摘　　要：邻近雷击电磁场产生的间接效应会对电子电气设备的安全运行产生巨大威胁。实验室条件下,通常将Marx发生器产生的脉冲高压注入场照射器,模拟邻近雷击脉冲电场环境。针对雷电高压脉冲注入方式对场照射器电场分布的影响问题,开展仿真分析和实验测试。建立邻近雷击脉冲电场模拟装置模型,获取了场照射器空间中电磁场的分布情况,并与实测结果进行对比,验证了仿真的有效性。基于所建模型,设置4种不同的引线注入方式,对比场照射器空间中电磁场及其导线的耦合电流情况,结合仿真结果给出了高压脉冲注入方式优化方案。研究结果为邻近雷击脉冲电场效应的准确可靠评估提供了可行方法,对电子电气设备的邻近雷击防护设计具有重要意义。The indirect effect caused by the electromagnetic environment of nearby lightning strikes poses a serious threat to the security of electronic and electrical equipment.In laboratories,the common method to produce the required close-in electric field is to inject the high-voltage pulse of the Marx generator into a field irradiator.With regard to the issue of the impact of high-voltage lightning pulse injection patterns on the electric field distribution of a field irradiator,the simulation analysis and experimental testing were carried out.A model of a nearby lightning strike pulse electric field simulation device was established to obtain the distribution of the electromagnetic field in the space around the field irradiator.The obtained simulation results were then compared with actual measurement results to verify the effectiveness of the simulation.After that,the four different injection modes were set up based on the built model.The electric field distribution of the field irradiator and the current coupled in the wire were compared,and then the optimized injection method was developed.The results provide an applicable method for the accurate evaluation of lightning indirect effect,and it is of great significance to the design of nearby lightning protection for electronic and electrical equipment.
