DEVICE WITH SUPERCONDUCTIVE CABLE Russian patent published in 2013 - IPC H01B12/16 

FIELD: electrical engineering.

SUBSTANCE: proposed is a device for electrically conductive connection of a superconductive electric cable (1) with a normal conductivity electric cable at room temperature, the device having a feedthrough insulator (D) with an electric conductor (5) surrounded by thermal insulation (6). The superconductive cable conductor (1) is coupled with the end of the feedthrough insulator (D) conductor (5), the normally conductive cable connected on the other side of the latter. An electrode (4) is at a certain end of the superconductive cable (1) for connection to the feedthrough insulator (D) conductor (5), the electrode serving for electric control by way of magnetic field variation. At least within the electrode (4) area a cryostat is in place that is designed as a circumferentially closed casing of an electrically insulating material with non-vacuum thermal insulation. While the device is in an operational condition, the end of the feedthrough insulator (D) casing lie under the HV potential while the other end of the casing is connected to the ground potential.

EFFECT: simplification of device design.
