無功功率補償，并且通常與輸入柜(ju)(ju)并聯安裝(zhuang)（系統(tong)(tong)具有PT柜(ju)(ju)，應(ying)為高(gao)壓(ya)(ya)(ya)系統(tong)(tong)，而低壓(ya)(ya)(ya)系統(tong)(tong)沒有PT柜(ju)(ju)- PT柜(ju)(ju)相當于降(jiang)低變壓(ya)(ya)(ya)器(qi)，只(zhi)需(xu)要低壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器(qi)，但是電(dian)(dian)容器(qi)柜(ju)(ju)很(hen)少用(yong)于高(gao)壓(ya)(ya)(ya)系統(tong)(tong)中(zhong)，并且高(gao)壓(ya)(ya)(ya)電(dian)(dian)容器(qi)很(hen)難制造(zao)，并且通常在(zai)低壓(ya)(ya)(ya)側進行集中(zhong)補償。
