초록
This paper deals with cryogen, which is used solid nitrogen to keep the operating temperature of High Temperature Superconducting (HTS) synchronous machine. To make the solid nitrogen of liquid nitrogen, liquid helium (LHe) passes into and cools the heat exchanger to its own temperature. Two types of heat exchangers are designed and manufactured to make the solid nitrogen, and temperature characteristics of those compare with each other. The rotor cooled by latent heat of solid nitrogen and it is kept under 40K during 2 hours and 30 minutes without LHe.
