Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically a winding structure for a photonic crystal bundle high-frequency transformer. Background Technology

[0002] High-frequency transformers are transformers that operate at frequencies higher than traditional power frequencies. They are commonly used in circuits ranging from tens of kilohertz to megahertz. Their core applications include power electronics conversion for high-frequency power conversion in switching power supplies and high-frequency DC-DC converters; signal transmission, impedance matching, and circuit isolation and anti-interference in radio frequency circuits in the field of communication and signal processing; and high-frequency energy transmission in induction heating and wireless charging systems in the fields of new energy and special power supplies.

[0003] Traditional high-frequency transformers have cumbersome connection cables. The complex and intertwined cables make the installation process time-consuming and labor-intensive, increasing labor costs and construction cycles. Moreover, during later maintenance, it is difficult to troubleshoot the lines, locate and repair faults, and prolong equipment downtime. The complicated cable connections are prone to generating large distributed capacitance and inductance. The complexity of the cable connections also limits the flexibility and scalability of the system, making it difficult to quickly adapt to different application scenarios and functional requirements, thus hindering the efficient application of high-frequency transformers in emerging fields.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0024] A high-frequency transformer winding structure for a photonic crystal beamline includes an E-type core 1. Multiple pins A3 and B20 are mounted on the upper surface of the E-type core 1. Connecting plates 4 are mounted on the outer surfaces of pins A3 and B20. Multiple wire holes 5 are opened on the outer surface of each connecting plate 4. Multiple tightening screws 6 are mounted on the upper surface of each connecting plate 4. The interior of each wire hole 5 is connected to the bottom of the tightening screw 6. A sealing plate 2 is connected to the bottom surface of the E-type core 1. Multiple fixing feet 7 are mounted on the outer surface of the sealing plate 2. A washer 8 is mounted on the bottom surface of each fixing foot 7. After the wire passes through the wire hole 5, it is fixed by the tightening screw 6, ensuring stable electrical connection, reducing contact resistance and signal loss, and providing a convenient interface for winding and circuit wiring. The sealing plate 2, fixing feet 7, and washer 8 securely install the transformer in the equipment, preventing loosening of the connection due to vibration or other factors during operation, and ensuring operational reliability.

[0025] In this embodiment, two heat dissipation fins 9 are installed on the outer surface of the E-type iron core 1. Each heat dissipation fin 9 is equipped with a cooling fan 10 on its outer surface. The cooling fan 10 removes heat in time to avoid performance degradation or insulation aging due to overheating.

[0026] In this embodiment, the outer surface of the E-type iron core 1 is connected to a first insulating layer 19, which is an organic insulating material that can effectively provide insulation.

[0027] In this embodiment, a first coil 18 is connected to the outer surface of the first insulating layer 19. The first coil 18 is a copper wire with good conductivity, which can provide excellent conductivity and ensure efficient energy transmission.

[0028] In this embodiment, the outer surface of the first coil 18 is connected to a heat insulation layer 17, which is a rock wool heat insulation material. The main components of rock wool are inorganic minerals such as basalt and slag. It has a melting point of over 1000°C and will not burn or release toxic gases in a fire, nor will it deform or collapse due to high temperature.

[0029] In this embodiment, a secondary coil 16 is connected to the outer surface of the heat insulation layer 17, and a second insulating layer 15 is connected to the outer surface of the secondary coil 16. The multi-level coil turns can meet the voltage and current requirements of different circuits.

[0030] In this embodiment, a fastening layer 14 is connected to the outer surface of the second insulating layer 15, and a three-stage coil 13 is connected to the outer surface of the fastening layer 14. The fastening layer 14 enhances the strength of the winding structure, prevents the wire turns from loosening, and improves the overall structural stability.

[0031] In this embodiment, a shielding layer 12 is connected to the outer surface of the three-stage coil 13, and a heat dissipation layer 11 is connected to the outer surface of the shielding layer 12. The heat dissipation layer 11 can effectively dissipate heat.

[0032] Working Principle: The E-type iron core 1 serves as the main body of the magnetic circuit. When energized, current flows through pins A3 and B20, and through the connecting plate 4 and wire hole 5, connecting to the first coil 18, the second coil 16, and the third coil 13. This generates an alternating magnetic field within the E-type iron core 1. Based on electromagnetic principles, different numbers of turns achieve voltage transformation, completing the transmission and conversion of high-frequency electrical energy to meet the voltage and current requirements of different circuits. After the wire passes through the wire hole 5, it is fixed by the tightening screw 6 to ensure stable electrical connection, reduce contact resistance and signal loss, and provide a convenient interface for winding and wiring. The sealing plate 2, fixing feet 7, and gaskets 8 securely install the transformer on the device. To prevent loosening of connections due to vibration and other factors during operation and ensure operational reliability, the heat generated by the coils and core during operation is dissipated naturally by increasing the heat dissipation area through the heat dissipation fins 9 on the outer surface of the E-type core 1. On the other hand, the cooling fan 10 removes the heat in time, preventing performance degradation or insulation aging due to overheating. The first insulation layer 19 and the second insulation layer 15 are made of organic insulating materials to effectively isolate the coils and prevent leakage and short circuits. The shielding layer 12 suppresses electromagnetic interference and reduces the influence of the internal electromagnetic field on external equipment. The fastening layer 14 enhances the strength of the winding structure, prevents the coils from loosening, and improves the overall structural stability.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
