中電(dian)(dian)氣設(she)備選擇(ze)不(bu)(bu)當(dang)造(zao)成的(de)(de)(de)常(chang)見錯誤：生產過(guo)程中交(jiao)流(liu)接觸器(qi)的(de)(de)(de)體積選擇(ze)不(bu)(bu)當(dang)，不(bu)(bu)同組的(de)(de)(de)插座控制電(dian)(dian)路(lu)安裝了相同體積的(de)(de)(de)交(jiao)流(liu)接觸器(qi)，三相負載的(de)(de)(de)差(cha)異(yi)不(bu)(bu)完全考(kao)慮過(guo)的(de)(de)(de)。在平(ping)衡狀態下，不(bu)(bu)能在所有正常(chang)模型(xing)中選擇(ze)某些(xie)組的(de)(de)(de)輸出交(jiao)流(liu)接觸器(qi)的(de)(de)(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(tong)過(guo)一個步(bu)驟(zou)選擇(ze)的(de)(de)(de)，該步(bu)驟(zou)會導(dao)致交(jiao)流(liu)接觸器(qi)在高溫天氣下運行期間燒斷(duan)。

根(gen)據電(dian)(dian)(dian)(dian)氣設(she)備的接線(xian)規定，接線(xian)盒(he)可安(an)裝在封(feng)閉或半(ban)封(feng)閉的金屬外(wai)殼中或屏幕上，以(yi)(yi)形成配(pei)電(dian)(dian)(dian)(dian)室設(she)備。如果一切正常，可以(yi)(yi)使用(yong)手(shou)或控(kong)制開(kai)關連(lian)接或斷(duan)開(kai)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路。常見的錯誤或異常取決于(yu)家用(yong)電(dian)(dian)(dian)(dian)器的維護，以(yi)(yi)斷(duan)開(kai)電(dian)(dian)(dian)(dian)路或警(jing)報。識別(bie)儀可以(yi)(yi)在信息模(mo)式下顯示各種主(zhu)要參數，還可以(yi)(yi)調整某(mou)些電(dian)(dian)(dian)(dian)氣設(she)備的主(zhu)要參數，并提醒或發出所(suo)有正常工作設(she)置(zhi)的偏差信號(hao)。常用(yong)于(yu)發電(dian)(dian)(dian)(dian)，配(pei)電(dian)(dian)(dian)(dian)和變電(dian)(dian)(dian)(dian)站(zhan)。
