| 摘 要： | 分析单边供电与双边供电下的杂散电流静态分布模型。根据列车的速度、位置、取流大小等随时间发生变化的情况,以轨道-排流网-埋地金属-大地结构的杂散电流静态模型和牵引计算为基础,设计双边供电方式下基于时间-位置-取流变化的杂散电流动态分布模型,并对模型进行计算求解,实现三维仿真。分析杂散电流和轨电位在不同工况下的动态分布规律,得出特定位置杂散电流和轨电位随时间的动态分布。

| Abstract: | The static distribution model of stray current under the circumstance of single side feeding and single locomotive is analyzed.According to the changes in locomotive's speed,position and streams over time,by using the static model of "track-drainage net-buried metal-earth structure" and traction calculation,the dynamic stray current distribution model is designed and calculated based on "time-positionflow" changes,in order to realize a 3D dynamic simulation.By analyzing the dynamic distribution of stray current and rail potential under different conditions,the dynamic stray current and rail potential distribution on specific spot with time is obtained. |
