摘要
分析了25 kV铁道输电线路及电力机车的雷击点,计算了避雷器对被保护设备的有效距离,并用PSCAD对其进行仿真,计算及仿真结果表明,选择合适的避雷器可以很好地保护车顶高压电气设备。该研究为电力机车高压电气设备的有效防雷过电压提供了参考。
The lightning strike the position of transmission line and electric locomotive is studied, effective distance of the arrester to protected equipment is calculated, and is simulated by PSCAD, the calculation and simulation results show that, the appropriate arrester can well protect the high voltage electrical equipment on the locomotive roof. The reference for effective lightning protection overvoltage of the high voltage electrical equipment on electric locomotive is provided.
