Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically a high-voltage-resistant transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction generated by coils and iron cores to change AC voltage. It is often used in circuit structures to play a role in voltage transformation. However, when the circuit structure is subjected to external pressure, the transformer is easily damaged, which can affect its voltage transformation function or even cause it to fail.

[0003] To address the above shortcomings, we need to develop a high-voltage transformer to meet the needs of a wide range of users. Utility Model Content

[0004] In response to the aforementioned problem that existing transformers are easily damaged, affecting their use or causing them to fail, the technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A high-voltage transformer includes a frame and a magnetic core mounted on the frame. The frame has three primary windings and two secondary windings near the magnetic core. The primary windings and the secondary windings are wound together in one layer, so that the frame forms a four-layer winding structure from the inside out. The surface of each winding structure is covered with an insulating layer.

[0006] As described above, a high-voltage transformer has a frame including an input side a and an output side b. The frame has at least 8 pins on the input side a and the output side b respectively. The pins can be passed through by the primary winding or the secondary winding.

[0007] As described above, in a high-voltage transformer, the pins located on the input side a serve as input pins, and the pins located on the output side b serve as output pins.

[0008] As described above, in a high-voltage transformer, the primary winding is wound between different pins.

[0009] As described above, in a high-voltage transformer, the secondary winding is wound between different pins.

[0010] In the high-voltage transformer described above, the pins are fitted with insulating sleeves.

[0011] As described above, in a high-voltage transformer, the pins are arranged alternately along a straight line c and along a straight line d, with the straight line c being parallel to the straight line d, and a spacing A between the straight line c and the straight line d, the spacing A being between 29mm and 30mm.

[0012] In the high-voltage transformer described above, the pin pitch B between adjacent pins ranges from 3.4 mm to 4.1 mm.

[0013] As described above, in a high-voltage transformer, the frame adopts an EQ-type frame structure, the maximum length C of the magnetic core is less than or equal to 24.5 mm, the maximum height D of the magnetic core is less than or equal to 17.5 mm, and the maximum width E of the frame is less than or equal to 34 mm.

[0014] As described above, a high-voltage transformer has at least two insulating layers covering the surface of each winding structure.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes a production process that involves layering insulation layers to wrap each winding structure to form a film-coated wire, thereby increasing the withstand voltage and improving the wire's performance. Compared to traditional transformer winding structures, the overall transformer winding structure of this invention offers superior performance. Furthermore, compared to transformers of similar power, the transformer winding structure of this invention is smaller in size and lower in cost. Attached Figure Description

[0022] Figure 6 A reference diagram of the EQ series skeleton structure is provided. Detailed Implementation

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] Figures 1 to 5The high-voltage transformer shown in Embodiment 1 includes a frame 100 and a magnetic core 200 mounted on the frame 100. The frame 100 has three primary windings N1, N2, and N3 and two secondary windings N4 and N5 near the mounting position of the magnetic core 200. The primary winding N3 and the secondary winding N4 are wound together in one layer, so that the frame 100 forms a four-layer winding structure from the inside to the outside. The surface of each winding structure is covered with an insulating layer 400.

[0025] Specifically, in this embodiment, the skeleton 100 preferably adopts an EQ series skeleton structure (see...). Figure 6 This EQ-type frame structure has a first substrate 101, a second substrate 102, and a core mounting channel 103. The hollow, through-hole core mounting channel 103 is located between the first substrate 101 and the second substrate 102. The first substrate 101 can be used to set several pin structures. The transformer power of this embodiment is between 30W and 50W. The core 200 of this embodiment can be divided into a first core 201 and a second core 202 used in conjunction. The primary winding is used to receive the voltage and current provided by the power supply, and the secondary winding is used to receive the voltage and current provided by the power supply. Winding is used to provide voltage and current to the load. Primary windings N1, N2, and N3, and secondary windings N4 and N5 are wound around the outside of the core mounting channel 103 of the frame 100. The primary winding N3 and secondary winding N4 are wound in a single layer, forming a first layer of winding structure N1, a second layer of winding structure N2, a third layer of winding structure N3+N4, and a fourth layer of winding structure N5, respectively, wound sequentially from the outer surface of the core mounting channel 103 towards the outside (see...). Figure 4 (The PIN in the diagram represents the bottom position near the pin of the first substrate 101, and the TOP in the diagram represents the top position near the pin of the second substrate 102). More specifically, the surface of each winding structure is wrapped with an insulating layer 400, which enhances the withstand voltage and improves the wire performance while meeting the normal voltage conversion function.

[0026] Furthermore, based on Example 1, Figure 4 Another preferred embodiment 2 of the transformer is shown, wherein the surface of each winding structure is covered with at least two insulating layers 400, which can be tape or adhesive paper, preferably layered tape.

[0027] Furthermore, based on Example 1, Figure 3 and Figure 5Another preferred embodiment of the transformer is shown in section 3. The frame 100 includes an input side a and an output side b. The frame 100 has at least eight pins 1; 2; 3; 4; 5; 6; 7; 8 on the input side a and the output side b respectively. The pins 1; 2; 3; 4; 5; 6; 7; 8 can be wound through by the primary winding or the secondary winding. Among them, the pins 1; 2; 3; 4; 5 are located on the input side a as input pins, and the pins 6; 7; 8 are located on the output side b as output pins.

[0028] Primary winding N1 is wound between pins 3 and 2; primary winding N2 is wound between pins 8 and 6; primary winding N3 is wound between pins 7 and 6.

[0029] Secondary winding N4 is wound between pins 5 and 4, and secondary winding N5 is wound between pins 2 and 1.

[0030] Specifically, in this embodiment, the first substrate 101 of the frame 100 has slots 104 for wire threading between adjacent pins. This winding structure can achieve a better transformer performance. Compared with transformers of the same power, this winding structure can achieve a smaller size and lower cost. More specifically, the winding sequence of the winding structure is as follows:

[0031] The primary winding N1 starts from pin 3 in slot 104 between pins 3 and 4, passes through slot 104 between pins 2 and 3, and ends at pin 2, with 23 turns and 2 layers of close winding.

[0032] The primary winding N2 starts from pin 8 in slot 104 between pins 7 and 8, passes through slot 104 between pins 6 and 7, and ends at pin 6, with 18 turns and 2 layers of close winding.

[0033] The primary winding N3 starts from pin 7 in slot 104 between pins 7 and 8, passes through slot 104 between pins 6 and 7, and ends at pin 6, with a total of 6 turns. The primary winding N4 starts from pin 5 in slot 104 between pins 4 and 5, passes through slot 104 between pins 4 and 5, and ends at pin 4, with a total of 8 turns. It is wound in one layer with the primary winding N3.

[0034] The primary winding N5 starts from pin 2 in slot 104 between pins 2 and 3, passes through slot 104 between pins 1 and 2, and ends at pin 1, with 23TS turns and one layer of close winding.

[0035] Preferably, two layers of insulating tape are used to isolate each winding structure.

[0036] Furthermore, based on Example 1, Figure 5 Another preferred embodiment 4 of the transformer is shown, in which pins 7 are fitted with insulating sleeves 300.

[0037] Furthermore, based on Example 1, Figure 3 Another preferred embodiment of the transformer is shown in 5, where pins 1, 2, 3, 4, and 5 are arranged sequentially along a straight line c, and pins 6, 7, and 8 are arranged sequentially along a straight line d. The straight lines c and d are parallel, and a spacing A is formed between the straight lines c and d. The spacing A ranges from 29 mm to 30 mm, and is preferably 29.5 mm.

[0038] The value of the stitch distance B between adjacent stitches 1, 2, 3, 4, 5, 6, 7, and 8 is between 3.4 mm and 4.1 mm, with 3.75 mm being the preferred value.

[0039] Specifically, in this embodiment, the pin structure adopts a row spacing A to improve the safety distance by widening the secondary side, which effectively prevents high voltage failure and eliminates the secondary bushing, making it less prone to failure during use, improving safety and service life, saving production costs in the production process, and improving the economic benefits of the product.

[0040] Furthermore, based on Example 1, Figure 1 and Figure 2 Another preferred embodiment of the transformer is shown in 6, where the maximum length C of the magnetic core 200 is less than or equal to 24.5 mm, the maximum height D of the magnetic core 200 is less than or equal to 17.5 mm, and the maximum width E of the frame 100 is less than or equal to 34 mm. This shape structure can achieve a smaller size and lower cost compared to transformers of the same power.
