摘要
广播发射台一般建在海拔高、地势空旷的地方,受到雷电攻击的概率较大。一旦遭遇雷电袭击,轻则广播中断,重则需要耗费大量的人力、物力和财力进行维修,还有可能会引发人员伤亡。因此,从常见的雷电类型入手,探讨做好中波广播发射台的防雷保护的必要性,研究相关的防雷保护技术,提出有针对性的防雷保护策略,旨在为中波广播发射台防雷保护工作的顺利开展提供有效参考。
Radio transmission stations are generally built in high altitudes and open terrain,and the probability of being attacked by lightning is greater.Once it is struck by lightning,the broadcast will be interrupted,and at the worst,a lot of manpower,material and financial resources will be spent on repairs,which may cause casualties.This article starts with common types of lightning,discusses the necessity of doing a good job in the lightning protection technology of medium wave broadcasting transmitters,and discusses related lightning protection technologies,and finally puts forward several targeted lightning protection strategies.It aims to provide some effective references for the smooth development of lightning protection work of the medium wave broadcasting transmitting station.
