Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a transformer structure with a new structure. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. As an important part of the power system, it not only undertakes the basic function of voltage and current conversion, but also plays an important role in improving energy efficiency and environmental protection. Reasonable selection and use of transformers can not only ensure the safe and stable operation of the power system, but also help promote the sustainable use of energy and green development.
[0003] However, the transformer structures currently on the market cannot meet the requirements of large currents. The primary-secondary safety distance is small, the leakage inductance of conventional transformers is small, and LLC requires a larger leakage inductance. The windings of conventional transformer structures are currently wound manually, cannot be produced automatically, and are inefficient. Even if the windings are wound by the same person, the parasitic parameters of the produced transformers are complex, and the consistency of leakage inductance, DCR, and size is also very poor. Transformers wound by different people lack product consistency and cannot meet the needs of automated production. Therefore, a transformer structure with a new structure is needed. Utility Model Content
[0004] The utility model aims to provide a transformer structure with a novel structure, which solves the problem in the prior art that the wire trough of the wire harness plate does not match the number of computer wire strands.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer structure with a new structure, including a primary frame, a CASE is installed on the side of the primary frame, a lower plate is installed parallel to the bottom of the primary frame, a thickened plate is fixedly installed on the surface of the lower plate, a secondary frame is installed on the bottom of the primary frame, a winding post is fixedly installed in the middle of the secondary frame, a positioning plate is fixedly installed on the left side of the winding post, and a copper sheet is arranged on the outside of the winding post.
[0006] Preferably, the sizes of the CASE and the primary framework match each other.
[0007] Preferably, the thickened plate and the lower plate are welded to each other.
[0008] Preferably, the secondary skeleton and the primary skeleton are consistent in size.
[0009] Preferably, the winding post and the secondary frame are welded to each other.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] By setting a thickened plate and a secondary frame, the thickened plate can increase the overall thickness of the lower plate, thereby increasing the distance between the placed primary wire package and the secondary wire package. At the same time, the structure of the secondary frame is different from that of the primary frame, so the safety distance between the primary wire group and the secondary wire group can be increased to achieve a larger leakage inductance.
[0012] A secondary winding is formed by placing copper sheets on the outside of the winding column above the secondary skeleton. The copper sheets have a flat structure and can therefore withstand large currents. Connecting multiple copper sheets in parallel can withstand multiple levels of large currents. In addition, the copper sheets can be produced automatically, reducing the inefficiency of the transformer caused by the morphological differences between different copper sheets.

[0019] 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 in 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.
[0020] Example 1
[0021] like Figure 1-3As shown, a transformer structure with a novel structure includes a primary skeleton 1, a CASE 2 is installed on the side of the primary skeleton 1, a lower plate 3 is installed parallel to the lower side of the primary skeleton 1, a thickened plate 4 is fixedly installed on the surface of the lower plate 3, a secondary skeleton 5 is installed on the bottom of the primary skeleton 1, a winding post 6 is fixedly installed in the middle of the secondary skeleton 5, a positioning plate 7 is fixedly installed on the left side of the winding post 6, and a copper sheet 8 is arranged on the outside of the winding post 6.
[0022] The dimensions of CASE2 and the primary frame 1 match each other. During use, a coil is wound between the lower plate 3 and the primary frame 1 to form a primary winding. CASE2 can provide protective support for the coil placed between the primary frame 1 and the lower plate 3.
[0023] The thickened plate 4 and the lower plate 3 are welded to each other, and thus the thickened plate 4 can increase the overall thickness of the lower plate 3, thereby increasing the distance between the placed primary coil and the secondary coil, thereby obtaining a larger leakage inductance.
[0024] Example 2
[0025] like Figure 4 and Figure 5 As shown, this embodiment further illustrates Example 1, the sizes of the secondary skeleton 5 and the primary skeleton 1 match each other, the secondary skeleton 5 can be spliced and installed under the primary skeleton 1, and the structure of the secondary skeleton 5 is different from that of the primary skeleton 1, so the safety distance between the primary line group and the secondary line group can be increased to achieve a larger leakage inductance.
[0026] The winding post 6 and the secondary skeleton 5 are welded to each other, and a copper sheet 8 can be placed on the outside of the winding post 6 above the secondary skeleton 5 to form a secondary winding. The copper sheet 8 has a flat structure and can therefore withstand large currents. Connecting multiple copper sheets 8 in parallel can withstand multiple levels of large currents, and the copper sheets 8 can be produced automatically, reducing the inefficiency of the transformer caused by the morphological differences between different copper sheets 8.
[0027] Working principle: First, the size of the secondary frame 5 and the primary frame 1 match each other, and the secondary frame 5 can be spliced and installed under the primary frame 1. The structure of the secondary frame 5 is different from that of the primary frame 1, so the safety distance between the primary wire group and the secondary wire group can be increased to achieve a larger leakage inductance. Then, the coil is wound between the lower plate 3 and the primary frame 1 to form the primary winding. CASE2 can provide protective support for the coil placed between the primary frame 1 and the lower plate 3. When winding the primary wire group, the thickened plate 4 can increase the overall thickness of the lower plate 3, so that the placement The distance between the primary coil and the secondary coil is increased, so that a larger leakage inductance can be obtained. Then, a copper sheet 8 is placed outside the winding column 6 above the secondary skeleton 5 to form a secondary winding. The copper sheet 8 has a flat structure, so it can withstand large currents. Connecting multiple copper sheets 8 in parallel can withstand multiple levels of large currents. The copper sheets 8 can be produced automatically, reducing the inefficiency of the transformer caused by the morphological differences between different copper sheets 8. The secondary skeleton 5 has a different structure from the primary skeleton 1, so the safe distance between the primary wire group and the secondary wire group can be increased to achieve a larger leakage inductance.
