摘要
近年来随着通信技术、计算机技术、网络技术的发展和广泛应用,大多数水文站配备了气象计算机、通信电台、自动化测验设备等电子设备。这些弱电设备耐雷水平低,雷击概率加大,造成了较大的经济损失,水文站防雷日益成为重要而紧迫的课题。本文探讨了雷击的危害,防雷的基本方法,提出了水文站防雷应采取的措施和具体要求。
Lightning protection is an old and serious subject. With the rapid development and widely use of communication, computer and network technology, many gauging stations are equipped with computer, broadcasting station,auto - test apparatus,and other electronic facilities in the recent years. These facilities just can bear little part of the electric current produced by lightning, and frequent suffering of lightning will raise the economic losses. So how to avoid the damage of lightning in gauging station becoming an important and urgent subject. This article dissertated the harm and basic avoiding method of lightning, and also raised the relevant measures and demands of avoiding lightning in gauging station.
