COOLING MEDIUM SUPPLYING/DISCHARGING MECHANISM FOR SUPERCONDUCTING ROTARY ELECTRIC MACHINE, AND SUPERCONDUCTING ROTARY ELECTRIC MACHINE

Japanese Patent JP2023112466

A

To provide a simple structure so as to inhibit a temperature increase of a cooling medium, and inhibit a seal part from being excessively cooled.SOLUTION: A cooling medium supplying/discharging mechanism for a superconducting rotary electric machine according to an embodiment includes: a casing including a first fixed pipe that is used to supply a cooling medium, and a second fixed pipe that is used to discharge the cooling medium and that is disposed so as to surround at least a portion of the first fixed pipe; a rotor including a first rotary pipe that feeds the cooling medium supplied from the first fixed pipe to a certain space in a rotor coil, and a second rotary pipe that is disposed so as to surround at least a portion of the first rotary pipe and that feeds the cooling medium having passed through the rotor coil, to the second fixed pipe; and a seal part that prevents the cooling medium from leaking from an area between the second rotary pipe and an end of the second fixed pipe. The second fixed pipe is disposed so as to surround a portion of the second rotary pipe, and a cooling medium residence space where the cooling medium stays is formed between the surrounded portion of the second rotary pipe and the portion of the second fixed pipe.SELECTED DRAWING: Figure 1
