基于滚球法的航向天线阵防雷评估与实例分析

池州九华山机场 ILS 系统 13 号航向信标天线阵抬升基座后,相应 ZGU-200-3(TY) 优化避雷针未作调整,为确保防雷设施保护有效,本文依据民用航空通信导航监视设施防雷技术规范的滚球法对航向天线阵防雷部分进行设计评估和调整。首先,通过数据计算分析跑道两端航向天线阵是否在接闪带和 ZGU-200-3(TY)优化避雷针的保护范围内;其次,根据技术规范核查防雷工程的规范符合性情况;最后,通过理论和实际因素分析为本场航向天线阵防雷设施存在的问题提出相应解决方案。

Lightning Assessment and Instance Analysis of Localizer Antenna Based on Rolling Sphere Method

After uplift the base of No. 13 LOC localizer antenna of ILS system in Chizhou Jiuhuashan Airport, there is no adjustment on ZGU-200-3 (TY) optimized lightning rod. In order to ensure the effectiveness of lightning facilities protection, the lightning part of localizer antenna is assessed and adjusted according to the rolling sphere method. First of all, through the data analysis of localizer antenna on both ends of the runway to ensure whether in the protection zone of lightning belt and ZGU-200-3 (TY) optimized lightning rod or not. Secondly, check the specification compliance of lightning protection engineering according to the technical specification. Finally, through the theoretical and practical factors, the issues of localizer antenna are analyzed and the solution is proposed.
