Abstract

The invention relates to a superconducting coil device and a preparation method thereof. The device comprises a wire base body and a winding body; the wire base body comprises a strip-shaped conductorspirally wound around a longitudinal axis; each turn of the strip-shaped conductor is twisted by 180 DEG in the same direction; the winding body is wound on the strip-shaped conductor; the winding body is wound along the spiral direction of the strip-shaped conductor and is glued to the strip-shaped conductor. The preparation method comprises the following steps that: a strip-shaped conductor iswound along a spiral direction, wherein each turn of the strip-shaped conductor is twisted by 180 degrees; a winding body is wound on the strip-shaped conductor, the strip-shaped conductor is arrangedin a container, and the container is injected with epoxy resin; the strip-shaped conductor is taken out, and redundant epoxy resin is removed; end covers are welded at the two ends of the strip-shaped conductor respectively; a plurality of supporting columns connected with the end covers are arranged, so that the semi-finished product of a superconducting coil can be obtained; and the semi-finished product is arranged into a temperature control furnace so as to be subjected to gelling and curing, and therefore, the finished product of the superconducting coil can be obtained. Therefore, the mechanical stability of the superconducting coil device is improved, and the strain of the superconducting coil device under external interference is reduced.
