| Abstract: | High temperature superconducting superconducting magnetic energy storage(HTS SMES) magnet cooled was studied through 5?W/20?K GM cryocooler. SMES magnet was wound by Bi 2223 superconducting coil with its height 110?mm, inter diameter 72?mm and outer diameter 112?mm. In HTS SMES magnet its temperature could reach 25.4?K after 16?h, its longitudinal temperature difference was 2.8?K, and its radial temperature difference was fewer than 1?K at equilibrium. The experiment demonstrates that this experiment setup and the cooled construction of HTS SMES magnet are feasible. The data are obtained for the analysis of HTS SMES magnet cryocooler cooled. |
