To Adopt Three-Dimension Method for Designing Earth Resistance of Substation

采用三维方法(ATN方案)设计变电站的接地电阻,可使接地电阻比传统设计更加准确,并使变电站的接地电阻满足R≤0.5Ω的国家标准规定。并结合现有国内外接地的新材料、新技术、新工艺,通过举例分析计算,证明三维方法可使变电站接地网接地电阻达到最佳效果。

Three-dimensional method （A-T-N scheme） for designing earthing resistance of substation can be more accurately than traditional design, which makes the earthing resistance of substation to satisfy the national standard stipulation of R≤ 0.5 Ω. Combined with existing domestic and international new material and new technology＇, and through the analysis and calculation of giving an example, it is proved that three-dimension method can make the best effect for earthing resistance of substation earthing net.
