摘要
为避免杂散电流的流入形成杂散电流干扰腐蚀,以平行于城市地铁线路的埋地天然气管道为例,分别对地下地铁线路与地上地铁高架线路对埋地输气管道杂散电流干扰的影响进行分析。针对直流杂散电流与交流杂散电流对埋地输气管道的干扰规律进行监测与分析,并针对不同的杂散电流干扰情况提出合理的排流防护措施,为埋地输气管道的安全运行提供技术保障。
In order to avoid interference corrosion caused by stray current inflow,the influence of underground subway line and overhead subway line on stray current interference of buried gas transmission pipeline is analyzed by taking buried natural gas pipeline parallel to urban subway line as an example.The interference law of DC stray current and AC stray current on buried gas pipeline is monitored and analyzed.According to different stray current interference conditions,reasonable drainage protection measures are proposed to provide technical guarantee for the safe operation of buried gas pipeline.
