Embodiment Construction

[0015] The strands of a material with good electrical conductivity can be made of copper or aluminum or alloys of these materials. As a representative of all possible embodiments, they are also referred to below as "copper wire harnesses".

[0016] The superconducting cables used in the device according to the invention are advantageously designed as cables with a cold dielectric. It will be referred to simply as "cable" below. The cryostat surrounding the cable has at least one insulated metal tube. In the illustrated embodiment, it consists of two metal tubes arranged concentrically with each other, with a thermal insulation layer placed between them. The tubes can be corrugated transversely to their longitudinal direction. It is also possible to place more than two cables inside the cryostat.

[0017] figure 1 The cables shown are designed as single-phase cables with cold dielectrics. It has a cable core 1 in which is accommodated an inner conductor made of supercondu...

Abstract

The invention relates to a device having at least one superconducting cable (1) housed in a cryostat for conducting a coolant, the cryostat having at least one thermally insulated metal tube. Outside the cryostat is placed a material with good electrical conductivity consisting of at least two strands (6, 7) which are wound around the cryostat (KR) in two layers with opposite twist directions superimposed on each other material layer. The strands (6, 7) are firmly and immovably connected to the cryostat (KR) at several fixing points (8) spaced apart in the axial direction.

Description

technical field [0001] The invention relates to a device having at least one superconducting cable housed in a cryostat for conducting a coolant, the cryostat having at least one heat-insulated metal tube, wherein outside the cryostat A material with good electrical conductivity (EP2071589A1) is provided which rests against the cryostat. Background technique [0002] A superconducting cable has at least one electrical conductor made of a material that transforms into a superconducting state at a sufficiently low temperature. At this time, the DC resistance of this conductor is equal to zero. Suitable materials are, for example, YBCO (yttrium-barium-copper oxide) or BiSCCO (bismuth-strontium-calcium-copper oxide). The sufficiently low temperature is, for example, between 4K and 110K for this material to reach the superconducting state. Suitable coolants are, for example, nitrogen, helium, neon and hydrogen in the gaseous or liquid state or mixtures of these substances. So...
