大連配電箱指除安(an)裝(zhuang)面外，其它所有側面都被封閉(bi)起來的(de)一(yi)種低壓開(kai)關柜。這種柜子的(de)開(kai)關、保(bao)護(hu)和監測控制(zhi)等電(dian)氣元件，均安(an)裝(zhuang)在一(yi)個(ge)用鋼或絕緣(yuan)材料制(zhi)成的(de)封閉(bi)外殼(ke)內(nei)，可(ke)靠(kao)墻或離(li)墻安(an)裝(zhuang)。

    在(zai)(zai)(zai)大連配(pei)電(dian)(dian)(dian)(dian)箱箱式(shi)房(fang)的(de)(de)(de)(de)(de)應用中，配(pei)電(dian)(dian)(dian)(dian)箱的(de)(de)(de)(de)(de)安裝在(zai)(zai)(zai)很多時(shi)候都會用到(dao)，在(zai)(zai)(zai)安裝前，我(wo)們首先需要確認，我(wo)們在(zai)(zai)(zai)房(fang)屋上(shang)安裝的(de)(de)(de)(de)(de)配(pei)電(dian)(dian)(dian)(dian)箱是動(dong)(dong)力(li)配(pei)電(dian)(dian)(dian)(dian)箱還是普通(tong)照明(ming)(ming)配(pei)電(dian)(dian)(dian)(dian)箱，這個我(wo)們首先要確認清楚，若在(zai)(zai)(zai)房(fang)屋上(shang)安裝的(de)(de)(de)(de)(de)是普通(tong)照明(ming)(ming)配(pei)電(dian)(dian)(dian)(dian)箱，則可以直接(jie)(jie)裝在(zai)(zai)(zai)房(fang)子(zi)墻體(ti)上(shang)，若在(zai)(zai)(zai)箱式(shi)房(fang)上(shang)安裝的(de)(de)(de)(de)(de)是動(dong)(dong)力(li)配(pei)電(dian)(dian)(dian)(dian)箱的(de)(de)(de)(de)(de)話(hua)，需要再配(pei)電(dian)(dian)(dian)(dian)箱和房(fang)子(zi)之間加上(shang)絕緣墊，并(bing)且(qie)電(dian)(dian)(dian)(dian)箱和大地(di)(di)要有直接(jie)(jie)連接(jie)(jie)的(de)(de)(de)(de)(de)地(di)(di)線。

    大連(lian)配電(dian)(dian)箱發電(dian)(dian)機(ji)組啟動(dong)后(hou)，應利用動(dong)力(li)(li)屏(ping)升速(su)開(kai)關手動(dong)緩慢加(jia)速(su)，直到(dao)發電(dian)(dian)機(ji)進(jin)入(ru)(ru)正(zheng)常工作狀態(tai)(tai)，電(dian)(dian)壓與(yu)(yu)頻率(lv)達到(dao)規定(ding)(ding)值(zhi)，方可合閘送電(dian)(dian)。配電(dian)(dian)板進(jin)入(ru)(ru)配電(dian)(dian)狀態(tai)(tai)后(hou)，不(bu)得(de)隨意(yi)拔動(dong)動(dong)力(li)(li)屏(ping)升速(su)開(kai)關，空氣斷路(lu)器的(de)閉(bi)鎖開(kai)關非緊急情況不(bu)得(de)使用。發電(dian)(dian)機(ji)并聯運行(xing)要嚴格按照(zhao)并車(che)條件(jian)要求與(yu)(yu)規定(ding)(ding)進(jin)行(xing)操(cao)作，要注意(yi)出現(xian)逆功率(lv)（逆流(liu)）和(he)并車(che)失敗等現(xian)象。停(ting)機(ji)時(shi)應先(xian)切斷發電(dian)(dian)機(ji)負(fu)荷，然后(hou)空載停(ting)車(che)，不(bu)得(de)帶(dai)負(fu)荷直接停(ting)機(ji)。
