资料介绍

通过分析电力电容器放电瞬间的动态过程,指出了传统电容器模型的局限性,并完善了电力电容器等效电路模型。提出了一种测量电力电容器参数的新方法——脉冲电流法,推导出电力电容器突加直流负载时端电压的暂态表达式,计算出电力电容器的内感,并设计了电力电容器等效串联内阻测量装置。通过理论分析和大量试验,验证了测量装置测试的正确性。

By analyzing power capacitor discharge instantly process, the limitation of traditional capacitor model was pointed out. And the equivalent model of power capacitor was improved. The paper also proposed a new method for measuring capacitor internal resistance, derived the transient expression of capacitor voltage by suddenly applied DC load, calculated capacitor internal inductance, and designed the device for measuring capacitor internal resistance. The theoretical analysis and a large number of experiments verified the correctness of the method.
