摘　　要：电气化铁路往往会对埋地管道产生杂散电流干扰。本文阐述了交流电气化铁路产生的杂散电流对埋地油气管道腐蚀的基本原理。通过对某成品油埋地钢制管道的管地电位监测发现电气化铁路对其产生较强的杂散电流干扰,安装排流设施保护后,通过对比排流前后的测试数据,杂散电流干扰降低,对管道起到了有效防护。Electrified railways often cause stray current interference to buried pipelines.This article explains the basic principle of the corrosion of buried oil and gas pipelines caused by stray currents generated by electrified railways.Through monitoring the potential of a buried steel pipeline for finished oil products,it was found that electrified railways cause strong stray current interference.After installing drainage facilities for protection,the stray current interference was reduced by comparing the test data before and after drainage,effectively protecting the pipeline.
