變(bian)(bian)壓(ya)器是利(li)用電(dian)(dian)(dian)(dian)磁(ci)(ci)感應(ying)的(de)(de)原(yuan)理來改變(bian)(bian)交(jiao)流電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)裝置，主要構件是初級線(xian)圈、次級線(xian)圈和鐵心 （磁(ci)(ci)芯）。在(zai)電(dian)(dian)(dian)(dian)器設備和無線(xian)電(dian)(dian)(dian)(dian)路(lu)中，常(chang)用作(zuo)升降(jiang)電(dian)(dian)(dian)(dian)壓(ya)、匹配阻抗、安(an)全(quan)隔離等。在(zai)發(fa)電(dian)(dian)(dian)(dian)機中，不(bu)管是線(xian)圈運動(dong)通(tong)(tong)過磁(ci)(ci)場或(huo)磁(ci)(ci)場運動(dong)通(tong)(tong)過固定(ding)線(xian)圈，均能在(zai)線(xian)圈中感應(ying)電(dian)(dian)(dian)(dian)勢。此兩種情況(kuang)，磁(ci)(ci)通(tong)(tong)的(de)(de)值(zhi)均不(bu)變(bian)(bian)，但與線(xian)圈相交(jiao)鏈(lian)的(de)(de)磁(ci)(ci)通(tong)(tong)數量卻(que)有變(bian)(bian)動(dong)，這是互(hu)感應(ying)的(de)(de)原(yuan)理。變(bian)(bian)壓(ya)器就是一種利(li)用電(dian)(dian)(dian)(dian)磁(ci)(ci)互(hu)感應(ying)變(bian)(bian)換(huan)電(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)流和阻抗的(de)(de)器件。
