電容器安裝容量的確定

1、附錄電容器安裝容量的確定已知負(fù)荷功率為P，補(bǔ)償前的功率因數(shù)為COS1，需提高功率因數(shù)到COS2，所需電容器的容量Q可按下式計(jì)算： 1 1QP（1 1 ）（Kvar） COS21 COS22也可按照COS1及COS2之值由下表直接查出每千乏負(fù)荷所需補(bǔ)償用電容器千乏數(shù)，再以此值乘以負(fù)荷功率即可。如：COS10.66，COS20.96，從表中查得每千乏負(fù)荷所需補(bǔ)償用電容器千乏數(shù)為0.85，若負(fù)荷功率1000千瓦，則所需補(bǔ)償電容器的總?cè)萘繛椋?0.85×1000850千瓦 。補(bǔ)償前為得到所需COS2每千瓦負(fù)荷所需電容器之千乏數(shù)tan1cos10.700.750.800.820.840.860
