中電(dian)(dian)氣(qi)(qi)設備選擇(ze)不(bu)(bu)(bu)當造(zao)成的(de)常見錯誤：生產過程中交流接觸器的(de)體(ti)積(ji)選擇(ze)不(bu)(bu)(bu)當，不(bu)(bu)(bu)同(tong)組的(de)插座控制電(dian)(dian)路安(an)裝(zhuang)了相同(tong)體(ti)積(ji)的(de)交流接觸器，三相負載(zai)的(de)差(cha)異不(bu)(bu)(bu)完全考慮過的(de)。在平衡(heng)狀態下，不(bu)(bu)(bu)能在所(suo)有正常模型中選擇(ze)某些組的(de)輸出交流接觸器的(de)電(dian)(dian)流水平。基本上，電(dian)(dian)流水平是通過一個(ge)步驟選擇(ze)的(de)，該(gai)步驟會導致(zhi)交流接觸器在高溫天氣(qi)(qi)下運行期間(jian)燒斷。

根據(ju)電(dian)(dian)氣設(she)備的(de)接線規定(ding)，接線盒可(ke)安(an)裝在封閉或(huo)(huo)半封閉的(de)金屬外殼中(zhong)或(huo)(huo)屏幕上，以(yi)形成配電(dian)(dian)室設(she)備。如果一切正(zheng)常(chang)，可(ke)以(yi)使用手或(huo)(huo)控制開關(guan)連接或(huo)(huo)斷開電(dian)(dian)源(yuan)電(dian)(dian)路(lu)。常(chang)見(jian)的(de)錯誤或(huo)(huo)異常(chang)取決(jue)于家用電(dian)(dian)器的(de)維護，以(yi)斷開電(dian)(dian)路(lu)或(huo)(huo)警報。識別儀可(ke)以(yi)在信息模式下顯示(shi)各種(zhong)主(zhu)要參數，還(huan)可(ke)以(yi)調整某些電(dian)(dian)氣設(she)備的(de)主(zhu)要參數，并提醒(xing)或(huo)(huo)發出所有正(zheng)常(chang)工(gong)作設(she)置的(de)偏差信號。常(chang)用于發電(dian)(dian)，配電(dian)(dian)和(he)變(bian)電(dian)(dian)站。
