光纤光栅温度监测仪在变压器热点远程监测中的应用

The Application of a Fiber Bragg Grating Temperature Detector in the Long-Distance Surveillance of Transformer Hotspots

介绍了一种新型光纤光栅温度监测仪用于变压器热点的温度监测,仪器采用先进的光纤光栅传感技术,具有不受电磁干扰、远程监测、精度高等优点,尤其适合变压器这种高压、强磁场的环境。在多个变电站投入使用,取得令人满意的测量效果,较好地解决了传统变压器测温设备测温不准的缺陷。

A transformer is a key equipment of an electrical system and its long-term online surveillance is quite significant. This paper introduces a new fiber Bragg grating temperature detector to surveil the temperature of the a transformer hotspot, in which we employ an advanced FBG sensing technology,and which has such positives as electromagnetic interference immunity, long-distance surveillance and high accuracy, especially suitable has been for such scenario as high voltage and strong magnetic field. It put into practice in many substations and the satisfactory results has been achieved, and it is a better the solution to the problem of the inaccuracy of other traditional temperature detectors.
