Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with a multi-functional cooling system. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core. Its working principle is based on Faraday's law of electromagnetic induction. When an alternating current is passed through the primary coil, an alternating magnetic flux is generated in the iron core, which induces an electromotive force in the secondary coil. Transformers can be classified according to their uses, such as power transformers, instrument transformers, and test transformers. In the power system, it can raise the low voltage generated by the power station to reduce the power loss during the transmission process, and it can also lower the high voltage to meet the power demand of users. It plays a vital role in the fields of power transmission and distribution. Patent application CN114175187A discloses a transformer cooling system, which includes a dry-type transformer. The transformer includes: a core, the core including legs and a winding body disposed around the legs, and a cooling channel extending in the direction of the longitudinal axis of the winding body, wherein the cooling channel is disposed between an inner portion and an outer portion of the winding body. The transformer cooling system also includes a housing for accommodating the dry-type transformer, the housing having an inlet for receiving air from outside the housing and an outlet for discharging air to outside the housing, and a flow generating device disposed at the outlet and adapted to generate negative pressure for drawing air from the inlet toward the flow generating device and discharging air to the outside through the outlet. Compared with traditional transformer equipment, the above-mentioned patented transformer equipment has been improved, especially in terms of device size and cooling efficiency. However, during the use of the transformer, the internal electronic components generate heat when working, and the increase in heat can damage the transformer. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a transformer with a multi-functional cooling system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a transformer with a multi-functional cooling system, including a transformer component, wherein a connecting frame is fixedly connected to the outer wall of the transformer component, and a pneumatic mechanism is fixedly connected to the outer wall of the connecting frame; The pneumatic mechanism includes: The telescopic machine is fixedly connected to the outer wall of the connecting frame; An extrusion plate, which is movably connected to the outer wall of the telescopic machine; The first opening is fixedly connected to one side of the transformer component; A sealing assembly is fixedly connected to the outer wall of the extrusion plate; The second opening is fixedly connected to the other side of the transformer component; A unidirectional component is fixedly connected to the outer wall of the second opening and equipped with a pneumatic mechanism. The reciprocating motion of the extrusion plate driven by the telescopic mechanism enables active circulation of airflow inside the transformer component. When the extrusion plate squeezes the first opening, it forces cold air from the outside into the transformer component. After absorbing heat through the transformer component, the airflow is discharged from the second opening. This forced air cooling method can quickly remove the heat generated inside the transformer by the operation of electronic components, effectively reducing the internal temperature of the transformer, reducing the risk of damage caused by high temperature, and improving the operational stability and reliability of the transformer.

[0005] Preferably, the telescopic machine is fixedly connected to the outer wall of the connecting frame by a bracket.

[0006] Preferably, the telescopic mechanism is inserted into the first open opening via a compression plate.

[0007] Preferably, the sealing assembly includes air bladders, which are fixedly connected to the outer ring of the extrusion plate, and there are two sets of air bladders. A tortuous tube is fixedly connected to the outer wall of the extrusion plate, and a spring is fixedly connected to the outer wall of the extrusion plate. A connecting rod is fixedly connected between the spring and the tortuous tube. Under the action of the spring and the connecting rod, the air bladders in the sealing assembly can tightly fit the first opening and the outer wall of the extrusion plate, which significantly enhances the sealing performance between the extrusion plate and the first opening. This ensures that cold air can efficiently enter the transformer components during the airflow extrusion process, avoids gas leakage, and improves the efficiency of air cooling. At the same time, the baffle and sealing port in the one-way assembly cooperate to open smoothly when the airflow is discharged from the second opening, and effectively prevents the backflow of external airflow when the extrusion plate is reset. This ensures the stable control of the airflow circulation inside the transformer components by the pneumatic mechanism and further optimizes the heat dissipation effect.

[0008] Preferably, the unidirectional component includes a fixing block, which is fixedly connected to the top of the second opening. A baffle is rotatably connected to the outer wall of the fixing block, and a sealing port is fixedly connected to the outer wall of the second opening. When the extrusion plate moves and resets within the first opening, it is in a relatively sealed space. According to thermodynamic principles, as the volume of the space slowly increases, the gas does work on the outside, its internal energy decreases, and its temperature drops. This process creates a local low-temperature environment inside the transformer components, further helping to reduce the overall temperature inside the transformer. This helps to alleviate the aging and damage problems of electronic components caused by continuous high temperatures and extends the service life of the transformer.

[0009] Preferably, the baffle and the fixed block are rotatably connected by a bearing, and the baffle is in active contact with the sealing port.

[0010] Preferably, a cooling mechanism is fixedly connected to the top of the transformer component.

[0011] Preferably, the cooling mechanism includes a first connecting pipe and a second connecting pipe, both of which are fixedly connected to the top of the transformer component. One end of a first pipe is fixedly connected to the bottom of the second connecting pipe, and one end of a second pipe is fixedly connected to the bottom of the first connecting pipe. A cooling chamber is fixedly connected to the other end of the second pipe. A liquid storage tank is fixedly connected to the outer wall of the cooling chamber. A fan is fixedly connected to the other end of the first pipe. The fan is fixedly connected to the outer wall of the cooling chamber. A heat exchange tube is fixedly connected to the inner wall of the cooling chamber at the position of the fan and the second pipe.

[0012] This invention provides a transformer with a multi-functional cooling system. It offers the following advantages: 1. This transformer with a multi-functional cooling system utilizes a pneumatic mechanism and a telescopic conveyor to drive the reciprocating motion of the extrusion plate, thereby achieving active circulation of airflow inside the transformer components. When the extrusion plate presses against the first opening, it forces cold air from the outside into the transformer components. After absorbing heat through the transformer components, the airflow is discharged from the second opening. This forced air cooling method can quickly remove the heat generated inside the transformer by the operation of electronic components, effectively reducing the internal temperature of the transformer, reducing the risk of damage caused by high temperature, and improving the operational stability and reliability of the transformer.

[0013] 2. This transformer with a multi-functional cooling system, through the air bladder in the sealing assembly, under the action of springs and connecting rods, can tightly fit the first opening and the outer wall of the extrusion plate, significantly enhancing the sealing performance between the extrusion plate and the first opening. This ensures that cold air can efficiently enter the transformer components during the airflow extrusion process, avoiding gas leakage and improving the efficiency of air cooling. At the same time, the baffle and sealing port in the one-way assembly cooperate to open smoothly when the airflow exits the second opening, and effectively prevent the backflow of external airflow when the extrusion plate resets, ensuring stable control of the airflow circulation inside the transformer components by the pneumatic mechanism, further optimizing the heat dissipation effect.

[0014] 3. This transformer with a multi-functional cooling system, when the extrusion plate moves and resets within the first open opening, is in a relatively sealed space. According to thermodynamic principles, as the volume of the space slowly increases, the gas does work on the outside, the internal energy decreases, and the temperature drops. This process creates a local low-temperature environment inside the transformer components, further helping to reduce the overall temperature inside the transformer. This helps to alleviate the aging and damage problems of electronic components caused by continuous high temperatures and extends the service life of the transformer.

[0015] 4. This transformer with a multi-functional cooling system, through the cooling mechanism added in Embodiment 2, constructs a circulating insulating oil-cooled heat exchange system through the coordinated work of components such as the first connecting pipe, the second connecting pipe, the first pipe, the second pipe, the cooling chamber, the liquid storage tank, and the fan. The fan drives the airflow to circulate within the system. When the airflow passes through the heat exchange pipe immersed in the insulating oil in the liquid storage tank, it is cooled and carries low-temperature air into the transformer components, further reducing the internal temperature of the transformer. This composite heat dissipation method combining air cooling and insulating oil cooling can more effectively cope with the large amount of heat generated by the transformer during operation compared to a single heat dissipation method, providing a more comprehensive and powerful heat dissipation guarantee for the transformer, greatly improving the heat dissipation performance of the transformer, and effectively solving the problem of transformer damage due to increased internal heat.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0020] Example 1, please refer to Figure 1-6 The present invention provides a technical solution: a transformer with a multi-functional cooling system, including a transformer component 1, a connecting frame 2 fixedly connected to the outer wall of the transformer component 1, and a pneumatic mechanism 3 fixedly connected to the outer wall of the connecting frame 2. Transformer component 1 is placed in the required location for use; The pneumatic mechanism 3 includes: Telescopic machine 32, telescopic machine 32 is fixedly connected to the outer wall of connecting frame 2; Extrusion plate 33 is movably connected to the outer wall of telescopic machine 32; The first opening 35 is fixedly connected to one side of the transformer component 1; Sealing assembly 34 is fixedly connected to the outer wall of extrusion plate 33; The second opening 36 is fixedly connected to the other side of the transformer component 1; One-way component 37 is fixedly connected to the outer wall of the second opening 36.

[0021] The telescopic machine 32 is fixedly connected to the outer wall of the connecting frame 2 via the bracket 31.

[0022] The telescopic mechanism 32 is inserted into the first open port 35 via the extrusion plate 33.

[0023] The sealing assembly 34 includes an airbag 341, which is fixedly connected to the outer ring of the extrusion plate 33. There are two sets of airbags 341. A tortuous tube 344 is fixedly connected to the outer wall of the extrusion plate 33. A spring 342 is fixedly connected to the outer wall of the extrusion plate 33. A connecting rod 343 is fixedly connected between the spring 342 and the tortuous tube 344.

[0024] The one-way component 37 includes a fixing block 371, which is fixedly connected to the top of the second opening 36. A baffle 373 is rotatably connected to the outer wall of the fixing block 371, and a sealing port 374 is fixedly connected to the outer wall of the second opening 36.

[0025] The baffle 373 and the fixed block 371 are rotatably connected by the bearing 372, and the baffle 373 is in active contact with the sealing port 374.

[0026] A first opening 35 is opened on one side of the transformer component 1, and a second opening 36 is opened on the other side of the transformer component 1. The baffle 373 can rotate through the bearing 372. The sealing opening 374 is made of rubber material and is triangular in shape. The baffle 373 will hang down under its own weight, and the hanging of the baffle 373 will squeeze onto the sealing opening 374, thereby sealing the second opening 36. When the telescopic conveyor 32 is powered on, it drives the extrusion plate 33 to move repeatedly. When the telescopic conveyor 32 drives the extrusion plate 33 to squeeze into the first open port 35, it will squeeze the airflow in the first open port 35 into the transformer component 1. After passing through the transformer component 1, the airflow carries the heat in the transformer component 1 and then exits from the second open port 36. When the airflow exits the second open port 36, it will push up the baffle 373. The telescopic conveyor 32 then drives the extrusion plate 33 to reset. At this time, during the reset process, the baffle 373 and the sealing port 374 cooperate to block the second open port 36, thereby preventing the airflow from entering. At this time, the extrusion plate 33 moves in the first open port 35. In a sealed space, when the space increases while the gas volume remains unchanged, the temperature in the space will usually decrease. According to the principle, when the volume of the sealed space slowly increases, the gas needs to do work on the outside. Since the system is adiabatic, the energy for the gas to do work on the outside can only come from the internal energy of the gas itself. The decrease in internal energy will lead to a decrease in the average kinetic energy of the gas molecules. Since temperature is the macroscopic manifestation of the average kinetic energy of molecules, the temperature decreases. Then the extrusion plate 33 moves out from the first opening 35, and at this time the outside gas will re-enter the transformer component 1; The elastic length of the spring 342 is less than the length of the bend tube 344, so the bend tube 344 is pulled by the connecting rod 343, and then the gas in the bend tube 344 enters the airbag 341. The airbag 341 is set on the outer ring of the extrusion plate 33, so that the airbag 341 fits against the first opening 35 and the outer wall of the extrusion plate 33, thereby increasing the sealing between the extrusion plate 33 and the inner wall of the first opening 35.

[0027] Example 2, please refer to Figure 1-8 Based on Embodiment 1, the present invention provides the following technical solution: A cooling mechanism 4 is fixedly connected to the top of transformer component 1.

[0028] The cooling mechanism 4 includes a first connecting pipe 41 and a second connecting pipe 42. Both the first connecting pipe 41 and the second connecting pipe 42 are fixedly connected to the top of the transformer component 1. One end of the first pipe 43 is fixedly connected to the bottom of the second connecting pipe 42. One end of the second pipe 44 is fixedly connected to the bottom of the first connecting pipe 41. The other end of the second pipe 44 is fixedly connected to a cooling chamber 45. A liquid storage tank 46 is fixedly connected to the outer wall of the cooling chamber 45. A fan is fixedly connected to the other end of the first pipe 43. The fan is fixedly connected to the outer wall of the cooling chamber 45. A heat exchange pipe 47 is fixedly connected to the inner wall of the cooling chamber 45 at the position of the fan and the second pipe 44. The first connecting pipe 41 and the second connecting pipe 42 are located at the top of the transformer component 1 and are connected to the interior of the transformer component 1. The second connecting pipe 42, the first pipe 43, the fan, the heat exchange pipe 47, the second pipe 44, the first connecting pipe 41, and the transformer component 1 form a circulating space. When the fan is powered on and started, it will drive the airflow to circulate. An appropriate amount of insulating oil is added to the liquid storage tank 46. The liquid storage tank 46 is connected to the cooling chamber 45. The cooling chamber 45 is then placed outside the heat exchange pipe 47, thereby immersing the heat exchange pipe 47 in the insulating oil. The insulating oil cools the heat exchange pipe 47. Then, when the airflow passes through the interior of the heat exchange pipe 47, it will carry low-temperature air into the transformer component 1. The insulating oil is preferably the insulating oil used inside wet transformers, which is a conventional product and will not be described in detail.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
