| 摘 要： | 鉴于杂散电流分布的复杂性,建立了轨道-排流网-大地-埋地管道连续模型。利用微分方程推导出双边供电方式下杂散电流的解析公式,并用Matlab软件仿真验证模型的正确性。比较了轨地绝缘存在和不存在破损时的杂散电流变化情况,提出了相应的防护措施。

| Abstract: | Due to the complexity of stray current distribution,a continuous model of rail-drainage net-earth-buried pipeline is established.Then,an analytical formula of stray current under bilateral power supply mode is derived by using differential equations,and then tested through MATLAB soft ware simulation.The changes of stray current when the rail/earth insulation damages and when the current drainage net works in normal situation are compared,corresponding pro tective measures are put forward. |
