產品描述

　　(1)一級(ji)(ji)(ji)配(pei)電設(she)備，統稱(cheng)為動力(li)配(pei)電中心。它們集中安(an)裝在企業的變(bian)電站，把(ba)電能分配(pei)給不同地點的下級(ji)(ji)(ji)配(pei)電設(she)備。這一級(ji)(ji)(ji)設(she)備緊靠降壓(ya)(ya)變(bian)壓(ya)(ya)器，故電氣(qi)參數要求較(jiao)高，輸出電路(lu)容量也較(jiao)大。

　　(2)二(er)級配電(dian)(dian)設備(bei)，是動力配電(dian)(dian)柜(ju)和電(dian)(dian)動機(ji)控(kong)(kong)制中(zhong)心的(de)統稱。動力配電(dian)(dian)柜(ju)使用在負荷比(bi)較分散、回路(lu)較少的(de)場(chang)合;電(dian)(dian)動機(ji)控(kong)(kong)制中(zhong)心用于負荷集中(zhong)、回路(lu)較多的(de)場(chang)合。它(ta)們把(ba)上(shang)一(yi)級配電(dian)(dian)設備(bei)某一(yi)電(dian)(dian)路(lu)的(de)電(dian)(dian)能分配給就(jiu)近的(de)負荷。這級設備(bei)應對(dui)負荷提(ti)供保護、監(jian)視和控(kong)(kong)制。

　　(3)末級(ji)配(pei)電(dian)(dian)(dian)設備總稱(cheng)為(wei)照明動(dong)力配(pei)電(dian)(dian)(dian)箱。它們遠(yuan)離供電(dian)(dian)(dian)中心，是(shi)分(fen)散的小容量(liang)配(pei)電(dian)(dian)(dian)設備

　　配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)柜微(wei)機保(bao)護(hu)裝(zhuang)置是由(you)高(gao)集成度、總線并出(chu)芯片單片機、高(gao)精(jing)度電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓互感器、高(gao)絕緣強度出(chu)口中(zhong)間繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器、高(gao)可靠開關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源模塊等(deng)部件組成。開關柜微(wei)機保(bao)護(hu)裝(zhuang)置主要作為110KV及以下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓等(deng)級的(de)開關柜。發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)廠、變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)、配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)等(deng)，也可作為部分70V-220V之間電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓等(deng)級開關柜中(zhong)系統的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)保(bao)護(hu)及測控。
