【摘要】 在大坝安全监测自动化系统(以下简称“系统”)的应用中,雷电和电磁波干扰往往会导致“系统”产生严重故障,为保障“系统”正常可靠的运行,应对“系统”采取有效的防雷保护措施。对“系统”遭受雷击损害的主要原因以及雷电可能的侵入途径进行了分析,针对福清市东张水库大坝“系统”遭受雷击的原因,对“系统”的防雷保护技术作了相应介绍。实践证明,东张大坝经采取针对性防雷措施后,这两年监测仪器很少遭受雷害。更多还原

【Abstract】 In the application of dam- safety monitoring systems, thunder and eletromagnetic waves oftencause serious problems. In order to safeguard reliable operation of the systems, effective measures should betaken. The author analyzes the main reasous and possible paths the systems are exposed to damages by thunderand electromagnetic waves. Taking Dongzhang Reservoir as an instance, the author also introduces correspondingmeasures. Thanks to these measures, the system is seldom affected by thunder and electromagnetic waves overthe last two years.更多还原
