Arrangement with a superconductive electrical direct current cable system

摘要

An arrangement with a superconductive electrical direct current cable system is specified which includes at least one direct current transmission element (4) composed of two phase conductors which are insulated relative to each other, and a cryostat suitable for conducting a cooling agent, in which the direct current cable system is arranged. The cryostat is composed of at least one metal pipe which is surrounded by a circumferentially closed layer with thermally insulating properties. Each of the two phase conductors (5,6) is composed of several superconductive elements (9) which are combined into a unit. Between the two phase conductors (5,6) is mounted a separating layer (7) of insulating material, and the two phase conductors (5,6), including the separating layer (7) are surrounded by a sheath (8) of insulating material for forming a direct current transmission element (4).

1. Arrangement with a superconductive electrical direct current cable system comprising:
at least one direct current transmission element composed of only two phase conductors units which are insulated relative to each other, wherein each of the two phase conductors units is composed of several superconductive elements, a separating layer of insulating material is mounted between the two phase conductors units, within each of said direct current transmission element, the two phase conductors, including the separating layer, are surrounded by a single sheath of insulating material for forming said direct current transmission element, and a cryostat suitable for conducting a cooling agent, wherein the cryostat is composed of at least one metal pipe which is surrounded by a circumferentially closed layer with thermal insulating properties, and wherein said phase conductors units are directly cooled by the cooling agent conducted through said cryostat.
