    摘要: A winding support body (6, 10) for transformers/reactors with a winding of a tape-formed superconductor (8), wherein the support body consists of a substantially straight, circular-cylindrical tubular body which, on the side where the winding is to be placed and out towards the two ends, is provided with a helical slot with a plane surface with a width equal to the width of the tape. In this way, each turn of the slot around the support body forms a surface which practically constitutes the envelope surface of a straight frustum of a cone. The angle (v) between a generatrix (9) of the envelope surface and the axial center line of the support body increases for each turn out towards the ends of the support body in such a way that the envelope surface at all points coincides with the direction of the magnetic field (FIG. 4 ).

    摘要: In order to make it possible to produce superconducting coils with small overall height, they are made from a plurality of coil subunits, optionally with a plurality of layers for each coil subunit, in particular in the case of the low-voltage coil of a transformer. The coil subunits contain as electrical conductor a high-temperature superconductor, around which a fibrous glass is spun and which is embedded in a glass-fiber reinforced epoxy resin or in a plastic. The coil subunits are placed around a transformer core in a cryostat.

    摘要: A cooling device for cooling of current leads (6, 7) in the bushings of a cryotank (1), wherein the current leads in the gas-filled part of the cryotank are designed as plate-formed sub-leads (12) surrounded by a casing (8) of insulating material with an inner open part of rectangular shape. Between all the sub-leads inside the cryotank there are arranged a number of rows of inclined transverse ribs (13a, 13b, . . . 13n, 14a, 14b . . . 14n) of insulating material. On the inner walls of the casing, facing the plate edges of the sub-leads, and at the ends of the transverse ribs, shelves (15, 16) are fixed whereby spiral cooling coils are formed around the current leads from the lower edge of the casing.
