中(zhong)電(dian)氣(qi)設備(bei)選擇(ze)不(bu)當造成的(de)常見錯誤：生產過程中(zhong)交(jiao)流(liu)(liu)接觸器(qi)的(de)體積選擇(ze)不(bu)當，不(bu)同(tong)組(zu)的(de)插座控制電(dian)路安裝了相同(tong)體積的(de)交(jiao)流(liu)(liu)接觸器(qi)，三相負載的(de)差(cha)異(yi)不(bu)完(wan)全考(kao)慮過的(de)。在(zai)平(ping)衡狀態下，不(bu)能在(zai)所有正常模型中(zhong)選擇(ze)某些組(zu)的(de)輸(shu)出交(jiao)流(liu)(liu)接觸器(qi)的(de)電(dian)流(liu)(liu)水平(ping)。基本上，電(dian)流(liu)(liu)水平(ping)是通過一個步驟(zou)選擇(ze)的(de)，該步驟(zou)會導(dao)致交(jiao)流(liu)(liu)接觸器(qi)在(zai)高溫天氣(qi)下運行(xing)期間燒斷。

根據電(dian)(dian)(dian)氣設備的(de)(de)接(jie)線(xian)(xian)規定(ding)，接(jie)線(xian)(xian)盒(he)可安(an)裝(zhuang)在封閉或半(ban)封閉的(de)(de)金屬外殼中(zhong)或屏幕上，以形成配電(dian)(dian)(dian)室設備。如果一切正常，可以使用手或控制開(kai)關連(lian)接(jie)或斷開(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)。常見的(de)(de)錯誤或異常取決于家用電(dian)(dian)(dian)器的(de)(de)維護(hu)，以斷開(kai)電(dian)(dian)(dian)路(lu)或警報(bao)。識(shi)別儀可以在信(xin)息模式下顯示各種主要參(can)數(shu)，還可以調整某(mou)些電(dian)(dian)(dian)氣設備的(de)(de)主要參(can)數(shu)，并提醒(xing)或發出所(suo)有正常工作設置的(de)(de)偏(pian)差信(xin)號。常用于發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站。
