Description
Technical Field
The invention belongs to the technical field of high-temperature superconduction, and particularly relates to a common vertical plane transposition high-temperature superconducting cable and a winding transposition method.
Background
The high-temperature superconducting strip has an operating temperature and a critical magnetic field which are far higher than those of low-temperature superconductors, and provides a better choice for building a high-magnetic-field magnet, such as a fusion reactor magnet, an accelerator magnet, a detector magnet and the like. The critical current of the high-temperature super-strip has obvious anisotropy, and in order to fully utilize the critical current of the strip, the normal direction of the strip surface of the strip needs to be vertical to the direction of a magnetic field; for an unsteady state operation environment, the high-temperature superconducting cable needs to be symmetrically transposed, so that the alternating current loss of the cable is reduced. When the high-temperature superconducting cable with a common structure is transposed, the surface normal of the strip changes along with the length direction of the strip constantly, and generally, the normal of all the strips is difficult to be always vertical to the direction of a magnetic field, so that the current carrying capacity of all the strips is difficult to be fully utilized, and the economy is poor.
With the promotion of critical current of high-temperature superconducting tapes and the development of cutting technology, the circular conductor with smaller diameter is manufactured by using the high-temperature superconducting narrow band, the bending property of the circular conductor is close to that of a copper wire with the same diameter, and the advantage can be fully utilized to wind a large-current cable with the characteristic of common vertical plane transposition. Patent CN 110246625A, CN 110706860a is a typical rutherford cable, where the high temperature superconducting stacked rectangular and circular strands are spatially transposed at a certain angle, the tape surface of the strand rotates 360 ° in one period, when the cable is used for winding magnets, all the tapes will have a portion where the normal of the tape surface is parallel to the magnetic field, resulting in that only the minimum current carrying capacity of the tape can be utilized. Therefore, it is necessary to optimize the structure and process of the high temperature superconducting cable and fully utilize the current carrying capacity of the tape.

The conductor framework is cylindrical or cylindrical with an oblong cross section.
The cooling medium is liquid nitrogen, liquid helium or low-temperature helium.

And a plurality of layers of folded yarns are wound outside the conductor framework, and the single layers and the even layers of folded yarns are alternately arranged clockwise and anticlockwise respectively.
The folded yarn is divided into 2-4 layers and is wound outside the conductor framework.
All the strands are spirally wound on the surface of the conductor framework at a certain angle, and the angle is 5-30 degrees.
The folded yarn metal material is made by packaging, and is made of tin, lead, tin-lead alloy, gold, aluminum, copper or alloy of 2 components.

Detailed Description
The invention is further illustrated by the accompanying drawings and the detailed description.
The common vertical plane of the transposition high-temperature superconducting cable designed by the invention means that the inner high-temperature superconducting strip surface has the same or similar vertical plane under the straight state of the cable; transposition means that there is an interpositioning between the strands of the cable, so that the strands have a reproducibility in spatial position. The cable is suitable for magnets with strong magnetic fields and power cable equipment, such as fusion reactor high-temperature superconducting magnets, accelerator magnets, detector magnets, ore dressing magnets, motors, transformers and the like.
Example 1
As shown in fig. 1 and 2, the co-vertical transposing high temperature superconducting cable includes a conductor former 1 and a metal sheath 5.
The conductor framework 1 is tightly wound with the strands 4 and is completely covered by the outer metal sheath 5.
The folded yarn 4 is tightly wound on the surface of the conductor framework 1 at a certain angle.
The strands 4 are composed of a hollow cylindrical cladding material and an inner stacked conductor 2.
The stacked conductor 2 is a multilayer structure formed by stacking a plurality of strip conductors (tapes), and has a square-shaped cross section. The plane of each layer is the tape side 3. All the strip conductors (ribbons) are always perpendicular to the same plane, i.e. perpendicular to the ribbon plane 3. The belt surfaces 3 have the same vertical surfaces (coplanar surfaces) in the belt material longitudinal direction.
As shown in fig. 3d, all the strands 4 are spirally wound at a certain angle around the outer part of the conductor framework 1, while the tape surfaces 3 of the tapes of all the strands 4 are all parallel, i.e. tightly wound at a certain angle around the surface of the conductor framework 1 under the condition that all the tape surfaces at the inner part are always perpendicular to the vertical surface of the tape surface 3;
it is essential that all the strip faces 3 are parallel in cross section, but the strip faces 3 are curved when wound in the strip length direction, and parallel faces cannot be defined, but the curved faces have a common vertical plane, i.e., the YZ plane in fig. 3a, and are therefore defined as co-vertical plane conductors.
Fig. 3a, 3b and 3c illustrate the coplanar definition of the plane 3 of the strip, with fig. 3a being an oblique view of a single strip being wound with the plane of the strip always perpendicular to the YZ plane, the projection of the strip onto the YZ plane being a thin line (shown in fig. 3 b) and the projection of the strip onto the XZ plane being the plane of the strip (shown in fig. 3 c).
The metal sheath 5 is of a hollow structure, completely covers the strand 4 and the framework 1 inside, and simultaneously plays a role in supporting and protecting the strand 4; a cooling medium channel is arranged in the inner gap of the metal sheath 5, and the cooling medium is used for keeping the high-temperature superconducting conductor 1 at a constant temperature; the cooling medium is liquid nitrogen, liquid helium or low-temperature helium (the temperature is 4.2-77K).
In this embodiment, the strands 4 are formed of a hollow cylindrical shape, and the conductive skeleton 1 is formed of a cylindrical shape. The metal sheath 5 is hollow cylindrical and has a double-layer structure, and a cooling medium channel is arranged in the middle gap.
Example 2
Another embodiment of the present invention is shown in fig. 4 and 5. The cross section of the conductor framework 1 is oblong, namely the main body is rectangular, two ends of the conductor framework are semi-circles, the folded yarn 4 is tightly wound on the surface of the conductor framework 1 at the same angle, and the cross section of one winding circle is shown in the figure. The outer metal sheath 5 compresses the strands 4 and is also hollow with a rectangular outer surface.
The strip faces 3 of the strips of all strands 4 are all parallel and parallel to the axial direction of the conductor skeleton 1.
As shown in fig. 6, the strand 4 is wound using a homeotropic winding transposition method: the arc center line of the conductor framework 1 is taken as the winding central axis of the strand 4, the strip surfaces 3 in all the strand 4 are parallel, and in order to ensure that all the strip surfaces are always vertical to the vertical surface of the initial strip surface 3 during winding, the strand 4 rotates around the Xc axis (central axis) of the framework 1 by an angle theta (the included angle between the winding axis and the winding direction), and simultaneously reversely rotates around the fixed axis Xs of the wire coil 6 by an angle theta.
After winding, the strip planes 3 of all the strands 4 are parallel, namely always perpendicular to the vertical plane of the initial plane, and a certain position of the side surface of each strand 4 is periodically contacted and separated with the conductor framework 1 and is periodically in a compressed or stretched state.
Taking a rectangular common vertical plane transposition high-temperature superconducting cable containing 20 strands as an example, circular strands of the cable are formed by stacking and packaging high-temperature superconducting tapes with the width of 3mm and the thickness of 0.1mm, the tapes have typical critical current values of 130A and 900A of a vertical field and a horizontal field under a background magnetic field of 4.2K and 20T, when the common vertical plane of the common vertical plane transposition high-temperature superconducting cable is perpendicular to an external magnetic field, the critical current of the cable reaches 540kA, and the common transposition cable can only utilize the lowest vertical field current, namely 78 kA. In the actual process of winding the cable, all the strips are difficult to ensure to be completely vertical to the same plane, a certain angle deviation is allowed, the angle between the strip surface of the high-temperature superconducting strip and the common vertical surface is controlled within 80-90 degrees, and the critical current of the common vertical surface transposition high-temperature superconducting cable can be still improved by more than one time compared with that of a common transposition cable.
The strand 4 is made of metal material, typically tin, lead, tin-lead alloy, gold, aluminum, copper or alloy of 2 components thereof.
The metal sheath 5 is used for supporting and protecting the high-temperature superconducting strand from being damaged by huge electromagnetic force or mechanical stress, according to the structure of the strand after winding, the inner contour of the section of the metal sheath 5 is circular or track-shaped, the outer contour of the section of the metal sheath is circular, track-shaped or chamfer-rectangular, and the material of the metal sheath can be stainless steel, copper, aluminum, copper alloy or aluminum alloy.
The stacked conductor 2 is stacked in a rectangular or nearly rectangular cross section from a plurality of strips of one or more gauges. The specification of the strip is 1-5mm in width and 0.05-0.2mm in thickness.
The multilayer strand 4 can be wound around the conductor framework 1, when the multilayer strand is wound, the single layer and the even layer of the strand 4 are wound alternately clockwise and anticlockwise respectively, the winding angle is determined according to the framework size, the strand diameter and the winding intercept of the high-temperature superconducting cable with the transposition of the common vertical plane, and after the winding is finished, the planes of the high-temperature superconducting tapes in the single-layer or multilayer wound high-temperature superconducting strands are kept parallel in any section of the cable.
