[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformers). According to their application, they can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impulse transformers, instrument transformers, electronic transformers, reactors, instrument transformers, etc.).

[0003] Currently, existing outdoor power transmission transformers are prone to overheating after prolonged operation, which could lead to transformer failure. Therefore, a new design has been developed to address this issue. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an outdoor power transmission transformer that facilitates heat dissipation, comprising a transformer assembly, wherein a cleaning device is fixedly connected to the inner side of the transformer assembly; The transformer unit includes a transformer housing. Airflow enters the interior of the transformer housing through a ventilation housing, thereby achieving ventilation and heat dissipation, accelerating heat exchange, maintaining a safe temperature, reducing the risk of localized overheating, and minimizing the effects of humidity and condensation. A ventilation housing is fixedly connected to one side of the transformer housing, employing a slanted air intake structure to reduce the entry of some impurities. A filter plate is fixedly connected to the inside of the ventilation housing near the inner wall of the transformer housing. The filter plate filters impurities, intercepting them and causing them to adhere to the surface of the components, thus reducing their impact on the internal structure and preventing interference with heat dissipation. A square housing is fixedly connected to the outside of the ventilation housing near the filter plate. When natural ventilation is insufficient for transformer cooling, a fan generates airflow to expel the hot air from inside the transformer housing, achieving ventilation and heat dissipation, thereby improving the equipment's heat dissipation efficiency and preventing excessively high internal temperatures. To prevent damage to some electronic components, a fan is fixedly connected to the side of the square housing away from the filter plate. After the airflow enters the ventilation housing, it flows towards the fan and comes into contact with the adsorption mechanism. The adsorption mechanism absorbs moisture in the air, thereby reducing the impact of moisture on electronic components, keeping the inside of the equipment dry, reducing the probability of equipment failure, and extending the service life of the equipment. An adsorption mechanism is fixedly connected to the outside of the fan, and a cleaning device is set on the inside of the square housing. The cleaning device slides back and forth to rub the surface of the filter plate, thereby cleaning impurities, reducing the amount of impurities adhering to the surface of the components, avoiding excessive impurities from clogging the holes, preventing the airflow effect from being affected, and maintaining the normal operation of the equipment. A drain mechanism is fixedly connected to the bottom of the square housing. The cleaned impurities fall to the bottom of the square housing, which facilitates subsequent processing or enters the drain mechanism. The drain mechanism plays a role in draining water, preventing water from entering the equipment and causing damage.

[0005] Preferably, a sealing mechanism is fixedly connected to the inner wall of the square housing near the fan. During heavy rain, the sealing mechanism blocks the fan, preventing external water from entering, protecting the insulation system, preventing leakage or short circuits, preventing corrosion of metal parts, extending equipment life, preventing damage to core components, ensuring stable function, and directing the blocked water flow towards the drainage mechanism, thus facilitating water flow guidance and reducing water ingress. An anti-collision mechanism is fixedly connected to the outer side of the transformer housing near the ventilation housing. This mechanism provides some protection, reducing external impacts, protecting the transformer structure, preventing physical damage, protecting vulnerable parts from impacts, reducing the impact of vibration on internal components, ensuring stable electrical function, preventing equipment shutdown, protecting the internal insulation system from damage, preventing failures of precision components such as tap changers and transformers, reducing the risk of secondary accidents, and ensuring the safety of personnel and the power grid.

[0006] Preferably, the sealing mechanism includes a first slide rail, one side of which is fixedly connected to the inner wall of the square housing. A first slider is slidably connected to the outer side of the first slide rail, and a sealing plate is fixedly connected to the outer side of the first slider. The first slider drives the sealing plate to slide on the first slide rail, thereby controlling the opening and closing of the sealing plate. When the sealing plate is separated, it facilitates gas flow, thus facilitating ventilation of the components. When the sealing plate is closed, it blocks water from entering, thereby preventing external water from entering, protecting the insulation system, preventing leakage or short circuits, preventing corrosion of metal components, extending equipment life, preventing damage to core components, and ensuring stable function.

[0007] Preferably, the adsorption mechanism includes a grid cover, with a connecting shaft fixedly connected to the inner wall of the grid cover away from the fan. A rotating column is rotatably connected to the outer side of the connecting shaft. The airflow acts on the surface of the adsorption plate, causing the adsorption plate to rotate, thereby achieving dynamic filtration and purification, efficiently intercepting impurities in the airflow, and improving filtration and adsorption efficiency. The adsorption plate is fixedly connected to the outer side of the rotating column, and the airflow comes into contact with the adsorption plate during the flow, thereby adsorbing moisture in the airflow, reducing the amount of moisture entering the equipment, and providing a certain degree of protection for the internal electronic components. This reduces the impact of moisture on the electronic components, keeps the inside of the equipment dry, reduces the probability of equipment failure, and thus extends the service life of the equipment.

[0008] Preferably, the discharge mechanism includes a discharge housing, the top of which is fixedly connected to the bottom of a square housing. A trapezoidal groove is formed inside the discharge housing, and a feed inlet is formed at the top of the discharge housing. A discharge valve is fixedly connected to one side of the discharge housing. Water or impurities enter the discharge housing through the feed inlet, and the trapezoidal groove guides the impurities and water flow, reducing water stagnation. The discharge valve controls liquid discharge and prevents external water or impurities from entering, thus protecting the equipment.

[0009] Preferably, the anti-collision mechanism includes a second slide rail, one side of which is fixedly connected to the outer side of the transformer housing. An anti-collision frame is slidably connected to the outer side of the second slide rail away from the transformer housing. An anti-collision shell is fixedly connected to the inner side of the anti-collision frame. A spring strip is fixedly connected to the inner wall of the anti-collision shell. A sliding frame is fixedly connected to the outer side of the spring strip away from the filter plate. When external pressure impacts the receiving plate, the receiving plate drives the sliding frame to compress and contract the spring strip inside the anti-collision shell, thereby providing shock absorption and buffering, reducing external impacts on the equipment, protecting the transformer structure, preventing physical damage, and protecting vulnerable components from impact. To reduce the impact of vibration on internal components, ensure stable electrical functions, prevent equipment downtime, protect the internal insulation system from damage, prevent failures of precision components such as tap changers and transformers, reduce the risk of secondary accidents, and ensure the safety of personnel and the power grid, the outer side of the sliding frame is slidably connected to the inner side of the anti-collision shell. A support plate is fixedly connected to the outer side of the sliding frame away from the spring strip, and a silicone block is fixedly connected to the outer side of the support plate. The silicone block increases the wear resistance of the components, provides a certain degree of protection, reduces the wear of the components caused by external impacts, thereby extending the service life of the components, and the silicone material also provides a certain cushioning effect, further protecting the components.

[0010] Preferably, the cleaning device includes a third slide rail, and a second slider is slidably connected to the outer side of the third slide rail. The second slider drives the friction column to slide back and forth on the third slide rail, so that the friction column rubs against the surface of the filter plate, thereby cleaning the impurities on the surface of the component, reducing the amount of impurities adhering to the surface of the component, avoiding excessive impurities from clogging the holes, preventing the airflow effect from being affected, and maintaining the normal operation of the equipment. A clamping mechanism is fixedly connected to the side of the second slider away from the third slide rail. The clamping mechanism clamps the support shaft, thereby facilitating disassembly and installation and reducing the difficulty of equipment operation. A support shaft is provided between the opposite surfaces of the clamping mechanism, and a friction column is rotatably connected to the outer side of the support shaft.

[0011] Preferably, an annular grinding block is fixedly connected to the outer side of the friction column. The annular grinding block is made of plastic to increase the wear resistance of the component, reduce rigid collisions between components, reduce wear between components, and thus extend the service life of the component. The outer side of the annular grinding block is provided with a block groove. By providing the block groove, the surface texture of the component is increased, thereby further improving the friction effect of the component and improving the cleaning efficiency of the component.

[0012] Preferably, the clamping mechanism includes a clamping frame, with a square bracket slidably connected to the outer side of the clamping frame. A soft rubber block is fixedly connected to one side of the outer side of the square bracket. The soft rubber block is subjected to the reaction force of the support shaft, causing the soft rubber block to drive the square bracket to compress the square spring. The soft rubber block deforms with the shape of the support shaft, thereby facilitating the fit of the component against the surface of the support shaft, reducing the movement space of the component, and further improving the clamping effect of the component. A square spring is sleeved on the outer side of the square bracket near the soft rubber block, and the square spring supports the soft rubber block, thereby achieving the function of clamping the component and reducing mechanical wear between components during the clamping process, thereby extending the service life of the component.

[0013] This invention provides an outdoor power transmission transformer that facilitates heat dissipation. It has the following beneficial effects: I. This outdoor power transmission transformer, designed for efficient heat dissipation, utilizes a transformer assembly design where airflow enters the transformer housing from the ventilated casing, facilitating ventilation and heat dissipation. This accelerates heat exchange, maintains a safe temperature, reduces the risk of localized overheating, and minimizes the impact of humidity and condensation. The ventilated casing employs a slanted air intake structure to reduce the entry of impurities. Filter plates filter impurities, intercepting them and adhering them to component surfaces, thus reducing their impact on the internal components and preventing interference with heat dissipation. After entering the ventilated casing, the airflow flows towards the fan side, contacting the adsorption mechanism. This mechanism absorbs moisture from the air, reducing its impact on electronic components, keeping the internal components dry, lowering the probability of equipment failure, and extending the equipment's lifespan. Furthermore, when natural ventilation is insufficient for transformer cooling, the fan generates airflow to expel the hot air from the transformer housing, further improving heat dissipation efficiency and preventing overheating that could damage electronic components. A cleaning device is installed inside the square casing, which reciprocates to clean the surface of the filter plates. Friction is used to clean impurities, reducing their adhesion to component surfaces and preventing excessive impurities from clogging pores, thus ensuring proper airflow and normal equipment operation. Cleaned impurities fall to the bottom of the square casing for subsequent processing or into the drainage mechanism, which discharges water to prevent it from entering the equipment and causing damage. During heavy rain, the sealing mechanism shields the fan, preventing external water from entering, protecting the insulation system, preventing leakage or short circuits, and preventing corrosion of metal components. "Corrosion" extends equipment life, avoids "damage to core components", ensures stable function, and blocks water flow to the discharge mechanism side, thereby facilitating water flow guidance and reducing water ingress. Secondly, the anti-collision mechanism provides a certain degree of protection for the equipment, reducing external impacts on the equipment, protecting the transformer body structure, avoiding physical damage, protecting vulnerable parts from impact, reducing the impact of vibration on internal components, ensuring stable electrical function, avoiding equipment shutdown, protecting the internal insulation system from damage, avoiding failure of precision components such as tap changers and transformers, reducing the risk of secondary accidents, and ensuring the safety of personnel and the power grid.

[0014] Second, this outdoor power transmission transformer, which facilitates heat dissipation, employs a closed mechanism design. The first slider drives the sealing plate to slide on the first slide rail, thereby controlling the opening and closing of the sealing plate. When the sealing plate is separated, it facilitates gas flow, thus enabling ventilation of the components. When the sealing plate is closed, it blocks water flow, thereby preventing external water from entering, protecting the insulation system, preventing leakage or short circuits, preventing corrosion of metal components, extending equipment life, preventing damage to core components, and ensuring stable function.

[0015] Third, this outdoor power transmission transformer, which facilitates heat dissipation, uses an adsorption mechanism design. During the airflow process, it comes into contact with the adsorption plate, thereby adsorbing moisture in the airflow. This reduces the amount of moisture entering the equipment, providing a certain degree of protection for the internal electronic components. It also reduces the impact of moisture on the electronic components, keeps the equipment dry, lowers the probability of equipment failure, and extends the service life of the equipment. At the same time, the airflow acts on the surface of the adsorption plate, causing the adsorption plate to rotate, thereby achieving dynamic filtration and purification, efficiently intercepting impurities in the airflow, and improving filtration and adsorption efficiency.

[0016] Fourth, this outdoor power transmission transformer, designed for easy heat dissipation, incorporates an anti-collision mechanism. When external pressure impacts the receiving plate, the receiving plate drives the sliding frame to compress and contract the spring strip inside the anti-collision housing, thus providing shock absorption and buffering. This reduces external impacts on the equipment, protects the transformer's structure from physical damage, protects vulnerable components from impact, reduces the impact of vibration on internal components, ensures stable electrical functions, prevents equipment downtime, protects the internal insulation system from damage, prevents failures of precision components such as tap changers and transformers, reduces the risk of secondary accidents, and ensures the safety of personnel and the power grid. Furthermore, the silicone blocks increase the wear resistance of components, providing a certain degree of protection and reducing wear from external impacts, thereby extending the service life of the components. The silicone material also provides a certain buffering effect, further protecting the components.

[0017] V. This outdoor power transmission transformer, designed for easy heat dissipation, utilizes a cleaning device. A second slider drives a friction column to reciprocate along a third slide rail, allowing the friction column to rub against the filter plate surface. This effectively cleans impurities from the component surface, reducing their adhesion and preventing pore blockage due to excessive impurities. This prevents impurities from affecting airflow and ensures normal equipment operation. A clamping mechanism holds the support shaft, facilitating disassembly and installation, thus reducing operational difficulty. The annular grinding block is made of plastic to increase wear resistance, reduce rigid collisions between components, and minimize wear, extending component lifespan. Furthermore, grooves on the block surface enhance texture, further improving friction and cleaning efficiency. Attached Figure Description

This accelerates heat exchange, maintains a safe temperature, reduces the risk of localized overheating, and minimizes the impact of humidity and condensation. The ventilation housing 12 employs a slanted air inlet structure to reduce the entry of some impurities. The filter plate 13 filters impurities, intercepting them and causing them to adhere to the surface of components, thereby reducing their impact on the internal structure and preventing interference with heat dissipation.

The first slider 162 drives the sealing plate 163 to slide on the first slide rail 161, thereby controlling the opening and closing of the sealing plate 163. When the sealing plate 163 is open, it facilitates gas flow, thus facilitating ventilation of the components.

At the same time, the airflow acts on the surface of the adsorption plate 174, causing the adsorption plate 174 to rotate, thereby achieving dynamic filtration and purification, efficiently intercepting impurities in the airflow, and improving filtration and adsorption efficiency.

[0025] The second embodiment is based on the first embodiment; please refer to [link / reference].
