大連高低壓配電柜、大連配電箱技術無論是產(chan)品設計、制造工藝，還(huan)是經營管理，生產(chan)過(guo)程方面都取得了(le)很(hen)大進步。

低(di)壓(ya)(ya)配電(dian)(dian)(dian)柜(ju)電(dian)(dian)(dian)器(qi)(qi)行業(ye)則先于高(gao)壓(ya)(ya)行業(ye)將計算機(ji)(ji)技(ji)術(shu)(shu)應用(yong)(yong)與產品(pin)結構中。實(shi)現(xian)產品(pin)智能化和(he)網絡化，并已(yi)(yi)(yi)(yi)有智能的(de)低(di)壓(ya)(ya)斷路器(qi)(qi)、電(dian)(dian)(dian)動機(ji)(ji)控(kong)制(zhi)器(qi)(qi)、過(guo)載繼電(dian)(dian)(dian)器(qi)(qi)、大連開(kai)(kai)關(guan)柜(ju)等(deng)產品(pin)問(wen)世;此外，國內低(di)壓(ya)(ya)電(dian)(dian)(dian)器(qi)(qi)在(zai)可靠(kao)性(xing)研(yan)究、無觸點開(kai)(kai)關(guan)、真空技(ji)術(shu)(shu)、限流技(ji)術(shu)(shu)、零(ling)飛弧(hu)(hu)、高(gao)性(xing)能和(he)小型化、組(zu)合化、模(mo)數化、模(mo)塊(kuai)化等(deng)方(fang)(fang)面均取得了(le)可喜的(de)成(cheng)績。我(wo)國高(gao)壓(ya)(ya)開(kai)(kai)關(guan)柜(ju)已(yi)(yi)(yi)(yi)發展到(dao)金屬封閉(bi)型(含鎧(kai)裝(zhuang)、間(jian)隔(ge)和(he)箱(xiang)式(shi)(shi)(shi))、低(di)壓(ya)(ya)則以(yi)封閉(bi)抽出式(shi)(shi)(shi)單元為主。各種高(gao)壓(ya)(ya)手車(che)式(shi)(shi)(shi)、中置式(shi)(shi)(shi)、環網柜(ju)、F-C柜(ju)、箱(xiang)變以(yi)及低(di)壓(ya)(ya)抽屜柜(ju)、電(dian)(dian)(dian)動機(ji)(ji)控(kong)制(zhi)中心等(deng)產品(pin)已(yi)(yi)(yi)(yi)大量上市(shi)。我(wo)國高(gao)低(di)壓(ya)(ya)成(cheng)套設備均已(yi)(yi)(yi)(yi)等(deng)同或等(deng)效采(cai)用(yong)(yong)IEC標準(zhun)，根據國情在(zai)絕緣要求上還嚴于IEC標準(zhun)。我(wo)國電(dian)(dian)(dian)器(qi)(qi)行業(ye)中不少企(qi)業(ye)已(yi)(yi)(yi)(yi)開(kai)(kai)始采(cai)用(yong)(yong)CAD、CAPP、CAM、CAE、MIS等(deng)先進技(ji)術(shu)(shu)，部分重(zhong)點，骨干企(qi)業(ye)已(yi)(yi)(yi)(yi)具備CIMS技(ji)術(shu)(shu)。值得一(yi)提(ti)的(de)是(shi)(shi)，直到(dao)二十世紀結束(shu)，無論(lun)是(shi)(shi)國內還是(shi)(shi)國外，整個電(dian)(dian)(dian)器(qi)(qi)科(ke)學理(li)論(lun)尚(shang)未達到(dao)成(cheng)熟和(he)完善(shan)的(de)地(di)步，特別是(shi)(shi)對電(dian)(dian)(dian)弧(hu)(hu)過(guo)程(cheng)及其數學模(mo)型的(de)建立(li)等(deng)課題，仍然有待進一(yi)步研(yan)究。電(dian)(dian)(dian)器(qi)(qi)產品(pin)的(de)設計除(chu)發熱、電(dian)(dian)(dian)動力、電(dian)(dian)(dian)接觸、電(dian)(dian)(dian)磁特性(xing)等(deng)方(fang)(fang)面有一(yi)些零(ling)星的(de)經驗公式(shi)(shi)(shi)外，說到(dao)底不過(guo)是(shi)(shi)類比優(you)化加實(shi)驗的(de)方(fang)(fang)法。
