配電柜分動力配(pei)(pei)電(dian)(dian)(dian)柜(ju)(ju)和照明(ming)配(pei)(pei)電(dian)(dian)(dian)柜(ju)(ju)、計(ji)量箱，是(shi)配(pei)(pei)電(dian)(dian)(dian)系統(tong)的(de)末級設(she)備。配(pei)(pei)電(dian)(dian)(dian)柜(ju)(ju)是(shi)電(dian)(dian)(dian)動機控制中(zhong)(zhong)心的(de)統(tong)稱。配(pei)(pei)電(dian)(dian)(dian)柜(ju)(ju)使用在負(fu)荷(he)比較分散(san)、回路(lu)較少的(de)場(chang)合(he)；電(dian)(dian)(dian)動機控制中(zhong)(zhong)心用于負(fu)荷(he)集中(zhong)(zhong)、回路(lu)較多的(de)場(chang)合(he)。它們(men)把上配(pei)(pei)電(dian)(dian)(dian)設(she)備某一電(dian)(dian)(dian)路(lu)的(de)電(dian)(dian)(dian)能分配(pei)(pei)給就近的(de)負(fu)荷(he)。這級設(she)備應對(dui)負(fu)荷(he)提供保護、監(jian)視和控制。

配電(dian)(dian)板(ban)(箱)安裝(zhuang)要(yao)求(qiu)是：配電(dian)(dian)板(ban)(箱)應(ying)用(yong)不(bu)可(ke)燃(ran)材(cai)料制作(zuo)；觸(chu)電(dian)(dian)危險性(xing)小的生(sheng)產場所和辦公室，可(ke)安裝(zhuang)開(kai)啟式(shi)(shi)的配電(dian)(dian)板(ban)；在觸(chu)電(dian)(dian)危險性(xing)大或(huo)作(zuo)業環境較差的加工(gong)車間、鑄造、鍛造、熱處理、鍋爐房、木工(gong)房等場所，應(ying)安裝(zhuang)封(feng)閉式(shi)(shi)箱柜；在有導電(dian)(dian)性(xing)粉塵(chen)或(huo)產生(sheng)易燃(ran)易爆氣(qi)體(ti)的危險作(zuo)業場所，安裝(zhuang)密閉式(shi)(shi)或(huo)型的電(dian)(dian)氣(qi)設施；配電(dian)(dian)板(ban)(箱)各電(dian)(dian)氣(qi)元件、儀表(biao)、開(kai)關和線路應(ying)排列(lie)整齊，安裝(zhuang)牢固，操(cao)作(zuo)方便。落地安裝(zhuang)的板(ban)(箱)底面(mian)應(ying)高出(chu)地面(mian)5~10 mm；操(cao)作(zuo)手柄中(zhong)心高度一般為(wei)1.2～1.5m；板(ban)(箱)前方0.8～1.2m的范(fan)圍(wei)內無障礙物；保護(hu)線連接；板(ban)(箱)以外(wai)不(bu)得有裸(luo)帶電(dian)(dian)體(ti)外(wai)露(lu)；裝(zhuang)設在板(ban)(箱)外(wai)表(biao)面(mian)或(huo)配電(dian)(dian)板(ban)上(shang)的電(dian)(dian)氣(qi)元件，有的屏護(hu)。

智能配電(dian)(dian)(dian)柜(ju)實(shi)時(shi)監控各輸(shu)出(chu)分(fen)路(lu)的(de)(de)電(dian)(dian)(dian)流，并(bing)可(ke)設定各輸(shu)出(chu)分(fen)路(lu)電(dian)(dian)(dian)流異(yi)常的(de)(de)預告警值(zhi)，如16A開(kai)關，設定報警值(zhi)為14A，則負載超過14A就報警，可(ke)預先(xian)發現故障或人為操作隱患，避免過載時(shi)，開(kai)關切斷(duan)(duan)電(dian)(dian)(dian)源，造成整(zheng)個機(ji)柜(ju)設備(bei)斷(duan)(duan)電(dian)(dian)(dian)。另(ling)外(wai)輸(shu)出(chu)分(fen)路(lu)選用熱插拔斷(duan)(duan)路(lu)器，具備(bei)取電(dian)(dian)(dian)相位的(de)(de)調(diao)整(zheng)能力，輕松實(shi)現3相不平衡的(de)(de)靈(ling)活調(diao)整(zheng)，也可(ke)在(zai)不斷(duan)(duan)電(dian)(dian)(dian)的(de)(de)情況下，在(zai)線增加輸(shu)出(chu)分(fen)路(lu)，進行開(kai)關   換(huan)。
