无(wu)功(gong)(gong)(gong)(gong)补偿的(de)(de)工作原理：   在(zai)交流电(dian)路(lu)中(zhong)，由电(dian)源供给负载(zai)的(de)(de)电(dian)功(gong)(gong)(gong)(gong)率(lv)有两种；一种是有功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)，一种是无(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)。   有功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)是保持(chi)用(yong)(yong)电(dian)设备(bei)正常运(yun)行所需的(de)(de)电(dian)功(gong)(gong)(gong)(gong)率(lv)，也就是将(jiang)电(dian)能(neng)转(zhuan)换(huan)为其(qi)他形式(shi)能(neng)量（机(ji)械能(neng)、光能(neng)、热能(neng)）的(de)(de)电(dian)功(gong)(gong)(gong)(gong)率(lv)。无(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)比(bi)较(jiao)抽象，它(ta)用(yong)(yong)于(yu)电(dian)路(lu)内电(dian)场(chang)(chang)(chang)与磁(ci)场(chang)(chang)(chang)的(de)(de)交换(huan)，并用(yong)(yong)来在(zai)电(dian)气设备(bei)中(zhong)建(jian)立(li)(li)和(he)维(wei)持(chi)磁(ci)场(chang)(chang)(chang)的(de)(de)电(dian)功(gong)(gong)(gong)(gong)率(lv)。它(ta)不对外作功(gong)(gong)(gong)(gong)，而是转(zhuan)变(bian)为其(qi)他形式(shi)的(de)(de)能(neng)量。凡是有电(dian)磁(ci)线圈的(de)(de)电(dian)气设备(bei)，要(yao)建(jian)立(li)(li)磁(ci)场(chang)(chang)(chang)，就要(yao)消耗无(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)。   无(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率(lv)决不是无(wu)用(yong)(yong)功(gong)(gong)(gong)(gong)率(lv)，它(ta)的(de)(de)用(yong)(yong)处很(hen)大。电(dian)动(dong)机(ji)需要(yao)建(jian)立(li)(li)和(he)维(wei)持(chi)旋转(zhuan)磁(ci)场(chang)(chang)(chang)，使转(zhuan)子转(zhuan)动(dong)，从而带(dai)动(dong)机(ji)械运(yun)动(dong)，电(dian)动(dong)机(ji)
