無功補償原理
首先(xian)你要了解(jie)什么(me)叫無功(gong)(gong)(gong)功(gong)(gong)(gong)率。
無功(gong)(gong)(gong)功(gong)(gong)(gong)率就是不(bu)消(xiao)耗(hao)電(dian)能(neng)(neng)的(de)(de)(de)用電(dian)設(she)備所(suo)消(xiao)耗(hao)的(de)(de)(de)功(gong)(gong)(gong)率，在電(dian)力(li)系統中，無功(gong)(gong)(gong)功(gong)(gong)(gong)率用來(lai)建(jian)立磁(ci)場，作(zuo)為交換能(neng)(neng)量(liang)使(shi)用，他們由電(dian)能(neng)(neng)轉化為磁(ci)場，再由磁(ci)場轉化換為電(dian)能(neng)(neng)，對外部(bu)電(dian)路不(bu)做工(gong)。但是無功(gong)(gong)(gong)功(gong)(gong)(gong)率并不(bu)是無用之功(gong)(gong)(gong)。沒有這(zhe)部(bu)分(fen)功(gong)(gong)(gong)率，就不(bu)能(neng)(neng)建(jian)立感應磁(ci)場，電(dian)動機變壓器(qi)等用電(dian)設(she)備就不(bu)能(neng)(neng)正常工(gong)作(zuo)，對無功(gong)(gong)(gong)補(bu)償(chang)的(de)(de)(de)補(bu)償(chang)原則是既不(bu)能(neng)(neng)少補(bu)，也(ye)不(bu)能(neng)(neng)補(bu)償(chang)過量(liang)。
很(hen)多(duo)電(dian)氣(qi)設(she)備的(de)(de)(de)無功(gong)(gong)(gong)功(gong)(gong)(gong)率比(bi)較(jiao)大，所(suo)以要對它進(jin)行無功(gong)(gong)(gong)補(bu)償(chang)，把這(zhe)樣(yang)的(de)(de)(de)無功功率(lv)補(bu)償進(jin)去(qu)以后，能提高功率因素。改善用(yong)電質量(liang)。
