面向极端环境的布拉格光栅植入复合绝缘子芯棒温度与应力特性
Temperature and Stress Characteristics of Composite Insulator Rods Implanted with Bragg Grating for Extreme Environment
摘要
Abstract
The author conducted research on the temperature and stress characteristics of Bragg grating in-sulators.The following tasks have been completed:1)A temperature and stress testing system for Bragg grating insulators was established by slotting the insulators and laying fiber Bragg gratings at different points,thereby achieving real-time monitoring of Bragg grating insulators.2)Temperature and stress calibration experiments were conducted on the Bragg grating insulator,and the quantitative numerical re-lationship between the grating center wavelength of the Bragg grating insulator and temperature and stress was determined.The research results indicate that there is a good linear relationship between the changes in stress and temperature and the central wavelength of the grating,which can be used for on-line moni-toring of power transmission equipment.关键词
