摘要超导磁体的失超检测与保护是超导电力技术实用化的一个重要课题。为了实现对超导储能混合磁体的失超检测与保护, 本论文根据混合磁体的特点及结构, 在现有有源功率检测的基础上, 提出了一种针对超导混合磁体的电压校正电路, 通过对混合超导磁体上产生的失超信号进行隔离、放大、滤波以及比较等, 实现失超信号的检测。设计并完成了失超检测系统硬件电路的制作与调试。通过搭建高温超导线圈的实验装置, 在高温超导储能磁体上进行失超检测的实验研究, 得出了电压矫正前后的线圈电压波形。给线圈分别以不同速度充电, 研究充电速度对阀值电压、失超的起始点及临界电流的影响。实验线圈电压波形表明, 该失超检测系统能及时、有效地检测超导混合磁体失超的发生。

Abstract：Quench detection and protection of superconductor is a key problem for the practical application of superconducting electric power technology. In order to achieve the quench detection and protection of superconducting energy storage hybrid magnet, according to the characteristics and structure of hybrid magnet, voltage correction circuit of superconducting energy storage hybrid magnet was proposed based on existing active power detecting method. In this system, partial active power detecting method was adopted and the quench detection came true by isolating, amplifying, filtering and comparing the quench signal etc. The production and debugging of the hardware circuit of quench detection system is completed. Through the configuration of experimental device of high-temperature superconducting coil, the study of the quench detection on high-temperature superconducting energy storage system is conducted. The waveforms of the coil voltage were acquired before and after the calibration of the coil voltage. When coil was charged at different speeds, the effects of charging speed on quenching threshold voltage, quenching starting point and critical current were researched. Experiments waveforms of the coil voltage confirmed that the quench detection system can promptly and effectively detect hybrid superconducting magnet quench.
