为了实现对高压电气设备的非接触温度监控, 设计了中远距离(0-1.5 m)非接触荧光光纤测温系统.该系统利用稀土荧光材料的荧光温度特性, 通过测量物体表面荧光物质的受激荧光寿命获得物体的温度信息;通过增加聚光透镜和聚光锥罩, 提高探测器接收到的光能量.实验获得荧光强度曲线及被测对象温度, 实现了对温度的非接触实时测量, 测量误差低于1℃, 满足高压电气设备的非接触温度监控要求.

To realize the non-contact temperature monitoring of high voltage electrical equipment, a non-contact (0-1.5 m) fluorescence fiber temperature measurement system was designed. Using the relation between fluorescence and temperature of rare earth materials, temperature measurement was achieved by measuring the excited fluorescence lifetime of the fluorescent material which was attached on the object. The analysis indicates that the received light energy can be increased through adding a converging lens and a converging cone. In the experiment, the fluorescence intensity curve was obtained, and the temperature was aquired according to the relation of fluorescence lifetime and the temperature of the measured object. The measurement error is less than 1 ℃, ensuring its application in high-voltage environment.
