Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer electrical ventilation technology, and in particular to a transformer electrical ventilation device for electrical engineering. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers are among the most common components in electrical appliances. However, transformers generate high temperatures during prolonged operation, requiring cooling to continue working. Therefore, ventilation devices are used for cooling.
[0003] A search revealed an electrical ventilation device for transformers used in electrical engineering (authorization announcement number: CN 220155313 U), which "includes a housing, with a transformer body housed within the housing's interior. Ventilation slots are provided on both sides of the top of the housing, and several heat dissipation slots are provided on the left side of the middle section of the housing. Two sliding grooves are equidistantly located on the left side of the housing, and a filter screen is provided on the left side of the housing. Two sliders are equidistantly located on the right side of the filter screen, and a connecting ring is fixedly installed on the front of the filter screen. The combined use of the housing, transformer body, ventilation slots, frame, ventilation fan, protective net, door, and handle not only allows for the replacement of internal air, improving the efficiency of the transformer body within the housing, but also prevents external dust from entering the housing through the ventilation slots during ventilation, thus preventing damage to the transformer body and affecting normal operation. Furthermore, it facilitates opening the housing for easy maintenance of the transformer body."
[0004] Based on the aforementioned technologies, the applicant believes that although the above technologies can dissipate heat from the enclosure through the heat dissipation windows, dust will adhere to the heat dissipation windows after long-term use, requiring disassembly and cleaning, which is inconvenient and cannot achieve automatic cleaning. In response to the above problems, we have introduced an electrical ventilation device for transformers in electrical engineering. Utility Model Content

[0030] The electrical ventilation device for transformers disclosed in this utility model is mainly used in the scenario of electrical ventilation of transformers.
[0031] Reference Figures 1-6An electrical ventilation device for transformers used in electrical engineering includes a housing 1, inside which a transformer body 2 is installed. Heat dissipation slots 3 are equidistantly spaced on both sides of the inner wall of the housing 1. The housing 1 also includes a ventilation mechanism comprising two cleaning components and an auxiliary heat dissipation component, which work together. Each cleaning component includes a cleaning motor 41, which is fixedly connected to the outside of the housing 1. A rectangular array of fixing plates 42 are fixedly connected to one side of the inner wall of the housing 1, and sliding columns 43 are fixedly connected between two fixing plates 42 on the same side. Sliding blocks 44 are slidably connected to the outer sides of the two sliding columns 43. A lifting plate 45 is fixedly connected between the two sliding blocks 44. A cleaning brush 46 is fixedly connected to the side of the lifting plate 45 near the heat dissipation slot 3. The output end of the cleaning motor 41 extends into the interior of the housing 1 and is fixedly connected to a rotating plate 49. Connecting rods 47 are symmetrically fixedly connected to the outer sides of the lifting plate 45. A sliding rod 48 is fixedly connected between the two connecting rods 47. A sliding sleeve 410 is slidably connected to the outer side of the sliding rod 48. A connecting shaft 411 is rotatably connected to the outer side of the sliding sleeve 410. The connecting shaft 411 and the rotating plate 49 are fixedly connected. The auxiliary heat dissipation assembly includes ventilation slots 5, which are equidistantly located at the bottom of the inner wall of the housing 1. A support frame 6 is fixedly connected to the bottom of the housing 1. Universal wheels 7 are symmetrically provided on both sides of the bottom of the support frame 6. The universal wheels 7 have a locking function. Reinforcing plates 8 are symmetrically fixedly connected to both sides of the support frame 6.
[0032] In this embodiment: When the transformer body 2 is working, it generates heat, which is dissipated by natural convection through the heat dissipation slots 3 and ventilation slots 5. After long-term ventilation and heat dissipation, when dust adheres to the inner and outer walls of the heat dissipation slots 3, the outer wall can be wiped clean. When cleaning the inner wall, the cleaning motor 41 starts and drives the rotating plate 49 to rotate. Through the connecting shaft 411, it pushes the sliding sleeve 410 to move along the sliding rod 48, so that the lifting plate 45 slides up and down along the sliding column 43. Through the set ventilation mechanism, the inner wall of the heat dissipation slots 3 can be cleaned quickly, avoiding dust from adhering to the inner wall of the heat dissipation slots 3. The cleaning brush 46 drives the cleaning brush 46 to clean the dust in the heat dissipation slots 3, ensuring smooth ventilation. The structure is simple and highly practical.
[0033] The above technical solution considers the problem that while heat dissipation is achieved through ventilation windows, dust accumulates on these windows after prolonged use, requiring disassembly and cleaning, which is inconvenient and prevents automatic cleaning. To address this issue, the specific operation is as follows:
[0034] Reference Figures 1-6In a preferred embodiment, the top of the transformer body 2 is provided with a connection terminal 13 for wiring, and the top of the mounting box 1 has wiring holes 11 arranged in a rectangular array. Protective covers 9 are fixedly connected to the outer sides of both cleaning motors 41, and ventilation slots 10 are equidistantly provided inside both protective covers 9. An observation window 12, made of transparent material, is provided on the front of the mounting box 1. A controller 14 is fixedly connected to the front of the mounting box 1, and both cleaning motors 41 are electrically connected to the controller 14.
[0035] In this embodiment, the wiring hole 11 and the connection terminal 13 facilitate wiring operations on the transformer body 2 while keeping the interior of the housing 1 tidy, preventing messy wiring from affecting heat dissipation and maintenance. The protective cover 9 protects the cleaning motor 41 from external environmental influences, and the ventilation slot 10 ensures heat dissipation for the motor, extending its service life. The observation window 12 is made of transparent material, facilitating real-time monitoring of the operating status of the transformer body 2 without frequent opening of the housing for inspection. The controller 14 centrally controls the cleaning motor 41, realizing automated cleaning operations, improving maintenance efficiency, and reducing manual intervention.
[0036] Working principle: When the transformer body 2 is working, it generates heat, which is dissipated by natural convection through the heat dissipation slots 3 and ventilation slots 5. After long-term ventilation and heat dissipation, when dust adheres to the inner and outer walls of the heat dissipation slots 3, the outer wall can be wiped clean. When cleaning the inner wall, the cleaning motor 41 starts and drives the rotating plate 49 to rotate. Through the connecting shaft 411, it pushes the sliding sleeve 410 to move along the sliding rod 48, so that the lifting plate 45 slides up and down along the sliding column 43, driving the cleaning brush 46 to clean the dust in the heat dissipation slots 3, ensuring smooth ventilation. The universal wheel 7 facilitates the movement of the device. The observation window 12 and the controller 14 provide status monitoring and automatic control functions, respectively. The overall structure is stable and easy to maintain.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
