变电站接地网防锈蚀

Rust and Corrosion Prevention for Grounding Network in Substation

总结了接地网电化学方法防锈蚀应用试验结果.介绍外加电流阴极保护能有效地减缓接地网的腐蚀,保护度达62%～91.6%.开发的NAS地网材料具有很好的耐蚀性,与使用条件相同的碳钢相比,腐蚀速率低了一个数量级.

This paper summarizes the application test results of electro-chemical rust and erosion prevention for grounding network and it also introduces the way using additional current cathode to slow the rust of grounding network efficiently,with a success of 62%～91.6%.The developed NAS grounding materials have very good resistence against erosion to make the rust speed quantitatively lower that when using carbon steel under the same condition.
