Research on the Measurement and Evaluation Method of EED' Electromagnetism Impulse Harm

分析了电磁脉冲对电火工品的危害,并采用一种新型白光干涉型光纤传感器对国内某电火工品进行了性能检测与评估试验。试验通过测量电火工品桥丝在电磁环境下温度的变化,利用传感器测得的桥丝温度与调理器输出的感应电压的关系,测量出桥丝上的感应电压,进而对电火工品进行静电放电的效应评估。

This paper analyzes the harm of EED caused by the electromagnetism impulse, and proposes a new type whitelight interferometric optic fiber temperature sensor made a harm evaluating experiment of some electrical initiator. According to measuring the change of temperature of EED under electromagnetic environment and using the relation of EED＇temperature （measured by the sensor） and the inducible voltage （output by conditioner）, the experimentation measures the EED＇inducible voltage and then evaluates the EED under the static discharge.
