Abstract
The basic electrical insulation design of 2.5 MJ conduction cooling high temperature superconducting magnetic energy storage (HTS SMES) have been studied in this paper. The high voltage is generated both ends of magnet of HTS SMES by quench or energy discharge. Therefore, the insulation design of the high voltage needs for commercialization, stability, reliability and so on. In this study, we analyzed the insulation composition of a HTS SMES, and investigated about the insulation characteristics of the materials such as Polyimide, Al2O3 , GFRP and vacuum at cryogenic temperature. Base on these results, the basic insulation design for 2.5 MJ conduction cooling HTS SMES was performed.
