大連配電箱是使(shi)(shi)用(yong)在負(fu)荷(he)比較(jiao)分散、回路較(jiao)少的場合；電動機控制中(zhong)心是使(shi)(shi)用(yong)于負(fu)荷(he)集中(zhong)、回路較(jiao)多(duo)的場合。 

    大連配(pei)電(dian)箱(xiang)(xiang)應有(you)(you)齊備的(de)中(zhong)性線按線端(duan)子(zi)，箱(xiang)(xiang)體必須具有(you)(you)牢固可靠的(de)保護接(jie)地接(jie)線端(duan)子(zi)。按照規范要求：導線與(yu)電(dian)氣(qi)元件連接(jie)必須配(pei)有(you)(you)彈墊圈并(bing)壓按牢固。 配(pei)電(dian)柜(ju)是(shi)電(dian)動機控制中(zhong)心(xin)的(de)統稱。配(pei)電(dian)柜(ju)是(shi)使(shi)用(yong)在負荷比(bi)較分散、回路較少的(de)場合；電(dian)動機控制中(zhong)心(xin)是(shi)使(shi)用(yong)于負荷集中(zhong)、回路較多的(de)場合。
