【摘要】 高温超导电缆、线圈和磁体的失超探测一直都是一个难点。利用基于光纤光栅传感技术的多光栅串温度监测系统，通过检测温度的实时变化为快速探测失超并准确找到失超点提供了一种新的方法。通过多次对高温超导带材失超探测实验，结果表明，在超导带材失超时，多光栅串会同时发生中心波长位移，表明带材温度变化可以被光栅串实时监测。通过理论计算和实验测定，验证了基于多光栅串探测高温超导失超的可行性，为后续的高温超导磁体和超导电缆的失超探测提供了一种新方法。更多还原

【Abstract】 Quench detection of HTS cables, coils and magnets has always been a challenge.A multi-grating string temperature monitoring system was used to detect the real-time temperature changes for rapid detection of quench and accurate detection of quench points to offer a new way based on fiber grating sensing technology.Through several quench detection experiments on HTS tapes, the results show that the center wavelength shift of multiple grating strings will occur at the same time when the superconducting tape quenches, indicating that the temperature changes of the tapes can be monitored in real time by the grating strings. Through theoretical calculations and experimental measurements, the feasibility of detecting HTS quench based on multiple grating strings is verified, which provides a method for subsequent quench detection of HTS magnets and superconducting cables.更多还原
