摘要：
Termination cryostat for 22.9 kV, 1.26 kA-class high temperature superconducting (HTS) power cable has been designed. The cryostat consists of vacuum vessel, liquid nitrogen vessel, current lead, shield current lead and HTS power cable. The current lead and the HTS power cable are connected in the liquid nitrogen vessel. It is cooled by forced-circulation subcooled liquid nitrogen at temperatures of 70similar to80 K and pressures of 0.3similar to1.0 MPa. The optimum position and diameter of inlet and outlet for the liquid nitrogen is determined by numerical analysis. Temperature distributions in the liquid nitrogen vessel were investigated for seeking an effective cooling condition based on the flow stream profiles. The cryostat is designed to endure the mechanical stress induced by thermal shrinkage.
