Abstract: A coolant replenishing system for cooling the superconducting field winding of a machine, illustratively a turbo-generator. The machine is provided with a rotating antechamber in which is disposed a coolant in liquid and gaseous phases. Liquid coolant is delivered to the antechamber from a supply tank by a coolant supply line. The discharge opening of the coolant supply line in the antechamber is oriented away from the axis of rotation of the machine, and disposed at a predetermined radius with respect to the axis so that the input pressure of the coolant at the opening of the coolant feed line is in equilibrium with the pressure of the liquid coolant in the rotating antechamber.

The rotor comprises a superconducting exciter winding part which is to be cooled by a cryogenic coolant, and to which winding part the coolant is introduced via at least one appropriate coolant supply line. The chambers of the rotor winding part to be evacuated are directly connected to the cryosorption pump in the co-rotating transfer part. Furthermore, the cryosorption pump is thermally connected within the co-rotating transfer part with the at least one coolant supply line.

Abstract: An arrangement for cooling the field winding of an electric machine to be deep cooled is provided with a rotating mixing chamber containing vaporous and liquid coolant and with a centrifugal pump between areas of different temperatures to pump gaseous coolant out of the mixing chamber. The maximum flow cross section of the colder line part of the centrifugal pump is at the most half the size of the maximum flow cross section of the warmer line parts and/or at least the end piece of the colder line part is thermally coupled to colder parts of the rotor to prevent pump instabilities caused by coolant convection.

Abstract: A cooling arrangement for a superconducting field winding of an electric machine, especially a turbo-generator, has a coolant space which contains a cryogenic coolant fed into it via a feed line, for cooling the field winding, and a coolant supply chamber which contains liquid coolant for cooling a damper shield. So that no separate feed and discharge lines are required for cooling the damper shield independently of the cooling of the field winding, the coolant supply chamber is connected directly to the coolant feed line via a radial connecting line, and the flow cross sections of the connecting line and of the section of the coolant feed line between the connecting head and the connecting point of the connecting line are made large.

Abstract: A cooling device for a superconducting field winding of an electric machine, especially a turbo-generator, contains an exhaust gas line connected to a coolant space for cooling an end piece at the end face of a torque transmitting rotor body part as well as a coolant line extending along a damper shield arranged around the field winding.

Abstract: The cooling arrangement of the superconducting field winding of a turbo-generator contains a coolant chamber, in which a vaporous and a liquid phase of a coolant are contained, and to the vapor space of which a coolant discharge line with a high flow resistance is connected. To prevent excessive over-pressure in the coolant chamber in the event of a quench, a buffer tank is also connected to the vapor space via a connecting path having a relatively low flow resistance.
