“鹰眼”雷电预警系统在地震台站的应用

地震观测仪器防雷击是保证仪器正常工作的首要难题之一。目前,虽然很多台站对仪器做了多级保护的防雷工作,但未起到提前有效的防护作用。本文介绍的"鹰眼"雷电预警系统主要实时监视一定尺度空间的电场值和雷电波,当系统监测值达到设定的预警条件参数,则自动报警,可提前切断仪器与外界的连接,有效预防雷击。

Application of "eagle-eyed" thunder and lightning early warning system in seismic station

The earthquake off-carriage instrument＇s against thunder stroke guarantees one of instru ment normal work most important difficult problems. Although at present the multistage lightning proof works for the instrument have been done in many stations, the protection can not effectively work ahead of schedule. In this article, an ＂＇eagle-eyed＂ thunder and lightning early-warning system is introduced. Its main function is monitoring the electric field value and the thunder electric wave in certain criterion space in real-time. When the monitoring value achieves the preconcerted of early warning condition parameter, the system gives an alarm automatically. It guarantees to shut off the instrument and the outside connection ahead of time, and effectively prevent the instrument from lightning strike.
