摘要:
输电线路杆塔接地网在外延、垂直接地等措施受限时常采用辅助降阻材料降阻,实际接地工程采用接地模块时缺少统一规范性指导,在应用时存在一些盲目施工、降阻效率低等问题。采用CDEGS软件针对新型辅助降阻材料——柔性石墨复合接地模块的接地特性进行仿真计算研究,针对“一”字型、方框型以及方框射线型接地网采用柔性石墨复合接地模块时的降阻效率进行计算,分析模块敷设位置、敷设密度、敷设方式、接地网面积等因素对接地特性的影响规律,针对实际输电线路采用柔性石墨复合接地模块降阻给出相应施工建议。
Abstract:
Auxiliary resistance reduction materials are often used to reduce the resistance when the extension and vertical grounding measures is limited in grounding grid of transmission line towers. Due to lack of unified application guidance onthe grounding modules in the actual tower grounding project, some problems occurred in application such as blind construction and low reduction efficiency. In this paper, the CDEGS software is adopted to simulate and calculate the grounding characteristics of a new auxiliary resistance reduction material- flexible graphite composite grounding module. The resistance reduction efficiency of flexible graphite composite grounding module is calculated for the "one" shaped, square shaped and square-ray shaped grounding grid. The effects of laying position, laying density, laying mode and grid area on the grounding characteristics are analyzed. Finally, the corresponding construction suggestions are given for the actual transmission line using grounding module to reduce the resistance. The conclusions of this paper can provide references for the lightning protection of transmission lines and the construction of the grounding grid of towers.
