摘要
对铜与镀锌钢的性能和接地体最小截面进行比较分析;介绍了效果良好的铜接地体的放热火泥熔接的连接方式;提出铜材接地网实施的优化措施,并结合工程实践,对铜材接网及镀锌钢接地网进行了技术经济比较。论证了铜材接地网在技术和经济上的优势。
By analyzing the performance and comparing the minimum section area of grounding electrode of copper with galvanized steel, the connection method with exothermic fireclay fusion splicing of copper grounding electrode with good performance is introduced. Optimization method of copper grounding network is presented. Taking a practical engineering project as an example, technical and economic comparison of copper grounding network with galvanized steel grounding network is performed and the result shows that copper grounding network has advantage in technology and economy.
