中電(dian)氣設備選擇(ze)(ze)(ze)不(bu)當(dang)(dang)造成的(de)(de)(de)(de)常見錯誤：生(sheng)產過程中交(jiao)流(liu)接(jie)觸器(qi)(qi)的(de)(de)(de)(de)體(ti)(ti)積選擇(ze)(ze)(ze)不(bu)當(dang)(dang)，不(bu)同(tong)組的(de)(de)(de)(de)插座(zuo)控制電(dian)路(lu)安(an)裝了相同(tong)體(ti)(ti)積的(de)(de)(de)(de)交(jiao)流(liu)接(jie)觸器(qi)(qi)，三相負載(zai)的(de)(de)(de)(de)差異不(bu)完全考慮過的(de)(de)(de)(de)。在(zai)平(ping)衡狀態下(xia)，不(bu)能(neng)在(zai)所有(you)正常模型中選擇(ze)(ze)(ze)某些組的(de)(de)(de)(de)輸出(chu)交(jiao)流(liu)接(jie)觸器(qi)(qi)的(de)(de)(de)(de)電(dian)流(liu)水平(ping)。基本上，電(dian)流(liu)水平(ping)是通過一個步(bu)驟選擇(ze)(ze)(ze)的(de)(de)(de)(de)，該步(bu)驟會導致交(jiao)流(liu)接(jie)觸器(qi)(qi)在(zai)高(gao)溫(wen)天(tian)氣下(xia)運行期間燒斷。

根據(ju)電(dian)(dian)氣設備的(de)接線規定，接線盒可(ke)(ke)安裝在封(feng)閉(bi)(bi)或(huo)(huo)半(ban)封(feng)閉(bi)(bi)的(de)金屬外殼中(zhong)或(huo)(huo)屏幕(mu)上，以形成配電(dian)(dian)室設備。如果一切正常(chang)，可(ke)(ke)以使用手或(huo)(huo)控制開關連接或(huo)(huo)斷開電(dian)(dian)源電(dian)(dian)路(lu)。常(chang)見的(de)錯誤或(huo)(huo)異(yi)常(chang)取決于家(jia)用電(dian)(dian)器的(de)維護，以斷開電(dian)(dian)路(lu)或(huo)(huo)警(jing)報(bao)。識別(bie)儀可(ke)(ke)以在信息模式下顯示各(ge)種主要參數，還(huan)可(ke)(ke)以調整某些電(dian)(dian)氣設備的(de)主要參數，并提醒(xing)或(huo)(huo)發出(chu)所(suo)有正常(chang)工作(zuo)設置(zhi)的(de)偏差信號。常(chang)用于發電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
