自动气象环境监测站雷电过电压的抑制措施

Lightning over-voltage protection for automatic meteorological environment monitoring station

通过分析自动气象环境监测站的结构及雷电过电压入侵途径及其破坏作用,提出采用可靠的接地连接以防止雷电反击,使用屏蔽线缆以阻抗电磁脉冲,给电源系统、通信线路、传感器和采集器安装电涌保护器以抑制雷电过电压,为保证自动气象监测站正常可靠地运行提供实时的气象数据并发出预警信息.

By analyzing the structure of the automatic meteorological environment monitoring station and the invading channel as well as the damaging effect of the lightning over-voltage, the paper points out that the reliable grounding joint should be used to prevent ground lightning counterattack;the shielding cable should be used to protect against electromagnetic pulse;the power supply systems, communication lines, collectors and sensors should be installed with SPD to inhibit the lightning over-voltage. All these can ensure the station＇s normal and reliable operation, providing the real-time meteorological data and the warning information.
