Fixing structure of annular air-core reactor

The invention relates to a fixing structure of an annular air-core reactor. The fixing structure comprises a large fixing ring, a wire cake and a small fixing ring, two small fixing rings are symmetrically arranged on the front side and the rear side of the large fixing ring, a plurality of wire cakes are evenly arranged on the large fixing ring in a sleeving mode in the circumferential direction, and the small fixing rings are arranged in the wire cakes in a sleeving mode; the wire cake comprises a winding ring and a high-voltage coil wound on the winding ring; fixing plates are arranged at upper and lower quadrant points on the inner circumferential side of the wire cake; the fixing plates are connected with the large fixing ring through plug pins; a plurality of clamping grooves for accommodating the inner side edges of the winding rings are formed in the small fixing rings, and the small fixing rings are bound and fixed with the winding rings through insulating ribbons; the fixing structure is good in sta
