Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to an oil-immersed transformer. Background Art

[0002] In modern power systems, oil-immersed transformers, as core equipment, undertake the key tasks of voltage conversion and power transmission and distribution. The reliability and stability of their operation are directly related to the safe and efficient operation of the entire power system.

[0003] As a key heat dissipation component of oil-immersed transformers, heat dissipation fins play an important role in the heat dissipation process of transformers by increasing the heat dissipation area and strengthening convective heat transfer. Reasonably designed heat dissipation fins can significantly improve the heat dissipation efficiency of transformers, reduce the oil temperature, and thus enhance the overload capacity and operation reliability of transformers. With the development of power systems towards high-capacity and compact directions, the power density of transformers is continuously increasing, and the generated heat is also correspondingly increasing. This poses higher requirements for the heat dissipation performance of heat dissipation fins.

[0004] Oil-immersed transformers are usually used in factories to control the power systems of entire workshops. Due to the relatively harsh operating environments in factories, a large amount of dust usually adheres to the radiator fins of transformers. For this reason, a cleaning system is usually provided at the heat dissipation fins to clean the dust adhering to the heat dissipation fins. Common cleaning methods usually include pneumatic cleaning or brush cleaning.

[0005] However, when the pneumatic cleaning system cleans dust, it will blow the dust adhering to the heat dissipation fins in all directions. If the dispersed dust adheres to the surfaces of insulating components such as windings, bushings, and insulators of the transformer, it will form a conductive path or reduce the dielectric strength of the insulation; during brush cleaning, although the dust can be centrally cleaned to avoid the dust scattering everywhere, the hard bristles of the brush will scratch the anti-rust coating on the surface of the fins and accelerate metal corrosion.

[0006] For this, we propose an oil-immersed transformer. Summary of the Invention

[0020] The present invention has the following beneficial effects: 1. The oil-immersed transformer, through the design of the dust suppression component, effectively solves the problem of dust scattering everywhere during pneumatic cleaning. When the connecting plate slides, the hydraulic oil system drives the piston plate to move smoothly in the air pressure groove, so that the vertical air outlet block sprays air downward through the air outlet nozzle, applying a downward wind force to the dust scattered by the pneumatic cleaning equipment, and prompting the dust to concentrate and converge downward. This design can prevent the dust from adhering to the surfaces of insulating components such as transformer windings, bushings, and insulators after scattering, reducing the risk of forming a conductive path or reducing the dielectric strength of the insulating medium, and significantly improving the safety and reliability of the transformer operation. At the same time, the hydraulic oil system is used to transmit power, ensuring the smooth movement of the piston plate, making the dust suppression effect stable and reliable, without the need for an additional power source, with a simple structure and low energy consumption, being able to continuously and effectively control the dust scattering direction, creating a clean and safe operating environment for the transformer, reducing the potential trouble caused by dust problems, and extending the service life of the transformer.

[0021] 2. The oil-immersed transformer, with the setting of the swinging component, further optimizes the dust control effect. When the hydraulic oil slider moves, the driving component makes the plug rod drive the connecting rod to swing, and then the air outlet nozzle swings and jets air from both sides to the middle. This design can make the blown-off dust gather from both sides to the middle, effectively restricting the scattering range of the dust, enhancing the dust gathering effect, facilitating the subsequent centralized collection and treatment of the dust, reducing the cleaning difficulty, improving the cleaning efficiency, realizing the swinging function by using the linkage of the hydraulic system, saving energy, having a compact structure and good linkage, while controlling the dust direction, improving the overall cleaning efficiency and convenience, making the dust management more centralized and orderly, and reducing the secondary pollution problem caused by dust diffusion.

[0022] 3. The oil-immersed transformer, through the water mist component and the intermittent control component, further improves the comprehensive effect of dust control. The water mist component sprays water in a mist form on the dust surface through the water mist nozzle, increasing the self-weight of the dust particles, making them easier to settle and avoiding floating and spreading. The water mist can also penetrate into the narrow gaps of the heat dissipation fins, wash away the deep accumulated dust, dissolve water-soluble pollutants such as salts and oil stains, and the cleaning effect is better than that of simple dry blowing. At the same time, the evaporation of water can take away part of the heat, playing an auxiliary cooling role in high-temperature seasons. The intermittent control component realizes the intermittent spraying of the water mist by controlling the valve to open intermittently, which not only avoids the formation of a continuous conductive film on the surface of the heat dissipation fins, but also saves water resources and reduces the amount of sewage generated. The sprayed sewage can be centrally collected and treated, which is environmentally friendly and efficient. This design can effectively suppress dust while taking into account the cleaning depth, safety and economy, is applicable to various complex environments, improves the comprehensiveness and reliability of transformer maintenance, and provides a better guarantee for the stable operation of the transformer.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1. This embodiment aims to facilitate the solution of the problem that when the pneumatic cleaning system cleans dust, the dust attached to the heat dissipation fins will be blown around. Please refer to Figures 1 to 11 , an oil-immersed transformer, including a transformer body and a heat dissipation component 1. The transformer body includes a housing, an iron core, windings, an insulation system, and a cooling device. The iron core is fixed inside the housing and is laminated by silicon steel sheets to form a closed magnetic circuit, responsible for conducting the magnetic field and reducing eddy current losses. The windings are wound around the iron core and are wound by copper or aluminum wires to achieve energy transfer through electromagnetic induction. The insulation system is arranged between the iron core and the windings and includes insulating oil, paper, and resin, used to isolate the windings from the iron core to prevent short circuits. The insulating oil has both heat dissipation and insulation functions. The cooling device is oil-immersed and filled inside the housing, and the heat is dissipated through the heat dissipation component 1; Specifically, the heat dissipation component 1 includes heat dissipation fin plates 11 and vertical plates 12. The heat dissipation fin plates 11 and the vertical plates 12 are fixed on the side walls of the housing of the transformer body. A connecting plate 15 is provided on the side wall of the vertical plate 12, and a pneumatic cleaning device 16 and a dust suppression component 2 are provided on the side wall of the connecting plate 15.

[0027] A T-shaped track 13 is opened on the side wall of the vertical plate 12, and a T-shaped slider 14 is slidably connected in the T-shaped track 13. A connecting plate 15 is fixedly connected to the side wall of the T-shaped slider 14, and the pneumatic cleaning device 16 is arranged at the gap of the heat dissipation fin plates 11.

[0028] The sliding of the T-shaped slider 14 in the T-shaped track 13 is controlled by a motor and a lead screw (the control of the slider sliding in the chute by the motor and lead screw is a prior art. Similarly, the cleaning of the side wall of the heat dissipation fin plates 11 by the pneumatic cleaning device 16 is also a prior art, and this solution will not be described in detail).

[0029] The dust suppression component 2 is used to control the dust raising direction generated by the pneumatic cleaning device 16. The dust suppression component 2 is located above the pneumatic cleaning device 16. The dust suppression component 2 includes a pneumatic control plate 21, and a vertical air outlet block 24 is provided at the bottom of the pneumatic control plate 21, and a swing component 3 is installed in the vertical air outlet block 24.

[0030] The pneumatic control plate 21 is fixedly connected above the pneumatic cleaning device 16. An air pressure groove 22 is opened in the pneumatic control plate 21, and a piston plate 23 is slidably connected in the air pressure groove 22. The top of the pneumatic control plate 21 is communicated with a hydraulic oil pipeline 25.

[0031] A hydraulic oil chamber 26 is provided in the connecting plate 15. One side of the hydraulic oil chamber 26 is communicated with a hydraulic oil pipeline 25. A hydraulic oil slider 27 is slidably connected in the hydraulic oil chamber 26. One side of the hydraulic oil slider 27 is fixedly connected with a driving rod 28. The driving rod 28 is slidably connected in a driving track groove 29 which is provided on the side wall of the vertical plate 12.

[0032] In the prior art, the cleaning of the gaps between the heat dissipation fins 11 by the pneumatic cleaning device 16 usually uses a DC air duct to clean the side plates of the heat dissipation fins 11. In this cleaning method, the dust on the side walls of the heat dissipation fins 11 drifts everywhere. If the drifted dust adheres to the surfaces of insulating components such as the windings, bushings, and insulators of the transformer, it will form a conductive path or reduce the dielectric strength of the insulating medium. Therefore, through the setting of the dust suppression component 2, the drifted dust can be blown downward to avoid the situation that the drifted dust adheres to the surfaces of insulating components such as the windings, bushings, and insulators of the transformer, which will form a conductive path or reduce the dielectric strength.

[0033] When the connecting plate 15 slides with the T-shaped slider 14, through the cooperation of the driving rod 28 and the driving track groove 29, the hydraulic oil slider 27 in the hydraulic oil chamber 26 generates a piston motion. Since the hydraulic oil chamber 26 is communicated with the space above the pneumatic control plate 21 through the hydraulic oil pipeline 25, the piston plate 23 is driven to perform a piston motion in the air pressure groove 22. Using a hydraulic oil system as the power transmission component can ensure the smooth sliding of the piston plate 23 in the air pressure groove 22. Due to the piston motion of the piston plate 23 in the air pressure groove 22 and the pneumatic control plate 21 being arranged above the pneumatic cleaning device 16, when the pneumatic cleaning device 16 blows off the dust on the side walls of the heat dissipation fins 11, through the setting of the vertical air outlet block 24 and the air outlet nozzle 35, a downward wind force is applied to the scattered dust, so that the dust can be further gathered downward to avoid the situation that the drifted dust adheres to the surfaces of insulating components such as the windings, bushings, and insulators of the transformer, which will form a conductive path or reduce the dielectric strength.

[0034] Embodiment 2, based on Embodiment 1, please refer to Figures 1 to 11 , specifically, the swinging assembly 3 is used to control the jetting trajectory of the air outlet nozzle 35. The swinging assembly 3 includes a swinging groove 31 opened at the bottom of the vertical air outlet block 24. A swinging hollow block 32 is rotatably connected in the swinging groove 31. The air outlet nozzle 35 is installed at the bottom of the swinging hollow block 32.

[0035] A swinging shaft 33 is fixedly connected to the side wall of the swinging hollow block 32. The other end of the swinging shaft 33 is fixedly connected with a connecting rod 34. The connecting rod 34 is used to connect adjacent swinging hollow blocks 32.

[0036] The swinging of the swinging shaft 33 is controlled by the driving assembly 4. The driving assembly 4 includes a driving groove 45 formed in the connecting plate 15. A driving cross-shaped slide plate 46 is slidably connected in the driving groove 45. One side of the driving cross-shaped slide plate 46 is fixedly connected with a plugging rod 43. The driving cross-shaped slide plate 46 is connected to the driving groove 45 through a first spring 47.

[0037] An empty groove 41 and a spiral groove 42 are formed in the connecting rod 34. The plugging rod 43 is inserted into the empty groove 41. A spiral slider 44 is slidably connected in the spiral groove 42. The spiral slider 44 is fixedly connected to the side wall of the plugging rod 43.

[0038] The design of the swinging assembly 3 enables the air outlet nozzle 35 to swing from both sides to the inside when jetting air, thereby further restricting the drifting direction of dust.

[0039] When the hydraulic oil slider 27 slides leftward in the hydraulic oil chamber 26, the hydraulic oil slider 27 abuts against the bottom of the driving cross-shaped slide plate 46, thereby driving the driving cross-shaped slide plate 46 and the plugging rod 43 fixedly connected thereto to slide leftward synchronously. Since the plugging rod 43 is inserted into the connecting rod 34 and a spiral slider 44 and a spiral groove 42 are provided between the plugging rod 43 and the connecting rod 34, as the plugging rod 43 moves leftward, the connecting rod 34 is synchronously driven to swing (the swinging amplitude of the air outlet nozzle 35 is controlled by the number of turns of the spiral groove 42 and is set by those skilled in the art according to actual needs). Through the rotation of the connecting rod 34, the swinging shaft 33 and the swinging hollow block 32 fixedly connected thereto are driven to swing synchronously; The purpose is to enable the air outlet nozzle 35 to swing from both sides to the middle while discharging air, so that the dust blown off by the pneumatic cleaning device 16 gathers from both sides to the middle, thereby facilitating the subsequent collection of dust.

[0040] In some embodiments, in order to facilitate the subsequent collection of dust, a water tank can be provided below the transformer. Driven by the dust suppression assembly 2, the dust is blown into the water tank to facilitate the subsequent collection of dust.

[0041] Embodiment 3, based on Embodiment 2, please refer to Figures 1 to 11 , specifically, a water mist assembly 5 is provided in the pneumatic control board 21. The water mist assembly 5 is used to increase the self-weight of dust particles. The water mist assembly 5 includes a water inlet channel 51 and a water collecting tank 52 formed in the connecting plate 15. The water collecting tank 52 communicates with a branch groove 53. The branch groove 53 is provided in the pneumatic control board 21. The branch groove 53 communicates with a water mist nozzle 54. The water mist nozzle 54 is installed at the bottom of the pneumatic control board 21.

[0042] An intermittent control component 6 connected to the control branch groove 53 is provided in the pneumatic cleaning equipment 16, and the intermittent control component 6 includes a valve 61 arranged in the branch groove 53, a control rod 62 is provided on one side of the valve 61, and a resistance rod 63 is abutted on one side of the control rod 62, and the resistance rod 63 is slidably connected in a limiting slide groove 64, and the limiting slide groove 64 is opened in the connecting plate 15, and an eccentric rod 67 is provided on one side of the resistance rod 63, and a control groove 65 is opened in the connecting plate 15, and a gear 66 and a one-way drive rod 68 are provided in the control groove 65, and the side wall of the gear 66 is fixedly connected with the eccentric rod 67, and a one-way component 69 is provided in the one-way drive rod 68, and a No. 2 spring 610 is provided between the one-way drive rod 68 and the control groove 65.

[0043] The one-way component 69 includes a one-way groove 691 provided in the one-way driving rod 68 , a fixed shaft 692 is fixedly connected in the one-way groove 691 , a side wall of the fixed shaft 692 is rotatably connected to a one-way tooth block 694 via a torsion spring 693 , and the one-way tooth block 694 is meshed with the gear 66 .

[0044] The design of the water mist component 5 can increase the weight of the dust, making it easier to control and thus preventing the dust from flying around. The water mist component 5 is connected to the water supply device through the water inlet channel 51, so that the water supply device provides water source and water pressure to the water mist nozzle 54 through the water collecting tank 52 and the branch tank 53. The water is sprayed on the dust surface in the form of mist through the water mist nozzle 54, so that the weight of the dust is increased, thereby further preventing the dust from flying around. At the same time, the water mist can penetrate into the narrow gap of the heat sink fins under pressure, and wash away the deep dust that is difficult to reach with the air gun. If the dust contains water-soluble substances such as salts and oil, the water mist can directly dissolve or dilute the pollutants, and the cleaning effect is better than simple dry blowing. After the water mist is sprayed onto the surface of the heat sink fins, the evaporation of water can take away part of the heat, temporarily reducing the fin temperature while cleaning, which is especially suitable for auxiliary cooling during maintenance in high temperature seasons; It is worth mentioning that the water supply equipment is a combination of a water tank and a water pump. The water source of the water tank can be replenished by the staff during regular inspections, which will not be elaborated in detail here; The design of the intermittent control component 6 controls the spraying frequency of the water mist. When the hydraulic oil slider 27 slides to the left in the hydraulic oil tank 26, the hydraulic oil slider 27 contacts the bottom of the one-way driving rod 68 to drive the one-way driving rod 68 to slide upward, thereby causing the one-way component 69 in the one-way driving rod 68 to mesh with the gear 66, driving the gear 66 to rotate. Through the rotation of the gear 66, the eccentric rod 67 installed on the side wall of the gear 66 is driven to contact the resistance rod 63, and the resistance rod 63 is driven to move upward. Through the movement of the resistance rod 63, the control rod 62 can be driven to open the valve 61, thereby driving the liquid to flow, thereby realizing the intermittent spraying of the water mist nozzle 54. This intermittent water spraying design can make the water mist evaporate or drip in a very short time, thereby avoiding the formation of a continuous conductive film on the surface of the heat sink fins, and the intermittent water spraying design can save water resources. At the same time, the amount of sewage generated by short-term water spraying is small, and the sprayed water will fall into the water tank arranged under the heat sink 11 for centralized collection and treatment.
