中(zhong)電(dian)氣設備選擇不(bu)(bu)當造(zao)成的(de)常(chang)見錯誤：生(sheng)產(chan)過程(cheng)中(zhong)交流(liu)接觸(chu)(chu)器(qi)(qi)的(de)體積選擇不(bu)(bu)當，不(bu)(bu)同(tong)組(zu)的(de)插座(zuo)控制電(dian)路安(an)裝了相同(tong)體積的(de)交流(liu)接觸(chu)(chu)器(qi)(qi)，三相負載的(de)差異不(bu)(bu)完全考慮過的(de)。在平衡狀態下，不(bu)(bu)能在所有正常(chang)模(mo)型中(zhong)選擇某些組(zu)的(de)輸出交流(liu)接觸(chu)(chu)器(qi)(qi)的(de)電(dian)流(liu)水平。基(ji)本上，電(dian)流(liu)水平是(shi)通過一個步(bu)驟(zou)選擇的(de)，該(gai)步(bu)驟(zou)會導致交流(liu)接觸(chu)(chu)器(qi)(qi)在高溫天氣下運(yun)行期間(jian)燒斷。

根據(ju)電(dian)(dian)(dian)氣設(she)備的(de)(de)接(jie)線規定，接(jie)線盒可(ke)安裝在封(feng)閉或(huo)半封(feng)閉的(de)(de)金屬外殼中(zhong)或(huo)屏幕上(shang)，以形(xing)成配電(dian)(dian)(dian)室設(she)備。如果一切正常(chang)，可(ke)以使用(yong)(yong)手或(huo)控制開(kai)關連接(jie)或(huo)斷(duan)開(kai)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)(lu)。常(chang)見的(de)(de)錯誤(wu)或(huo)異常(chang)取決于(yu)家用(yong)(yong)電(dian)(dian)(dian)器的(de)(de)維護，以斷(duan)開(kai)電(dian)(dian)(dian)路(lu)(lu)或(huo)警報(bao)。識別儀可(ke)以在信息模式下顯示各種主(zhu)要參數，還可(ke)以調整某(mou)些電(dian)(dian)(dian)氣設(she)備的(de)(de)主(zhu)要參數，并提醒或(huo)發出所有正常(chang)工(gong)作設(she)置的(de)(de)偏(pian)差信號。常(chang)用(yong)(yong)于(yu)發電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站。
