摘要
简要介绍了杂散电流的产生机理。建立了轨道-排流网-大地-埋地管道连续模型,并对管道电阻和大地电阻进行计算。仿真分析了牵引电流、管道与隧道的距离、土壤电阻率等参数对杂散电流分布的影响,以及存在破损点时管道中杂散电流的变化情况,并提出了适当的防护措施。
The stray current generation mechanism is brieflyintroduced,a continuous rail-drainage net-earth-buried pipelinemodel is established.By calculating the value of pipeline andthe earth resistance,parameters of the traction current,distancebetween pipeline and tunnel soil resistivity and so on that influencethe stray current distribution,as well as the changes ofstray current in the pipeline with breakage points are analyzed.Corresponding protective measures are put forward on the basisof simulation analysis.
