Optimum design of fiber Bragg grating real-time on-line temperature detecting sensor for power cable
摘要
Abstract
Fiber Bragg grating (FBG) temperature sensor system for high and extra high power cable was developed. Starting from theoretical model, FBG sensing mechanism was proposed to establish a framework for optimal design. Bonded encapsulation structure was proposed through the optimum design for the encapsulation structure of FBG temperature sensor. Using aluminum plate was proposed as encapsulating substrate material through the optimum design for linearity. The method of encapsulating with small size of 10 mm×40 mm was proposed through the optimum compensation design for external stress field. Then, water experiment on FBG temperature sensor and comparative experiment on FBG temperature systems were conducted, and the performance and feasibility of the system was discussed. Finally, FBG temperature on-line monitoring system was applied to actual projects, in which the resolution is up to 0.1 ℃, the accuracy reaches ±0.5℃, and the temperature range is -30-200℃.关键词
