中(zhong)電氣設備選(xuan)擇(ze)不當造成(cheng)的(de)(de)常(chang)見錯誤：生產過(guo)程中(zhong)交流接(jie)(jie)觸器的(de)(de)體(ti)積(ji)選(xuan)擇(ze)不當，不同組的(de)(de)插座控制(zhi)電路安裝(zhuang)了相同體(ti)積(ji)的(de)(de)交流接(jie)(jie)觸器，三相負載的(de)(de)差異不完全考慮過(guo)的(de)(de)。在(zai)平衡狀態下(xia)，不能在(zai)所有正(zheng)常(chang)模型中(zhong)選(xuan)擇(ze)某些組的(de)(de)輸出(chu)交流接(jie)(jie)觸器的(de)(de)電流水(shui)平。基本上，電流水(shui)平是通過(guo)一(yi)個步(bu)(bu)驟選(xuan)擇(ze)的(de)(de)，該步(bu)(bu)驟會導致交流接(jie)(jie)觸器在(zai)高溫天氣下(xia)運行期間燒(shao)斷。

根據電(dian)(dian)氣設(she)備(bei)的接(jie)線規定，接(jie)線盒可安裝(zhuang)在封閉(bi)或(huo)(huo)半封閉(bi)的金屬外殼中或(huo)(huo)屏(ping)幕上，以形成配(pei)電(dian)(dian)室設(she)備(bei)。如果一切正(zheng)常，可以使用手(shou)或(huo)(huo)控制開關連(lian)接(jie)或(huo)(huo)斷(duan)開電(dian)(dian)源電(dian)(dian)路。常見(jian)的錯(cuo)誤(wu)或(huo)(huo)異常取決于家用電(dian)(dian)器的維護，以斷(duan)開電(dian)(dian)路或(huo)(huo)警報(bao)。識別(bie)儀可以在信息模式下顯(xian)示各種主要(yao)參(can)數，還(huan)可以調整某些電(dian)(dian)氣設(she)備(bei)的主要(yao)參(can)數，并提醒或(huo)(huo)發出所有正(zheng)常工作設(she)置的偏差(cha)信號。常用于發電(dian)(dian)，配(pei)電(dian)(dian)和變(bian)電(dian)(dian)站。
