主接地网材料的选择及应用

Selection and Application of Main Grounding Grid Materials

结合当地土壤地质条件,基于寿阳220 k V及110 k V变电站的大量数据分析,通过对铜接地网、铜覆钢接地网、镀锌扁钢接地网等常用接地材料进行合理性计算和分析。通过计算结果可知,本工程选用-80mm×10 mm镀锌扁钢为主接地网材料,满足腐蚀与热稳定的要求。结合考察在昌吉地区工程中镀锌扁钢均能满足规范要求,工程最终选用镀锌扁钢为主接地网材料。

Combined with the local geological conditions of soil, analysis of a large amount of data of Shouyang 220 kVand 110 kV substation based on the copper grounding grid, copper clad steel galvanized flat steel grounding grid,grounding grounding materials commonly used reasonable calculation and grounding calculation is used in the projectof -80 mmx 10 mm galvanized flat steel grounding grid by calculation. Meet the material, corrosion and thermalstability. Combined with the investigation in the Changji area of engineering application of galvanized flat steel canmeet the standard requirements, the final selection of engineering materials mainly galvanized flat steel grounding gridfor the optimal solution.
