摘要
结合云南省文山州中小河流水文监测系统中心站周围的环境因素、雷电活动规律等,系统分析了水文自动测报系统的引雷途径,本着安全、经济、实用的原则,在遵循国家有关防雷标准的基础上,提出了切实可行的建筑物外部防雷和内部防雷设计方案。水文自动测报系统外部防雷设计侧重考虑避雷针(带、网)、引下线、接地网等方面,内部防雷设计则主要考虑电磁屏蔽、等电位连接、避雷器(SPD)3部分。并且,参考IEC国际电工委员会的有关防雷技术标准,提出了水文自动测报系统设备防雷地、工作交流地(N线)、静电地、屏蔽地、绝缘地等共用一个接地体的方案,既保证了防雷设备的安全性,又节约了工程投资。
In the consideration of environmental factors and lightning activity in the surrounding area of the central station of hydrological automatic measurement system for middle and small rivers in Wenshan Prefecture of Yunnan Province, the approach of artificial-triggered lightning for the system is systematically analyzed, and based on the principles of safety, economy, practi-cability and compliance with national standards, the feasible lightning protection schemes of external and internal structures are put forward. The external lightning protection is mainly realized by lightning rod （belt, network）, down lead, grounding grid while the inner lightning protection is mainly realized by electromagnetic shielding, equipotential connection, lightning arrester （ SPD） . In addition, a common grounding body scheme shared with lightning protection body, work exchange ground body, static electricity ground, shielding ground, insulating ground is put forward, which not only safeguard the safety of lightning protection device, but also save the investment.
