Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and more particularly to rectifier transformers. Background Technology
[0002] Rectifier transformers play a vital role in power systems. During their operation, they generate a large amount of heat. If this heat cannot be effectively dissipated, it will affect the normal operation of the rectifier transformer and may even cause a malfunction. Therefore, how to effectively dissipate heat is an important issue in the design of rectifier transformers.
[0003] Traditional devices often rely on single heat sink fins or simple fans for cooling, resulting in low heat dissipation efficiency. Especially in high-temperature environments or under high loads, insufficient heat dissipation often leads to overheating, shortening the equipment's lifespan. Furthermore, when outside air directly enters the casing, dust, moisture, and other impurities easily adhere to the surfaces of electrical components, affecting heat dissipation and potentially causing safety hazards such as decreased insulation performance and short circuits. While some devices are equipped with dust filters or moisture-absorbing materials, dust filters are easily clogged by debris, requiring frequent manual disassembly and cleaning. Moisture-absorbing materials need periodic replacement once saturated, leading to high maintenance costs and frequent replacements disrupting continuous equipment operation. Therefore, a rectifier transformer is proposed to address these issues. Utility Model Content

[0013] Three beneficial effects
[0014] Compared with the prior art, the present invention provides a technical solution with the following beneficial effects:
[0015] 1. This utility model achieves efficient heat dissipation and air purification through devices such as dustproof nets, activated carbon plates, connecting pipes, air guide seats, and axial flow fans. The axial flow fan delivers air on one side and exhausts air on the other side, accelerating the airflow inside the casing. The connecting pipe connects to the axial flow fan via an air collector hood, and multiple annular equidistant air guide seats on the outside send air into the casing from multiple directions, allowing the airflow to cover the internal components more evenly and greatly improving heat dissipation efficiency. At the same time, the dustproof nets and activated carbon plates filter impurities and moisture, ensuring the internal environment.

This utility model realizes the regeneration of activated carbon plates and automatic cleaning of dust screens through devices such as a fixed frame, heating tube, fixed bracket, electric push rod, and brush. The heating tube on the fixed frame, in conjunction with the axial flow fan reversing, can heat and dry the activated carbon plates to complete the regeneration. The electric push rod on the fixed bracket drives the brush of the cleaning bracket to move back and forth, which can clean the dust screen impurities, reduce manual maintenance, ensure the continuous and stable operation of the device, and reduce the cost of use.

[0023] This utility model provides a technical solution:
[0024] Reference Figure 1-4 The rectifier transformer includes a housing 1. Mounting seats 6 are fixedly installed on both outer sides of the housing 1. A dustproof net 7 is installed on the outer side of each mounting seat 6. Two axial flow fans 16 are symmetrically installed inside each mounting seat 6, and the airflow directions of the multiple axial flow fans 16 located on different sides are opposite. Two connecting pipes 9 are symmetrically installed on the upper and lower sides of the two inner walls of the housing 1. Each connecting pipe 9 is connected to the corresponding axial flow fan 16 through an air collecting hood 15. Multiple flow guide seats 10 are provided on the outer side of each connecting pipe 9. An activated carbon plate 20 is installed inside each mounting seat 6, and each activated carbon plate 20 is located between the dustproof net 7 and the axial flow fan 16. A regeneration component is installed inside each mounting seat 6, and the regeneration component is used to dry each activated carbon plate 20. A cleaning component is installed on the outer side of each mounting seat 6, and the cleaning component is used to clean the corresponding dustproof net 7.
[0025] It should be noted that, since the blades inside the axial flow fan 16 are symmetrically designed, when its drive source drives the blades to rotate in the opposite direction, the direction of the airflow pushed by the blades is reversed, and the air inlet side becomes the air outlet side, and vice versa. This is an existing mature technology. Through the axial flow fans 16 installed on both sides of the housing 1, the axial flow fan 16 on one side ventilates into the housing 1, and the axial flow fan 16 on the other side draws out the hot air inside the housing 1 and discharges it, thereby accelerating the air flow inside the housing 1, which facilitates the rapid cooling of the components inside the housing 1. In addition, the activated carbon plate 20 and the dustproof net 7 can effectively remove moisture and impurities in the air, avoiding any impact on the components inside the housing 1.
[0026] Furthermore, each regeneration component includes a fixing frame 17, and each fixing frame 17 is fixedly installed in the corresponding mounting base 6. Multiple heating tubes 18 are installed between the two sides of each fixing frame 17, and each heating tube 18 is located between the corresponding axial flow fan 16 and activated carbon plate 20.
[0027] When the activated carbon plate 20 on the air inlet side of the housing 1 needs to be regenerated, the drive source in the axial flow fan 16 can be reversed, so that the air inlet side of the housing 1 becomes the air outlet side, and vice versa. Then the hot air discharged from the housing 1 can initially heat up the activated carbon plate 20. At this time, the heating tube 18 is started to heat up, further promoting the heating of the activated carbon plate 20 and realizing its regeneration. The heat generated by the heating tube 18 is discharged to the outside of the housing 1, so as not to affect the normal operation of the components inside the housing 1. The water vapor generated by the regeneration of the activated carbon plate 20 can also be discharged from the housing 1, thereby realizing the regeneration of the activated carbon plate 20 and reducing the replacement frequency of the activated carbon plate 20.
[0028] Furthermore, each cleaning component includes two fixing frames 11, which are respectively installed on the upper and lower end faces of the mounting base 6. Multiple electric push rods 12 are symmetrically installed on the outer side of each fixing frame 11. The other end face of the multiple electric push rods 12 on the same side is jointly installed with a cleaning frame 13. A brush 14 is installed on the inner side of each cleaning frame 13, and each brush 14 is attached to the outer side of the corresponding dustproof net 7. When the activated carbon plate 20 on the air inlet side of the housing 1 needs to be regenerated, the air inlet side of the housing 1 is first turned into the air outlet side. Then, the hot air blown out of the housing 1 can be used to back-blow the dustproof net 7 to promote the removal of impurities clogging the dustproof net 7. After that, the brush 14 installed on the cleaning frame 13 can be driven by the electric push rod 12 to clean the dustproof net 7 back and forth.
[0029] Furthermore, each fixed frame 17 has an mounting frame 19 fixedly installed on its outer side by multiple bolts, and each activated carbon plate 20 is installed in the corresponding mounting frame 19, and the dustproof net 7 is also installed with bolts.
[0030] Furthermore, the multiple flow guides 10 connected to the outside of each connecting pipe 9 are arranged in a ring at equal intervals. Through the flow guides 10, air can be blown into the housing 1 from multiple directions. Heat dissipation fins 3 are installed on both outer sides of the housing 1.
[0031] Furthermore, two mounting plates 2 are symmetrically installed on the bottom surface of the housing 1, and multiple low-pressure bushings 4 and high-pressure bushings 5 are respectively installed on the top surface of the housing 1. A winding device 8 is provided inside the housing 1.
[0032] In practical use, the working principle of this utility model is as follows:
[0033] In this utility model, when the device is used, firstly, the axial flow fans 16 on both sides of the housing 1 are started. One side of the axial flow fan 16 rotates in the forward direction to ventilate into the housing 1, while the other side rotates in the reverse direction to draw out the hot air from the housing 1. The outside air first passes through the dust filter 7 to filter impurities, then passes through the activated carbon plate 20 to remove moisture, and then enters the connecting pipe 9 through the air collector hood 15. Finally, it is sent into the housing 1 from multiple directions by the guide seat 10 to accelerate the air flow and achieve rapid cooling.
[0034] When the activated carbon plate 20 needs to be regenerated, the axial flow fan 16 on the corresponding side is reversed to become the air outlet side, and the axial flow fan 16 on the other side is reversed to become the air inlet side. The hot air discharged from the housing 1 initially heats the activated carbon plate 20, and at the same time the heating tube 18 is activated to further heat the activated carbon plate 20. The water vapor is discharged with the airflow to complete the regeneration, and the heat does not affect the components inside the housing 1.
[0035] Meanwhile, during the regeneration of the activated carbon plate 20, hot air from the outlet side is used to back-blown the dust filter 7, and the brush 14 on the cleaning rack 13 is driven by the electric push rod 12 to clean back and forth, ensuring smooth ventilation. In addition, the heat dissipation fins 3 assist in heat dissipation, the mounting plate 2 facilitates the fixing of the device, and the low-voltage bushing 4 and the high-voltage bushing 5 ensure the circuit connection. All components work together to achieve efficient and stable operation of the transformer.
[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
