中電氣(qi)(qi)設備選(xuan)(xuan)擇(ze)不當(dang)造(zao)成(cheng)的(de)(de)(de)常見錯誤：生產過(guo)(guo)程(cheng)中交(jiao)流(liu)(liu)(liu)接觸器(qi)(qi)(qi)的(de)(de)(de)體(ti)積選(xuan)(xuan)擇(ze)不當(dang)，不同組的(de)(de)(de)插座(zuo)控制電路安裝(zhuang)了相同體(ti)積的(de)(de)(de)交(jiao)流(liu)(liu)(liu)接觸器(qi)(qi)(qi)，三相負載的(de)(de)(de)差異不完全考(kao)慮(lv)過(guo)(guo)的(de)(de)(de)。在(zai)平衡狀態(tai)下，不能(neng)在(zai)所(suo)有正常模型中選(xuan)(xuan)擇(ze)某些組的(de)(de)(de)輸出交(jiao)流(liu)(liu)(liu)接觸器(qi)(qi)(qi)的(de)(de)(de)電流(liu)(liu)(liu)水(shui)平。基本(ben)上(shang)，電流(liu)(liu)(liu)水(shui)平是(shi)通(tong)過(guo)(guo)一個(ge)步(bu)(bu)驟選(xuan)(xuan)擇(ze)的(de)(de)(de)，該步(bu)(bu)驟會導致(zhi)交(jiao)流(liu)(liu)(liu)接觸器(qi)(qi)(qi)在(zai)高溫天氣(qi)(qi)下運行期間(jian)燒斷。

根(gen)據電氣(qi)設備的接線規定，接線盒可安裝在(zai)封閉或(huo)(huo)半封閉的金屬外殼(ke)中或(huo)(huo)屏幕上，以形成配電室設備。如果一切(qie)正常，可以使用(yong)(yong)手或(huo)(huo)控(kong)制(zhi)開(kai)關(guan)連(lian)接或(huo)(huo)斷(duan)開(kai)電源電路。常見的錯誤或(huo)(huo)異常取決于(yu)家用(yong)(yong)電器的維(wei)護，以斷(duan)開(kai)電路或(huo)(huo)警報。識別儀可以在(zai)信(xin)(xin)息模(mo)式下顯示各種主(zhu)(zhu)要(yao)參(can)數，還可以調(diao)整某些電氣(qi)設備的主(zhu)(zhu)要(yao)參(can)數，并(bing)提(ti)醒或(huo)(huo)發(fa)出所有正常工作設置(zhi)的偏差信(xin)(xin)號。常用(yong)(yong)于(yu)發(fa)電，配電和變電站(zhan)。
