A cooling fluid system for providing cryogenic cooling fluid to a high temperature Super-Conducting rotor comprising:
- a cryogen storage tank storing a liquid cryogenic cooling fluid;
- an inlet transfer line connecting the storage tank to the rotor and forming a passage for liquid cooling fluid to pass from the tank to the rotor,
- wherein said storage tank is elevated above the rotor and the liquid cooling fluid is gravity fed to the rotor.
A cooling fluid system coupled to a high temperature super-conducting rotor for a synchronous machine and a source of cryogenic cooling fluid comprising:
- a cryogenic storage tank and a supply of cryogenic cooling fluid stored in the tank, wherein the tank is elevated above the rotor;
- an inlet line providing a fluid passage for the cooling fluid between the tank an the rotor;
- a return line providing a fluid passage for the cooling fluid between the rotor and tank, and
- a cryorefrigerator cooling the fluid in the storage tank.
A method for cooling a super-conducting field winding coil in a rotor of a synchronous machine using an elevated cryogen storage device comprising the steps of:
- a. storing cryogenic cooling fluid in the tank, wherein the tank is elevated above the rotor;
- b. allowing the cooling fluid to flow under the force of gravity from the tank to the rotor;
- c. cooling the field winding coil with the cooling fluid, and
- d. returning the cooling fluid to the tank.
