Termination cryostat for an HTS power cable.

Author(s) : KIM D. L., KIM S. H., CHO S., et al.

Summary

The cryogenic system of the HTS cable is composed of an HTS cable cryostat, termination and refrigeration system. The termination of the HTS cable is a connecting part between copper electrical cable at room temperature and HTS cable at liquid nitrogen temperature. In order to design the termination cryostat, it is required that the conduction heat leak and Joule heating on the current lead be reduced, the cryostat be insulated electrically and good vacuum insulation be maintained during long term operation. The AC has been considered as an important parameter for the design of current leads for the HTS cable termination. Heat load calculations on the copper AC current lead have been performed by analytical and numerical methods and a feasibility study for the other candidate materials has also been executed. Since the resistance of the AC current lead has been affected by the skin effect, higher heat loads were generated in AC current lead compared to the DC current lead. The brass current lead generates higher heat load than the copper current lead in both AC and DC current leads.
