中電氣設(she)備選(xuan)擇不當造成的(de)(de)常(chang)見錯誤：生產過(guo)程中交(jiao)(jiao)(jiao)流接觸器(qi)(qi)的(de)(de)體積(ji)選(xuan)擇不當，不同組的(de)(de)插座控制電路(lu)安裝了相同體積(ji)的(de)(de)交(jiao)(jiao)(jiao)流接觸器(qi)(qi)，三(san)相負(fu)載的(de)(de)差異不完全考慮過(guo)的(de)(de)。在(zai)平衡狀態(tai)下，不能在(zai)所有正(zheng)常(chang)模型中選(xuan)擇某些組的(de)(de)輸(shu)出交(jiao)(jiao)(jiao)流接觸器(qi)(qi)的(de)(de)電流水平。基(ji)本上，電流水平是通過(guo)一個步驟選(xuan)擇的(de)(de)，該(gai)步驟會導致交(jiao)(jiao)(jiao)流接觸器(qi)(qi)在(zai)高溫(wen)天氣下運(yun)行期間燒(shao)斷。

根據電(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)接線規定，接線盒可安裝在封閉(bi)或(huo)(huo)(huo)(huo)半封閉(bi)的(de)金屬(shu)外(wai)殼中或(huo)(huo)(huo)(huo)屏幕上，以(yi)形成配(pei)電(dian)(dian)(dian)(dian)室設(she)備(bei)。如果一(yi)切(qie)正常，可以(yi)使用(yong)手(shou)或(huo)(huo)(huo)(huo)控制開關(guan)連(lian)接或(huo)(huo)(huo)(huo)斷開電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的(de)錯誤或(huo)(huo)(huo)(huo)異(yi)常取決(jue)于家用(yong)電(dian)(dian)(dian)(dian)器的(de)維護(hu)，以(yi)斷開電(dian)(dian)(dian)(dian)路或(huo)(huo)(huo)(huo)警報。識別儀可以(yi)在信(xin)息模式下顯示各種主要參(can)數(shu)，還可以(yi)調(diao)整某些電(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)主要參(can)數(shu)，并提醒(xing)或(huo)(huo)(huo)(huo)發(fa)出所有正常工(gong)作設(she)置的(de)偏差信(xin)號。常用(yong)于發(fa)電(dian)(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站。
