大气电场仪主要功能为实时测量记录地面上的静电场值与变化率。保护人身安全：在易发雷击事故的场合，提前预告雷暴的来临，减少雷击伤害事故的发生。在易发水灾场合，可以超前预告暴风雨的来临。保护环境与财产安全：在雷电来临之前，可采用适当措施来限制风险。例如在敏感的通讯电子场所，采用自动隔离供电系统，启动备用UPS电源来确保设备的安全；选用 具有自动切换功能的开关，来启动或停止重要或精密的机器设备。The main function of the atmospheric electric field instrument is to measure and record the electrostatic field value and rate of change on the ground in real time.Protection of personal safety: In the occasions prone to lightning strike accidents, advance notice of the coming of thunderstorms to reduce the occurrence of lightning injury accidents. On flood-prone occasions, the storm can be forecasted ahead of time.Protect the environment and property safety: Before lightning strikes, appropriate measures can be taken to limit the risk. For example, in sensitive communication and electronic places, an automatic isolation power supply system is used to start the standby UPS power supply to ensure the safety of the equipment; a switch with automatic switching function is selected to start or stop important or sophisticated machinery and equipment.
