摘　　要：针对大多数地面数字电视补点站地处野外、位置偏远、供电环境不稳定的问题,结合南方频繁多变的雷雨天气,分析补点站机房供电和接地防雷现状,通过有效改进不间断电源的组合供电和防雷地网,探讨一种基于自复位不间断稳压电源的改进方案,确保无人值守补点站的广播电视安全播出。In view of the problems that most terrestrial digital TV supplementary stations are located in the wild,remote and unstable power supply environment,combined with the frequent and changeable thunderstorm weather in the south,this paper analyzes the current situation of power supply,grounding and lightning protection in the machine room of supplement stations,and discusses an improvement scheme based on self reset uninterruptible regulated power supply by effectively improving the combined power supply and lightning protection network of uninterruptible power supply,ensure the safe broadcasting of radio and television in unattended supplementary stations.

关 键 词：补点站 自复位不间断电源 标准化 接地防雷
