中(zhong)電(dian)氣設備選(xuan)(xuan)擇不當(dang)造成的(de)(de)常見(jian)錯(cuo)誤(wu)：生產過程中(zhong)交(jiao)(jiao)流(liu)接觸(chu)器(qi)(qi)的(de)(de)體積選(xuan)(xuan)擇不當(dang)，不同(tong)組的(de)(de)插座(zuo)控(kong)制電(dian)路安裝了相同(tong)體積的(de)(de)交(jiao)(jiao)流(liu)接觸(chu)器(qi)(qi)，三(san)相負(fu)載的(de)(de)差異不完全考慮過的(de)(de)。在平(ping)(ping)衡(heng)狀(zhuang)態(tai)下，不能在所(suo)有正(zheng)常模型中(zhong)選(xuan)(xuan)擇某些組的(de)(de)輸出交(jiao)(jiao)流(liu)接觸(chu)器(qi)(qi)的(de)(de)電(dian)流(liu)水平(ping)(ping)。基本(ben)上(shang)，電(dian)流(liu)水平(ping)(ping)是(shi)通過一個(ge)步驟(zou)選(xuan)(xuan)擇的(de)(de)，該(gai)步驟(zou)會導致(zhi)交(jiao)(jiao)流(liu)接觸(chu)器(qi)(qi)在高溫天氣下運行期(qi)間燒斷。

根據電(dian)(dian)(dian)氣設備的(de)(de)接(jie)線規定，接(jie)線盒可(ke)安裝在封閉(bi)或半封閉(bi)的(de)(de)金(jin)屬外殼中或屏幕(mu)上，以(yi)形成配電(dian)(dian)(dian)室設備。如(ru)果一切正常，可(ke)以(yi)使用(yong)手或控制(zhi)開關連接(jie)或斷開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的(de)(de)錯誤或異常取決于家用(yong)電(dian)(dian)(dian)器的(de)(de)維護(hu)，以(yi)斷開電(dian)(dian)(dian)路或警報(bao)。識別儀可(ke)以(yi)在信息模式下顯示各種(zhong)主(zhu)(zhu)要(yao)參數(shu)，還(huan)可(ke)以(yi)調(diao)整(zheng)某些電(dian)(dian)(dian)氣設備的(de)(de)主(zhu)(zhu)要(yao)參數(shu)，并提醒或發(fa)出所有正常工作設置的(de)(de)偏差(cha)信號。常用(yong)于發(fa)電(dian)(dian)(dian)，配電(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。高壓配電柜用作電壓(ya)(ya)(ya)(ya)等(deng)級在3.6 kV~550 kV的電氣產品作為高壓(ya)(ya)(ya)(ya)隔離開關，有(you)接地開關，高壓(ya)(ya)(ya)(ya)斷路(lu)器(qi)，自(zi)動高壓(ya)(ya)(ya)(ya)重合和斷開裝(zhuang)置(zhi)，高壓(ya)(ya)(ya)(ya)操作機構，防爆高壓(ya)(ya)(ya)(ya)配電裝(zhuang)置(zhi)和高壓(ya)(ya)(ya)(ya)開關柜(ju)(ju)(ju)等(deng)不同類別。通(tong)常，連接到系(xi)(xi)統(tong)(tong)主母線的電容器(qi)柜(ju)(ju)(ju)用于(yu)中央無功(gong)功(gong)率補(bu)償，并且通(tong)常與輸入柜(ju)(ju)(ju)并聯安裝(zhuang)（系(xi)(xi)統(tong)(tong)具(ju)有(you)PT柜(ju)(ju)(ju)，應為高壓(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)(tong)，而(er)低壓(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)(tong)沒(mei)有(you)PT柜(ju)(ju)(ju)- PT柜(ju)(ju)(ju)相(xiang)當(dang)于(yu)降低變(bian)壓(ya)(ya)(ya)(ya)器(qi)，只需要低壓(ya)(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)(ya)器(qi)，但是電容器(qi)柜(ju)(ju)(ju)很(hen)少(shao)用于(yu)高壓(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)(tong)中，并且高壓(ya)(ya)(ya)(ya)電容器(qi)很(hen)難制(zhi)造，并且通(tong)常在低壓(ya)(ya)(ya)(ya)側進(jin)行集中補(bu)償。
