The inner winding bracket 1 is inserted into the placement hole 4 from bottom to top, facilitating its installation in the outer winding bracket 2. The inner winding groove 5 and the outer winding groove 6 are separated by the outer side of the outer winding bracket 2 to prevent the coils located in the inner winding groove 5 and the outer winding groove 6 from overlapping, which would affect the transformer's operating efficiency. The first channel 8 facilitates the extension of the coil located on the inner winding groove 5 from the placement hole 4 to the outer winding bracket 2, making it easier for the coil located on the inner winding groove 5 to be connected to the placement part 7.
[0025] In one embodiment, the connection between the placement part 7 and the inner winding bracket 1 is provided with an inclined surface 9. The placement part 7 is located outside the placement hole 4, and the connection between the placement part 7 and the inner winding bracket 1 is provided with an inclined surface 9, so that the first channel 8 is higher, which facilitates the extension of the coil located on the inner winding groove 5 from the first channel 8.

[0028] In one embodiment, the placement portions 7 on both sides of the inner winding bracket 1 have different lengths. The shorter placement portion 7 is connected to the coil located on the inner winding groove 5, and the longer placement portion 7 is connected to the coil located on the outer winding groove 6.

The upper magnetic block 13 and the lower magnetic block 14 have the same structure. The upper magnetic block 13 is provided with a middle magnetic core 18 and an outer magnetic core 19. The middle magnetic core 18 is disposed in a through hole 3. The outer magnetic cores of the upper magnetic block 13 and the lower magnetic block 14 wrap around the outer winding bracket 2, so that the inner coil 15 and the outer coil 16 are located between the middle magnetic core 18 and the outer magnetic core.
[0030] The transformer support of the transformer described in this application is composed of an inner winding support 1 and an outer winding support 2.
