摘要
本文对高边坡狭窄河床地形特性的水电站接地网改造方案进行了阐述,针对高边坡狭窄河床的地貌特性,分析了水下接地网敷设方格网格的安全性能,并对水下接地体长度进行准确计算。科学有效的水下接地网敷设施工方法使经济成本与安全性能达到最优。
In this paper,the reconstruction scheme of the grounding grid of hydropower station with high slope and narrow riverbed topography is expounded.According to the geomorphic characteristics of high slope and narrow riverbed,the safety performance of square grid laying of underwater grounding grid is analyzed.The length of the underwater grounding body is calculated accurately.The scientific and effective construction method of laying the underwater grounding grid can optimize the economic cost and safety performance.
