A fluorescent optical fiber temperature measurement method and system for a transformer

Abstract

The application discloses a fluorescent optical fiber temperature measuring method and system for a transformer, and relates to the technical field of optical fiber temperature measurement. The method comprises the following steps: calibrating fluorescent optical fibers at different preset temperatures, and arranging the calibrated fluorescent optical fibers at preset temperature measuring points of the transformer; acquiring fluorescent signals and fluorescent time sequence signals of the preset temperature measuring points by using the fluorescent optical fibers, and performing attenuation characteristic analysis on the fluorescent time sequence signals to obtain attenuation signals; performing signal interaction on the fluorescent signals, the fluorescent time sequence signals and the attenuation signals to obtain fluorescent interaction signals of different types; fusing the fluorescent interaction signals to obtain fused attention signals; monitoring abnormal temperature points in a temperature curve and abnormal coordinate intervals where the abnormal temperature points are located; and generating a temperature gradient distribution map based on temperature signals of the preset temperature measuring points measured in real time. The application can realize accurate detection of temperature changes, can quickly respond to temperature changes, and ensures real-time performance and accuracy.
