摘　　要：广播电视发射台通常位于辽阔的郊区地带,它们是高大的建筑物,因此更容易受到雷击的影响。特别是在雷雨季节,发射台的防雷问题变得尤为关键。以云南省曲靖市马龙区广播电视发射台防雷接地系统改造为实例,结合工作实践,介绍防雷接地系统改造中规划设计、材料采购、现场施工、节点焊接以及数据测试等环节的具体工作内容。Radio and television transmission stations are usually located in vast suburban areas and are tall buildings,making them more susceptible to lightning strikes.Especially during thunderstorm seasons,the lightning protection of the transmitting stations becomes particularly crucial.Taking the reconstruction of the lightning protection earthing system of the radio and television transmitting station in Malong district,Qujing city,Yunnan province as an example,combined with the work practice,this paper introduces the specific work contents of the planning and design,material procurement,on-site construction,node welding,data testing and other links in the reconstruction of the lightning protection earthing system.
