    The invention relates to electrical, engineering and power engineering and can be used in the design and manufacture of magnets with superconducting windings, mainly for trains on a magnetic cushion.
    The purpose of the invention is to increase efficiency
    and reliability of superconducting magnet I
    FIG. 1 shows a superconductor -
    General magnet; figure 2 is the same option; in fig. 3 - the same
    The cross section of FIG. one; on
    Fig, 4 - the same, cross section
    in FIG. 2; in fig. 5 — execution of a superconducting magnet partition
    option.
    In a superconducting magnet, mainly for trains on a magnetic cushion containing frame 1, winding 2 of superconducting conductor, filled as a closed contour, placed in a curable material 3 and made in a cross section of a rectangular shape, frame 1 is worn as an annular box of a C-shaped cross section and provided with an internal partition 4 with a rectangular cross section, the edges of which, combined with the edges of the box, are made along the outer forming box and the cover 5 of an annular shape, the edges which are connected to the duct in the zone of its edges, the cavity between the partition and the annular casing forms a volume for recycling the refrigerant, mainly liquid helium, and in the cavity between the partition 4 and the lid 5 there is a winding 2 with cured material 3. the sides of the rectangular cross section winding 2 are adjacent to the partition 4, and the fourth to the cover 5 of the box. The partition box is made as a single structural element and forms a template for winding winding 2. The lid (Fig. 2) is equipped with means 6 for injecting curable material 3. The partition 4 (Fig. 5) is equipped with three additional plates 7 of electrically conductive material ,. placed on the inner walls of the partition wall, the plates being the same size as the sides of the rectangular winding 2. The additional plates are made of metal. In the method of manufacturing a superconducting magnet, mainly for trains on a magnetic cushion, comprising the steps of making the carcass, winding the winding conductors and impregnating with curing material by introducing the latter through the injection means, after winding the windings of the winding on the edge of the carcass, put a cover and a hermetic - primarily connected by welding the edge of the frame with the edges of the flare, then the joints are cooled to a temperature lower than the temperature causing the raster curing of curable material. After impregnation of the winding with a curable material, the injection means is closed.

    According to the embodiments of FIG. 2 and 4, a winding 2 of a superconducting conductor can be placed directly at the outer surface of the frame 1, with the volume for the circulation of the refrigerant located at the inner surface of the frame along its internal generatrix. According to the embodiment of FIG. 2, in the volume for circulation of the refrigerant, stiffening ribs can be made adjacent its partition to the partition wall 4. Here, in the volume for the circulation of the refrigerant along the path of the refrigerant, there are plates with openings for the passage of the refrigerant. In an embodiment. In FIG. 5 additional plates 7 serve to better wind the winding wire at the corners of a rectangular cross section. In addition, the conductivity of the winding structure is improved due to the use of metal plates with good conductivity. I.
    A method of manufacturing a superconducting magnet involves impregnating the winding with a curing material after the welding operation of a framework with a lid at a temperature lower than the temperature causing cracking of the curing material. As a curing material, an epoxy resin can be used, which is injected through the means 6 to inject the curable material. Air from a volume filled with a winding exits through a similar means (not shown). After impregnation, the winding with the curing material injecting agent is closed.
