乐平市国家站防雷整改的措施与分析

Measures and analysis of lightning protection rectification of Leping national station

为了减少或避免乐平市观测站的雷击事故,文章针对乐平市地面气象观测站防雷安全隐患,根据观测场各仪器、设备布局与相关防雷措施提出了整改思路。通过将232/485等通信线路更换成光纤通信、在强雷电来临之前切断市电,以及采用锂电池供电、加装避雷针、严格内外网接地、屏蔽和安装浪涌保护器、等电位连接等方法进行防雷改造后,观测场的仪器设备在多次强雷电过程中得到了有效保护。

In order to reduce and avoid lightning accident of Leping observation station,aiming at the hidden danger of lightning protection safety of Leping ground meteorological observation station,according to the layout of instruments and equipment in observation field and relevant lightning protection measures,the rectification ideas are put forward.By replacing 232/485 communication lines with optical fiber communication,cutting off the power supply before the strong lightning,using lithium battery power supply,installing lightning rod,strictly grounding the internal and external network,shielding and installing surge protective device,equipotential connection and other methods for lightning protection transformation,the instruments and equipment in the observation field have been effectively protected in the process of many strong lightning.
