中(zhong)電(dian)(dian)氣(qi)設備選(xuan)(xuan)擇(ze)不(bu)當(dang)造成的(de)常見錯誤：生(sheng)產過(guo)程中(zhong)交流(liu)接(jie)觸器的(de)體(ti)(ti)積選(xuan)(xuan)擇(ze)不(bu)當(dang)，不(bu)同組的(de)插座控制(zhi)電(dian)(dian)路安裝了相同體(ti)(ti)積的(de)交流(liu)接(jie)觸器，三相負載的(de)差異不(bu)完全考慮(lv)過(guo)的(de)。在(zai)平(ping)衡狀態下，不(bu)能在(zai)所(suo)有正常模型中(zhong)選(xuan)(xuan)擇(ze)某些組的(de)輸出(chu)交流(liu)接(jie)觸器的(de)電(dian)(dian)流(liu)水(shui)平(ping)。基(ji)本(ben)上，電(dian)(dian)流(liu)水(shui)平(ping)是通過(guo)一(yi)個步(bu)驟選(xuan)(xuan)擇(ze)的(de)，該步(bu)驟會導致交流(liu)接(jie)觸器在(zai)高溫天氣(qi)下運行期間燒斷。

根據電(dian)(dian)(dian)(dian)氣設備的(de)(de)接(jie)線規定，接(jie)線盒(he)可安裝在(zai)封(feng)閉或半封(feng)閉的(de)(de)金屬(shu)外殼中或屏幕上，以形成配(pei)電(dian)(dian)(dian)(dian)室(shi)設備。如(ru)果一(yi)切正(zheng)常，可以使用手或控制開關(guan)連接(jie)或斷開電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)路。常見的(de)(de)錯誤或異(yi)常取決(jue)于(yu)家用電(dian)(dian)(dian)(dian)器的(de)(de)維(wei)護，以斷開電(dian)(dian)(dian)(dian)路或警報。識別儀可以在(zai)信息(xi)模式(shi)下顯(xian)示各種主要參(can)數，還可以調整某些電(dian)(dian)(dian)(dian)氣設備的(de)(de)主要參(can)數，并提(ti)醒或發出所有正(zheng)常工(gong)作(zuo)設置的(de)(de)偏(pian)差信號(hao)。常用于(yu)發電(dian)(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站。
