地铁杂散电流排流网钢筋截面计算

Analysis of the Stray Current in Rail Transit and the Steel Section in Current Drainage Net

针对城市轨道交通直流供电系统特点建立了杂散电流的计算模型并进行了仿真。根据规程的要求,提出了一种排流网钢筋总截面积的计算方法,并结合深圳地铁1号线的数据进行了分析计算,为系统设计提供了理论依据。

Based on the characteristics of the DC traction power system in rail transit, a numerical model is set up to calculate the leakage current and the potential variation distribution.This paper discusses the parameters of the simulation result,which have effected the leakage current and potential variation distribution,and provides a theorectic basis for the system design.
