Description

Technical Field

[0001] The invention relates to the technical field of transformer windings, and in particular to a wire storage fixture and a transformer winding. Background Art

[0002] With the continuous development of current technology, the transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the magnetic core. The main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. For the existing transformer with five windings, two windings need to share a wire. The current method is to directly wind the coil wire end section on the equipment shaft core after winding one winding. This method requires the coil winding to be placed on the core shaft before the next connection can be achieved. Multiple processes cannot be decomposed for operation. The operation steps are cumbersome. In addition, the coil is directly wound on the core shaft, and there is a risk of scratching and damaging the wire between the coil and the core shaft.

[0009] Furthermore, the thickness of the first fixing ring is greater than that of the second fixing ring, and the first fixing ring and the second fixing ring are integrally formed.

[0010] Furthermore, it also includes a frame, which is detachably mounted between the mounting piece and the first fixing ring.

[0011] Furthermore, an insulating wire groove is provided on the outer wall of the frame, and a mounting hole is provided at the center of the frame. The frame and the first fixing ring are installed by inserting the mounting piece into the mounting hole, and when the mounting piece is inserted into the mounting hole, a gap hole is formed between the two.

[0012] Furthermore, a positioning piece matched with the positioning groove is fixedly connected to the bottom of the side wall of the skeleton facing the first fixing ring.

[0018] 2. When the coil head is wound, the lead wire groove is provided to facilitate the insertion and positioning of the coil, which not only prevents the coil from being scattered and bent, but also prevents it from occupying additional lead wire space.
