变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)是一(yi)(yi)种电(dian)(dian)(dian)(dian)力设(she)备(bei)(bei)，主要用(yong)于改变(bian)(bian)交(jiao)流(liu)电(dian)(dian)(dian)(dian)的(de)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)和(he)电(dian)(dian)(dian)(dian)流(liu)大小。它(ta)由两个(ge)(ge)或更多的(de)线圈(quan)(quan)（称(cheng)为(wei)原(yuan)(yuan)线圈(quan)(quan)和(he)次(ci)级(ji)线圈(quan)(quan)）组(zu)成，它(ta)们(men)通过一(yi)(yi)个(ge)(ge)铁芯相连。当原(yuan)(yuan)线圈(quan)(quan)中通电(dian)(dian)(dian)(dian)时(shi)，它(ta)会(hui)产(chan)生一(yi)(yi)个(ge)(ge)磁(ci)场(chang)，这个(ge)(ge)磁(ci)场(chang)会(hui)在铁芯中感应(ying)出一(yi)(yi)个(ge)(ge)电(dian)(dian)(dian)(dian)流(liu)，从(cong)而使次(ci)级(ji)线圈(quan)(quan)中也产(chan)生电(dian)(dian)(dian)(dian)流(liu)。变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)的(de)工作(zuo)原(yuan)(yuan)理基于法(fa)拉(la)第电(dian)(dian)(dian)(dian)磁(ci)感应(ying)定律，即在变(bian)(bian)化的(de)磁(ci)场(chang)中会(hui)产(chan)生电(dian)(dian)(dian)(dian)动(dong)势。通过改变(bian)(bian)原(yuan)(yuan)线圈(quan)(quan)和(he)次(ci)级(ji)线圈(quan)(quan)的(de)匝数比例(li)，变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)可以将(jiang)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)(ya)从(cong)高压(ya)(ya)(ya)(ya)降到低(di)压(ya)(ya)(ya)(ya)或从(cong)低(di)压(ya)(ya)(ya)(ya)升(sheng)到高压(ya)(ya)(ya)(ya)。变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)广(guang)泛(fan)应(ying)用(yong)于电(dian)(dian)(dian)(dian)力输(shu)配电(dian)(dian)(dian)(dian)、电(dian)(dian)(dian)(dian)子设(she)备(bei)(bei)、通讯(xun)系统(tong)等领域(yu)。中山直销变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)制造厂家贴(tie)片变(bian)(bian)压(ya)(ya)(ya)(ya)器(qi)(qi)通常由两个(ge)(ge)或多个(ge)(ge)单独的(de)线圈(quan)(quan)组(zu)成，通过电(dian)(dian)(dian)(dian)磁(ci)感应(ying)的(de)原(yuan)(yuan)理来实现电(dian)(dian)(dian)(dian)能的(de)变(bian)(bian)换(huan)。

变压(ya)(ya)器的铁(tie)损(sun)(sun)(sun)包括两个方面(mian)。一(yi)是磁滞损(sun)(sun)(sun)耗(hao)(hao)，当交流(liu)电(dian)流(liu)通过变压(ya)(ya)器时(shi)，通过变压(ya)(ya)器硅钢片(pian)的磁力(li)(li)线其方向(xiang)和(he)大小随之变化，使得硅钢片(pian)内部(bu)分子相互摩擦，放(fang)出热(re)能(neng)，从(cong)而损(sun)(sun)(sun)耗(hao)(hao)了一(yi)部(bu)分电(dian)能(neng)，这便是磁滞损(sun)(sun)(sun)耗(hao)(hao)。另一(yi)是涡(wo)(wo)流(liu)损(sun)(sun)(sun)耗(hao)(hao)，当变压(ya)(ya)器工(gong)作时(shi)。铁(tie)芯(xin)中有磁力(li)(li)线穿过，在与(yu)(yu)磁力(li)(li)线垂直的平面(mian)上就(jiu)会产生(sheng)感应电(dian)流(liu)，由于此电(dian)流(liu)自成(cheng)闭合回路形成(cheng)环流(liu)，且(qie)成(cheng)旋涡(wo)(wo)状，故称为涡(wo)(wo)流(liu)。涡(wo)(wo)流(liu)的存(cun)在使铁(tie)芯(xin)发(fa)热(re)，消耗(hao)(hao)能(neng)量，这种损(sun)(sun)(sun)耗(hao)(hao)称为涡(wo)(wo)流(liu)损(sun)(sun)(sun)耗(hao)(hao)。变压(ya)(ya)器的效率(lv)与(yu)(yu)变压(ya)(ya)器的功率(lv)等级(ji)有密切关系，通常功率(lv)越(yue)(yue)大，损(sun)(sun)(sun)耗(hao)(hao)与(yu)(yu)输出功率(lv)比就(jiu)越(yue)(yue)小，效率(lv)也就(jiu)越(yue)(yue)高。反之，功率(lv)越(yue)(yue)小，效率(lv)也就(jiu)越(yue)(yue)低。
