In this paper, the detection of lightning arresters in 100 colleges, primary and secondary schools in Beijing from 2010 to 2016 was analyzed. The results showed that the frequencies of lightning protection hidden dangers in 100 primary and secondary schools were the following: uninstalled surge protective device (damage) accounted for 73％, unearthed internal (outside) equipment was 62％,equipotential connection (potential connection network) accounted for 41％, lightning belt binding phenomenon accounted for 30％, no direct lightning protection device accounted for 21％; overhead flying line, the arrester belt lodging, unused cross connection and lightning belt failing to protect the building completely (not in the protection range of direct lightning) accounted for 17％, respectively; the number of the earth connecting cable (ground resistance overproof, oversize, or disconnection) and the breaking of the lightning belt each accounted for 11％. Hence, based on the requirements of the standard, safe,feasible, and pertinent rectification opinions and countermeasures are put forward to provide a reference for schools to improve the campus lightning protection facilities and strengthen their lightning protection work.%对2010-2016年北京市100所大中小学校避雷装置检测情况进行分析,结果表明:100所大中小学校防雷隐患出现频率最高的依次是:未安装电涌保护装器(损坏)占73％;内(外)设备未接地占62％;等电位连接(电位连接网络相连)占41％;避雷带捆绑现象占30％;无直击雷防护装置占21％;架空飞线、避雷带倒伏、未用跨接、避雷带不能对建筑物进行全面防护(不在直击雷保护范围内)各占17％;接地引下线根数(地阻值超标、过大、断开)、避雷带断开各占11％.按规范要求,提出安全可行、有针对性的整改意见和对策措施,以便为学校完善校园防雷设施和强化其防雷安全工作提供参考.
