無功補償原理
首先你要了解什(shen)么叫(jiao)無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率。
無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率就是(shi)不(bu)(bu)消耗電(dian)(dian)(dian)能的(de)(de)用(yong)電(dian)(dian)(dian)設(she)備(bei)所消耗的(de)(de)功(gong)(gong)(gong)率，在電(dian)(dian)(dian)力系(xi)統中，無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率用(yong)來(lai)建立磁(ci)(ci)(ci)場(chang)，作為(wei)(wei)交(jiao)換能量使用(yong)，他們由電(dian)(dian)(dian)能轉化為(wei)(wei)磁(ci)(ci)(ci)場(chang)，再(zai)由磁(ci)(ci)(ci)場(chang)轉化換為(wei)(wei)電(dian)(dian)(dian)能，對(dui)外部電(dian)(dian)(dian)路(lu)不(bu)(bu)做工。但是(shi)無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率并(bing)不(bu)(bu)是(shi)無(wu)(wu)用(yong)之功(gong)(gong)(gong)。沒有這部分功(gong)(gong)(gong)率，就不(bu)(bu)能建立感應磁(ci)(ci)(ci)場(chang)，電(dian)(dian)(dian)動機變壓器等用(yong)電(dian)(dian)(dian)設(she)備(bei)就不(bu)(bu)能正常工作，對(dui)無(wu)(wu)功(gong)(gong)(gong)補(bu)償的(de)(de)補(bu)償原則是(shi)既不(bu)(bu)能少補(bu)，也不(bu)(bu)能補(bu)償過量。
很多(duo)電(dian)(dian)(dian)氣設(she)備(bei)的(de)(de)無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率比較大(da)，所以要對(dui)它進行無(wu)(wu)功(gong)(gong)(gong)補(bu)償，把這樣的(de)(de)無(wu)功功率補償進(jin)去以后，能(neng)提(ti)高功率因素(su)。改善用電質量。
