高压直流接地极对埋地管道的干扰与防护

摘要

Interference mechanism, test methods, research status and main protective measures were summarized,the problems existing in the research were analyzed.In order to solve the problems, suggestions for the improvement of HVDC interference evaluation standard, exploration of HVDC interference mechanism and the development of pipeline protection methods of HVDC interference area were put forward, which is of reference significance to prevent the interference and destruction of direct stray current on buried pipeline.%文中对直流杂散电流对埋地管道的干扰机理、检测方法、研究现状以及主要防护措施等进行了总结,对研究中存在的问题进行了分析,并针对问题提出了完善高压直流干扰评价标准、研究高压直流干扰机理和开发高压直流干扰区管道防护方法等相关防护建议,对防止直流杂散电流对埋地管道的干扰破坏具有参考意义.
