中(zhong)電氣設備選(xuan)擇(ze)不當造成(cheng)的常見錯誤：生產過程中(zhong)交(jiao)流(liu)(liu)(liu)接觸(chu)器的體積選(xuan)擇(ze)不當，不同組(zu)的插(cha)座控制(zhi)電路安(an)裝了相(xiang)同體積的交(jiao)流(liu)(liu)(liu)接觸(chu)器，三相(xiang)負載的差異不完全考慮過的。在(zai)平(ping)衡狀態下(xia)(xia)，不能(neng)在(zai)所有正常模型中(zhong)選(xuan)擇(ze)某些組(zu)的輸出交(jiao)流(liu)(liu)(liu)接觸(chu)器的電流(liu)(liu)(liu)水平(ping)。基(ji)本(ben)上，電流(liu)(liu)(liu)水平(ping)是(shi)通過一個步(bu)(bu)驟(zou)選(xuan)擇(ze)的，該步(bu)(bu)驟(zou)會導致(zhi)交(jiao)流(liu)(liu)(liu)接觸(chu)器在(zai)高溫天氣下(xia)(xia)運行(xing)期間燒斷(duan)。

根據電(dian)(dian)(dian)(dian)氣(qi)設備的(de)接(jie)線規(gui)定，接(jie)線盒可安裝(zhuang)在(zai)封閉或半封閉的(de)金屬(shu)外殼中(zhong)或屏幕(mu)上(shang)，以(yi)(yi)形(xing)成(cheng)配電(dian)(dian)(dian)(dian)室設備。如(ru)果一切(qie)正(zheng)常，可以(yi)(yi)使(shi)用手或控制開(kai)關連(lian)接(jie)或斷開(kai)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見(jian)的(de)錯誤或異常取(qu)決于(yu)家用電(dian)(dian)(dian)(dian)器的(de)維護，以(yi)(yi)斷開(kai)電(dian)(dian)(dian)(dian)路或警報。識別儀可以(yi)(yi)在(zai)信息模(mo)式下顯示各種主要參數(shu)(shu)，還可以(yi)(yi)調整某些電(dian)(dian)(dian)(dian)氣(qi)設備的(de)主要參數(shu)(shu)，并提醒或發(fa)出(chu)所有正(zheng)常工作設置(zhi)的(de)偏差信號。常用于(yu)發(fa)電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站(zhan)。
