摘要： A vapor cooled current lead for a superconducting device located in a cryostat includes a normal conductor section extending from ambient conditions inward to an intermediate point, and a composite lead having a ceramic high temperature superconductor core with a metallic sheath extending between the normal conductor section and the superconducting device, preferably in a helical path to reduce heat leak by conduction. The metallic sheath is stripped away at spaced intervals, preferably adjacent the low temperature end of the composite lead, and the gaps are filled with a filler which provides mechanical strength for the core and reduces thermal conduction. A flow of cryogen vapor directed by a tubular housing maintains the high temperature superconducting material below its critical temperature, and cools the normal conductors.

摘要： A power lead for a cryostat has high temperature superconducting (HTSC) conductors extending inward toward a pool of liquid cryogen in the cryostat in series with normal conductors extending from the HTSC conductors to outside the cryostat. Tubular shrouds vented to atmosphere direct a flow of cryogen vapor along the HTSC conductors to maintain them superconducting, and along the normal conductors to remove Joule heat and heat leakage along the normal conductors. In one embodiment, a pool of liquid nitrogen maintained within a tubular inner shroud is the principal coolant for the normal conductors. Helium vapor is circulated over the HTSC conductors and is then directed by an outer tubular shroud around the inner tubular shroud to provide additional cooling for the normal conductors. Flexible connectors at one end of each of the HTSC conductors accommodate for individual thermal contractions of these conductors.

摘要： A multiple circuit hybrid cryostat power lead has a plurality of laterally spaced, electrically isolated lead elements inside a tubular enclosure. Each lead element has an inner section with a high temperature superconducting (HTS) conductor inward of a divider in the tubular enclosure, and an outer normal conductor section outward of the divider. The outer sections of the lead elements have a pair of copper conductors spirally wound in an annular chamber between an electrically insulating central support and an electrically insulating sleeve to form helical flow passages. Cryogen vapor flows outward in the tubular enclosure inward of the divider over the HTS conductors, through a slotted heat exchanger electrically connecting the HTS and copper conductors at the divider, and through the helical flow passages to vents at outer terminals. Flow distribution in the helical passages is regulated either by a flow baffle diverting flow at an intermediate point in the helical flow passages through apertures in the sleeves into the tubular enclosure for mixing and reintroduction of the mixed cryogen vapor back into the helical passages through additional apertures in the sleeve outward of the flow baffle, or by individual thermally responsive valves in the flow passages.

摘要： A superconducting magnetic energy (SMES) system having an axially sectioned multilayered solenoid coil immersed in a liquid helium bath contained in annular helium vessel includes as an interface between each section of the inner and outer layers of the coil and the helium vessel a finger plate assembly comprising a plurality of electrically nonconductive finger plates clamped at one end with spacers between adjacent finger plates to hanger plates welded to the helium vessel walls. The other ends of the finger plates are interleafed with the turns of the coil and clamped together with the coil turns by clamping assemblies which clamp the turns in adjacent layers of the coil. Loading bars between the layers transmit the radial loads generated by the magnetic and thermal forces acting on the coil to the finger plates. The radial loads pass through the finger plates to the helium vessel side walls and then through radial struts outside the helium vessel to the walls of a trench in which the SMES system is installed. Axial loads on the coil produced by the Lorentz force and differential thermal expansion and contraction of the coil relative to the helium vessel are absorbed in bending of the finger plates.

摘要： A high temperature solid oxide fuel cell generator produces electrical power from oxidation of hydrocarbon fuel gases such as natural gas, or conditioned fuel gases, such as carbon monoxide or hydrogen, with oxidant gases, such as air or oxygen. This electrochemical reaction occurs in a plurality of electrically connected solid oxide fuel cells bundled and arrayed in a unitary modular fuel cell stack disposed in a compartment in the generator container. The use of a unitary modular fuel cell stack in a generator is similar in concept to that of a removable battery. The fuel cell stack is provided in a pre-assembled self-supporting configuration where the fuel cells are mounted to a common structural base having surrounding side walls defining a chamber. Associated generator equipment may also be mounted to the fuel cell stack configuration to be integral therewith, such as a fuel and oxidant supply and distribution systems, fuel reformation systems, fuel cell support systems, combustion, exhaust and spent fuel recirculation systems, and the like. The pre-assembled self-supporting fuel cell stack arrangement allows for easier assembly, installation, maintenance, better structural support and longer life of the fuel cells contained in the fuel cell stack.
