There are no restrictions on the materials used in the production of other components except for the iron core. In special working environments, fiberglass is required to be used as the transformer skeleton. The existing fiberglass skeletons are mainly cylindrical winding columns. However, in assembly positions with limited space, the cylindrical winding columns are difficult to fully utilize their functions, and the protection effect on the coils is limited.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings of the specification, but the protection scope of the present invention is not limited thereto. Embodiment

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 , the first technical solution provided by the present invention is: A fiberglass skeleton of an amorphous alloy transformer, including the following technical solutions:

[0019] A glass fiber reinforced plastic (FRP) skeleton for an amorphous alloy transformer, comprising side clamping plates 1 and winding columns 2. The two side clamping plates 1 are respectively welded to the left and right ends of the winding column 2, and pins 5 are welded to the lower ends of the outer side walls of the side clamping plates 1. Plug-in rings 6 are welded to the front and rear sides of the upper part of the outer side walls of the side clamping plates 1. Partition plates 4 are evenly welded to the outer surface of the winding column 2. Connecting pipes 7 are inserted into the inside of the plug-in rings 6. A connecting sleeve 8 is sleeved at the splicing part of the connecting pipes 7. Outer frames 12 are welded to the front and rear sides of the connecting pipes 7. The outer frames 12 are all U-shaped structures, which have a surrounding and wrapping effect on the coil after the coil is wound around the surface of the winding column 2. The winding column 2 is a hollow tube with a core embedded inside. The pins 5 are connected to the core and the subsequent wound coil through internal wires. The wires are pre-embedded into the inside of the side clamping plates 1 and the winding column 2. The whole skeleton is made of FRP material.

[0020] Specifically, an annular flange 9 is integrally formed at the inner end of the outer surface of the connecting pipe 7, and an annular clamping groove 10 is formed on the inner side wall of the connecting sleeve 8.

[0021] Specifically, a stress groove 3 is formed in the middle of the lower side wall of the winding column 2.

[0022] Specifically, side edge plates 11 are integrally formed at the lower ends of the front and rear side walls of the partition plate 4.

[0023] Specifically, the outer frame 12 includes an outer circulation pipe 16. The connecting pipes 7 are welded to both ends of the outer circulation pipe 16, and the connecting pipes 7 communicate with the outer circulation pipe 16. A communicating short pipe 15 is welded between the outer circulation pipes 16, and the two outer circulation pipes 16 communicate with each other through the communicating short pipe 15. A screw joint 13 is screwed to the lower side of the lower outer circulation pipe 16. An outer connecting pipe 14 is welded to the lower end of the screw joint 13. The outer connecting pipe 14 communicates with an external water cooler. The connecting sleeve 8 in this embodiment can be made of rubber material, which can not only play a connecting role, but also seal the connection part of the two connecting pipes 7.

[0024] Working principle:

[0025] The transformer skeleton is made of FRP. The overall shape of its winding column 2 is a cuboid. After winding, the partition plates 4 are used to divide the wire strands of the copper wire, avoiding the problem that all the copper wires on the whole winding column 2 have problems when a single copper wire has problems. The outer circulation pipe 16 connected to the external water cooling equipment can play a small protective effect on the internal coil. At the same time, the circulating water can play an auxiliary heat dissipation effect on the coil, facilitating the coil to maintain a constant working temperature for a long time when overclocking. This transformer skeleton can be used in working environments with special requirements for factors such as magnetic fields, meeting the transformer requirements of special working environments. Embodiment

[0026] Please refer to Figure 1 、 Figure 2 and Figure 4, the difference between the second technical solution provided by the present invention and the first technical solution lies in:

[0027] Specifically, the outer frame 12 includes a protection plate 20. Welding seats 17 are integrally formed at both the front and rear ends of the protection plate 20, and heat dissipation holes 19 are evenly formed in the middle of the protection plate 20. Connecting rods 18 are welded to the inner sides of the welding seats 17, and the connecting pipes 7 are welded to the inner sides of the drying 18.

[0028] Working principle:

[0029] The protection plate 20 of this structure is a fiberglass plate with a thickness of about 8 mm. The heat dissipation holes 19 provided on its side can maintain the heat dissipation effect of the coil to a certain extent. When the transformer is in an exposed working environment, the protection plate 20 can block the surrounding dust and sand, and avoid large debris with a large impulse from hitting the coil of the transformer, playing a protective effect on the coil of the transformer.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
