雷击后的自动气象站故障及修复方法

Fault and maintenance of automatic weather station after struck by lightning

针对自动气象站的气象数据采集器耐过压、过流的能力较低、对雷电袭击的抵御能力较弱的情况,本文就Ⅱ型自动气象站雷击造成的常见故障维修过程,以3个工作实例介绍排除雷击故障过程中的分析思路,故障判断方法和排除故障具体步骤,以便在遭受雷击后自动气象站出现故障时,能够得到及时地排除,减少自动站数据缺测的时次,以提供准确完整的气象数据。

Regarding to the problems that automatic weather station has low capacity to resist overvoltage,overcurrent and lightning attack,based on maintenance process for common faults of automatic weather station Ⅱ caused by lightning,this paper introduces maintenance thought,troubleshooting methods and specific steps by taking three working examples,which can solve faults in time after struck by lightning,reduce times of missing data and improve the integrity and accuracy of weather data.
