Embodiment Construction

[0016] The accompanying drawing shows an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawing and the embodiment.

[0017] It can be seen from the accompanying drawings that the present invention is a method for manufacturing a superconducting strip insulation layer of a high-temperature superconducting transformer and a manufacturing device thereof. A method of wrapping polyimide film tape along the longitudinal direction of the superconducting tape is adopted, through the self-adhesive polyimide film tape wrapping system, the superconducting tape is directly wrapped with a layer of self-adhesive polyimide film longitudinally along the wire axis The imide film tape makes the insulation strength between coil turns and cakes meet the requirements of 500V power frequency withstand voltage test. The size of the polyimide film is: width 8-12mm, thickness 0.1-0.2mm. The specific production metho...

Abstract

The invention is a method and device for making polyimide film-superconductive tape insulating structure, adopting rolled self-adhesive polyimide film tape and rolled superconductive wire, before the rolled superconductive wire is fed in an insulator coating device, lengthways pasting the rolled self-adhesive polyimide film tape on the rolled superconductive wire in the axial direction of the superconductive wire by a self-adhesive polyimide film tape roller, then feeding the superconductive wire into the insulator coating device so that the insulator coating device lengthways coat the self-adhesive polyimide film tape on the superconductive wire in the axial direction of the superconductive wire. The whole system comprises uninsulated wire coiling frame, polyimide film line coiling frame, insulator coating device and insulated superconductive wire coiling frame, where the polyimide film line coiling frame is arranged between the uninsulated wire coiling frame and the insulator coating device, and as passing through the polyimide film line coiling frame, the superconductive wire is in the middle of the polyimide film and the polyimide film-coated superconductive wire coiling frame is behind the insulator coating device.

Description

technical field [0001] The invention belongs to a method for manufacturing a material for a high-temperature superconducting transformer, in particular to a method for manufacturing an insulating layer of a superconducting strip used for coils of a high-temperature superconducting transformer; the invention also relates to a method for manufacturing the insulating layer of the superconducting strip production tooling equipment. Background technique [0002] In a conventional transformer, there is a layer of insulation layer on the wire, and the insulation strength is large enough, so there is no need to consider additionally strengthening the insulation strength of the wire. However, in the development of high-temperature superconducting transformers in China, Bi2223 / Ag superconducting tape produced by Beijing Inner Superconducting Co., Ltd. is currently mostly used. This superconducting tape has a wire gauge of 4.2mm×0.23mm and a small thickness. It is difficult for the in...
