Abstract
Description
Technical Field
[0001] The present application relates to the technical field of transformer cores, and more specifically, to a transformer core with strong stability. Background Art
[0002] The windings and core in the transformer are closely related, and they work together to achieve voltage transformation. The core is the core component of the transformer, which provides a magnetic flux path, allowing the transformer to efficiently transform voltage. The core is usually made of stacked silicon steel sheets to reduce hysteresis loss and eddy current loss. The windings are coils wound around the core, and the windings are usually made of insulated copper or aluminum wires. When they pass current, they generate a magnetic field, which interacts with the magnetic field of the core to achieve voltage transformation.
[0003] In the actual operation of the transformer, due to mechanical stress loosening or aging after long-term use, the coil wound on the iron core will become loose. Once the winding coil becomes loose, it will cause the transformer to operate abnormally, and in serious cases, it will cause leakage or fire accidents. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 2 As shown, the transformer core with strong stability provided by the embodiment of the present application includes multiple silicon steel sheets 100, a first U-shaped plate 300, a second U-shaped plate 500, a well frame 700 and a positioning bolt 800, wherein multiple silicon steel sheets 100 are stacked together in a specific manner to form the iron core of the transformer, and each silicon steel sheet 100 is provided with a rectangular hole 200 in the thickness direction, and the electromagnetic coil is wound on the rectangular hole 200 of the silicon steel sheet 100 to form a winding. In the actual operation of the transformer, due to long-term use, mechanical stress loosening or aging may occur, causing the coil wound on the iron core to loosen.
[0026] The first U-shaped plate 300 is a plate structure with a U-shaped structure, and the groove width of the first U-shaped plate 300 is adapted to the thickness of the iron core formed after a plurality of silicon steel sheets 100 are stacked. The first U-shaped plate 300 is fixedly arranged on the hole wall in the width direction of the rectangular hole 200, and the inner wall surface of the first U-shaped plate 300 is in contact with the wound coil. In addition, the outer surface of the first U-shaped plate 300 is also provided with a first positioning hole 400, and the first positioning hole 400 is located at both ends of the length direction of the first U-shaped plate 300. Preferably, the length of the first U-shaped plate 300 is less than the hole wall length in the width direction of the rectangular hole 200.
[0027] Similarly, the second U-shaped plate 500 is also a plate structure with a U-shaped structure, and the groove width of the second U-shaped plate 500 is adapted to the thickness of the iron core formed after multiple silicon steel sheets 100 are stacked. The second U-shaped plate 500 is fixedly arranged on the hole wall in the length direction of the rectangular hole 200, and the inner wall surface of the second U-shaped plate 500 is in contact with the wound coil. In addition, the outer surface of the second U-shaped plate 500 is also provided with a second positioning hole 600, and the second positioning hole 600 is located at both ends of the second U-shaped plate 500 in the width direction. Preferably, the length of the second U-shaped plate 500 is less than the hole wall length in the length direction of the rectangular hole 200.
[0028] In this embodiment, the well frame 700 is arranged in the rectangular hole 200, and the multiple ends of the well frame 700 are respectively inserted into the first positioning hole 400 and the second positioning hole 600. Preferably, the well frame 700 can be made of a heat-conductive material. The positioning bolt 800 is fixed on the surface of the well frame 700, and the positioning bolt 800 is located beside the first U-shaped plate 300 and the second U-shaped plate 500. The positioning bolt 800 also contacts the first U-shaped plate 300 and the second U-shaped plate 500 to abut the two against the coil, thereby preventing the coil from loosening.
[0029] In the transformer core with strong stability provided in the embodiment of the present application, the ends of the well frame 700 are respectively inserted into the first positioning hole 400 of the first U-shaped plate 300 and the second positioning hole 600 of the second U-shaped plate 500, and the positioning bolts 800 are fixed to the well frame 700 at positions close to the first U-shaped plate 300 and the second U-shaped plate 500, so as to achieve the purpose of abutting the first U-shaped plate 300 and the second U-shaped plate 500 with the coil through the positioning bolts 800. The above structural design can prevent the coil from falling off and causing abnormal operation of the transformer, thereby causing leakage or fire accidents, thereby effectively improving the stability of the transformer during operation.
[0030] In some embodiments, the surfaces of the first U-shaped plate 300 and the second U-shaped plate 500 are both provided with a fan 900. Specifically, the fan 900 can be embedded in the surfaces of the first U-shaped plate 300 and the second U-shaped plate 500, and the fan 900 can blow air to the first U-shaped plate 300 and the second U-shaped plate 500 on the opposite side. Since the first U-shaped plate 300 and the second U-shaped plate 500 are directly in contact with the coil, the fan 900 can cool the first U-shaped plate 300 and the second U-shaped plate 500 by blowing air.
[0031] On the basis of the above embodiment, the fans 900 of the first U-shaped plate 300 opposite to each other are in a staggered distribution structure, and similarly, the fans 900 of the second U-shaped plate 500 opposite to each other are also in a staggered distribution structure. In this way, the fans 900 can be directly aimed at the plate surfaces of the first U-shaped plate 300 and the second U-shaped plate 500 to blow air, thereby further improving the heat dissipation efficiency.
[0032] In some embodiments, two fans 900 are disposed on each of the first U-shaped plate 300 and the second U-shaped plate 500 , and the two fans 900 are symmetrically distributed on the surfaces of the first U-shaped plate 300 and the second U-shaped plate 500 with the well frame 700 as the axis of symmetry.
