摘要
城市轨道交通一般采用直流牵引供电系统,走行轨上最大牵引电流及其持续时间会随着供电区间内牵引列车数的不同而异。本文运用数理统计的方法分析了城市轨道交通走行轨上各种牵引电流出现的概率及其持续的时间,并结合工程实例对走行轨上最大牵引电流的选择提出了建议。
The urban mass transit usually adopts DC traction power supply system. The max traction current and its durative time alter with the number of trains in running rail. This paper analyzes the probability of all kinds of traction current appear through the running rail and its durative time with statistic method. As a result, puts forward some suggestions about how to selection the max traction current with some experiences of the real projects.
