摘　　要：Viaduct structure is widely used in China's high-speed railway. It is of great significance to study the electric field distribution of overhead contact system in Lightning Environment for elucidating the lightning strike mechanism of high-speed railway. In this paper, combined with the leader development model and the actual parameters of China's high-speed railway catenary system, a three-dimensional electric field simulation model of overhead bridge catenary system is established, and the leader model is treated equivalently. The distribution of lightning strike rate of overhead contact system of high-speed railway viaduct can be used as an important reference for lightning protection. In order to effectively solve this problem and avoid the risk of lightning stroke, the design of lightning protection system for high-speed railway traction power supply network is briefly analyzed for reference.
