Abstract
The present invention is directed to a cylindrically shaped superconductor component particularly useful as resistive current limiter composed of a cylindrical superconductor body, in particular of high temperature superconductor material, provided vertically to its longitudinal axis with a number of azimuthal slots 3, incised in parallel and alternating, and one longitudinal slot 2 running parallel to the longitudinal axis over almost the whole length of the cylindrical superconductor body.
Claims11
A cylindrical superconductor component comprising:
- a cylindrical superconductor body, wherein the cylindrical superconductor body is provided with a longitudinal slot extending parallel to the longitudinal axis of the superconductor body at a distance from the lower end to a distance of the upper end of the cylindrical superconductor body, leaving a non-cut section between the lower end and the upper end, respectively, of the cylindrical superconductor body, and the starting point and the end point, respectively, of the longitudinal slot, and a number of azimuthal slots incised vertically to the longitudinal slot into the cylindrical superconductor body,
- wherein each individual azimuthal slot is cut into the cylindrical superconductor body starting from the longitudinal slot and extending along the perimeter of the cylindrical superconductor body until an end point with a distance from the longitudinal slot, said distance between the longitudinal slot at the start of the respective azimuthal slot and the end point defining a non-cut section on the perimeter of the cylindrical superconductor body,
- wherein the azimuthal slots are cut into the perimeter of the cylindrical superconductor body in parallel and
- wherein each individual azimuthal slot starts from said longitudinal slot in a sense along the perimeter of the cylindrical body opposite to the sense of the azimuthal slots immediately neighbouring the individual slot along the longitudinal slot.
Method for producing a cylindrical superconductor component, said method comprising the steps of
- providing a cylindrical superconductor body with a longitudinal slot and vertically to the longitudinal slot with a number of azimuthal slots,
- extending the longitudinal slot a distance from the lower end to a distance of the upper end of the cylindrical superconductor body leaving a non-cut section between the lower end and the upper end, respectively, of the superconductor body and the starting point and end point, respectively, of the longitudinal and
- incising the number of azimuthal slots 3 in parallel and alternating and wherein each azimuthal slot is cut into the cylindrical superconductor body starting from the longitudinal slot and extending along the perimeter of the cylindrical superconductor body until an end point with a distance from the longitudinal slot, the distance between the longitudinal slot at the starting point of the respective azimuthal slot and the end point defining a non-cut section on the perimeter of the cylindrical superconductor body wherein each individual slot starts from said longitudinal slot in a sense along the perimeter of the cylindrical body opposite to the sense of the azimuthal slots immediately neighboring the individual slot along the longitudinal slot.
