The utility model content
The technical problem that the utility model will solve is, provides a kind of simple in structure, and can apply bigger pressure and be used for the dry type frequency control of fastening winding with the winding fastening structure of rectifier transformer.
The technical scheme of the utility model is; The frequency control of the utility model dry type is with the winding fastening structure of rectifier transformer; It comprises briquetting, and an end face of briquetting is used for offseting with the end face of winding fastening end, and it also comprises bolt; The bar portion of bolt is used for being threaded with the strutting piece of dry type frequency control with rectifier transformer, and the end face of the head of bolt and the other end of briquetting offset; The end face of said head is provided with convexity, and it is same straight line that the axis of said protruding symmetry axis place straight line and bar portion belongs to straight line, and the depression that is provided with on the other end of this convexity and said briquetting matches.
After adopting said structure, the utility model compared with prior art has the following advantages: the frequency control of the utility model dry type is few with the component structural of the winding fastening structure of rectifier transformer; Connect simple and reliable; Because the face area of head is bigger, like this, can applies bigger pressure and be used for fastening winding; So the utlity model has simple in structurely, and can apply bigger pressure and be used for the advantage of fastening winding.
As improvement, said convexity is cylinder or circular cone or hemisphere, this type convex shape rule; Processing is simple; Good, radially accurately and reliably spacing with depression that is provided with on the connected piece or the rotatable back intensity that cooperates of breach or hole, more help the raising of the performance of the utility model.
As further improvement, it also comprises the pad that is provided with centre bore, and pad matches with said depression, and the centre bore of pad matches with said convexity; The offset end face that is meant pad and the other end of briquetting of the end face of the head of said bolt and the other end of briquetting offsets; The other end of pad and the inner bottom surface of depression offset, and be convenient for assembly like this, easy to adjust.
As further improvement; Be with spring washer in the said bar portion, be rotary with nut, an end face of spring washer is used for offseting with strutting piece, and the other end and the nut of spring washer offset; After the distance between strutting piece and the briquetting of bolt is adjusted; The nut of screwing again helps keeping this segment distance, makes fastening winding reliable.
