三(san)(san)相(xiang)(xiang)變(bian)(bian)(bian)(bian)單(dan)(dan)(dan)(dan)相(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)是把三(san)(san)相(xiang)(xiang)輸(shu)(shu)入(ru)變(bian)(bian)(bian)(bian)成一個單(dan)(dan)(dan)(dan)相(xiang)(xiang)輸(shu)(shu)出(chu)的(de)(de)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)。該變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)輸(shu)(shu)入(ru)最大一相(xiang)(xiang)電(dian)(dian)流(liu)(liu)(liu)(liu)是另(ling)外其中(zhong)一相(xiang)(xiang)電(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)2倍。它(ta)能(neng)(neng)使單(dan)(dan)(dan)(dan)相(xiang)(xiang)220V負(fu)載電(dian)(dian)流(liu)(liu)(liu)(liu)降低(di)40%；單(dan)(dan)(dan)(dan)相(xiang)(xiang)380V負(fu)載電(dian)(dian)流(liu)(liu)(liu)(liu)最大一相(xiang)(xiang)電(dian)(dian)流(liu)(liu)(liu)(liu)與之相(xiang)(xiang)同，而另(ling)外兩相(xiang)(xiang)是最大一相(xiang)(xiang)電(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)50%。它(ta)比(bi)隔離變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)成本高。它(ta)被廣泛用于(yu)工礦企業特定負(fu)載的(de)(de)場合(he)中(zhong)，解決三(san)(san)相(xiang)(xiang)電(dian)(dian)流(liu)(liu)(liu)(liu)嚴重不平衡的(de)(de)問題。 三(san)(san)相(xiang)(xiang)變(bian)(bian)(bian)(bian)單(dan)(dan)(dan)(dan)相(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)本系列產(chan)品適用于(yu)交流(liu)(liu)(liu)(liu)50/60Hz工作電(dian)(dian)壓(ya)(ya)600V以下。該系列變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)絕緣耐熱(re)等級為F級。 三(san)(san)相(xiang)(xiang)變(bian)(bian)(bian)(bian)單(dan)(dan)(dan)(dan)相(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)鐵心為冷軋取向優質(zhi)硅鋼(gang)片迭(die)積(ji)而成，線圈結構(gou)采用圓筒、橢圓筒和矩形筒式(shi)。體積(ji)小，性能(neng)(neng)優，安全可靠。
