摘要
地网腐蚀一直是导致接地故障的主要原因之一,因而研究在不同土壤环境下接地钢材的腐蚀特性具有现实意义。本文分析接地网在土壤中的腐蚀影响因素;对湖南湘南地区的土壤进行理化性质试验;从不同含量的Cl-,SO42-以及不同pH值等方面分析研究其对于接地钢材的腐蚀规律。该研究结果为后期指导湖南电网湘南区域接地钢材的防腐提供了依据。
Grounding steel corrosion has been one of the main reasons of ground fault.The physical and chemical properties of the soil in south Hunan was tested.The paper analyzes the corrosion factors of grounding grid in the soil,grounding steel corrosion rule from different levels of Cl-,SO2-4 and PH value.The results can provide guide for the prevention measure of grounding steel for power grid in south Hunan.
