摘要
从设计方案、总造价、年发生费用等经济角度对钢接地网和铜接地网进行了对比分析,结论表明,铜接地网可满足50年运行期,年费用低于钢接地网,进而提出了采用铜接地网的建议,以提高电网的安全稳定运行。
This paper carries on the comparison in the economical angles from aspects of the design proposal,the whole project cost,the cost per year and so on,the results indicates that copper grounding grid can satisfy 50 years operation time,and the cost per year is lower,so can enhance the reliability and the safety of the power grid.
