大型铁路站场钢轨电位分析

大型铁路站场人员密集,牵引回流大,钢轨电位升高给道旁人员、设备的安全带来严重威胁。以钢轨视在阻抗为表征参量,对大型铁路站场的线路端部、多股道道岔以及含有集中接地网等典型工况下,钢轨电位的分布进行了分析; 最后将分析结果与普通线路条件下的结果进行对比,根据其钢轨电位的分布特征为站场附近接地系统的设置提供了一些建议。

Analysis of Rail Potential for Large Railway Station

For densely populated large railway station, the huge traction return current and the rise of rail potential pose a serious threat to the safety of people and devices along the road With the apparent impedance of the rail as the characteristic parameter, the rail potential distribution was analyzed under the typical complex working conditions in the large railway station. Then, the results were compared with the data obtained from common conditions. Finally, some advice was proposed according to the rail potential distribution characteristics.
