非晶(jing)合金變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)兼(jian)具了節能性(xing)和經(jing)濟性(xing)，其(qi)顯(xian)著特點是(shi)空載(zai)(zai)損(sun)耗(hao)很(hen)低，僅為S9系(xi)(xi)列油(you)浸式(shi)(shi)(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)20%左右，220v小型變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)，符合國家(jia)產業政策(ce)和電網(wang)節能降耗(hao)的(de)要求。節能型油(you)浸式(shi)(shi)(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)：油(you)浸式(shi)(shi)(shi)配(pei)電變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)按損(sun)耗(hao)性(xing)能分(fen)為S9、S11、S13系(xi)(xi)列，相比(bi)之下S11系(xi)(xi)列變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)空載(zai)(zai)損(sun)耗(hao)比(bi)S9系(xi)(xi)列低20%，S13系(xi)(xi)列變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)空載(zai)(zai)損(sun)耗(hao)比(bi)S11系(xi)(xi)列低25%。電力變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)是(shi)常(chang)見的(de)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)之一，它的(de)冷卻方式(shi)(shi)(shi)并(bing)不單一。它常(chang)用的(de)冷卻方式(shi)(shi)(shi)一般分(fen)為三種：油(you)浸自(zi)冷式(shi)(shi)(shi)、油(you)浸風冷式(shi)(shi)(shi)、強迫油(you)循環。

變(bian)(bian)壓(ya)(ya)器(qi)是利用(yong)電(dian)磁感應原(yuan)(yuan)理制(zhi)成(cheng)的(de)靜止用(yong)電(dian)器(qi)。當變(bian)(bian)壓(ya)(ya)器(qi)的(de)原(yuan)(yuan)線(xian)圈接在交流電(dian)源上時，鐵心(xin)中(zhong)便產生(sheng)交變(bian)(bian)磁通，交變(bian)(bian)磁通用(yong)φ表示。原(yuan)(yuan)、副線(xian)圈中(zhong)的(de)φ是相同(tong)的(de)。三(san)相隔(ge)離變(bian)(bian)壓(ya)(ya)器(qi)采(cai)用(yong)三(san)相雙(shuang)繞組(zu)結構，具有(you)防雷擊、防干擾特性。原(yuan)(yuan)副邊每個繞組(zu)分(fen)成(cheng)兩個線(xian)圈，該(gai)兩個線(xian)圈是用(yong)兩層互相絕(jue)緣的(de)金屬箔并繞起來的(de)。與變(bian)(bian)壓(ya)(ya)器(qi)相關的(de)一(yi)些主要的(de)技術參數包括(kuo)：額定(ding)容量：指(zhi)額定(ding)工作條件下變(bian)(bian)壓(ya)(ya)器(qi)的(de)額定(ding)輸出(chu)能力(li)（等于U×I，單位為kVA）。

變壓(ya)器(qi)(qi)由鐵(tie)芯（或磁(ci)芯）和線(xian)(xian)(xian)(xian)圈(quan)(quan)組(zu)成(cheng)，線(xian)(xian)(xian)(xian)圈(quan)(quan)有兩個(ge)(ge)或兩個(ge)(ge)以(yi)上的(de)繞(rao)組(zu)，其中接電(dian)(dian)源(yuan)(yuan)的(de)繞(rao)組(zu)叫初級(ji)線(xian)(xian)(xian)(xian)圈(quan)(quan)，其余(yu)的(de)繞(rao)組(zu)叫次級(ji)線(xian)(xian)(xian)(xian)圈(quan)(quan)。變壓(ya)器(qi)(qi)是(shi)利用(yong)(yong)電(dian)(dian)磁(ci)感應原(yuan)理制成(cheng)的(de)靜止用(yong)(yong)電(dian)(dian)器(qi)(qi)。當變壓(ya)器(qi)(qi)的(de)原(yuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)接在交(jiao)(jiao)流電(dian)(dian)源(yuan)(yuan)上時，鐵(tie)心中便產生交(jiao)(jiao)變磁(ci)通，交(jiao)(jiao)變磁(ci)通用(yong)(yong)φ表示。原(yuan)、副(fu)線(xian)(xian)(xian)(xian)圈(quan)(quan)中的(de)φ是(shi)相同的(de)。未來幾年，電(dian)(dian)網(wang)建設(she)和城鄉(xiang)配電(dian)(dian)網(wang)改造(zao)仍是(shi)我(wo)國(guo)電(dian)(dian)力工業的(de)首要任務，配電(dian)(dian)變壓(ya)器(qi)(qi)的(de)市場需(xu)求量有望保(bao)持較(jiao)強勁的(de)增漲。
