    The invention relates to electrical engineering, mainly to cable technology, namely, to structures of stranded superconducting wires / used in alternating current cryogenic machines ...
    The closest to the proposed technical entity is a flat stranded superconducting wire containing superconducting wires arranged at an angle to the longitudinal OCIJ around the flat separator SI.
    In this wire, the transition of the core from the superconducting state to the normal state can be detected by detecting the voltage of resistive origin, which causes such a transition at the ends of the wire. But this voltage can be much less than the voltage induced on the conductor length by alternating magnetic fields.
    The induced voltage can be eliminated by using one of the metal conductors of the superconducting wire as a detection line.
    To reveal the resistive voltage in this case, it suffices to subtract the voltage induced in this line from the total voltage, resistive and induced, appearing in the main conductor.
    The disadvantage of the wire is that if the detection line is located instead of one of the superconducting conductors: 1B, there is a heterogeneity of the superconducting layers, which degrades both the electrical and mechanical characteristics of the wire.
    The purpose of the invention is to improve the electrical and mechanical characteristics
    This goal is achieved by the fact that in a flat multi-core superconductor, in that wire containing a superconductor sh. Iw lived-, located at an angle to the longitudinal axis around a flat separator made of insulating material, and a detection line running along the entire length. wires, the separator is made of several tapes, the detecting line is in the form of a flat metal conductor located between the separator tapes to form a core, and the length of the conductor path in the wire exceeds the length of the latter not m Less than 10%.
    The trajectory of the conductor may have a wave-like shape, while the edges of the separator tapes have alternating notches located opposite the hollows in the conductor.
    The core wire can also be wrapped around the insulating tape.
    Fig, 1 shows a wire with a wave-like path of a conductor; 5 in FIG. 2 is a variant of a wire where the core is wrapped around an insulating tape,
    The superconducting cores 1 (fig. 1) form two layers adjoining each other.
    0 to each other’s edges, each vein alternately moving from the upper layer 2 to the lower 3, each time crossing the entire width of the layer and thus forming a crossing of a known type.
    Both layers are separated by a separator consisting of a tubular insulating sheath 4 with a width of 7 and a thickness of 0.4 MIV1 in a compressed state. Braid
    Q may consist, for example, of threads of an aromatic polyamide. In the braid along its entire internal length there are two polyamide layers 5, which are an excellent electrical KIM insulator. The thickness of each layer is, for example, 25 microns.
    Between these two layers is a wavy ribbon of copper 0.05-1.0 MtA thick and about 1 mm wide.
    This wavy tape is at least partially a metal core, which ensures the action of the detecting line. The waviness increases the flexibility of this core in the HOA plane. Wavy step
    5 may be 5 mm with an amplitude of, for example, 1 mm. To further increase the flexibility of the core, the lateral edges of the insulating tapes 5 contain cutouts against the concavities of the undulating tape b,
    In the wire shown in FIG. 2, the superconducting wires 7 are arranged as wires 1 in FIG. 1, But a separator in the form of a cocTotiT tape from a core, made in the form of a metallic conductor 8, provided with an insulating coating in the form of layers 9, which is wrapped around an insulating
    0 tapes 10. First, metal tape 8 is placed between two insulating tapes (polyamide), with the above tapes being wider-last and glued to one another with their edges on both sides of tape 8 ,. completely around her first insulating jacket 3, thus obtained more
    a wide tape 9 is wound on a flat helix by tight connecting turns on the insulating tape 10, then placed in a second insulating sheath 11 consisting of a braid,
    similar braid 4.
    The use of the invention allows by placing the detection line in the separator without significantly increasing its thickness and flexibility.
    to significantly improve the mechanical and electrical characteristics of the superconducting wire,.
