摘要
高压储能电容器在出厂试验中需要有效的检验手段, 在使用和存贮中绝缘状况老化的判断也需要有效的检测方法, 直流局部放电检测是解决上述问题的有效手段。通过检测高压电容器的直流局部放电信号, 分析其信号参量可以对其状况进行有效的评估。该检测基于Matlab软件, 通过调用ActiveDSO, 用PC机控制示波器, 在MATLAB环境中获取示波器采集的数据并进行数据分析。试验结果表明不同状况的高压电容器的局部放电信号参量具有明显不同。
At production examination of high-voltage capacitor becoming finished product, it needs an available method to verify it. During running and storage, estimation of insulated status needs an available method, too. However, the partial discharge inspection at direct current voltage is a good method for resolving above problem. The status of high-voltage capacitor is distinguished by testing the partial discharge and by analyzing the signal parameters at direct current voltage. The test bases on Matlab software, and we use Personal Computer to control oscilloscope through invoking ActiveDSO, we gain datum gathered by oscilloscope, and we analyse them under Matlab environment. Finally, the results indicate that there are different signal parameters between different status high-voltage capacitors.
