Description

Sheath type high-strength superconducting cable twisting device and method for twisting cable

technical field

The invention belongs to the technical field of cable processing, and in particular relates to a sheath type high-strength superconducting cable twisting device and a method for twisting the cable.

Background technique

High current and strong magnetic field are the significant characteristics of superconducting magnets for high-field applications, which requires the components of superconducting magnets to have excellent mechanical properties to carry the electromagnetic load during operation. : cable in conduit conductor) structure is widely used by large high-field magnets. Up to now, its internal superconducting cables mainly use low-temperature superconducting wires such as Nb3Sn and NbTi, which are mainly twisted with high-conductivity copper wires in multiple stages to improve the mechanical strength of the cable, reduce its AC loss characteristics, and increase the number of conductors. Margin for safe and stable operation. However, with the development of science and technology, the demand for magnetic field strength in various fields such as electrical engineering, medical treatment, and energy research is getting higher and higher, which leads to the fact that the current conductor technology cannot meet the application requirements of next-generation devices. With the development of practical technology of conductive materials, people gradually turn their attention to the application of high-field magnets to high-temperature superconducting materials with high critical temperature and upper critical magnetic field, such as the second-generation coated conductor REBCO tape, Ag or Ag Alloy-based Bi2212 superconducting wire, etc., but due to differences in material structure, mechanical properties and process requirements, so far, there is still no definite available cable structure and preparation technology.

Based on high-temperature superconducting materials with high-field and high-current-carrying properties, a variety of CICC conductor structure designs have been proposed at home and abroad. Structure, superconducting twisted stack (TSTC) composite structure and spiral wound structure (CORC) and other cable forms, but when applied to high-field CICC conductors, it is prone to high electromagnetic load performance degradation and high AC loss. In order to solve these problems, strengthening the cable with a high-strength sheath and reducing the AC loss characteristics in the form of multi-stage twisting is a method to improve its high-field stable operation characteristics.

Compared with the traditional CICC conductors that use superconducting wires to be directly twisted, there are problems that the cable to be twisted is large in size, high in strength, and difficult to form. In addition, since high-temperature superconducting materials are generally oxide ceramic materials, which have certain stress-strain sensitivity characteristics, it is also necessary to control the uniform deformation during the twisting and forming process of the cable to avoid the local deformation exceeding the allowable range.

Based on this, there are many public reports on the tooling of cable twist forming in the prior art. For example, the Chinese patent application number is: CN201720270478.5, which discloses a wire torsion testing machine, and specifically discloses the following technical difficulties:

The sheath type high strength superconducting cable twisting apparatus as claimed in claim 7, wherein the bottom of the supporting frame is fixedly connected with a supporting frame base, the distance adjusting member comprises an adjusting screw, the adjusting screw is screwed with the supporting frame base at the right side, and the adjusting screw is rotatably connected with the supporting frame base at the left side;

the spacing adjusting piece further comprises a sliding rod body fixedly connected to the left side wheel carrier base, and the sliding rod body is in sliding connection with the right side wheel carrier base.

9. The sheath type high strength superconducting cable twisting apparatus according to claim 1, wherein a plurality of supporting legs are fixedly connected to a bottom of the tooling table.

10. A method for twisting a cable using the sheath-type high-strength superconducting cable twisting apparatus as claimed in any one of claims 1 to 9, comprising the steps of:

(1) fixing the rear end of the cable to be twisted on the cable end locking part, locking the cable, penetrating the cable to be twisted through the twisted cable supporting part, locking the cable, and keeping the twisting stability in the cable twisting process;

(2) assembling and connecting the first half lock disc and the second half lock disc into a whole, combining the first half toothed ring and the second half toothed ring into a complete toothed ring, assembling a driving part at the position adjacent to the toothed ring, supporting a supporting wheel at the lower end of the disc profile of the first half lock disc and the second half lock disc, and driving the toothed ring to carry the locking disc to drive a cable to twist by using the driving part;

(3) and (3) after the automatic twisting in the step (2) is finished, carrying out auxiliary re-twisting on the cable by a plurality of manual cable twisting assemblies.
