現代化的(de)(de)(de)(de)(de)(de)工業(ye)企業(ye)廣(guang)泛(fan)的(de)(de)(de)(de)(de)(de)采(cai)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)作為能(neng)源，而發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)廠發(fa)(fa)出的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)往往需(xu)經遠距離傳(chuan)輸(shu)(shu)才(cai)能(neng)到(dao)達(da)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)地區。在(zai)傳(chuan)輸(shu)(shu)的(de)(de)(de)(de)(de)(de)功率恒定時，傳(chuan)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)越高(gao)(gao)(gao)，則(ze)所需(xu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)越小。因(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降正(zheng)比于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。線(xian)(xian)損正(zheng)比于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)(de)(de)平方，所以(yi)用(yong)(yong)(yong)較高(gao)(gao)(gao)的(de)(de)(de)(de)(de)(de)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)可以(yi)獲得較低(di)的(de)(de)(de)(de)(de)(de)線(xian)(xian)路壓(ya)降和線(xian)(xian)路損耗，要制(zhi)造電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)很(hen)高(gao)(gao)(gao)的(de)(de)(de)(de)(de)(de)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機，目前技術很(hen)困(kun)難(nan)，所以(yi)要 用(yong)(yong)(yong)專(zhuan)門的(de)(de)(de)(de)(de)(de)設備將(jiang)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機端(duan)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)升(sheng)高(gao)(gao)(gao)以(yi)后再輸(shu)(shu)送出去，這種專(zhuan)門的(de)(de)(de)(de)(de)(de)設備就是變(bian)壓(ya)器(qi)。另一(yi)方面，在(zai)受電(dian)(dian)(dian)(dian)(dian)(dian)端(duan)又必須(xu)用(yong)(yong)(yong)降壓(ya)變(bian)壓(ya)器(qi)將(jiang)高(gao)(gao)(gao)壓(ya)降低(di)到(dao)配電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，故(gu)要經過一(yi)系(xi)列配電(dian)(dian)(dian)(dian)(dian)(dian)變(bian)壓(ya)器(qi)將(jiang)高(gao)(gao)(gao)壓(ya)降低(di)到(dao)合適(shi)的(de)(de)(de)(de)(de)(de)值以(yi)供使(shi)用(yong)(yong)(yong)。

由以上可(ke)知，變(bian)壓器是一種(zhong)通過改變(bian)電壓而傳輸交流電能的靜止感應電器。 在電力系統中，變(bian)壓器的地位十分重要，不僅所(suo)需數量(liang)多，而且(qie)性(xing)能好，運行安全靠(kao)。

變壓器(qi)除了應用在(zai)電力系統中(zhong)，還(huan)應用在需要特種電(dian)(dian)源(yuan)的(de)(de)工(gong)礦企業中(zhong)。例如：冶煉用的(de)(de)電(dian)(dian)爐(lu)變壓(ya)器，電(dian)(dian)解或化工(gong)用的(de)(de)整流變壓(ya)器，焊接(jie)用的(de)(de)電(dian)(dian)焊變壓(ya)器，試驗用的(de)(de)試驗變壓(ya)器，交通用的(de)(de)牽引變壓(ya)器，以及補償用的(de)(de)電(dian)(dian)抗(kang)器，保護用的(de)(de)消弧線圈，測量用的(de)(de)互(hu)感器等(deng)。
