水文自动测报系统防雷的探讨

水文自动测报系统若配备有线／无线（GSM，GPRS）双通道，可提高系统的可靠性，保证系统的畅通。然而，有线组网方式最致命弱点是防雷能力差，针对防雷问题，在实践中探讨其有效途径，论述接地装置的设计、安装中应注意的几个问题，并介绍在实践中电话线防雷从一级防护发展到三级防护，提高防雷的效果，有待在实践中，再认识，再提高。

Discussion on Lightning Protection Technology for Automatic System for Hydrological Data Acquisition and Transmission

Automatic system for hydrological data acquisition and transmission that applies wired and wireless dual channel communication modes can not only improve system reliability, but also guarantee the smooth communication of system channels. But the greatest weakness of wired networking mode is lightning protection performance. Directing towards lightning protection, issues for grounding device design and installation that should be noticed are discussed. Then the author introduces that lightning protection for telephone line has been developed from one protection to triple protection. The results for lightning protection still be waited for recognition and more improvement through practice.
