Description

Technical Field

[0001] This utility model relates to the field of transformer structure, specifically a new transformer structure. Background Technology

[0002] Transformers are devices that use the principle of electromagnetic induction to change alternating current voltage, playing a vital role in power systems. They are used not only for voltage transformation in power transmission and distribution but also for the stability and security of the entire power system. However, while traditional distribution transformers can meet basic voltage transformation requirements, they have shortcomings in power quality regulation, insulation strength, and manufacturing efficiency. Electronic transformers, although possessing regulation capabilities, are expensive and cannot meet the demand for transformers that combine distribution and regulation functions at a lower cost. Utility Model Content

[0003] The purpose of this utility model is to provide a new transformer structure. This new transformer structure, through innovative design, can solve the shortcomings of traditional distribution transformers in terms of power quality regulation, insulation strength, and manufacturing efficiency. At the same time, it can achieve both power distribution and regulation functions, and reduce production costs to meet the actual needs of the market.

[0004] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a new transformer structure, including a first magnetic yoke ring, a second magnetic yoke ring, and a third magnetic yoke ring arranged in parallel, wherein a plurality of first magnetic pillars are provided between the first magnetic yoke ring and the second magnetic yoke ring, and a plurality of second magnetic pillars are provided between the second magnetic yoke ring and the third magnetic yoke ring, wherein coils are wound on the first magnetic pillars and the second magnetic pillars.

[0005] In some embodiments, the cross-sections of the first magnetic yoke ring, the second magnetic yoke ring, and the third magnetic yoke ring are triangular.

[0006] In some embodiments, there are three first magnetic pillars, located at the three corners of the first magnetic pillar, and three second magnetic pillars, located at the three corners of the second magnetic pillar.

[0007] In some embodiments, the first magnetic yoke ring, the second magnetic yoke ring, and the third magnetic yoke ring are all made of amorphous ribbon.

[0008] In some embodiments, the first magnetic column and the second magnetic column are both iron core columns made of stacked silicon steel.

[0009] In some embodiments, the core post is a cylinder.

[0010] In some embodiments, the height of the second magnetic post is greater than the height of the first magnetic post.

[0011] In some embodiments, the ratio of the magnetic flux of the first magnetic yoke ring, the second magnetic yoke ring, and the third magnetic yoke ring to the magnetic flux of the first magnetic post and the second magnetic post is 0.45 to 0.73.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This novel transformer structure connects the first, second, and third magnetic yoke rings via multiple first and second magnetic pillars, with coils wound on these pillars. This enables the transformer to perform power distribution. By winding coils with different numbers of turns on the first and second magnetic pillars, precise regulation of the output voltage and current can be achieved, thus realizing the transformer's regulation function and achieving a balance between power distribution and regulation. Furthermore, the first, second, and third magnetic yoke rings are made of amorphous strip, while the first and second magnetic pillars are made of stacked silicon steel sheets, giving the transformer high insulation strength and short-circuit withstand capability. Simultaneous winding of the first, second, and third magnetic yoke rings and the coils is also possible, thus addressing the shortcomings of traditional distribution transformers in terms of power quality regulation, insulation strength, and manufacturing efficiency, reducing production costs, and ultimately meeting actual market demands.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] refer to Figure 1-3A novel transformer structure includes a first magnetic yoke ring 1, a second magnetic yoke ring 2, and a third magnetic yoke ring 3 arranged in parallel. The first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 form a basic frame. Multiple first magnetic pillars 4 are provided between the first magnetic yoke ring 1 and the second magnetic yoke ring 2, and multiple second magnetic pillars 5 are provided between the second magnetic yoke ring 2 and the third magnetic yoke ring 3. The first magnetic pillars 4 and the second magnetic pillars 5 provide a path for the conduction of magnetic flux while connecting the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3. Coils 6 are wound on both the first magnetic pillars 4 and the second magnetic pillars 5. By winding coils 6 with different numbers of turns on the first magnetic pillars 4 and the second magnetic pillars 5, different voltage transformation and current regulation functions can be achieved.

[0020] In some embodiments, the cross-sections of the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 are triangular, which can optimize the magnetic flux path and reduce energy loss.

[0021] In some embodiments, there are three first magnetic pillars 4, located at the three corners of the first magnetic pillar 4, and three second magnetic pillars 5, located at the three corners of the second magnetic pillar 5. This can improve the stability of the overall structure, make the magnetic circuit more reasonable, and improve the efficiency of the transformer.

[0022] In some embodiments, the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 are all made of amorphous strip. Amorphous materials have the characteristics of low saturation magnetic flux density and low loss, which can meet the requirements of high energy efficiency applications and solve the problem of high loss when using only silicon steel. The first magnetic column 4 and the second magnetic column 5 are both core columns made of silicon steel. Silicon steel has good short-circuit resistance, which can solve the problem of poor short-circuit resistance of amorphous materials. Through the complementarity of amorphous materials and silicon steel materials, the transformer can maintain high efficiency while also having strong short-circuit resistance.

[0023] Simultaneously, the coil 6 is wound directly on the first magnetic post 4 and the second magnetic post 5, which allows the winding of the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 and the coil 6 on the first magnetic post 4 and the second magnetic post 5 to be carried out synchronously, thereby shortening the processing cycle. At the same time, the overall structure is compact and the short-circuit resistance is improved.

[0024] In some embodiments, the core post can be cylindrical, which facilitates the winding of the coil 6 and improves the uniform distribution of magnetic flux.

[0025] In some embodiments, the height of the second magnetic column 5 may be greater than the height of the first magnetic column 4. By adjusting the height of the second magnetic column 5, the height of the first magnetic column 4, and the height difference between the two, the output voltage and current of the transformer can be adjusted according to actual needs.

[0026] In some embodiments, the ratio of the magnetic flux of the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 to the magnetic flux of the first magnetic pillar 4 and the second magnetic pillar 5 is 0.45 to 0.73. This fully utilizes the characteristics of amorphous materials, such as low saturation magnetic flux density and low loss. By adjusting the width of the amorphous strip of the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3, the loss can be controlled. At the same time, by using different loss distribution ratios between the magnetic yoke rings and the magnetic pillars, the duty cycle of the product can be improved, material costs can be saved, and the performance of the transformer can be optimized, thereby reducing losses.

[0027] The specific working principle is as follows:

[0028] In practice, firstly, based on actual needs, the bandwidth of the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3, the number of turns of the coil 6, and the height of the first magnetic post 4 and the second magnetic post 5 are determined. Silicon steel sheets are stacked to form the first magnetic post 4 and the second magnetic post 5. Then, amorphous ribbon is rolled into the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3. Simultaneously, the coil 6 is wound onto the first magnetic post 4 and the second magnetic post 5 respectively. Then, the first magnetic post 4 is positioned between the first magnetic yoke ring 1 and the second magnetic yoke ring 2, and the second magnetic post 5 is positioned between the second magnetic yoke ring 2 and the third magnetic yoke ring 3.

[0029] When an input voltage is applied to the input terminal of the transformer, current flows through coil 6, generating a magnetic field. This magnetic field is distributed and forms a magnetic circuit in the first magnetic yoke ring 1, the second magnetic yoke ring 2, the third magnetic yoke ring 3, the first magnetic pillar 4, and the second magnetic pillar 5. Since the first magnetic yoke ring 1, the second magnetic yoke ring 2, and the third magnetic yoke ring 3 are all made of amorphous strip material, they possess low saturation magnetic flux density and low loss characteristics, thus reducing transformer losses. Simultaneously, the first magnetic pillar 4 and the second magnetic pillar 5 are made of stacked silicon steel, providing excellent short-circuit withstand capability and improving the transformer's stability.
