摘要
分析了影响异步电动机功率因数降低的因素和提高功率因数所采取的措施,从几个方面分别介绍了并联无功补偿电容量的确定方法和提高功率因数后的计算降损效益,最后用实例论述了有无并联电容器对同一负载的耗电量与节约电能的影响。
The paper analyzed the causes resulting in the decrease in the power factor of asynchronous motor and the measures took to increase the power factor,as well introduced the methods of determining the capacitance for shunt reactive power compensation and calculating the efficiency loss after the increase of power factor.Moreover,it respectively described the power consumption of the same load with shunt capacitor and without shunt capacitor.
