中電(dian)氣(qi)設備選擇(ze)不(bu)當(dang)造成的常(chang)(chang)見錯誤：生產過程(cheng)中交(jiao)流(liu)(liu)接觸(chu)(chu)(chu)器(qi)(qi)(qi)的體積(ji)選擇(ze)不(bu)當(dang)，不(bu)同組的插(cha)座控(kong)制電(dian)路安裝了相(xiang)同體積(ji)的交(jiao)流(liu)(liu)接觸(chu)(chu)(chu)器(qi)(qi)(qi)，三(san)相(xiang)負載的差異不(bu)完(wan)全考慮(lv)過的。在平衡狀(zhuang)態下，不(bu)能在所有正常(chang)(chang)模型中選擇(ze)某(mou)些(xie)組的輸出交(jiao)流(liu)(liu)接觸(chu)(chu)(chu)器(qi)(qi)(qi)的電(dian)流(liu)(liu)水(shui)(shui)平。基本上，電(dian)流(liu)(liu)水(shui)(shui)平是通過一個步驟選擇(ze)的，該步驟會導(dao)致交(jiao)流(liu)(liu)接觸(chu)(chu)(chu)器(qi)(qi)(qi)在高(gao)溫天氣(qi)下運行期間(jian)燒斷。

根據電(dian)(dian)(dian)氣(qi)設備(bei)的接(jie)(jie)線(xian)規定(ding)，接(jie)(jie)線(xian)盒可(ke)安裝在封閉(bi)或半封閉(bi)的金屬外殼中(zhong)或屏(ping)幕上，以形成配電(dian)(dian)(dian)室設備(bei)。如果一(yi)切正常，可(ke)以使用(yong)手或控制開關連(lian)接(jie)(jie)或斷開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的錯誤或異常取決于(yu)家用(yong)電(dian)(dian)(dian)器的維護，以斷開電(dian)(dian)(dian)路或警報。識別儀可(ke)以在信(xin)息(xi)模式(shi)下顯示各種主要參(can)數，還可(ke)以調整某些電(dian)(dian)(dian)氣(qi)設備(bei)的主要參(can)數，并提醒或發出所有正常工作設置的偏差信(xin)號。常用(yong)于(yu)發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站(zhan)。
