Cryogenic cooling system for rotor having a high temperature super-conducting field winding

摘要

A cooling fluid system is disclosed 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 at a rate determined by a valve in the inlet transfer line.
