地震台站仪器设备防雷改造实践

摘要
通过对重庆地区地震台站雷击情况分析,总结出电源线路及通信线路引雷是雷电入侵仪器设备的主要原因,结合"十五"地震台数字化仪器的特点,设计出完善的地震台仪器设备防雷方案,使用专用防雷设备,可以有效防止雷灾发生或减轻雷灾的损失。
A large number of digital seismic instruments have been installed in the seismic stations during the 12th five-year plan. Some of statistical data show that the lightning has been an endangered factor to the digital equipment and information systems in seismic stations. A lot of seismic stations are in the environment of the lightning. At the some times,the seismic observation equipment are microelectronics devices and are just very sensitive to the lightning. In order to protect the seismic equipment from the lightning,we designed the protective schemes and special lightning protection equipment.
