摘要
通过分析土壤电阻率和接地极极环自身参数对电位分布的影响,为工程实际提供理论依据。研究运用接地分析软件CDEGS来模拟分析地表电位分布的影响因素,以实际工程土壤简化模型,逐个分析相关参数具体对地表电位分布的影响,比较了不同形式接地极在不同埋深下地表电位和跨步电压的分布,得出双圆环接地极实用价值更大。基于分析结果,可为后续新建直流接地极设计选址及直流线路设计规划提供参考依据。
This research analyzes the influence of soil resistivity and ground pole’s own parameters on the potential distribution,and provides theoretical basis for engineering practice.In this paper,professional grounding analysis software CDEGS was used to simulate and analyze the influencing factors of surface potential distribution.With the actual engineering soil simplified model,the influence of related parameters on the surface potential distribution was analyzed one by one.The distribution of surface potentials and step voltage at different buried depths and types of grounding electrodes is compared,it is concluded that the double-ring grounding pole is more practical.Based on the analysis results,it can provide reference for the design and location of the new DC grounding electrode and the design and planning of the DC line.
