变(bian)(bian)(bian)压(ya)(ya)器是(shi)变(bian)(bian)(bian)换(huan)交(jiao)流(liu)(liu)(liu)电(dian)(dian)压(ya)(ya)、电(dian)(dian)流(liu)(liu)(liu)和阻(zu)抗(kang)的(de)(de)器件(jian)，当初级线(xian)(xian)(xian)(xian)(xian)圈(quan)中(zhong)通(tong)(tong)有交(jiao)流(liu)(liu)(liu)电(dian)(dian)流(liu)(liu)(liu)时，铁(tie)芯（或(huo)磁(ci)芯）中(zhong)便产生(sheng)交(jiao)流(liu)(liu)(liu)磁(ci)通(tong)(tong)，使次级线(xian)(xian)(xian)(xian)(xian)圈(quan)中(zhong)感(gan)(gan)应(ying)出电(dian)(dian)压(ya)(ya)（或(huo)电(dian)(dian)流(liu)(liu)(liu)）。变(bian)(bian)(bian)压(ya)(ya)器由铁(tie)芯（或(huo)磁(ci)芯）和线(xian)(xian)(xian)(xian)(xian)圈(quan)组成，线(xian)(xian)(xian)(xian)(xian)圈(quan)有两(liang)(liang)个或(huo)两(liang)(liang)个以(yi)上的(de)(de)绕(rao)组，其(qi)中(zhong)接(jie)电(dian)(dian)源的(de)(de)绕(rao)组叫初级线(xian)(xian)(xian)(xian)(xian)圈(quan)，其(qi)余的(de)(de)绕(rao)组叫次级线(xian)(xian)(xian)(xian)(xian)圈(quan)。在(zai)发(fa)电(dian)(dian)机中(zhong)，不管(guan)是(shi)线(xian)(xian)(xian)(xian)(xian)圈(quan)运动(dong)(dong)通(tong)(tong)过磁(ci)场或(huo)磁(ci)场运动(dong)(dong)通(tong)(tong)过固定(ding)线(xian)(xian)(xian)(xian)(xian)圈(quan)，均能在(zai)线(xian)(xian)(xian)(xian)(xian)圈(quan)中(zhong)感(gan)(gan)应(ying)电(dian)(dian)势，此两(liang)(liang)种情况，磁(ci)通(tong)(tong)的(de)(de)值均不变(bian)(bian)(bian)，但与线(xian)(xian)(xian)(xian)(xian)圈(quan)相交(jiao)链(lian)的(de)(de)磁(ci)通(tong)(tong)数量却有变(bian)(bian)(bian)动(dong)(dong)，这(zhei)是(shi)互感(gan)(gan)应(ying)的(de)(de)原理(li)。变(bian)(bian)(bian)压(ya)(ya)器就(jiu)是(shi)一种利用电(dian)(dian)磁(ci)互感(gan)(gan)应(ying)，变(bian)(bian)(bian)换(huan)电(dian)(dian)压(ya)(ya)，电(dian)(dian)流(liu)(liu)(liu)和阻(zu)抗(kang)的(de)(de)器件(jian)。
