Thermal Analysis on Cryocooler Cooled High-Tc SMES Magnet

Abstract:

A model high-Tc Super-conducting Magnet Energy Storage (SMES) magnet, which is winded with high-Tc super-conducting Bi-2223 trip, is cooled by GM cryo-cooler. The SMES cooling feature is investigated. It took about 17 hours to reach the minimum temperature for the SMES cooling, and its axial temperature difference is 2.8 K, the radial temperature difference is less than 1 K. The thermal contact resistance results in the resource of larger axial direction temperature difference. By improved, the cooling time is about 25 hours for the cryo-cooler cooled 35kJ SMES magnet, its axial direction temperature difference is 0.4 K. At loading 140 A direction current, the magnetic density is 4.5 T, no temperature rise is observed. At loading 60 A alternating current, the upside temperature rise of 35kJ SMES magnet is about 5 K. The 35kJ SMES magnet has been operated stably 480 hours.
