Description

功率补偿节能器
本实用新型属于电器节能技术领域，涉及一种将无功功率转变成有功功率的功率补偿装置的改进。
目前，对负载特别是感性负载的功率补偿，虽然功率因数提高了，但电流减小的较小，节电效果不理想。
本实用新型的目的是提供一种在负载上并接电容的功率补偿节能器。
本实用新型的技术方案如下：
在负载上并接有星形连接的电容，每个电容的电容值为：
本实用新型的优点是：可使负载工作电流减少1/3左右，启动电流减少一半，投资小，节电效果好。
图1是本实用新型的电路图；
下面结合附图详细叙述其施实例：
其中：D是负载、C是电容、Q是电容值、IH是电机的额定电流、COS是额定情况下电机的功率因数。当负载D的大小确定后，电容值根据计算公式计算出来，将其电容首先星接后再分别并接在负载上。
