中(zhong)電(dian)氣設備選(xuan)擇不(bu)當造成的(de)(de)常見錯誤：生產過(guo)程(cheng)中(zhong)交(jiao)(jiao)流(liu)接觸(chu)器的(de)(de)體積(ji)選(xuan)擇不(bu)當，不(bu)同組(zu)(zu)的(de)(de)插座(zuo)控制電(dian)路安裝了相同體積(ji)的(de)(de)交(jiao)(jiao)流(liu)接觸(chu)器，三(san)相負載(zai)的(de)(de)差異不(bu)完全考慮過(guo)的(de)(de)。在平衡狀態下，不(bu)能(neng)在所有正常模型中(zhong)選(xuan)擇某些組(zu)(zu)的(de)(de)輸出交(jiao)(jiao)流(liu)接觸(chu)器的(de)(de)電(dian)流(liu)水平。基本(ben)上，電(dian)流(liu)水平是通(tong)過(guo)一個步(bu)驟(zou)選(xuan)擇的(de)(de)，該步(bu)驟(zou)會導致交(jiao)(jiao)流(liu)接觸(chu)器在高溫天氣下運(yun)行期間(jian)燒(shao)斷。

根據(ju)電(dian)(dian)(dian)氣設(she)備(bei)的(de)接線(xian)規(gui)定(ding)，接線(xian)盒可安(an)裝在封閉或(huo)半(ban)封閉的(de)金屬(shu)外殼(ke)中或(huo)屏幕上，以(yi)(yi)(yi)(yi)形(xing)成配電(dian)(dian)(dian)室設(she)備(bei)。如(ru)果一切正常(chang)，可以(yi)(yi)(yi)(yi)使(shi)用手或(huo)控制開(kai)關連接或(huo)斷開(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)。常(chang)見(jian)的(de)錯(cuo)誤或(huo)異常(chang)取決于家用電(dian)(dian)(dian)器的(de)維(wei)護，以(yi)(yi)(yi)(yi)斷開(kai)電(dian)(dian)(dian)路(lu)或(huo)警報。識別儀(yi)可以(yi)(yi)(yi)(yi)在信息模式下顯示各種主(zhu)(zhu)要參數，還可以(yi)(yi)(yi)(yi)調整某(mou)些電(dian)(dian)(dian)氣設(she)備(bei)的(de)主(zhu)(zhu)要參數，并提醒(xing)或(huo)發出(chu)所有正常(chang)工(gong)作設(she)置(zhi)的(de)偏差信號。常(chang)用于發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站(zhan)。
