摘要
变电站接地设计关系到电网安全运行。针对接地设计中接地电阻、接地电流、土壤电阻率及季节系数等参数的取值进行了探讨,列举了设计中常用的降阻措施。分析了接地材料的防腐问题,提出了相应的处理方法。
The design of conductive earth in substation is related to the safe operation of power network.. This article analyzes such parameters as earth resistance, earth electric current, soil resistivity and season factor, then lists some common measure to reduce resistance. It also analyses corrosion problem of earthing material and put forward its measures.
