| 摘 要： | 针对格拉段经过青藏高原高土壤电阻率的多年冻土地区,提出了铁路沿线变电站采用立体接地网降低接地电阻,并从地网面积、地网中垂直接地体及季节变化等的影响分析了立体地网在冻土地区的接地降阻效果。分析表明,参数合适的立体地网比水平接地网降阻效果更好。

| Abstract: | To reduce the grounding resistance of substations in p erennial frozen sediment soil of Qinghai-Tibet plateau, The 3D grounding grid i s studied. The influence of area, vertical conductors and season alteration on g rounding resistance is analyzed. Some available parameters of 3Dgrounding grid a re proposed. The results show that 3Dgrounding grid has better effect than horiz ontal grounding grid. The analysis results provide a very useful reference to el ectrical engineers. |
