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。文中针对超导储能系统的特点,设计了一套用于超导储能(SMES)磁体的失超检测系统。该系统采用有源功率检测方法,通过对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。实验结果表明,该失超检测系统能够及时准确的检测到失超信号,为超导储能系统的失超保护提供了可靠的前提条件。The quench detection and protection of superconductor are a key problem in the practical application of superconducting electric power technology. This paper designed the quench detection system applied in SMES magnet based on the characteristics of SMES system. The active - power detection method was used and the quench detection came true by isolating, amplifying, filtering and eomraring the quench signal. The result shows that the quench detection system can timely and accurately detect the quench signal and provide the reliable precondition for quench protection.
