中(zhong)電氣設(she)備選(xuan)擇(ze)不當造成(cheng)的(de)常見錯誤：生產過程中(zhong)交流(liu)接觸(chu)器(qi)(qi)的(de)體積(ji)選(xuan)擇(ze)不當，不同(tong)組(zu)(zu)的(de)插(cha)座控制電路(lu)安裝了相同(tong)體積(ji)的(de)交流(liu)接觸(chu)器(qi)(qi)，三相負(fu)載的(de)差異不完全考慮過的(de)。在平衡(heng)狀態下，不能在所有正常模型中(zhong)選(xuan)擇(ze)某些組(zu)(zu)的(de)輸出交流(liu)接觸(chu)器(qi)(qi)的(de)電流(liu)水平。基(ji)本上，電流(liu)水平是(shi)通過一(yi)個步驟(zou)選(xuan)擇(ze)的(de)，該步驟(zou)會導(dao)致交流(liu)接觸(chu)器(qi)(qi)在高(gao)溫(wen)天氣下運行期間燒斷。

根據(ju)電(dian)(dian)(dian)(dian)氣(qi)設(she)(she)備的(de)接(jie)線規定(ding)，接(jie)線盒可(ke)(ke)安(an)裝在封(feng)閉(bi)或(huo)(huo)半封(feng)閉(bi)的(de)金屬(shu)外殼中(zhong)或(huo)(huo)屏幕上，以形成配電(dian)(dian)(dian)(dian)室(shi)設(she)(she)備。如果一切正(zheng)常，可(ke)(ke)以使用手或(huo)(huo)控制開關連接(jie)或(huo)(huo)斷開電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的(de)錯(cuo)誤或(huo)(huo)異常取決于(yu)家用電(dian)(dian)(dian)(dian)器的(de)維護，以斷開電(dian)(dian)(dian)(dian)路或(huo)(huo)警報。識別儀可(ke)(ke)以在信息模式下顯(xian)示各種主要(yao)參數，還可(ke)(ke)以調整(zheng)某(mou)些電(dian)(dian)(dian)(dian)氣(qi)設(she)(she)備的(de)主要(yao)參數，并提醒(xing)或(huo)(huo)發出(chu)所(suo)有正(zheng)常工作設(she)(she)置的(de)偏(pian)差信號(hao)。常用于(yu)發電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和變(bian)電(dian)(dian)(dian)(dian)站。
