摘要
针对传统接地引下线存在的易腐蚀和材料质地太硬的缺陷,提出将接地引下线的制作材料用镀锌钢绞线代替,同时制定了钢绞线接地引下线的安装方法,并通过热稳定计算确定了钢绞线截面积。实例应用结果表明,该优化设计方法安装简单、方便,成本小,同时在减少输电线路维护工作量、运行成本和延长接地引下线使用寿命等方面均具有很强的实用性。
Traditional grounding down lead has defects of corrosion easily and too hard material texture. This paper presents the grounding wire galvanized steel strand for instead of round steel and designs installation process. And then the steel wire cross-sectional area is determined by thermal stability calculation. Example results show that the optimized design scheme has advantages of simple installation and low cost. At the same time. it has practicability of reducing the transmission line maintenance workload, operation cost and prolonging the service life of grounding down lead.
