中電氣設備(bei)選擇(ze)不當造成的常見(jian)錯誤：生產(chan)過程中交(jiao)流(liu)接(jie)觸(chu)器的體(ti)積選擇(ze)不當，不同組的插座控制電路安裝了相同體(ti)積的交(jiao)流(liu)接(jie)觸(chu)器，三(san)相負載的差(cha)異不完全考慮過的。在平(ping)衡狀態下，不能(neng)在所有正常模(mo)型中選擇(ze)某些組的輸出交(jiao)流(liu)接(jie)觸(chu)器的電流(liu)水平(ping)。基本(ben)上，電流(liu)水平(ping)是(shi)通過一個步(bu)(bu)驟選擇(ze)的，該步(bu)(bu)驟會(hui)導致交(jiao)流(liu)接(jie)觸(chu)器在高溫天氣下運行期間燒斷。

根(gen)據電(dian)(dian)氣設備(bei)的接(jie)線(xian)規(gui)定，接(jie)線(xian)盒可(ke)安裝在(zai)封閉(bi)或半封閉(bi)的金屬外殼(ke)中或屏幕上，以(yi)形成配電(dian)(dian)室設備(bei)。如果一切正常(chang)，可(ke)以(yi)使用(yong)手(shou)或控制開關連接(jie)或斷開電(dian)(dian)源電(dian)(dian)路(lu)。常(chang)見的錯誤或異常(chang)取決于家用(yong)電(dian)(dian)器的維(wei)護，以(yi)斷開電(dian)(dian)路(lu)或警報。識別儀可(ke)以(yi)在(zai)信息模式下(xia)顯(xian)示各(ge)種主要參(can)數(shu)(shu)，還可(ke)以(yi)調(diao)整某(mou)些電(dian)(dian)氣設備(bei)的主要參(can)數(shu)(shu)，并提醒或發出(chu)所有正常(chang)工(gong)作設置的偏(pian)差信號。常(chang)用(yong)于發電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
