<p><P>PROBLEM TO BE SOLVED: To provide a connection structure for a DC superconductive cable which can remove foreign matter carried together with a refrigerant. <P>SOLUTION: This connection structure is equipped with a superconductor 11 provided in a cable core 10 drawn out of a superconductive cable, a conductor lead-out part (a sleeve 12, a lead part 13, a joint part 14, and a bushing 15) on normal temperature side connected to the superconductor 11, and a terminal connection box 20 where these connection points are stored. The terminal connection box 20 is equipped with a refrigerant container 21 filled with a refrigerant and a vacuum container 22 arranged to cover the periphery of the refrigerant container 21. A supply path 23, which supplies a refrigerant into a box 21 and a discharge path 24, which discharges a refrigerant from the box 21, are connected to the refrigerant container 21, and the refrigerant is circulated by these supply path 23 and the discharge path 24. The supply path 23 is equipped with a filtering means 1, which removes foreign matter f carried together with the refrigerant. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
