摘要
提出了一种利用电磁暂态程序(EMTP)来计算雷击发生时建筑物内部金属框架上雷电电流分布的方法。该方法的有效性通过实验得到了验证。最后计算了一个尺寸为10 m×10 m×10 m的金属框架内部的雷电磁场分布。结果显示,该方法可用于优化建筑物内部灵敏电子设备的摆放位置,降低雷电电磁脉冲的危害。
A method of calculating the lightning current distribution on the metal frame of building by using electromagnetic transient program （EMTP） was presented. The effect of this method was proved by a laboratory experiment. The lightning-induced magnetic field evaluations for 10 m×10 m×10 m metal frame was calculated. The results showed that this method could be used to optimize the location of sensitive electronic equipment inside the building, it could reduce the harm of lightning electromagnetic pulse.
