Abstract
We designed a persistent current switch consisting of Nb3Sn superconducting wire for Superconducting Magneto-Hydro-Dynamic Propulsion Ship (MHDS). Nb3Sn has Tc higher than NbTi, which is commonly used for the conventional persistent current switch, and thus is expected to show a higher stability against the disturbance. We therefore performed numerical simulations for the heat transfer in a 10kA-class Nb3Sn persistent current switch by using a finite element method. The results of switching performance will be presented based on the computer simulation for temperature distribution during the heating and cooling cycle. We also present the estimated time for the transition from the superconducting to normal state (off-state) and vice versa (on-state).
