中電(dian)氣(qi)設備選擇不(bu)當(dang)造(zao)成的(de)(de)(de)常(chang)見(jian)錯誤：生產過(guo)(guo)程(cheng)中交流(liu)(liu)(liu)接(jie)觸器(qi)的(de)(de)(de)體積選擇不(bu)當(dang)，不(bu)同(tong)組的(de)(de)(de)插座(zuo)控制(zhi)電(dian)路安裝了(le)相(xiang)同(tong)體積的(de)(de)(de)交流(liu)(liu)(liu)接(jie)觸器(qi)，三相(xiang)負(fu)載的(de)(de)(de)差異(yi)不(bu)完(wan)全考慮過(guo)(guo)的(de)(de)(de)。在(zai)平衡狀(zhuang)態(tai)下，不(bu)能(neng)在(zai)所有正常(chang)模型(xing)中選擇某些組的(de)(de)(de)輸出交流(liu)(liu)(liu)接(jie)觸器(qi)的(de)(de)(de)電(dian)流(liu)(liu)(liu)水平。基本上，電(dian)流(liu)(liu)(liu)水平是(shi)通過(guo)(guo)一個步驟(zou)(zou)選擇的(de)(de)(de)，該(gai)步驟(zou)(zou)會導致交流(liu)(liu)(liu)接(jie)觸器(qi)在(zai)高溫天氣(qi)下運行期間燒(shao)斷。

根據(ju)電(dian)(dian)(dian)(dian)氣(qi)設(she)備的接(jie)線規定，接(jie)線盒可(ke)安裝在封閉或(huo)(huo)半封閉的金(jin)屬(shu)外殼中或(huo)(huo)屏幕上，以形(xing)成配電(dian)(dian)(dian)(dian)室設(she)備。如果一切(qie)正常，可(ke)以使用手或(huo)(huo)控制開(kai)關連接(jie)或(huo)(huo)斷開(kai)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的錯誤或(huo)(huo)異常取(qu)決于(yu)家用電(dian)(dian)(dian)(dian)器(qi)的維護，以斷開(kai)電(dian)(dian)(dian)(dian)路或(huo)(huo)警報。識別(bie)儀可(ke)以在信(xin)息模式下顯示各種主要參(can)(can)數，還可(ke)以調(diao)整某些電(dian)(dian)(dian)(dian)氣(qi)設(she)備的主要參(can)(can)數，并(bing)提醒或(huo)(huo)發出(chu)所(suo)有正常工作(zuo)設(she)置的偏差信(xin)號。常用于(yu)發電(dian)(dian)(dian)(dian)，配電(dian)(dian)(dian)(dian)和(he)變電(dian)(dian)(dian)(dian)站。
