中電(dian)氣(qi)設備(bei)選(xuan)(xuan)擇不當造成(cheng)的常見(jian)錯誤(wu)：生產過(guo)程中交(jiao)(jiao)流(liu)(liu)接(jie)觸(chu)(chu)器(qi)的體(ti)積(ji)選(xuan)(xuan)擇不當，不同(tong)組(zu)的插(cha)座控(kong)制電(dian)路(lu)安裝了相(xiang)同(tong)體(ti)積(ji)的交(jiao)(jiao)流(liu)(liu)接(jie)觸(chu)(chu)器(qi)，三相(xiang)負載的差異不完(wan)全考(kao)慮過(guo)的。在平衡狀態下(xia)，不能在所有正常模型中選(xuan)(xuan)擇某些組(zu)的輸出交(jiao)(jiao)流(liu)(liu)接(jie)觸(chu)(chu)器(qi)的電(dian)流(liu)(liu)水平。基本上，電(dian)流(liu)(liu)水平是通過(guo)一(yi)個步(bu)驟選(xuan)(xuan)擇的，該步(bu)驟會導致(zhi)交(jiao)(jiao)流(liu)(liu)接(jie)觸(chu)(chu)器(qi)在高(gao)溫天氣(qi)下(xia)運行期間燒(shao)斷(duan)。

根據電(dian)(dian)氣(qi)設備的接線規定(ding)，接線盒(he)可安(an)裝在封閉(bi)(bi)或(huo)(huo)半封閉(bi)(bi)的金屬外殼中或(huo)(huo)屏幕上(shang)，以(yi)(yi)形成配電(dian)(dian)室設備。如果一切正常(chang)，可以(yi)(yi)使用手(shou)或(huo)(huo)控制(zhi)開關連接或(huo)(huo)斷開電(dian)(dian)源電(dian)(dian)路。常(chang)見(jian)的錯誤或(huo)(huo)異常(chang)取決于家用電(dian)(dian)器的維(wei)護，以(yi)(yi)斷開電(dian)(dian)路或(huo)(huo)警報。識別儀可以(yi)(yi)在信息模式下顯(xian)示各種(zhong)主要參數(shu)，還可以(yi)(yi)調整某些電(dian)(dian)氣(qi)設備的主要參數(shu)，并提(ti)醒或(huo)(huo)發出所有正常(chang)工作(zuo)設置的偏差信號。常(chang)用于發電(dian)(dian)，配電(dian)(dian)和變電(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)(yong)作(zuo)電(dian)(dian)壓(ya)等級在3.6 kV~550 kV的電(dian)(dian)氣產(chan)品作(zuo)為高(gao)壓(ya)隔離開關(guan)，有接地開關(guan)，高(gao)壓(ya)斷路器，自動(dong)高(gao)壓(ya)重(zhong)合和(he)斷開裝(zhuang)置(zhi)，高(gao)壓(ya)操(cao)作(zuo)機構，防爆高(gao)壓(ya)配電(dian)(dian)裝(zhuang)置(zhi)和(he)高(gao)壓(ya)開關(guan)柜(ju)(ju)等不(bu)同類別。通常，連接到系(xi)(xi)統(tong)(tong)(tong)主母線的電(dian)(dian)容(rong)器柜(ju)(ju)用(yong)(yong)于(yu)中(zhong)央無功功率補償(chang)，并(bing)(bing)且通常與(yu)輸(shu)入柜(ju)(ju)并(bing)(bing)聯安裝(zhuang)（系(xi)(xi)統(tong)(tong)(tong)具有PT柜(ju)(ju)，應為高(gao)壓(ya)系(xi)(xi)統(tong)(tong)(tong)，而低壓(ya)系(xi)(xi)統(tong)(tong)(tong)沒有PT柜(ju)(ju)- PT柜(ju)(ju)相當于(yu)降低變(bian)壓(ya)器，只需(xu)要(yao)低壓(ya)變(bian)壓(ya)器，但是(shi)電(dian)(dian)容(rong)器柜(ju)(ju)很(hen)少用(yong)(yong)于(yu)高(gao)壓(ya)系(xi)(xi)統(tong)(tong)(tong)中(zhong)，并(bing)(bing)且高(gao)壓(ya)電(dian)(dian)容(rong)器很(hen)難制造，并(bing)(bing)且通常在低壓(ya)側進行集(ji)中(zhong)補償(chang)。
