摘　　要：高压直流输电系统接地极单极大地回路运行时,大量电流入地导致接地极附近地电位升高,接地极附近管道及附属设施可能面临管体腐蚀、管体氢脆、防腐蚀层剥离、设备烧蚀等风险。为监检测高压直流接地极对管道的影响,对国内外相关研究案例进行了调研总结,介绍了多种高压直流干扰监检测方法,对其未来的发展方向进行展望并提出了相关建议。When the ground pole monopole geodetic loop of high voltage direct current(HVDC) transmission system is operating,a large amount of current enters the ground,causing the ground potential near the ground pole to rise.The pipelines and auxiliary facilities near the ground pole may face risks such as pipe body corrosion,pipe body hydrogen embrittlement,corrosion layer peeling,and equipment ablation.In order to monitor and test the influence of HVDC ground pole on pipelines,relevant research cases at home and abroad were investigated and summarized.Several HVDC interference monitoring and detection methods are introduced,and their future development direction is prospected and some suggestion are proposed.
