摘要
以某实际仿真线路为实例建立了上字型杆塔仿真模型,通过仿真其安装单相、两相和三相不同避雷器组合,分析了避雷器在不同安装方式下对杆塔的多重因素的影响。最终得出35kV上字型杆塔以两边相同时安装线路避雷器防雷效果最佳。工程实践表明,研究成果应用于实际的防雷工程中具有良好的效果。
The lightning protection system of 35 kV overhead lines is analyzed. Based on the model of ＇shang＇ shaped towers,through the simulation of the installation of single-phase, two-phase and three-phase lightning arrester combination, the different impact of the installation on the lightning withstand level, flashover phases of insulators and lightning impulse overvohage are analyzed. The results show that installing line arresters on three phases or two side phases is the best choice. Engineering practice shows that the research results have a good effect in the actual lightning protection engineering.
