Abstract
A superconducting cable line includes a heat insulation pipe for a fluid for transporting liquid hydrogen, a superconducting cable housed in the heat insulation pipe for a fluid, and heat exchange means for performing a heat exchange between liquid hydrogen and a refrigerant of the cable. The superconducting cable includes a cable core inside a heat insulation pipe for a cable and is housed in the heat insulation pipe for a fluid to form a low temperature environment around the cable and a double heat insulation structure including the heat insulation pipe. Therefore, since heat intrusion into the superconducting cable is reduced and the refrigerant is cooled with liquid hydrogen, the line can reduce energy for cooling the refrigerant.
Claims12
A superconducting cable line, comprising:
- a heat insulation pipe;
- liquid hydrogen in said heat insulation pipe;
- a superconducting cable housed in said heat insulation pipe;
- a refrigerant in said superconducting cable, the refrigerant having a temperature higher than that of said liquid hydrogen and cooling a superconducting portion of said superconducting cable;
- and
- a heat exchange means for cooling said liquid hydrogen and raising a temperature of said refrigerant in said cable cooled with said liquid hydrogen;
- and
- said heat insulation pipe and said superconducting cable being configured such that said liquid hydrogen flows outside said superconducting cable and said refrigerant flows inside of said superconducting cable.
