瞬态冲击电流测量传感系统的研究

The Study of Sensor for Measuring the Great Instantaneous Current

本文根据瞬态冲击电流的特点 ,探讨了符合国际电工委员会标准要求的测量系统 ,并以对雷电浪涌发生器短路电流波形为例 ,提出了用罗柯夫斯基线圈作为测量传感器的测量系统设计方案 ,该测量系统可用于静电放电电流、雷电电流等瞬态电流的测量。

Based on characteristic of the great instantaneous current, the system of measuring the great instantaneous current is put forward. To validate this system, we test lightning surge generator short circuit current using this measure shunt. This shunt may using in the measurement of lightning pulsed current and the waveform calibration of the lightning surge generator. We also can look this system as a sensor of testing current.
