空管雷达站避雷针研究与设计
|
摘要
针对空管雷达站经常遭受雷暴、强风等恶劣天气环境,架设的避雷针需满足雷达遮蔽角很小的特点,综合考虑上述情况,研究设计了一种细长型、小遮蔽、抗强风的避雷针。并利用ANSYS软件对设计的避雷针进行有限元仿真分析,仿真结果表明:该避雷针能够承受80 m/s的强风,且安全系数较高,设计的避雷针可以在空管雷达站推广使用。
According to the characteristics of air traffic control radar station, such as harsh natural environments like strong breeze, high lightning strike risk, and the lightning rod should meet the requirement of small radar cover angle. With overall consideration of the above situations and a kind of lightning rod of slender shape, small shelter, strong wind-resistance is designed. The finite element analysis is carried out on the designed lightning rod by using ANSYS software, the simulation results show the designed lightning rod can withstand strong winds of 80m/s with higher safety coefficient. The designed lightning rod in this paper can be widely used in the ATC radar station.
