大連高低壓配電柜、大連配電箱技術無論是產品(pin)設(she)計、制造工藝，還是經(jing)營管理(li)，生產過程(cheng)方面都(dou)取得了很大(da)進步。

低(di)壓(ya)(ya)配電(dian)(dian)柜(ju)電(dian)(dian)器行業(ye)(ye)(ye)則先于高壓(ya)(ya)行業(ye)(ye)(ye)將計算機(ji)(ji)技術應用(yong)(yong)與產(chan)品(pin)(pin)結(jie)(jie)構中。實(shi)現產(chan)品(pin)(pin)智能(neng)化(hua)(hua)和網(wang)絡(luo)化(hua)(hua)，并(bing)已有智能(neng)的(de)(de)低(di)壓(ya)(ya)斷路器、電(dian)(dian)動(dong)(dong)機(ji)(ji)控制(zhi)器、過(guo)(guo)載繼電(dian)(dian)器、大(da)連開關(guan)(guan)柜(ju)等(deng)(deng)產(chan)品(pin)(pin)問(wen)世;此外(wai)(wai)，國(guo)(guo)內(nei)低(di)壓(ya)(ya)電(dian)(dian)器在可(ke)靠性研究(jiu)、無(wu)觸(chu)點開關(guan)(guan)、真空技術、限流技術、零飛(fei)弧、高性能(neng)和小型(xing)(xing)化(hua)(hua)、組合化(hua)(hua)、模(mo)(mo)數化(hua)(hua)、模(mo)(mo)塊化(hua)(hua)等(deng)(deng)方(fang)面均取得了可(ke)喜的(de)(de)成績。我(wo)(wo)國(guo)(guo)高壓(ya)(ya)開關(guan)(guan)柜(ju)已發展到金屬封閉型(xing)(xing)(含(han)鎧(kai)裝、間(jian)隔和箱式(shi)(shi)(shi))、低(di)壓(ya)(ya)則以封閉抽(chou)出式(shi)(shi)(shi)單元為(wei)主。各(ge)種高壓(ya)(ya)手車式(shi)(shi)(shi)、中置式(shi)(shi)(shi)、環網(wang)柜(ju)、F-C柜(ju)、箱變以及低(di)壓(ya)(ya)抽(chou)屜柜(ju)、電(dian)(dian)動(dong)(dong)機(ji)(ji)控制(zhi)中心等(deng)(deng)產(chan)品(pin)(pin)已大(da)量(liang)上市(shi)。我(wo)(wo)國(guo)(guo)高低(di)壓(ya)(ya)成套設(she)備均已等(deng)(deng)同或(huo)等(deng)(deng)效采用(yong)(yong)IEC標準，根據國(guo)(guo)情(qing)在絕(jue)緣要求上還(huan)嚴于IEC標準。我(wo)(wo)國(guo)(guo)電(dian)(dian)器行業(ye)(ye)(ye)中不少企業(ye)(ye)(ye)已開始采用(yong)(yong)CAD、CAPP、CAM、CAE、MIS等(deng)(deng)先進技術，部分重點，骨干企業(ye)(ye)(ye)已具備CIMS技術。值得一(yi)提的(de)(de)是(shi)(shi)，直到二(er)十世紀(ji)結(jie)(jie)束，無(wu)論(lun)是(shi)(shi)國(guo)(guo)內(nei)還(huan)是(shi)(shi)國(guo)(guo)外(wai)(wai)，整(zheng)個電(dian)(dian)器科學理論(lun)尚未達到成熟(shu)和完善的(de)(de)地(di)步(bu)，特別是(shi)(shi)對電(dian)(dian)弧過(guo)(guo)程及其數學模(mo)(mo)型(xing)(xing)的(de)(de)建立等(deng)(deng)課題(ti)，仍(reng)然有待進一(yi)步(bu)研究(jiu)。電(dian)(dian)器產(chan)品(pin)(pin)的(de)(de)設(she)計除(chu)發熱、電(dian)(dian)動(dong)(dong)力、電(dian)(dian)接觸(chu)、電(dian)(dian)磁特性等(deng)(deng)方(fang)面有一(yi)些零星(xing)的(de)(de)經驗公式(shi)(shi)(shi)外(wai)(wai)，說到底(di)不過(guo)(guo)是(shi)(shi)類比優化(hua)(hua)加實(shi)驗的(de)(de)方(fang)法。
