摘　　要：为保证高温超导线圈稳定运行,利用基于拉曼散射技术的分布式温度传感器对其进行温度检测而提前预判失超状态是当前的研究热点之一,通过观测温度变化率为提高检测速度提供一种新的思路。将6.2 m的单模光纤缠绕并固定于超导线圈的上表面进行失超温度检测,实验得出了失超后线圈温度分布规律,并验证了该方法的可行性。In order to ensure the stable operation of high-temperature superconducting coils, it is one of the current research hotspots to use distributed temperature sensors based on Raman scattering technology to detect the temperature and predict the quench state in advance, by observing the temperature change rate to provide a new idea to improve the detection speed. A 6.2 m single-mode optical fiber was wound and fixed on the upper surface of the superconducting coil for quenching temperature detection. The experiment obtained the temperature distribution law of the coil after quenching and verified the feasibility of the method.
