Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and specifically relates to a winding structure of an amorphous alloy transformer. Background Art

[0002] During the operation of a transformer, if a sudden short circuit occurs, since the current suddenly drops from a large value to zero, it will cause a drastic change in the magnetic field at the iron core, and it is very easy to cause the coil to deform. The deformed coil will affect the operation of the transformer and even crush the amorphous alloy iron core. The existing method to reduce coil deformation often adopts the method of coil impregnation with paint, which is relatively troublesome. In addition, there is also a method of adding a skeleton outside the iron core, but the skeleton can only reduce the influence of coil deformation on the iron core and cannot effectively limit the deformation of the coil itself. If a winding structure that can limit the deformation of the coil and protect the iron core can be designed, such problems can be solved. For this reason, we propose a winding structure of an amorphous alloy transformer. Summary of the Invention

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figure 1 、 Figure 2 and Figure 3, the present invention provides a technical solution: an amorphous alloy transformer winding structure, including a housing 1. Annular plates 2 are symmetrically inserted into the upper and lower cavities of the housing 1. The annular plates 2 limit the positions on the upper and lower sides of the coil. A cylindrical tube 3 is inserted between the two annular plates 2. The cylindrical tube 3 protects the first iron core column 5 and the second iron core column 6, and the cylindrical tube 3 limits the position and deformation of the inner periphery of the coil. A circular plate 4 is assembled on the inner side wall of the cylindrical tube 3. The circular plate 4 separates the first iron core column 5 and the second iron core column 6. The first iron core column 5 is inserted into the inner side wall of the cylindrical tube 3 above the circular plate 4, and the second iron core column 6 is inserted into the inner side wall of the cylindrical tube 3 below the circular plate 4. A high-voltage coil 7 is wound around the outer side wall of the cylindrical tube 3. A low-voltage coil 8 is wound around the outer side wall of the high-voltage coil 7. A limiting cylinder 9 is sleeved on the outer side wall of the low-voltage coil 8. The limiting cylinder 9 is made of a metal material with good heat conduction performance. The limiting cylinder 9 limits the position and deformation of the outer periphery of the coil. Rectangular holes 10 are evenly opened on the upper side wall of the annular plate 2. Insert blocks 11 are symmetrically and evenly fixedly installed on the upper and lower side walls of the limiting cylinder 9, and the insert blocks 11 are inserted into the rectangular holes 10. Through the cooperation of the insert blocks 11 and the rectangular holes 10, the annular plate 2 and the limiting cylinder 9 play a role in mutually limiting their positions. Furthermore, the annular plate 2, the limiting cylinder 9 and the cylindrical tube 3 limit the positions of the high-voltage coil 7 and the low-voltage coil 8. At the same time, under the action of the cylindrical tube 3 and the limiting cylinder 9, it is difficult for the coil to deform.

[0017] Specifically, an annular groove 12 is opened on the inner side wall of the cylindrical tube 3. An annular insulating plate 13 is fixedly installed on the inner side wall of the annular groove 12, and the circular plate 4 is fixedly installed on the inner side wall of the annular insulating plate 13. The position of the circular plate 4 can be limited through the annular groove 12. The annular insulating plate 13 plays an insulating role to prevent the current at the coil from conducting to the iron core.

[0018] Specifically, fixing rings 14 are evenly fixedly installed on the inner side wall of the cylindrical tube 3. Rubber rings 15 are fixedly installed on the inner side walls of the fixing rings 14, and the inner side walls of the rubber rings 15 are respectively attached to the outer side walls of the first iron core column 5 and the second iron core column 6. The positions of the first iron core column 5 and the second iron core column 6 are limited through the fixing rings 14 and the rubber rings 15. The material of the rubber ring 15 is relatively soft and will not damage the first iron core column 5 and the second iron core column 6. Moreover, the rubber ring 15 is an insulating material, which can prevent the current at the coil from conducting to the iron core.

[0019] Specifically, a rubber pad 16 is fixedly installed on the inner side wall of the annular plate 2, and the inner side walls of the rubber pad 16 are respectively attached to the outer side walls of the first iron core column 5 and the second iron core column 6. The function of the rubber pad 16 here is the same as that of the rubber ring 15, playing a role in protection and insulation.

[0020] Specifically, a cooling air duct 17 is provided inside the outer shell 1. A fan is installed on the transformer, and the fan blows air to flow inside the cooling air duct 17, thereby promoting heat dissipation and cooling the coil. Metal rods 18 are evenly inserted into the inner side wall of the outer shell 1, and the metal rods 18 are inserted into the cooling air duct 17. A sealing ring 20 is fixedly installed at the right end of the outer side wall of the metal rod 18. As Figure 3 shown, the sealing ring 20 can prevent the air inside the cooling air duct 17 from flowing into the inside of the outer shell 1. A heat conducting block 19 is fixedly installed at the inner end of the metal rod 18, and the inner side wall of the heat conducting block 19 is attached to the outer side wall of the limiting cylinder 9. The heat generated by the coil when passing through the current will be conducted to the metal rod 18 through the transmission of the limiting cylinder 9 and the heat conducting block 19. Since the metal rod 18 is located inside the cooling air duct 17, it can directly exchange heat with the air, promoting heat dissipation.

[0021] Specifically, cushion blocks 21 are evenly and fixedly installed on the lower side wall of the outer shell 1, and the cushion blocks 21 support the entire device.

[0022] Working principle: In this amorphous alloy transformer winding structure, the first iron core column 5 and the second iron core column 6 are respectively located on the upper and lower sides of the inner circular plate 4 of the cylindrical barrel 3. The cylindrical barrel 3 is cooperatively and fixedly supported by the fixing ring 14 and the rubber ring 15 to effectively protect the first iron core column 5 and the second iron core column 6. In addition, under the mutual insertion and limiting action between the annular plate 2 and the limiting cylinder 9, in cooperation with the cylindrical barrel 3, the high-voltage coil 7 and the low-voltage coil 8 are clamped and their positions are limited. When a short circuit occurs in the transformer, it is difficult for the coil to deform under the limitation, playing a role in protecting the coil, the iron core and the transformer. At the same time, under the heat conduction of the limiting cylinder 9 and the heat conducting block 19, the heat generated by the coil can be conducted to the metal rod 18 located inside the cooling air duct 17, thereby achieving the effect of promoting heat dissipation and enabling the transformer equipped with this structure to operate better.
