Problems solved by technology

[0005] However, since the shrinkage rate of the epoxy colloid is larger than that of the superconducting wire body, when the temperature is lowered to the working temperature, due to the strong adhesive force, the epoxy colloid between the turns may tear the multi-layer composite superconducting wire. Cause local damage to the superconducting wire, resulting in degradation of coil performance or overall damage

Abstract

The invention discloses a high-temperature superconduction coil and a fabrication method of the same. The fabrication method comprises the following steps of S1, providing a superconduction wire, and winding the superconduction wire around a winding rack to form a coil; S2, performing vacuum wax immersion processing on the coil so that a gap between turns of the coil is filled with wax; and S3, packaging the coil with an epoxy resin adhesive. According to the fabrication method of the high-temperature superconduction coil, disclosed by the embodiment of the invention, the coil formed by packaging has relatively good heat conduction effect and relatively high mechanical strength, moreover, the superconduction wire is prevented from being locally damaged due to contraction of the epoxy resin adhesive in a low temperature to cause performance degradation of the coil, and the high-temperature superconduction coil is good in performance retentivity and has relatively high performance such as superconductivity and strength.
