Abstract

The electrical insulation design of 600 kJ conduction cooled high temperature superconducting magnetic energy storage (HTS SMES) has been studied in this paper. High voltage is generated to both ends of magnet of HTS SMES by quench or energy discharge. Therefore, the insulation design of the high voltage needs for stability and reliability to allow commercialization. In this study, we analyzed the insulation composition of a HTS SMES, and investigated about the insulation characteristics of materials such as Kapton, AlN,Al₂O₃, GFRP and vacuum at cryogenic temperatures. Based on these results, the insulation design for 600 kJ conduction cooled HTS SMES was performed.
