摘　　要：广播内容的播出质量依赖于中波广播发射台的持续稳定运行。为捕获更广泛的信号资源,发射台通常设计在较高位置且周边无其他建筑物遮挡,这导致其在防范雷电侵袭方面面临着更为严峻的挑战,增加了遭受雷击的风险,进而影响广播信号的正常传输与接收。通过对实际案例的分析,全面评估中波广播发射台的雷电防护现状,深入分析潜在问题,提出具有针对性的雷电防护技术方案,为相关行业人员提供参考。The broadcast quality of broadcast content depends on the continuous and stable operation of the medium-wave broadcast transmitting station.In order to capture a wider range of signal resources,the transmitting station is usually designed in a higher position without other buildings around it,which leads to more severe challenges in preventing lightning attacks,increasing the risk of being struck by lightning,and further affecting the normal transmission and reception of broadcast signals.Through the analysis of actual cases,this paper comprehensively evaluates the lightning protection status of China-Poland broadcasting transmitting station,deeply analyzes the potential problems,and puts forward targeted lightning protection technical schemes to provide reference for relevant industry personnel.
