摘要:

随着新能源技术的不断发展,多频器件和高压线束的大量应用使新能源车辆电磁兼容问题日趋复杂,研究特种车辆新能源充电线缆的复杂电磁环境效应与防护问题具有重要工程价值。文中选择一种新能源充电线缆,利用三维电磁场仿真软件(CST)建立电磁干扰源和充电线缆模型。基于场线耦合原理,仿真分析高空核电磁脉冲照射下的混合动力装甲车内部新能源充电线缆电磁响应。仿真结果表明,同一线束同种线缆横截面积越大,线缆端口耦合电流越大;在同一干扰脉冲照射下,不同线缆端口耦合电流达到峰值的时间以及开始衰减的时间不同;以及线缆布局影响线缆端口耦合电流的大小;线缆阻抗匹配时的耦合电流远远大于阻抗失配时的耦合电流;新能源充电线缆与传统车载SYV-50-3同轴线缆的高空核电磁脉冲响应变化规律吻合良好。

Abstract:

With the development of new energy technology, the application of multi-frequency devices and high-voltage wire harness makes the electromagnetic compatibility of new energy vehicles become more and more complicated. It is of great engineering value to study the complex electromagnetic environment effect and protection of the new energy charging cable of special vehicle. In this paper, a new energy charging cable was selected, and the electromagnetic interference source and the charging cable model were established by using the three-dimensional electromagnetic field simulation software (CST). Based on the field-line coupling principle, the electromagnetic response of recharged cables in hybrid armored vehicles irradiated by high altitude nuclear electromagnetic pulse was simulated and analyzed. The simulation results showed that the larger the cross-sectional area of the same cable, the greater the coupling current of the cable port. Under the same interference pulse, the peak time and the beginning attenuation time of the coupling current at different cable ports were different, and the cable layout affected the coupling current at the cable port. The coupling current of cable impedance matching was much larger than that of load impedance mismatch, and the high altitude nuclear electromagnetic pulse response of new energy charging cable was in good agreement with that of traditional SYV-50-3 coaxial cable.

Key words: new energy vehicle charging cable, high-altitude nuclear electromagnetic pulse, hybrid armored vehicle, electromagnetic response, electromagnetic compatibility, CST
