无功(gong)(gong)(gong)补偿的工作原理： 在交(jiao)流电(dian)(dian)(dian)路中，由电(dian)(dian)(dian)源(yuan)供给负载的电(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)(lv)(lv)有两种；一(yi)种是(shi)(shi)有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)，一(yi)种是(shi)(shi)无功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)。 有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)是(shi)(shi)保(bao)持用(yong)电(dian)(dian)(dian)设备(bei)正(zheng)常运(yun)行所需(xu)的电(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)(lv)(lv)，也就是(shi)(shi)将电(dian)(dian)(dian)能转换(huan)为其(qi)他形(xing)式能量（机械能、光(guang)能、热能）的电(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)(lv)(lv)。无功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)比(bi)较抽象，它(ta)用(yong)于电(dian)(dian)(dian)路内(nei)电(dian)(dian)(dian)场(chang)与磁场(chang)的交(jiao)换(huan)，并用(yong)来在电(dian)(dian)(dian)气(qi)设备(bei)中建立和(he)(he)维持磁场(chang)的电(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)(lv)(lv)。它(ta)不对外作功(gong)(gong)(gong)，而(er)是(shi)(shi)转变为其(qi)他形(xing)式的能量。凡是(shi)(shi)有电(dian)(dian)(dian)磁线圈的电(dian)(dian)(dian)气(qi)设备(bei)，要建立磁场(chang)，就要消耗(hao)无功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)。 无功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)决不是(shi)(shi)无用(yong)功(gong)(gong)(gong)率(lv)(lv)(lv)，它(ta)的用(yong)处很大。电(dian)(dian)(dian)动(dong)(dong)机需(xu)要建立和(he)(he)维持旋(xuan)转磁场(chang)，使转子(zi)转动(dong)(dong)，从而(er)带动(dong)(dong)机械运(yun)动(dong)(dong)，电(dian)(dian)(dian)动(dong)(dong)机
