High temperature superconductor coil and winding technology thereof

Abstract

The invention discloses a high temperature superconductor coil and a winding technology of the high temperature superconductor coil. The high temperature superconductor coil comprises an epoxy barrel and a plurality of layers of coil units, wherein each coil unit is composed of a low temperature glue layer, a polyimide film layer and a superconduction strip layer which are arranged in sequence. According to the winding technology, firstly, a framework of the superconductor coil is well fixed, winding positions are marked, the surface of the framework is evenly coated with low temperature glue and wound with polyimide films, then polyimide belts are laid at equal intervals, tensioned and fixed, after a strip winding disc is prepared, the wire inlet end is fixed to the surface of the framework and is evenly and densely wound with a layer of superconduction strips, then the surface of each strip is coated with the low temperature glue and wound with a layer of polyimide films, the polyimide belts are tensioned and laid backwards, and all the operations are repeated until the whole coil is wound. It is guaranteed that certain prestress is applied to the superconduction strips, layer insulation is achieved through the polyimide films and the low temperature glue, and the winding technology is simple and effective on the basis of ensuring the performance of the strips effectively.

Description

technical field [0001] The invention relates to a high-temperature superconducting coil, in particular to a high-temperature superconducting coil and a winding process thereof. Background technique [0002] With the rapid development of my country's economy, the electricity consumption in many cities is increasing year by year, the power load in the central area of ​​the city has increased sharply, the transmission and distribution capacity has increased significantly, and issues such as reducing power grid losses and improving power grid operation stability have also been raised. At present, the power grid system loses a lot in the power transmission and distribution link, so all countries are looking for solutions to reduce power grid losses. Among them, superconducting materials are one of the most important solutions to reduce power grid losses. Superconducting materials have low loss, high efficiency, and high transmission current density. High advantages are of great s...
