中(zhong)電(dian)(dian)(dian)氣設備選擇不當造成(cheng)的(de)常(chang)見錯誤：生產過程中(zhong)交(jiao)流(liu)(liu)(liu)接(jie)觸器(qi)(qi)的(de)體積(ji)選擇不當，不同組(zu)(zu)的(de)插座控制電(dian)(dian)(dian)路(lu)安裝了(le)相同體積(ji)的(de)交(jiao)流(liu)(liu)(liu)接(jie)觸器(qi)(qi)，三(san)相負載(zai)的(de)差(cha)異(yi)不完全考慮過的(de)。在平衡(heng)狀態下，不能在所(suo)有(you)正常(chang)模型中(zhong)選擇某(mou)些組(zu)(zu)的(de)輸出交(jiao)流(liu)(liu)(liu)接(jie)觸器(qi)(qi)的(de)電(dian)(dian)(dian)流(liu)(liu)(liu)水平。基本上(shang)，電(dian)(dian)(dian)流(liu)(liu)(liu)水平是通過一個步(bu)驟選擇的(de)，該(gai)步(bu)驟會導(dao)致交(jiao)流(liu)(liu)(liu)接(jie)觸器(qi)(qi)在高(gao)溫天氣下運行期間燒斷。

根據電氣設(she)備的(de)接線規(gui)定，接線盒可(ke)安裝在(zai)封閉(bi)或(huo)(huo)(huo)半(ban)封閉(bi)的(de)金屬外殼(ke)中或(huo)(huo)(huo)屏幕上，以(yi)形成配電室(shi)設(she)備。如果一切正常，可(ke)以(yi)使用手或(huo)(huo)(huo)控制(zhi)開關(guan)連接或(huo)(huo)(huo)斷(duan)開電源電路(lu)。常見的(de)錯誤或(huo)(huo)(huo)異常取決(jue)于家用電器的(de)維(wei)護，以(yi)斷(duan)開電路(lu)或(huo)(huo)(huo)警報。識別儀(yi)可(ke)以(yi)在(zai)信息模式(shi)下(xia)顯示各種主要(yao)參數，還可(ke)以(yi)調整某些電氣設(she)備的(de)主要(yao)參數，并提醒或(huo)(huo)(huo)發出所有正常工(gong)作設(she)置的(de)偏差信號(hao)。常用于發電，配電和變(bian)電站。
