中(zhong)電氣(qi)(qi)設備選擇(ze)不當造成(cheng)的(de)常見錯(cuo)誤：生(sheng)產過程中(zhong)交流接(jie)觸(chu)器的(de)體積選擇(ze)不當，不同組的(de)插座控制電路安裝(zhuang)了相同體積的(de)交流接(jie)觸(chu)器，三相負載(zai)的(de)差異不完全考慮(lv)過的(de)。在(zai)平(ping)衡狀態(tai)下(xia)，不能在(zai)所有(you)正(zheng)常模(mo)型中(zhong)選擇(ze)某些組的(de)輸出交流接(jie)觸(chu)器的(de)電流水平(ping)。基本上，電流水平(ping)是通過一個(ge)步(bu)驟選擇(ze)的(de)，該步(bu)驟會導致交流接(jie)觸(chu)器在(zai)高(gao)溫(wen)天氣(qi)(qi)下(xia)運行期(qi)間(jian)燒斷。

根據電(dian)(dian)(dian)(dian)氣設(she)備的(de)(de)接線規定，接線盒可安裝(zhuang)在(zai)封(feng)閉或(huo)半封(feng)閉的(de)(de)金(jin)屬外殼中或(huo)屏幕上，以(yi)(yi)形成配電(dian)(dian)(dian)(dian)室設(she)備。如果一切正(zheng)常(chang)(chang)，可以(yi)(yi)使(shi)用手或(huo)控制開(kai)關(guan)連(lian)接或(huo)斷開(kai)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常(chang)(chang)見的(de)(de)錯誤或(huo)異常(chang)(chang)取決于(yu)家用電(dian)(dian)(dian)(dian)器的(de)(de)維護(hu)，以(yi)(yi)斷開(kai)電(dian)(dian)(dian)(dian)路或(huo)警(jing)報。識別(bie)儀(yi)可以(yi)(yi)在(zai)信息模式下(xia)顯示各種主(zhu)要參數(shu)，還可以(yi)(yi)調整某些電(dian)(dian)(dian)(dian)氣設(she)備的(de)(de)主(zhu)要參數(shu)，并提醒或(huo)發出所(suo)有(you)正(zheng)常(chang)(chang)工作設(she)置的(de)(de)偏差信號(hao)。常(chang)(chang)用于(yu)發電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站(zhan)。

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)電壓(ya)(ya)(ya)(ya)(ya)等(deng)級在3.6 kV~550 kV的電氣產品作(zuo)為高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)隔(ge)離開關(guan)，有接地(di)開關(guan)，高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)斷路器(qi)，自動高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)重合和斷開裝置，高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)操作(zuo)機構，防爆高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)配電裝置和高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)開關(guan)柜(ju)(ju)(ju)等(deng)不同類別。通常，連接到系(xi)統主母(mu)線的電容器(qi)柜(ju)(ju)(ju)用(yong)(yong)于中央無功(gong)(gong)功(gong)(gong)率補償，并且通常與輸(shu)入柜(ju)(ju)(ju)并聯安裝（系(xi)統具(ju)有PT柜(ju)(ju)(ju)，應為高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)系(xi)統，而(er)低壓(ya)(ya)(ya)(ya)(ya)系(xi)統沒有PT柜(ju)(ju)(ju)- PT柜(ju)(ju)(ju)相(xiang)當于降低變壓(ya)(ya)(ya)(ya)(ya)器(qi)，只需要低壓(ya)(ya)(ya)(ya)(ya)變壓(ya)(ya)(ya)(ya)(ya)器(qi)，但是(shi)電容器(qi)柜(ju)(ju)(ju)很(hen)少用(yong)(yong)于高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)系(xi)統中，并且高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)電容器(qi)很(hen)難制造，并且通常在低壓(ya)(ya)(ya)(ya)(ya)側進(jin)行(xing)集中補償。
