摘要
随着国内城镇加快低碳发展,交流电缆线路与埋地输气管道的建设逐渐形成网络,不可避免地存在并行和交叉的情况。运行中的交流电缆线路所产生杂散电流给埋地金属管线的安全带来威胁。文章概述了交流电缆线路对埋地输气管道的干扰评价指标,并通过模拟仿真技术对输气管线受到的电磁影响进行预测评价,并提出防护方案设计。
As low-carbon development accelerates in urban and rural areas,the construction of AC cable lines and underground gas pipelines has formed a complicated network,leading to a situation in which these underground systems operate parallel to or intersect.The stray current produced by operating AC cable lines poses a serious threat to the safety of buried metal pipe.This paper outlines the evaluating indicator for evaluating the interference of AC cable lines with underground gas pipelines,predicts and assesses the electromagnetic impact on gas pipelines using simulation technology,and put forward the protection scheme design.
