大連高低壓配電柜、大連配電箱技術(shu)無論(lun)是產品設計(ji)、制造工藝，還是經營管理，生產過程方面都取(qu)得了很大進步。

低壓(ya)(ya)(ya)配(pei)電(dian)(dian)(dian)柜(ju)(ju)電(dian)(dian)(dian)器(qi)(qi)行(xing)業(ye)則(ze)先(xian)于高壓(ya)(ya)(ya)行(xing)業(ye)將計(ji)算(suan)機(ji)(ji)技術應用與產(chan)品(pin)結構中(zhong)。實現產(chan)品(pin)智(zhi)能(neng)化(hua)和網絡化(hua)，并已(yi)有(you)智(zhi)能(neng)的(de)(de)低壓(ya)(ya)(ya)斷路器(qi)(qi)、電(dian)(dian)(dian)動(dong)機(ji)(ji)控制器(qi)(qi)、過(guo)載繼電(dian)(dian)(dian)器(qi)(qi)、大連開關(guan)(guan)柜(ju)(ju)等(deng)(deng)(deng)(deng)產(chan)品(pin)問世(shi);此外(wai)，國內低壓(ya)(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)在可靠性研究、無(wu)觸(chu)點開關(guan)(guan)、真空(kong)技術、限流(liu)技術、零飛弧、高性能(neng)和小型(xing)(xing)化(hua)、組(zu)合化(hua)、模(mo)數化(hua)、模(mo)塊化(hua)等(deng)(deng)(deng)(deng)方(fang)面均(jun)取得(de)了可喜的(de)(de)成績。我(wo)國高壓(ya)(ya)(ya)開關(guan)(guan)柜(ju)(ju)已(yi)發展到(dao)(dao)金屬封(feng)閉(bi)(bi)型(xing)(xing)(含(han)鎧裝、間隔和箱式(shi)(shi))、低壓(ya)(ya)(ya)則(ze)以封(feng)閉(bi)(bi)抽出式(shi)(shi)單元為主。各種(zhong)高壓(ya)(ya)(ya)手(shou)車式(shi)(shi)、中(zhong)置式(shi)(shi)、環網柜(ju)(ju)、F-C柜(ju)(ju)、箱變以及低壓(ya)(ya)(ya)抽屜柜(ju)(ju)、電(dian)(dian)(dian)動(dong)機(ji)(ji)控制中(zhong)心等(deng)(deng)(deng)(deng)產(chan)品(pin)已(yi)大量上市(shi)。我(wo)國高低壓(ya)(ya)(ya)成套設(she)備均(jun)已(yi)等(deng)(deng)(deng)(deng)同或等(deng)(deng)(deng)(deng)效采用IEC標準，根據國情(qing)在絕(jue)緣要求(qiu)上還嚴于IEC標準。我(wo)國電(dian)(dian)(dian)器(qi)(qi)行(xing)業(ye)中(zhong)不少企(qi)業(ye)已(yi)開始采用CAD、CAPP、CAM、CAE、MIS等(deng)(deng)(deng)(deng)先(xian)進技術，部分重點，骨干企(qi)業(ye)已(yi)具備CIMS技術。值得(de)一提(ti)的(de)(de)是(shi)，直到(dao)(dao)二十世(shi)紀結束，無(wu)論是(shi)國內還是(shi)國外(wai)，整個電(dian)(dian)(dian)器(qi)(qi)科學(xue)理(li)論尚未(wei)達(da)到(dao)(dao)成熟(shu)和完善的(de)(de)地步，特(te)別(bie)是(shi)對(dui)電(dian)(dian)(dian)弧過(guo)程及其數學(xue)模(mo)型(xing)(xing)的(de)(de)建立等(deng)(deng)(deng)(deng)課題，仍然(ran)有(you)待進一步研究。電(dian)(dian)(dian)器(qi)(qi)產(chan)品(pin)的(de)(de)設(she)計(ji)除發熱、電(dian)(dian)(dian)動(dong)力、電(dian)(dian)(dian)接觸(chu)、電(dian)(dian)(dian)磁特(te)性等(deng)(deng)(deng)(deng)方(fang)面有(you)一些零星的(de)(de)經驗公式(shi)(shi)外(wai)，說到(dao)(dao)底(di)不過(guo)是(shi)類(lei)比優化(hua)加(jia)實驗的(de)(de)方(fang)法。
