High-temperature superconducting cable coiling machine and cable coiling method

Abstract

The invention relates to a high-temperature superconductive cable coiler, which comprises track (500), back support (200) for fixing the ball lead screw (400) and superconductive cable, front back support (800) for fixing cable, insulated band lapping machine (700), and superconductive coiling machine (600), wherein the invention also provides a relative method which comprises: lapping the coiled high-temperature superconductive band material on one adjustable leg, and drawing out all the band of feeding disc, according to adjusted angle, to be lapped on the surface of cable skeleton (300) and adhered; the coiling plane (608) formed by band material forms angle (609) with cable skeleton (300), while it is tangent with the plane of cable skeleton (300); the coiling lapping head (603) rotates one time around the axle; and the superconductive band coiling machine is linked to move one length of cable coiling step; and the band material will be packed on the cable skeleton, without torsion angle, to avoid hurting band material caused by over large torsion angle, to damage the superconductivity.

Description

technical field [0001] The invention relates to a high temperature superconducting cable winding device and a cable winding method. Background technique [0002] Due to the inherent characteristics of high-temperature superconducting tapes, there are the following disadvantages when winding high-temperature superconducting tapes in the conventional cable conductor stranding method: [0003] 1. Conventional cable conductor stranding usually adopts tube stranding, cage stranding, frame stranding, beam stranding, etc. There are many types of equipment. Generally, the conductors are made of metal materials such as copper and aluminum. The trays are multi-layered and multi-row stacked. The conductors are straight Stranded together, suitable for twisting of round conductors. The core part of the high-temperature superconducting strip is a powdery ceramic material, which is filled in a metal protective sheath of silver and stainless steel, and drawn by cold pressing. reel. When ...

AI Technical Summary

Problems solved by technology

When the high-temperature superconducting tape is twisted by the conventional cable conductor twisting method, the high-temperature superconducting tape with a thin rectangular cross-section is easily distorted and deformed, which makes the superconducting thin layer inside the tape brittle and destroys its superconducting properties.

[0004] 2. The skeleton of the high-temperature superconducting cable is a stainless steel corrugated tube. When the cable is retracted and unwound, the corrugated tube is elongated by tension, and internal stress will be generated after twisting. If it accumulates to a certain extent, the cable will inevitably be damaged. The conventional cable conductor twisting method is not suitable for high temperature Stranding of superconducting tape
