摘要
石油储存库区地域开阔,易受雷击,是油库安全的一大隐患;为了采取更好的防雷措施,减少雷电造成的损失,人们必须了解有关雷电流的一些重要参数。文章介绍了一种适用于大型石油库的雷电流采集系统,该系统以Ro-gowski线圈作为雷电流传感器,以AVR单片机为核心,以CAN总线和GPRS技术实现数据传输;具有成本低廉,易于安装的特点。该系统应用于某大型石油库,取得了令人满意的效果。
Lightning strike is the major safety risk for oil tanks located on a vast flat area. In order to take better measures to reduce losses caused by lightning,it is necessary to learn more about some of the important parameters of lightning. Based on the investigation of the characteristics of the oil storage base,a CANBUS-based lightning current acquisition system,with Rogowski coil current sensor and AVR microcontroller,is introduced in this paper. The system is low cost,high performance and easy to install and use.
