中電氣設備選(xuan)擇不(bu)當(dang)造成的常見錯誤：生產過程中交流(liu)(liu)(liu)(liu)接觸器的體積選(xuan)擇不(bu)當(dang)，不(bu)同(tong)組的插座控制電路(lu)安裝了相(xiang)同(tong)體積的交流(liu)(liu)(liu)(liu)接觸器，三相(xiang)負載的差異不(bu)完全(quan)考慮(lv)過的。在平衡狀態下(xia)，不(bu)能(neng)在所有(you)正(zheng)常模型中選(xuan)擇某些組的輸出交流(liu)(liu)(liu)(liu)接觸器的電流(liu)(liu)(liu)(liu)水(shui)平。基本(ben)上，電流(liu)(liu)(liu)(liu)水(shui)平是通過一個步(bu)驟(zou)選(xuan)擇的，該步(bu)驟(zou)會導致交流(liu)(liu)(liu)(liu)接觸器在高溫天(tian)氣下(xia)運行期間燒斷。

根據電(dian)(dian)(dian)氣設備的(de)接(jie)線規定，接(jie)線盒可安裝在(zai)(zai)封閉(bi)或(huo)半封閉(bi)的(de)金屬外殼中或(huo)屏幕上，以(yi)形成配電(dian)(dian)(dian)室設備。如果(guo)一切正常，可以(yi)使用(yong)手(shou)或(huo)控制(zhi)開關連接(jie)或(huo)斷(duan)開電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)。常見的(de)錯(cuo)誤或(huo)異常取決于家用(yong)電(dian)(dian)(dian)器(qi)的(de)維護(hu)，以(yi)斷(duan)開電(dian)(dian)(dian)路(lu)或(huo)警報。識別(bie)儀(yi)可以(yi)在(zai)(zai)信息(xi)模式下顯(xian)示各種主要參(can)數(shu)，還(huan)可以(yi)調整某些電(dian)(dian)(dian)氣設備的(de)主要參(can)數(shu)，并提醒或(huo)發出所有正常工作(zuo)設置(zhi)的(de)偏差信號。常用(yong)于發電(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(yong)作(zuo)(zuo)電(dian)(dian)(dian)壓(ya)(ya)(ya)等(deng)級(ji)在(zai)3.6 kV~550 kV的電(dian)(dian)(dian)氣產品作(zuo)(zuo)為(wei)高(gao)(gao)壓(ya)(ya)(ya)隔離開關，有接地(di)開關，高(gao)(gao)壓(ya)(ya)(ya)斷(duan)路(lu)器，自動(dong)高(gao)(gao)壓(ya)(ya)(ya)重合和斷(duan)開裝(zhuang)置(zhi)，高(gao)(gao)壓(ya)(ya)(ya)操作(zuo)(zuo)機(ji)構(gou)，防爆高(gao)(gao)壓(ya)(ya)(ya)配電(dian)(dian)(dian)裝(zhuang)置(zhi)和高(gao)(gao)壓(ya)(ya)(ya)開關柜(ju)(ju)等(deng)不(bu)同類別。通常(chang)，連接到(dao)系統(tong)主母線(xian)的電(dian)(dian)(dian)容器柜(ju)(ju)用(yong)于中(zhong)(zhong)央無功功率補償，并且通常(chang)與輸入柜(ju)(ju)并聯安裝(zhuang)（系統(tong)具有PT柜(ju)(ju)，應為(wei)高(gao)(gao)壓(ya)(ya)(ya)系統(tong)，而低(di)壓(ya)(ya)(ya)系統(tong)沒有PT柜(ju)(ju)- PT柜(ju)(ju)相當于降(jiang)低(di)變壓(ya)(ya)(ya)器，只需要低(di)壓(ya)(ya)(ya)變壓(ya)(ya)(ya)器，但是電(dian)(dian)(dian)容器柜(ju)(ju)很(hen)少用(yong)于高(gao)(gao)壓(ya)(ya)(ya)系統(tong)中(zhong)(zhong)，并且高(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)容器很(hen)難(nan)制(zhi)造(zao)，并且通常(chang)在(zai)低(di)壓(ya)(ya)(ya)側進行集中(zhong)(zhong)補償。
