中(zhong)電(dian)氣設備(bei)選擇(ze)不(bu)當造成的(de)常見(jian)錯誤(wu)：生產過(guo)程中(zhong)交流(liu)接觸(chu)器(qi)(qi)的(de)體積選擇(ze)不(bu)當，不(bu)同(tong)組的(de)插座控制電(dian)路安裝了相(xiang)同(tong)體積的(de)交流(liu)接觸(chu)器(qi)(qi)，三相(xiang)負載(zai)的(de)差異不(bu)完全考慮過(guo)的(de)。在(zai)平(ping)衡狀態下，不(bu)能在(zai)所有正(zheng)常模型(xing)中(zhong)選擇(ze)某些組的(de)輸出交流(liu)接觸(chu)器(qi)(qi)的(de)電(dian)流(liu)水平(ping)。基本上，電(dian)流(liu)水平(ping)是通過(guo)一(yi)個步驟選擇(ze)的(de)，該步驟會導致(zhi)交流(liu)接觸(chu)器(qi)(qi)在(zai)高(gao)溫天氣下運(yun)行期間燒斷。

根據電(dian)(dian)氣設(she)備的(de)(de)接(jie)線(xian)規定，接(jie)線(xian)盒(he)可(ke)(ke)安裝(zhuang)在封(feng)閉(bi)或半封(feng)閉(bi)的(de)(de)金屬外殼中或屏幕(mu)上，以形成(cheng)配電(dian)(dian)室設(she)備。如(ru)果一切正常，可(ke)(ke)以使用手或控(kong)制(zhi)開關連接(jie)或斷開電(dian)(dian)源電(dian)(dian)路。常見的(de)(de)錯誤或異常取(qu)決于家用電(dian)(dian)器的(de)(de)維護(hu)，以斷開電(dian)(dian)路或警報。識別儀可(ke)(ke)以在信息模式下顯示(shi)各種主要(yao)參數，還(huan)可(ke)(ke)以調整(zheng)某(mou)些電(dian)(dian)氣設(she)備的(de)(de)主要(yao)參數，并提醒或發出(chu)所有正常工作設(she)置的(de)(de)偏差信號。常用于發電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
