PROBLEM TO BE SOLVED: To provide a superconductive power transmission system capable of stably circulating a coolant inside of a superconducting cable without using a circulation pump, and to provide a structure with the system.SOLUTION: A superconductive power transmission system comprises: a disposed double pipe with an inner pipe and an outer pipe forming a height difference therebetween; an electroconductive member which extends in an axial direction of the double pipe within an outside space of an inner pipe and is formed from a superconducting material; a first lead member and a second lead member which are electrically connected with the electroconductive member; a coolant formed of nitrogen filling the double pipe; a slush nitrogen generation system which is capable of generating solid-state nitrogen particles by cooling the coolant in an upper communicating space of the double pipe and configured to carry out sedimentation of the solid-state nitrogen particles within the inner pipe; sensors each for measuring a controlled variable corresponding to a solid phase rate of the coolant in a lower communicating space; and a control device for controlling a cooling capability of the slush nitrogen generation system on the basis of the controlled variable measured via at least one sensor. |
