中(zhong)電(dian)(dian)氣(qi)設備選(xuan)(xuan)擇不(bu)當造(zao)成的(de)(de)(de)(de)(de)常見錯誤：生產過程中(zhong)交(jiao)流接觸器的(de)(de)(de)(de)(de)體積選(xuan)(xuan)擇不(bu)當，不(bu)同(tong)組的(de)(de)(de)(de)(de)插座控制(zhi)電(dian)(dian)路安(an)裝(zhuang)了相同(tong)體積的(de)(de)(de)(de)(de)交(jiao)流接觸器，三相負(fu)載(zai)的(de)(de)(de)(de)(de)差異不(bu)完全考慮(lv)過的(de)(de)(de)(de)(de)。在平(ping)衡狀態下，不(bu)能(neng)在所有正常模型中(zhong)選(xuan)(xuan)擇某些組的(de)(de)(de)(de)(de)輸(shu)出交(jiao)流接觸器的(de)(de)(de)(de)(de)電(dian)(dian)流水(shui)平(ping)。基本上，電(dian)(dian)流水(shui)平(ping)是通過一個步驟選(xuan)(xuan)擇的(de)(de)(de)(de)(de)，該步驟會導致交(jiao)流接觸器在高(gao)溫天氣(qi)下運(yun)行期間燒斷(duan)。

根據電(dian)(dian)氣設(she)(she)備(bei)的(de)接(jie)線規定，接(jie)線盒可安裝在封閉(bi)或(huo)半(ban)封閉(bi)的(de)金屬外殼中(zhong)或(huo)屏幕上，以(yi)形(xing)成配電(dian)(dian)室設(she)(she)備(bei)。如(ru)果一切正(zheng)常，可以(yi)使用(yong)手或(huo)控制開關(guan)連接(jie)或(huo)斷開電(dian)(dian)源電(dian)(dian)路。常見的(de)錯誤(wu)或(huo)異常取決于家(jia)用(yong)電(dian)(dian)器的(de)維(wei)護，以(yi)斷開電(dian)(dian)路或(huo)警報。識(shi)別儀可以(yi)在信息模式下顯示(shi)各種主(zhu)要(yao)參數，還可以(yi)調整某些電(dian)(dian)氣設(she)(she)備(bei)的(de)主(zhu)要(yao)參數，并提(ti)醒(xing)或(huo)發出所有正(zheng)常工作設(she)(she)置(zhi)的(de)偏差信號。常用(yong)于發電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
