中波发射台天馈系统的接地改造与防雷实践

Practice of Grounding Modification and Lightning Protection for Antenna Feed System of Medium Wave Transmitter

中波发射台天馈系统接地改造和防雷工作具有一定的复杂性,只有找到防雷与接地改造的重点,才能达到理想的工作目的。改造工程开展过程中,需要合理融入现代防雷技术,做好系统分析工作,从而有效发挥防雷作用。根据目前的实际情况来看,中波发射台天馈系统在日常运行中会受到雷雨天气和周边建筑的影响,只有对防雷设计体系进行逐级完善,保证天馈系统符合防雷要求,增强避雷带的规范性,才能保证信号传输的完善性。在中波发射台日常运行中,电源系统和通信系统会直接影响中波发射台的工作质量,通过制定安全防护体系,保证各系统的稳定运行,提高工作人员的作业安全性。

The grounding transformation and lightning protection work of antenna feed system in medium wave transmitting station is complicated.Only by finding the emphasis of lightning protection and grounding transformation can we achieve the ideal work purpose.In the process of renovation,it is necessary to integrate modern lightning protection technology reasonably and do a good job of system analysis,so as to effectively play the role of lightning protection.According to the actual situation at present,the antenna feeder system of medium wave transmitting station will be affected by thunderstorm weather and surrounding buildings in daily operation.Only by improving the lightning protection design system step by step,ensuring that the antenna feeder system meets the lightning protection requirements and enhancing the standardization of lightning protection zone can the signal transmission be perfect.In the daily operation of the medium wave transmitting station,the power supply system and communication system will directly affect the working quality of the medium wave transmitting station.By establishing a safety protection system,the stable operation of each system can be ensured,and the working safety of staff can be improved.
