摘　　要：采用有源功率检测法,设计和制作了超导混合储能磁体能量储存系统的失超检测中的电压隔离校正装置。该装置用于隔离超导线圈的干扰信号,以及消除串联线圈电感分量,是混合磁体失超检测中的重要环节。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,验证了本实验装置可行性与合理性。The active power detection method is used to design a voltage isolation and calibration device of quench detec- tion for the superconducting hybrid magnet energy storage system. The device is an indispensible part of hybrid magnet quench detection, which is utilized for the isolation of interfering signals from superconducting coil and the elimination of in- ductance component of the coil with series connection. Through the configuration of experimental device of high-temperature superconducting coil, the quench detection on high-temperature superconducting energy storage system are studied. The waveforms of the coil voltage are acquired before and after the calibration of the coil voltage to verify the feasibility and ration- ality of the experimental device.
