摘要
针对超导储能混合磁体的特点,设计了一套用于超导储能混合磁体的失超检测与保护系统。系统采用数字失超检测方法,利用高性能的数字采集卡NI-6224,快速可靠的检测到磁体失超;并通过卸能电阻可变的卸能回路实现磁体的失超保护,极大地加速了磁体电流的衰减,提高了移能效率,减小失超区的温升。
This paper designed the quench detection and protection system applied in SMES hybrid magnet hased on characteristics of SMES hybrid system. This quench protection system adopt digital quench detection system and rely on high-powered NI-6224 digital acquisiton card, so it can quickly and reliably detect quench in SEMS hybrid magnet. Discharge energy circuit adopting alterable discharge energy resistance greatly impove discharge effieidency and reduce volatilization of cooling medium.
