高速铁路雷击跳闸率的研究

介绍了牵引网电气几何模型,并利用暴露距离分别计算了牵引网系统中各导线遭受雷击的概率,并推导了相关计算公式,对加强线采取避雷器前后牵引网雷击跳闸率进行了计算,由于该模型充分考虑了牵引网实际几何参数,因此其计算结果对高速铁路的防雷保护有一定的参考价值。

Researches on Rate of Lightning Trip-out of Traction Network for High Speed Railway

The paper introduces several geometrical models for traction power supply network,and calculates the thunder striking rates of each conductor in the traction network,gets relative calculation formula,computing the tripping rate of the traction net after mounting the lightning arrestor;since the geometrical parameters of the traction network has been fully considered in the model,so the results of the calculation have certain reference value for lightning protection of high speed railways.
