击穿电压检测结果准确性的研究

Research on Accuracy of Breakdown Voltage Test Results

分析采样周期、升压速度、过流断闸时间等因素在绝缘材料击穿电压试验过程中对击穿电压值的影响,采用合理的改进工艺或方法,消除或降低试验误差。结果表明:采用数字滤波、加权平均等方法有效降低了击穿电压测量结果的分散性,提高了动态测量的准确度。

The influence of sampling period,voltage rising speed,and overcurrent breaking time on the breakdown voltage of insulating materials in the process of breakdown voltage test was analyzed.Proper improving technology and method was select to eliminate or reduce the error.The results show that the dispersion of test results is reduced by digital filtering,weighted average,and other methods,and the accuracy of dynamic measurement is improved at the same time.
