摘　　要：考虑雷电天气对接触网的影响,采用非齐次泊松过程对雷电发生进行建模,基于接触网电气几何模型分析雷击的位置和范围,利用蒙特卡罗模拟方法研究雷电影响下的接触网跳闸率,对提高接触网的防雷性能和可靠性具有重要意义。Considering the influence of lightning weather on OCS,the non-homogeneous Poisson process is used to model the lightning process.The location and range of lightning strike are analyzed based on the OCS electrical geometric model and the trip-out rate of OCS under the influence of lightning is calculated by using Monte Carlo simulation method,which is of great significance to improve the lightning protection performance and reliability of OCS.
