雷电对人类的危害由来已久,但长期以来,人们只注意到对建筑物的影响,事实却不然。据统计表明,在雷电灾害中,以雷电对精密电子设备的损坏为最大。近年来,民航无线电通信导航设备受雷击的事件时有发生,严重影响通信导航设备的正常运行,给飞行安全带来危害。因此,防雷逐渐引起从事无线电通信导航设施设计、管理和维护的工程技术人员的重
Thunder and lightning have long been a danger to humanity, but people have only noticed the impact on the buildings for a long time. However, it is not true. According to statistics, in the lightning disaster, lightning damage to the precision of electronic equipment is the largest. In recent years, frequent occurrences of lightning strikes on civil aviation radiocommunication and navigation equipment have seriously affected the normal operation of communications and navigation equipment, posing a threat to flight safety. As a result, lightning protection has gradually led to the heaviness of engineers and technicians engaged in the design, management and maintenance of radio communication navigation facilities
