摘要 在现代牵引供电系统中,受电弓和接触网系统为列车提供电能,滑板和接触线之间的接触电阻直接影响了电能的传输质量。本文首先基于弓网接触电阻模型,分析了静态接触电阻的影响因素; 然后,考虑以往研究的不足,采用动力学理论构建了弓网仿真模型,得到弓网间接触力曲线,通过将动态接触力引入接触电阻模型,获得了实际运行中弓网接触电阻的变化趋势。考虑不同车速、电流大小等实际运行工况,分析了动态电阻的各项统计值和变化趋势。

Abstract:In modern traction power system, the pantograph and the catenary are used to provide electric energy for trains. The contact resistance between the pantograph strip and the contact wire affects the transmission quality of electric energy. This paper firstly analyses the influence of some factors on the contact resistance based on the contact resistance model. Then considering the shortfalls of previous studies, the dynamic theory is used to construct the pantograph and catenary simulation model. The contact force curve is obtained. Through introducing the dynamic contact force into the contact resistance model. The change of the contact resistance is obtained. Considering the real working conditions (such as different train speeds, different magnitudes of current), the statistics and change of the dynamic contact resistance are analysed.
