摘要
新一代多普勒天气雷达作为重要、特殊的天气监测设备,对雷电防护的要求非常严格。根据宣城市新一代S波段多普勒天气雷达所在地的气象条件、雷电环境、地理环境等,综合考虑确定雷达塔楼和信息系统雷电防护等级,从直击雷防护、均压、屏蔽、等电位连接、安装电涌保护器等方面分析了雷达系统采取的综合防雷措施。雷达系统自运行以来未出现雷电灾害,证实了防雷措施合理、可行。
As an important and special weather monitoring equipment,the new generation Doppler weather radar has strict requirements on lightning protection.Based on the meteorological conditions of S band Doppler weather radar station in Xuancheng,lightning environment,geographical environment,the lightning protection level of radar tower and information system was determined.Comprehensive lightning protection measures were taken for radar system from direct lightning protection,voltage equalization,shielding,equipotential connection and installation of surge protector.Since radar operation,there has been no lightning disaster,which is proved that lightning protection measures are reasonable and feasible.
