Temperature Measurement under High Voltage and Compensation Method

针对高电压、强磁场环境中的温度测量,提出了基于光纤温度传感器的温度测量方案,设计了新型的光纤温度传感器,通过双波长光源和补偿回路的设计,提高了测量精度和稳定性。理论证明和多次试验验证表明,该方案能够实现精度较高的温度测量,并且具有绝缘性好、抗电磁干扰能力强、成本低、体积小、便于安装等优点。

For temperature measurement under the environment of high voltage and strong magnetic interferences, we proposed a solution based on optical fiber temperature sensor. We designed a new optical fiber temperature sensor, which significantly improved the accuracy and stability of temperature measurement by utilizing double wavelength light source and designed compensation loop. Mathematical simulation and experiment verify the high accuracy of the optical fiber temperature sensor. Moreover, the optical fiber temperature sensor has good insulation as well as excellent anti magnetic interference property with small volume, easy installation and lower cost.
