摘要:
为了准确分析雷电辐射电磁场对电力设备的影响,该文基于Heidler函数的雷电流近似数值模型,推导了水平理想导体地面上雷电电磁场的近似计算公式。运用时域积分方程方法分析了雷电辐射电磁场下铁塔的电磁散射特性。结果表明,铁塔表面感应电流幅值与雷击点和铁塔的距离有关,与雷击点和铁塔的方位角无关。
Abstract:
In order to analyze the influences of lightning radiation electromagnetic fields on power equipments accurately,the approximate computational formula of lightning radiation electromagnetic fields for horizontal perfect ground is derived based on the approximate numerical expression of lightning current of Heidler function.The transient electromagnetic scattering properties of high voltage iron towers under lightning radiation electromagnetic fields are analyzed by time domain integral equation(TDIE)method.The results indicate that the induced current amplitude on the surfaces of iron towers mainly depends on the distance between the towers and lightning strike positions,has nothing to do with the azimuths between the towers and lightning strike positions.
