摘要
为了指导以后的工作,总结了地网改造经验,介绍了非均匀土壤地区110kV坦岭变的接地网改造概况。针对接地电阻超标的不同变电站,只有从个案的地质、地形等方面综合选择合适方案才能有效解决问题。
In order to guide future work,the article summarizes the experience in the grounding grids retrofit,introduces the heterogeneous soil area 110kV Tan Ling of grounding grids retrofit。In the light of grounding resistance exceed the standard of different substations,only from the geological topography and other aspects of case, comprehensive selection scheme can effectively solve the problem.
