高壓軟起動柜精心設計，考慮各種要求，以保障各種使用對象和使用場合。高壓固態軟啟動柜價格,高壓軟啟動柜廠家分享結構采用GB11022-1999-T高(gao)壓(ya)開(kai)關設(she)(she)備(bei)，和控(kong)制設(she)(she)備(bei)的共(gong)用技術要求(qiu)，在柜(ju)體中(zhong)應用密封處理，減少對機(ji)器(qi)內部的污染，布局合理。數字觸(chu)發系統將低壓(ya)控(kong)制通，過(guo)光纖連接到高(gao)壓(ya)部分，便捷的維修(xiu)設(she)(she)計允許各相模(mo)塊可(ke)以迅(xun)速單(dan)獨(du)進行(xing)更(geng)換。為運行(xing)安(an)全(quan)起見，高(gao)壓(ya)部分和低壓(ya)部分完全(quan)隔(ge)離開(kai)來。   

 主要由可(ke)控(kong)(kong)硅(gui)串(chuan)并(bing)聯和(he)旁路接觸器組成(cheng)。SCR電(dian)源器件，在(zai)每(mei)相(xiang)中是用一對(dui)相(xiang)同參數(shu)的(de)(de)，SCR反相(xiang)平行(xing)的(de)(de)安(an)裝(zhuang)在(zai)一組的(de)(de)。為了達到所有使(shi)用電(dian)網的(de)(de)峰值(zhi)，電(dian)壓(ya)(ya)要求,對(dui)SCR進行(xing)串(chuan)聯。通過控(kong)(kong)制可(ke)控(kong)(kong)硅(gui)的(de)(de)開關以實(shi)現對(dui)交流三相(xiang)電(dian)源進行(xing)斬波，控(kong)(kong)制輸出電(dian)壓(ya)(ya)的(de)(de)幅值(zhi)，并(bing)在(zai)啟動過程完成(cheng)后，將(jiang)高壓(ya)(ya)電(dian)機軟啟動裝(zhuang)置，切換到旁路狀(zhuang)態。
