摘要
针对小型实验NbTi超导磁体,通过建立螺线管线圈正常态区域传播的数学模型来定性描述其三维传播特性,并就磁体失超的实验波形做深入分析,阐述绕组匝间及层间的热传导效应对磁体失超传播速度的影响,掌握实验磁体失超过程中的内阻变化曲线,为磁体的失超信号检测与保护奠定良好的理论基础。
It＇s very important to master the magnet＇s quench transmitting property when we research the NbTi magnet＇s quench protection. A mathematical model of the magnet＇s quench transmittion was established to describe the. three - dimensional quenching property, we particularly analyzed the experimental curve when the magnet＇ quench happending, and expatiated the effect between the heat exchange and quench transmitting velocity. The changes of magnet＇s inner resistance were obtained to establish good academic foundation for the magnet＇s quench detection and protection.
