產品概述：
SZ11系列疊鐵心有(you)載(zai)調(diao)壓(ya)油浸式(shi)變壓(ya)器，是在S11系列立體卷鐵心油浸式(shi)變壓(ya)器的基礎_上開(kai)發出的升級產品。
可(ke)在帶負荷的情況下自動(dong)或(huo)手動(dong)對有載開(kai)關(guan)進行操作，實現(xian)(xian)調(diao)壓(ya)，還可(ke)以通過(guo)控(kong)制器實現(xian)(xian)遠距離調(diao)壓(ya)控(kong)制。
產品(pin)適用于電網電壓波動較大、而(er)對電壓要求較穩定(ding)的用戶。
主要意義：
由于電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)波動的(de)(de)變(bian)(bian)(bian)動以及(ji)負載的(de)(de)變(bian)(bian)(bian)化，將(jiang)導致運行中變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)輸出電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)波動。電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)太高或太低(di)都會(hui)使用電(dian)(dian)(dian)設備(bei)不能正常工作，甚至(zhi)將(jiang)造(zao)成設備(bei)燒毀(hui)，同時也影響變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)自身絕緣和效率。因此(ci)，變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)動范(fan)圍(wei):配電(dian)(dian)(dian)變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)一般不超過額定電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)2x士5%，系統(tong)電(dian)(dian)(dian)網(wang)中的(de)(de)主變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)不超過額定電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)2x士2.5%，為了保障電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)在合理范(fan)圍(wei)內變(bian)(bian)(bian)動，就必須進行電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)調壓(ya)(ya)(ya)(ya)(ya)。
