摘要
针对中波广播发射台在雷雨天气条件下信号传输误码率大、影响信号传输质量的问题,文中开展了对其防雷系统的设计与安装研究。首先,设计了中波广播发射台防雷系统框架,然后选择电源系统分级防雷保护与防雷器,完成系统等位电网设计与安装。通过实例证明,安装防雷系统后,中波广播发射台的信号传输误码率显著降低,可有效促进传输质量的提升,同时保障发射台在雷雨天气的安全性,应用效果较好。
In response to the problem of high signal transmission error rate and impact on signal transmission quality of medium wave broadcasting transmission stations under thunderstorm weather conditions,this paper conducts research on the design and installation of their lightning protection system.Firstly,the lightning protection system framework for the medium wave broadcasting transmitter was designed,and then the graded lightning protection and lightning arrester for the power supply system were selected to complete the design and installation of the system̓s equipotential power grid.Through practical examples,it has been proven that the installation of lightning protection systems significantly reduces the error rate of signal transmission at medium wave broadcasting transmission stations,effectively promoting the improvement of transmission quality and ensuring the safety of transmission stations in thunderstorm weather.The application effect is good.
