Research on Stray Current Interference of Urban Subways to Underground Pipelines

摘要:

随着城市的快速发展，地铁作为重要的公共交通方式，其建设规模不断扩大。与此同时，地下管线作为城市基础设施的关键组成部分，承担着能源输送、信息传输等重要功能。然而，地铁运行过程中产生的杂散电流会对地下管线造成干扰，威胁管线的安全运行。旨在解决城市地铁对地下管线的杂散电流干扰问题。通过采集和分析管中电流数据，利用管中电流的相关性和衰减率来判断杂散电流的流入流出位置。基于此，制定了针对性的杂散电流治理方案，包括确定排流位置和选择适合的排流方法。研究结果表明，该方法能够有效定位杂散电流位置，治理方案切实可行，为城市地铁与地下管线的共存环境下的杂散电流干扰问题提供了有效的解决思路。

Abstract:

With the rapid development of cities, the construction scale of subways, an important public transportation mode, is continuously expanding. At the same time, the underground pipelines, as a key part of urban infrastructure, undertake the important functions such as energy conveyance and information transmission. However, the stray current generated during the operation of the subway will cause interference to underground pipelines and threaten the safe operation of the pipelines. The aim is to solve the stray current interference of urban subways to underground pipelines. By collecting and analyzing the current data in the pipeline, the correlation and attenuation rate of the current in the pipeline are used to determine the inflow and outflow locations of the stray current. Based on this, a targeted stray current treatment scheme is formulated, including determining the electric drainage location and selecting a suitable electric drainage method. The research results show that this method can effectively locate the location of the stray current, and the treatment scheme is feasible, providing an effective solution to the problem of stray current interference in the co-existence environment of urban subways and underground pipelines.
