無功補償原理
首先你要(yao)了解什么(me)叫無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率。
無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率就是(shi)不(bu)消耗電(dian)能(neng)的(de)(de)(de)用(yong)(yong)電(dian)設備所(suo)消耗的(de)(de)(de)功(gong)(gong)(gong)(gong)率，在電(dian)力(li)系統中，無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率用(yong)(yong)來建立(li)磁場(chang)，作為交(jiao)換能(neng)量(liang)(liang)使(shi)用(yong)(yong)，他們由(you)電(dian)能(neng)轉化為磁場(chang)，再由(you)磁場(chang)轉化換為電(dian)能(neng)，對(dui)外部電(dian)路(lu)不(bu)做工。但是(shi)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率并不(bu)是(shi)無用(yong)(yong)之功(gong)(gong)(gong)(gong)。沒有(you)這(zhe)部分(fen)功(gong)(gong)(gong)(gong)率，就不(bu)能(neng)建立(li)感應磁場(chang)，電(dian)動機變壓器等用(yong)(yong)電(dian)設備就不(bu)能(neng)正常工作，對(dui)無功(gong)(gong)(gong)(gong)補償(chang)的(de)(de)(de)補償(chang)原則是(shi)既不(bu)能(neng)少(shao)補，也不(bu)能(neng)補償(chang)過量(liang)(liang)。
很多(duo)電(dian)氣設備的(de)(de)(de)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率比較大，所(suo)以要(yao)對(dui)它進行無功(gong)(gong)(gong)(gong)補償(chang)，把這(zhe)樣的(de)(de)(de)無功功率補償進(jin)去以后(hou)，能(neng)提高功(gong)率因素。改善(shan)用電質量(liang)。
