中電氣設(she)備選(xuan)(xuan)擇不(bu)當造成(cheng)的(de)(de)常見(jian)錯誤：生產過程中交(jiao)流接(jie)觸器的(de)(de)體積選(xuan)(xuan)擇不(bu)當，不(bu)同(tong)組(zu)的(de)(de)插(cha)座控制電路安裝了相同(tong)體積的(de)(de)交(jiao)流接(jie)觸器，三相負載的(de)(de)差異不(bu)完全(quan)考慮(lv)過的(de)(de)。在平(ping)(ping)衡狀態下，不(bu)能在所有正(zheng)常模(mo)型中選(xuan)(xuan)擇某些(xie)組(zu)的(de)(de)輸出交(jiao)流接(jie)觸器的(de)(de)電流水(shui)(shui)平(ping)(ping)。基(ji)本上，電流水(shui)(shui)平(ping)(ping)是(shi)通過一個步驟選(xuan)(xuan)擇的(de)(de)，該(gai)步驟會(hui)導致交(jiao)流接(jie)觸器在高溫天(tian)氣下運(yun)行期間(jian)燒斷。

根據電(dian)(dian)氣(qi)設(she)(she)(she)備的接(jie)(jie)線(xian)規定，接(jie)(jie)線(xian)盒(he)可(ke)安(an)裝(zhuang)在封閉(bi)或(huo)半封閉(bi)的金屬外殼中(zhong)或(huo)屏幕上，以(yi)(yi)形成配電(dian)(dian)室設(she)(she)(she)備。如果一切正常，可(ke)以(yi)(yi)使用(yong)手(shou)或(huo)控制開關連(lian)接(jie)(jie)或(huo)斷開電(dian)(dian)源電(dian)(dian)路。常見的錯(cuo)誤或(huo)異(yi)常取(qu)決于家用(yong)電(dian)(dian)器的維護，以(yi)(yi)斷開電(dian)(dian)路或(huo)警報。識別儀可(ke)以(yi)(yi)在信息(xi)模式下顯示各種主(zhu)要參數(shu)(shu)，還(huan)可(ke)以(yi)(yi)調整某(mou)些(xie)電(dian)(dian)氣(qi)設(she)(she)(she)備的主(zhu)要參數(shu)(shu)，并提醒或(huo)發(fa)出所有(you)正常工作設(she)(she)(she)置(zhi)的偏差信號。常用(yong)于發(fa)電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
