| 摘 要： | 针对电爆装置在电磁辐射干扰下的射频敏感频率,提出采用场线耦合理论进行分析.建立了电爆装置的传输线模型,推导得到电爆装置吸收功率与入射频率之间的数学表达式,通过数值仿真的方法研究了敏感频率的影响因素.仿真结果表明,电爆装置的脚线长度决定敏感频率;脚线等长而连接方式不同的电爆装置射频敏感频率相同.研究结果可以为电爆装置的射频危害分析提供理论参考.

| Abstract: | The sensitive frequency of electro-explosive devices in EMI is analyzed based on field coupling to line theory. Firstly,the transmission line model of electro-explosive device is built up. Then,the formula of absorption power and incident frequency is given. The influence factors of sensitive frequency are drawn by means of numerical simulation. The simulation results showed that the sensitive frequency of electro-explosive device is decided by the length of its pin. Whether electro-explosive device with th... |
