Embodiment Construction

[0014] exist figure 1 and 2 shows a superconducting cable according to the invention with only two conductors in each case. It is of course also possible to have a larger number of wires which are integer multiples of 2.

[0015] in press figure 1 In the embodiment of , a cryostat KR is shown, which consists of two metal tubes 1 and 2 arranged coaxially with each other, with a vacuum insulation layer 3 between the metal tubes 1 and 2 . Of course, the cryostat KR can also have other structures if it is ensured that the space enclosed by the cryostat KR is effectively protected against the ingress of heat from the outside. Arranged in the cryostat KR is a cable-shaped carrier 4 made of insulating material, which leaves a free space FR for the passage of coolant relative to the inner tube 2 of the cryostat KR. The insulating material of the carrier 4 must be stable at the low temperatures of the coolant used in the operating conditions. According to the design described abov...

Abstract

The present invention relates to a direct current supraconductor cable which is provided with at least two conductors (7,8) which are insulated from each other. The direct current cable is provided in a low temperature thermostat (KR) which is suitable for guiding coolant. The low temperature thermostat is composed of at least one metal pipe. The metal pipe is surrounded by a closed surrounding layer with a thermal insulation performance. The low temperature thermostat is provided with a string-shaped carrier (4) which is composed of an insulation material. The carrier (4) is provided with at least two outwardly opening grooves (5,6) which are oppositely placed along a radial direction. The grooves (5,6) are internally provided with one of the conductors (7,8) respectively. Each conductor (7,8) is composed of a plurality of supraconductor components.

Description

technical field [0001] The invention relates to a superconducting direct current cable having at least two conductors insulated from each other, which for use can be arranged in a cryostat suitable for conducting a coolant, the cryostat consisting of At least one metal tube is formed, which is surrounded by a surrounding, closed layer with thermal insulation properties. Background technique [0002] Such a cable is known from WO 2008 / 148390 A1. [0003] Superconducting cables in today's technology have electrical conductors made of a composite material containing a ceramic material that enters a superconducting state at sufficiently low temperatures. With sufficient cooling, the direct current resistance of a correspondingly constructed wire is zero, as long as a specified current intensity is not exceeded. Suitable ceramic materials are for example BSCCO (bismuth-strontium-calcium-copper-oxide) as a first generation material or ReBCO (rare earth-barium-copper-oxide), espe...
