电力接地网使用寿命评估模式的研究

摘要

对变电站土壤进行理化性能分析，并使用熵权法进行土壤的腐蚀性评价；筛选现场实际中影响接地网腐蚀的关键因素，并赋予各因素一定的权重值；结合土壤的腐蚀性及现场影响接地网腐蚀的关键因素的权重，对电力接地网使用寿命进行评估。%lt analyzes physical and chemical properties of the substation soil and evaluates the soil corrosivity by entropy method,and Screens the key factors of affecting grounding grid corrosion in the actual site,gives a cer-tain weight value to each factor. Final y,this article evaluates the life of electricity grounding combined with soil corrosivity and the key factors weight of affecting grounding grid corrosion in site.
