关于水文缆道测流系统中的避雷技术的研讨

Research of lightening protection technology about cable way hydrometry

水文缆道测流是我国十九世纪五十年代以来的水文独创测流技术。几十年来发展较快,特别是近十年来水文缆道自动化测流系统的广泛推广应用,发展十分迅速,已建成五千余处测流缆道。但缆道设备遭雷击的问题又成为发展的主要障碍。本文将根据多年实践经验,较完整地提出一些缆道测流中的避雷方法的研讨,抛砖引玉,与水文同行共同解决此难题,以利水文测量现代化的快速发展。

Cable way hydrometry is an original creation technology since last 50s＇ in China. With a rapid development, it received widely application in cable way hydrometry automatic flow measurement system in 5racent years, It has been found 5000 sites flow measurement cable ways. The big trouble in automatic cable way operation is thunder storm for lightening protection. The paper illustrates several ways of lightening protection to open up new world of technical solution for supporting speedy forwarding in modernization of hydrological operation.
