摘要：為滿足超導直流能源管道精準的測溫需求，保證超導電力和液化天然氣混合輸運的目標，設計了一種低溫工況平臺，在混合工質溫區(85～90 K)對光纖光柵傳感器進行溫度傳感特性研究，通過 PT100 鉑電阻對光纖光柵進行準確的溫度標定，所測溫度最大值偏差小于0.1K。搭建了 10 m 超導能源管道樣機，實測在不同通流情況下，PT100 鉑電阻測溫波動較大，而光纖光柵測溫不受影響。在突然升溫過程中，PT100 鉑電阻測溫平均響應時間為2.43 s，光纖光柵傳感器測溫響應時間為0.47 s。

Abstract: In order to meet the needs of accurate temperature measurement of superconducting DC energy pipelines, and to ensure the goal of hybrid transport of superconducting power and liquefied natural gas. In this paper, a low-temperature platform is designed to study the temperature sensing characteristics of the fiber grating sensor in the temperature region of mixed working fluid (85～90 K), and the temperature of the fiber grating is accurately calibrated by PT100 platinum resistance, and the maximum deviation of the measured temperature deviation is less than 0.1 K. Furthermore, a 10 m prototype of a superconducting energy pipeline is constructed and tested under various flow conditions. The results show that the temperature measurement by PT100 platinum resistance experiences significant fluctuations, whereas the fiber grating sensors remain unaffected. In the process of sudden temperature rise, the average response time of PT100 platinum resistance is 2.43 s, and that of fiber grating sensor is 0.47 s.
