摘要
电力设备的热效应是引发变电站多种故障和异常的重要原因。为了加强对无人值守变电站的全貌监视,尤其是对其电力设备温度的在线实时监控,构建了具有红外测温功能的远程图像监控系统,实现了过热设备的报警联动。文章从红外测温技术、红外测温在图像监控中的实现两方面展开论述,介绍了该系统的技术原理与实现方法。
The heat efficacy is an important cause to produce power appliances failure and abnormity in transformer substation. For strengthening the panorama monitoring of unattended transformer substation, especially for the online temperature monitoring of power appliances, the video monitoring system that using infrared temperature measurement needs to be constructed, the alarm function to an over heating appliances are realized as well. The infrared temperatures measuring technique and its application of using it to video monitoring system are discussed in this paper, and the techno-principle and realization method are introduced.
