直流接地极电流对输电线路接地构件的腐蚀影响研究

Corrosive Effect of DC Ground Cround Current Gmunding Electrodes

研究直流接地极电流对输电线路接地构件的腐蚀影响，并对三峡一华东直流线路的接地极电流对周边电力线路的塔基、拉线锚桩可能造成的腐蚀进行分析计算，提出减小地电流影响的防护措施。

This paper presents a study on corrosive effects of DC ground current on grounding electrodes nearby transmissiolline. An analytical calculation was made for the corrosive effects of grounding current of HVDC lines affecting tower founda'nons, gUy wire anchors, etc. A protective measure is proposed for mitigating the corrosive effects of DC ground current.
