中(zhong)電(dian)氣(qi)設備(bei)選(xuan)擇不當造成的(de)(de)常見(jian)錯誤：生產過程中(zhong)交(jiao)流(liu)(liu)接(jie)(jie)觸器(qi)的(de)(de)體(ti)(ti)積選(xuan)擇不當，不同(tong)組的(de)(de)插座控制電(dian)路安裝了相(xiang)同(tong)體(ti)(ti)積的(de)(de)交(jiao)流(liu)(liu)接(jie)(jie)觸器(qi)，三相(xiang)負載的(de)(de)差異不完(wan)全考慮過的(de)(de)。在平衡狀態下，不能(neng)在所有正常模型(xing)中(zhong)選(xuan)擇某(mou)些組的(de)(de)輸出交(jiao)流(liu)(liu)接(jie)(jie)觸器(qi)的(de)(de)電(dian)流(liu)(liu)水(shui)平。基本上(shang)，電(dian)流(liu)(liu)水(shui)平是通過一個(ge)步驟(zou)選(xuan)擇的(de)(de)，該步驟(zou)會導致交(jiao)流(liu)(liu)接(jie)(jie)觸器(qi)在高溫天氣(qi)下運行期(qi)間(jian)燒斷。

根據電(dian)(dian)(dian)氣設(she)備的(de)接(jie)線規定(ding)，接(jie)線盒可(ke)安裝在(zai)封閉或半封閉的(de)金(jin)屬外(wai)殼(ke)中或屏幕上，以(yi)形(xing)成配電(dian)(dian)(dian)室設(she)備。如果(guo)一切正常，可(ke)以(yi)使用手或控制開關連接(jie)或斷開電(dian)(dian)(dian)源電(dian)(dian)(dian)路。常見的(de)錯誤或異(yi)常取決于家用電(dian)(dian)(dian)器(qi)的(de)維護，以(yi)斷開電(dian)(dian)(dian)路或警(jing)報。識別(bie)儀可(ke)以(yi)在(zai)信息模式(shi)下(xia)顯示各種主(zhu)(zhu)要(yao)參數，還可(ke)以(yi)調整(zheng)某(mou)些電(dian)(dian)(dian)氣設(she)備的(de)主(zhu)(zhu)要(yao)參數，并提醒或發(fa)出所有(you)正常工作設(she)置的(de)偏(pian)差信號。常用于發(fa)電(dian)(dian)(dian)，配電(dian)(dian)(dian)和變電(dian)(dian)(dian)站。
