中(zhong)(zhong)電(dian)氣設備選(xuan)擇不當(dang)造成的(de)常見錯誤：生產(chan)過(guo)程中(zhong)(zhong)交(jiao)流接觸器(qi)的(de)體(ti)積(ji)選(xuan)擇不當(dang)，不同(tong)組的(de)插座控制電(dian)路安(an)裝了相同(tong)體(ti)積(ji)的(de)交(jiao)流接觸器(qi)，三相負載的(de)差異不完全考慮過(guo)的(de)。在(zai)(zai)平衡狀(zhuang)態下，不能在(zai)(zai)所有正常模型中(zhong)(zhong)選(xuan)擇某些組的(de)輸出(chu)交(jiao)流接觸器(qi)的(de)電(dian)流水(shui)平。基本上，電(dian)流水(shui)平是(shi)通(tong)過(guo)一(yi)個(ge)步驟選(xuan)擇的(de)，該步驟會導致(zhi)交(jiao)流接觸器(qi)在(zai)(zai)高溫天氣下運行期(qi)間燒斷。

根據(ju)電(dian)(dian)(dian)氣設(she)備(bei)的(de)接線規定，接線盒可(ke)(ke)安裝在封閉或(huo)半封閉的(de)金屬(shu)外殼(ke)中或(huo)屏幕上，以形成配(pei)電(dian)(dian)(dian)室設(she)備(bei)。如果一切正常，可(ke)(ke)以使(shi)用手或(huo)控制(zhi)開關連接或(huo)斷開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的(de)錯誤或(huo)異常取決于家用電(dian)(dian)(dian)器的(de)維護，以斷開電(dian)(dian)(dian)路或(huo)警報。識別儀可(ke)(ke)以在信息模式下(xia)顯示各種主要(yao)(yao)參數，還可(ke)(ke)以調整某些(xie)電(dian)(dian)(dian)氣設(she)備(bei)的(de)主要(yao)(yao)參數，并提醒或(huo)發出所有正常工(gong)作設(she)置的(de)偏差信號。常用于發電(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)和變電(dian)(dian)(dian)站。
