摘要(Abstract):

为更好地研究接地网的腐蚀行为,以某变电站为例,对土壤的含水量、含盐量、氯离子、硫酸根离子等进行检测,用电化学检测手段分析了土壤的腐蚀电流和极化曲线,采用数学模型计算年平均腐蚀损失,从而估算其运行寿命,为接地网的运行和维护提供理论依据。
In order to achieve better research on the corrosion behavior of ground grid,this paper tests water content,salt content,chloride ion,sulfate ion etc,analyzes the corrosion current and polarization curve using electro-chemical test method and calculates the annual mean corrosion lost with the mathematical model so as to estimate the operation lifetime and offer theoretical basis for the operation and maintenance of ground grid.
