Description

Technical Field

[0001] The present 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, transformers are devices that use the principle of electromagnetic induction to change AC voltage. The main components are the primary coil, secondary coil and magnetic core. The main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. For the existing five-winding transformer, two of the 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 and operated. 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. Summary of the Invention

[0008] A mounting piece is fixedly connected to the center position of one side of the first fixing ring away from the wire storage groove. A third flat portion is provided at the bottom of the mounting piece, and a core shaft hole is provided inside the mounting piece. The core shaft hole passes through the first fixing ring, the wire storage groove, and the second fixing ring, and remains flush with the outer wall of the second fixing ring.

[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 installed 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.

[0018] 2. When the coil head is wound, the lead 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 space.

Then, the coil is wound in the wire storage groove 5. After winding is completed, the wire end of the coil is threaded through the lead groove 9 and wound on the winding column 10, so as to connect the wire end with the remaining winding wire ends. The lead groove 9 is used to embed and position the coil, which not only avoids the coil from being scattered and bent, but also avoids occupying additional lead space. Compared with the traditional installation method of directly winding the coil on the mandrel, the installation complexity is reduced, the coil is prevented from being damaged, the insulating wire wound on the skeleton 14 is embedded in the first flying wire groove 7 and the second flying wire groove 8, and is led out through the first flying wire groove 7 and the second flying wire groove 8.
