| 摘 要： | 该文探讨外积分式Rogowski线圈测量瞬态单脉冲强电流时积分电路的时间常数对输出电压的影响，指出引起积分电路输出电压波形畸变的原因，提出电压波形畸变的校正方法。电压波形畸变的校正方法适用于外积分式Rogowski线圈积分电路的时间常数低于10倍脉冲强电流脉宽的情况。采用波形校正方法可以大幅减少脉冲强电流的测量误差，扩大了Rogowski线圈在脉冲强流测量中的应用范围。

| Abstract: | An effect of integration circuit time constant on output voltage is conducted. W hen using external integration Rogowski coils to measure transient single pulse current.The cause o f voltage waveform distortion of integration circuit is given and the revision m ethod of this kind of distortion is offered. The revision method is fit for the measurement in which the integration circuit time constant of external integr ation Rogowski coil is not 10 times greater than the width of pulse current. Th is kind of correction greatly reduces the error in the measurement of pulse cur rent and enlarges the application range of Rogowski coil. |
