摘要 为防止雷电电磁脉冲或其他强电磁脉冲耦合过电压进入电源线毁坏电子设备,研究分析了电磁脉冲耦合的特点,设计了一种带双重隔离的单相交流电源隔离防护电路,并对实验电路进行仿真;依据仿真结果搭建了功率为2 k W的实验样机,并进行高电压检测。测试结果表明,该样机对雷电电磁脉冲和其它强电磁脉冲耦合过电压具有较好的防护效果,能有效提升雷达等武器装备的全天候作战能力,减小军事和经济损失。 In order to prevent the overvohage of lightning electromagnetic pulse or other strong electromagnetic pulse from coupling into the power line to damage the electronic equipment, this paper studies and analyzes the coupling characteristic of electromagnetic pulse, then designs a single-phase protecting circuit of alternating current with double isolation, and simulates the experimental circuit. According to the simulation results, the paper finally sets up an experimental prototype and high voltage test is performed. Test results show that the prototype has good protective effect for lightning electromagnetic and other strong electromagnetic pulse, thus effectively improving round-the-clock combat missions of radar and other equipment, and reducing the loss of military and economic.
