摘要： Cryostability is achieved by a superconductive rotor of a dynamoelectric machine constructed in accordance with the invention. The superconductive rotor comprises: a rotor shaft; a support rim; a plurality of slot teeth formed at the outer periphery of said rim, said teeth located between and defining a plurality of rotor slots; and a plurality of slot assemblies, one within each rotor slot. Each slot assembly comprises: a plurality of stacks of superconductors, each superconductor within a stack having insulation on only two of its sides and being disposed one on top of another in generally radial direction relative to the rotor shaft; a plurality of insulative separators, one between each pair of stacks; a top insulative strip and a bottom insulative strip, respectively radially above and below said conductor stacks; and a side panel on either side of the slot assembly and next to a slot tooth. Cooling channels are disposed on the surfaces of the separators, the side panels and the top and bottom strips so as to establish at least one coolant path along which coolant may be circulated to, within and from the slot assembly by natural convection.

摘要： The end turn region of a superconducting rotor is provided with end region support blocks that together provide channels for coil location. Within the support block channels there are intermittent supports in the form of insulating spacers extending radially both to the front and to the rear of the coil and also bottom spacers, with sheets of side insulation between the front and rear spacers and the adjacent support blocks. The intermittent supports provide access of coolant to the superconductor. They may also be formed in a manner to tilt the end region toward the pole piece for better mechanical support. A top insulating spacer is provided with cooling channels and is utilized with banding to provide secure compressive support for the end windings. Apertures in the support blocks and grooves in the spacers provide collant circulation.

摘要： The present invention provides a straightforward sensor and method for quench detection in a superconducting coil, magnet or inductor. The superconducting sensor of the present invention consists of a probe having a twisted loop of superconducting wire in a protective sheath which is co-wound with the superconducting coil, and a readout device. A very small amount of energy is applied to the superconducting loop of wire in the probe by the readout device and its resistance is monitored by readout device. When joule heating occurs in the superconducting coil as a result of a portion becoming normal, the heat is transferred to a corresponding portion of the probe causing a portion of the superconducting wires therein to become normal. This causes the resistance in the superconducting wires to change and this change is detected or measured by the readout device which is magnetically coupled to the wires of the probe.

摘要： A superconducting rotor cooling system for an electrical generator includes a free vortex type pump which is located within and forms an integral part of the rotor assembly. The free vortex pump takes advantage of the centrifugal force of rotation of the cooling fluid to help the rotor winding compartment to remain in a superfluid helium state. Improved cooling results from combined natural convection, as occurs in a conventional rotor, and the superfluid heat transport which occurs at the velocity of sound.

摘要： A rotor for a superconducting generator with improved thermal transient response is disclosed and claimed. In particular, a cylindrical radiation shield disposed about said rotor is given the twin-functions of protecting the rotor from radiant heat from the ambiance, as well as warming the coolant during abnormal operating conditions to ensure minimal damage from thermal transients. Thermohydraulic stabilization of the coolant flow through axial passages in the shield is achieved by the use of risers located within the flow path at the discharge end of the shield.

摘要： A superconducting generator or alternator in which the electrical winding is disposed within a fluid impervious outer shell. Liquid coolant is introduced into the interior of the shell via a liquid coolant supply pipe that terminates in an axially extending liquid coolant intake trough. The trough separates the incoming coolant from an annular coolant bath that submerges the electrical winding of the generator during superconducting operation. Heat conducting tubes extend radially outward from the bottom of the trough and permit a flow of liquid coolant therethrough to adjacent the outer shell. Sensible heat of compression (resulting from the rotation of the generator) produced in the coolant stream in the tube is at least partially withdrawn from the stream by the tubes and transferred to the inner surface of the bath so that the coolant is discharged from the tubes at a lesser temperature than would otherwise be the case. The discharged coolant is circulated past the electrical winding towards the inner surface of the annular coolant bath where it evaporates. The center of the generator is maintained at a vacuum and coolant vapor is withdrawn and circulated through a conventional refrigeration system for return in liquid form to a liquid coolant supply pipe which in turn flows the coolant back into the trough. A liquid coolant accumulator can be employed in the liquid coolant supply so that the coolant is maintained at a constant pressure. Variations in the coolant demand are self-regulated by corresponding variations in the depth of the coolant intake pool in the trough.
