DEVELOPMENT OF PULSE CURRENT SENSOR

本文阐述了运用互感器法测量强脉冲电流的正确性，并对应用于避雷器放电电流测量的传感器的结构进行了研究。强脉冲电流频谱丰富，值域较宽，其传感器的研制较困难。本文从传感器材料的选择、模拟计算、频率响应分析到冲击试验结果，从多方面进行了论述，证明了这种传感器具有良好的应用价值。

Since the frequency spectrum of strong pulsecurrent is abundant and the value domain is wide,it isdifficult to dvelop a sensor to measure it. In this paper,themeasurement method of strong pulse current using instrumentaltransformer is described. The structure of a sensor in themeasurement of arrester discharge current is discussed indetail. The time domain simulation and frequency domainresponse are analyzed.The choice of the sensor materials isdiscussed and the impulse tests have been developed. Theon-line operation of the sensor shows that it can be appliedin practice.
