Description

However, since a large amount of heat is generated during its operation, how to effectively dissipate heat has become one of the key issues to ensure the stable operation of the transformer. The traditional heat dissipation method mainly relies on natural air convection. Although this method is simple and easy to use, it is less efficient in high temperature environments and easily causes the internal temperature of the transformer to be too high, thus affecting its performance and service life.

The heat sink is provided with a number of heat dissipation pipes, and the heat dissipation pipe includes a connected transition center tube and a number of oil passage chambers, and the oil passage chamber is a hollow inverted water drop shape.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Example 1

[0032] As attached Figures 1 to 8A transformer with an adaptive temperature control structure shown in the figure includes a shell 1, which is a multi-layer structure. The shell 1 is designed to be a container that can accommodate all internal components to ensure sufficient strength and safety. The surface of the shell 1 is usually subjected to anti-corrosion treatment, such as painting or hot-dip galvanizing, to enhance weather resistance and corrosion resistance and protect internal parts from external environmental influences, such as humidity, pollution and physical damage. A transformer main oil pillow 2 is arranged on one side of the top of the shell 1. The transformer main oil pillow 2 is made of oil-resistant and high-temperature resistant rubber or synthetic material, is designed to be a container that can store and adjust insulating oil, has an interface for connecting to the outside world, and automatically adjusts the oil volume according to the thermal expansion and contraction of the transformer oil to ensure the normal operation of the transformer, facilitate the inspection and maintenance of the insulating oil, and extend the service life of the transformer. In order to extend the service life, a high-voltage porcelain bushing 3 is arranged on one side of the main oil pillow 2 of the transformer, and a low-voltage porcelain bushing 4 is arranged on one side of the high-voltage porcelain bushing 3. The high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4 are made of high-quality ceramic materials, and are precisely formed and fired at high temperatures. They are designed as hollow cylindrical structures to wrap the cables and pass through the transformer shell, so as to provide electrical insulation for the high-voltage and low-voltage lead-out wires, prevent electrical leakage and protect the cables from external physical damage. A three-phase winding 5 is arranged below the high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4. The three-phase winding 5 uses copper wire or aluminum wire with high conductivity. The wire is evenly wound on the iron core by a professional winding machine to form a winding, which realizes the conversion of electrical energy to magnetic energy under the action of the electromagnetic field. It is the core component of the transformer for voltage conversion.

[0033] A cooling chamber 6 is provided on one side of the three-phase winding 5. The cooling chamber 6 is designed as a streamlined cavity to ensure that the coolant or gas can flow efficiently. The cooling chamber 6 is located near the heat-generating part of the transformer to optimize the heat dissipation path. By guiding the cooling medium to flow through, the heat generated during the operation of the transformer is effectively taken away, and the equipment is kept running at a suitable temperature. A coupling mechanism 7 is provided on one side of the cooling chamber 6. The coupling mechanism 7 includes a protective shell 701, a main through-tube 702, an auxiliary through-tube 703, and a connecting mechanism 704. The various parts are made of metal or high-temperature resistant plastic material and are made by mechanical processing. They are accurately assembled according to the design drawings, and the temperature is monitored through the built-in temperature sensor 19, and the connecting mechanism 704 is driven by the temperature sensor 19. The coupling mechanism 704 adjusts the flow of cooling oil to meet different heat dissipation requirements. An auxiliary cooling mechanism 8 is provided on one side of the coupling mechanism 7. The auxiliary cooling mechanism 8 includes components such as a circulation passage 801, a heat dissipation pipe 802, a heat sink 803, a liquid delivery pump 804 and a water storage tank 805. It is ensured that all components are reasonably connected to form an effective cooling circulation system. When the main cooling system is not sufficient to cope with the heat generated by high load, the auxiliary cooling mechanism 8 is connected through the coupling mechanism 7 to provide additional cooling capacity for the insulating oil in the transformer. A fire fighting mechanism 9 is provided on one side of the auxiliary cooling mechanism 8 to quickly release carbon dioxide fire extinguishing agent to control or extinguish the fire when a fire is detected;

[0034] The shell 1 includes a first insulation layer 101, a second insulation layer 102 and a third insulation layer 103. The first insulation layer 101 is usually made of a material with high thermal resistance, such as polyurethane foam or mineral wool. During the manufacturing process, a liquid or fibrous insulation material is filled or wrapped in the inner layer of the transformer shell 1, and a certain thickness is left to form the first insulation layer 101. As the outermost layer, its main function is to reduce the influence of the external low temperature on the internal temperature of the transformer, and to reduce the heat loss of the internal high temperature to the external environment. The first insulation layer 101 is provided with a third insulation layer 103. The second insulation layer 102 can use materials similar to the first insulation layer 101, but can also use materials of different density or thickness to enhance the thermal insulation effect. During construction, the second insulation layer 102 is close to the first insulation layer 101 and further wraps the transformer housing 1. The second insulation layer 102 enhances the overall thermal insulation effect, ensuring that the transformer can maintain a stable internal temperature under different ambient temperatures to avoid energy waste. The interior of the second insulation layer 102 is provided with a third insulation layer 103, and the inner wall of the third insulation layer 103 is serrated. The third thermal insulation layer 103 uses more advanced thermal insulation materials, such as aerogel board or high-density aluminum silicate fiber, to provide extreme thermal insulation performance. The third thermal insulation layer 103 is arranged inside the second thermal insulation layer 102, directly surrounding the core components of the transformer. The serrated inner wall increases the contact area with the core components. The main function of the third thermal insulation layer 103 is to provide the most direct protection for the core components of the transformer and maintain the optimal temperature during operation, thereby improving equipment efficiency and extending service life. A dust cover 10 is arranged on the top of the first thermal insulation layer 101. The dust cover 10 is connected to the transformer body through the dust cover 10. Weather-resistant plastic or lightweight metal is often used, which is fixed to the top of the transformer housing 1 by bolts 11, and is easy to open for maintenance, so as to prevent dust and other foreign matter from entering the interior of the transformer, reduce maintenance costs and extend the life of the equipment. Bolts 11 are arranged on the top of the dust cover 10, and several groups of bolts 11 are arranged, and each group of bolts 11 is evenly arranged along the circumferential direction of the dust cover 10. The dust cover 10 is combined with the first insulation layer 101 by bolts 11. The bolts 11 are usually made of high-strength steel or stainless steel to ensure sufficient structural strength and corrosion resistance.

[0035] Example 2

[0036] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 8 As shown, see the following description for details:

[0037] As a preferred embodiment, an oil pillow support 12 is provided at the bottom of the transformer main oil pillow 2. The oil pillow support 12 is mostly made of metal material and is fixed to the transformer body by welding or the like to ensure that the transformer main oil pillow 2 can be stably supported and allow a certain amount of thermal expansion and contraction displacement, thereby providing a stable supporting foundation for the transformer main oil pillow 2. Connecting flanges 13 are provided on both sides of the oil pillow support 12. The oil pillow support 12 fixes the transformer main oil pillow 2 through the connecting flanges 13. The connecting flanges 13 are usually made of cast iron or steel material, which is machined to meet the size requirements, and are connected to the transformer main oil pillow through bolts 11 and the oil pillow support 12. 2 is tightly connected, which plays a role in ensuring that the connection between the transformer main oil pillow 2 and the transformer body is both firm and has good sealing performance. A quick connector 14 is arranged below the transformer main oil pillow 2, and a connecting pipe 15 is arranged below the quick connector 14. The quick connector 14 is connected to the coupling mechanism 7 through the connecting pipe 15. The quick connector 14 and the connecting pipe 15 are usually made of oil-resistant rubber or synthetic materials, and are designed to facilitate quick connection and ensure sealing performance. The quick connector 14 is used to conveniently connect or disconnect the oil circuit, while the connecting pipe 15 ensures that the oil circuit is unobstructed, which simplifies the connection and disconnection operations of the oil circuit and makes daily maintenance more convenient and efficient.

[0038] As a preferred embodiment, a fixing sleeve 16 is provided at the bottom of the high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4. The fixing sleeve 16 is usually made of weather-resistant and corrosion-resistant metal, such as stainless steel or galvanized steel, to ensure durability for long-term use. The basic shape of the fixing sleeve 16 is formed by stamping or casting, and then the size is precisely machined to ensure that it can closely match the external dimensions of the porcelain bushing, provide stable mechanical fixation for the high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4, prevent them from moving under external force or operating conditions, and reduce the vibration of the porcelain bushing during the operation of the transformer through a firm installation, thereby extending the service life of the equipment. A slot 17 is provided below the fixing sleeve 16, and the slot 17 is provided with several groups, and Each group of slots 17 is evenly arranged along the horizontal direction of the dust cover 10. The slots 17 are located below the fixed sleeve 16 and are a part of the fixed sleeve 16 or a preset opening on the transformer housing 1. During the production process of the transformer housing 1 or the fixed sleeve 16, these slots 17 are directly formed by mechanical cutting or mold casting, providing a simple way to install the high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4. The staff can directly align the porcelain bushing with the slots 17 and place them in place. The high-voltage porcelain bushing 3 and the low-voltage porcelain bushing 4 are both installed on the dust cover 10 through the fixed sleeve 16 and the slots 17. The combined use of the slots 17 and the fixed sleeve 16 can strengthen the connection between the porcelain bushing and the transformer housing 1 and improve the overall structural stability.

[0039] As a preferred embodiment, the coupling mechanism 7 includes a protective shell 701, a main through-tube 702, an auxiliary through-tube 703 and a connecting mechanism 704. The protective shell 701 is usually made of a high-temperature resistant and corrosion-resistant metal material, such as stainless steel. The shell structure for accommodating and protecting the internal components is formed by metal processing technology, which plays a role in protecting the internal main through-tube 702, the auxiliary through-tube 703 and the connecting mechanism 704 from the influence of the external environment, such as dust, moisture and other potential hazards. A main through-tube 702 is arranged on one side of the interior of the protective shell 701. The main through-tube 702 is made of a material with high thermal conductivity, such as copper or aluminum, to optimize the heat transfer efficiency. It is manufactured through conventional production processes of metal pipes, including casting, rolling and machining steps, and serves as the main channel for the flow of cooling medium (usually oil or liquid) to help take heat away from the core part of the transformer. A heat exchanger 704 is arranged below the main through-tube 702. There is an auxiliary through-pipe 703, which is made of high thermal conductivity material, and the size and shape are optimized according to the characteristics of the components that need to dissipate heat. When the main cooling system is not enough to cope with the heat, an additional cooling path is provided to ensure that the temperature of key components is controlled within a safe range. A connecting mechanism 704 is provided on one side of the auxiliary through-pipe 703. The connecting mechanism 704 includes a driving guide rail 7041, a driving baffle 7042, a sealing layer 7043, a roller 7044, a driving box 7045 and a driving motor 7046. There are two sets of driving guide rails 7041. The driving guide rails 7041 are usually made of high-hardness and smooth metal or synthetic materials to ensure durability and reduce friction. The precise shape and size of the guide rails are formed through mechanical processing such as milling, grinding and other processes to provide a stable linear motion path for the driving baffle 7042, ensuring that the driving baffle 7042 can move up and down smoothly;

[0040] A driving baffle 7042 is arranged in the middle of the two sets of driving guide rails 7041. The driving baffle 7042 is made of a heat-resistant material with sufficient strength. The shape is designed to maximize the coverage and sealing performance. It is manufactured through cutting and forming processes to ensure that it is compatible with the driving guide rails 7041 and the sealing layer 7043. The cooling medium flowing to the auxiliary through-pipe 703 is blocked or opened as needed to adjust the cooling flow and effect. A sealing layer 7043 is arranged on one side of the outer wall of the driving baffle 7042. The sealing layer 7043 uses a flexible material that is resistant to high temperature and oil corrosion, such as rubber or synthetic rubber, and is fixed to the periphery of the driving baffle 7042 to enhance its sealing performance and ensure that when the driving baffle 7042 is closed, the cooling medium will not leak from the main through-pipe 702 to the auxiliary through-pipe 703. A roller 7044 is arranged on one side of the sealing layer 7043. The roller 7044 is arranged in two groups, and the two groups of rollers 7044 The driving baffle 7042 is symmetrically arranged in the horizontal direction. The roller 7044 is made of wear-resistant material such as steel or nylon and is made into a smooth roller through precision machining, so that the driving baffle 7042 can move more smoothly and easily along the driving guide rail 7041. A driving box 7045 is arranged on one side of the driving baffle 7042. The driving box 7045 installs the driving motor 7046 and other mechanical transmission components inside it to ensure that all parts are properly aligned and connected, protect the internal transmission mechanism, and effectively transmit power to the driving baffle 7042. A driving motor 7046 is arranged on one side of the driving box 7045 through an electric wire. The driving motor 7046 should be an electric motor suitable for low-speed and high-torque applications, and have an appropriate protection level to adapt to harsh environments. The driving motor 7046 drives the driving box 7045 to drive the driving baffle 7042 to move up and down along the driving guide rail 7041 through the roller 7044.

[0041] As a preferred embodiment, the auxiliary cooling mechanism 8 includes a circulation passage 801, a heat dissipation pipe 802, a heat sink 803, a liquid delivery pump 804 and a water storage tank 805. The circulation passage 801 is usually made of high temperature resistant and corrosion resistant materials, such as stainless steel or plastic, and is designed to be a piping system capable of accommodating and guiding the flow of the cooling medium to ensure that the fluid circulates efficiently in the system. As a circulation channel for the cooling medium, it ensures that the coolant can smoothly reach each component. A heat dissipation pipe 802 is provided on one side of the circulation passage 801, and the heat dissipation pipe 802 is made of high thermal conductivity. Materials, such as copper or aluminum, are used to improve the efficiency of heat conduction. They are made through mechanical processing technology, including welding, rolling and other processes. The inner wall of the pipe is ensured to be smooth to reduce resistance, and the heat inside the transformer is quickly conducted to the heat sink 80, effectively reducing the temperature of the transformer. A heat sink 803 is provided on one side of the heat pipe 802. Materials with good thermal conductivity, such as aluminum alloy or copper alloy, are used. They are usually designed as porous or fin-like structures to increase the heat dissipation area and improve the heat dissipation effect. The heat dissipation is accelerated by increasing the surface area, so that the cooling medium can absorb more effectively. Heat, three groups of heat sinks 803 are arranged evenly along the vertical direction of the heat pipe 802. This design uses three layers of superimposed heat sinks 803, each layer has an independent heat dissipation path, which increases the total heat dissipation area. The existence of the gap in the middle not only improves the efficiency of air flow, but also allows hot air to be discharged more easily, thereby further improving the heat dissipation performance. At the same time, under high load or high temperature environment, the three layers of superimposed heat sinks 803 can quickly disperse heat and avoid local overheating, thereby extending the service life of the transformer and reducing the failure rate. A liquid delivery pump 804 is arranged on one side of the heat sink 803. The liquid delivery pump 804 should use a water pump that can adapt to high temperature environment, usually has high temperature resistance and corrosion resistance, provides sufficient pressure and flow, and ensures that the cooling medium can be continuously and stably circulated in the entire cooling system. A water storage tank 805 is arranged on one side of the liquid delivery pump 804. The water storage tank 805 usually uses corrosion-resistant and high temperature resistant materials, such as stainless steel or special plastics, as a storage container for the cooling medium. When needed, the system is replenished with coolant to maintain the continuous cooling capacity of the system.

A hydrochloric acid tank 902 is arranged on one side of the electric-controlled valve 901. The hydrochloric acid tank 902 is made of acid-resistant materials, such as polyethylene or fiberglass. Necessary safety valves and pressure release devices should be arranged on it to prevent explosion due to excessive internal pressure. A bicarbonate tank 903 is arranged on one side of the hydrochloric acid tank 902. The bicarbonate tank 903 Alkali corrosion-resistant materials such as stainless steel or plastic are usually used, and the design is to store enough bicarbonate to meet the fire extinguishing needs. When a fire occurs, it reacts with hydrochloric acid and water to generate carbon dioxide gas, which is used to cover the fire source and reduce the oxygen concentration. A jet plate 904 is arranged on one side of the bicarbonate tank 903. The jet plate 904 includes a fixed frame 9041 and a jet head 9042. The fixed frame 9041 is provided with a jet head 9042 inside. The jet head 9042 is provided with several groups, and each group of jet heads 9042 is evenly arranged along the vertical direction of the fixed frame 9041. The jet heads 9042 are evenly distributed on the fixed frame 9041 to ensure that the carbon dioxide can evenly cover the surface of the fire source, and the flame is extinguished by spraying carbon dioxide gas, thereby reducing the temperature of the fire source and suppressing the spread of the flame.

[0043] As a preferred embodiment, a smoke sensor 18 is provided on one side of the fixing frame 9041, and one side of the smoke sensor 18 is connected to the electric control valve 901. By controlling the electric control valve 901 to open, the water in the auxiliary cooling mechanism 8 enters the hydrochloric acid tank 902 and the bicarbonate tank 903 to generate carbon dioxide, and the generated carbon dioxide is sprayed on the outer shell 1 through the jet plate 904. Furthermore, the model of the smoke sensor 18 is Honeywell HS10X series, which is suitable for commercial buildings and industrial facilities, and has high sensitivity and low false alarm rate. The smoke sensor 18 is installed on one side of the fixing frame 9041 to ensure that the fire signal inside the transformer can be detected in time. The close cooperation between the smoke sensor 18 and the electric control valve 901 enables the entire fire extinguishing process to be quickly started at the early stage of the fire, effectively reducing the risk of fire spread. By spraying carbon dioxide gas, the fire source area can be effectively covered, the oxygen concentration can be reduced and heat can be absorbed, thereby quickly extinguishing the flame.

[0044] As a preferred embodiment, a temperature sensor 19 is provided on one side of the main through-pipe 702, one side of the temperature sensor 19 is connected to the drive motor 7046, and the other side of the temperature sensor 19 is located inside the cooling chamber 6. The temperature of the cooling oil inside the cooling chamber 6 is monitored by the temperature sensor 19, so that the drive motor 7046 drives the drive baffle 7042 to move up and down, so that the cooling oil enters the auxiliary cooling mechanism 8 through the auxiliary through-pipe 703. Furthermore, the model of the temperature sensor 19 is Honeywell RSC series. This series of products can work stably under extreme temperature conditions and is suitable for various complex industrial environments. The temperature sensor 19 monitors the temperature changes in the cooling chamber in real time, and can accurately control the flow and direction of the cooling oil to ensure that the transformer operates in the best working state. In a high temperature environment, the adjustment of the drive baffle can allow more cooling oil to flow into the auxiliary cooling mechanism 8, thereby improving the heat dissipation efficiency and preventing the equipment from overheating. This adaptive temperature control design can effectively cope with different working environments and load conditions, and ensure the stable operation and long service life of the transformer.

[0045] The working process of the present application is as follows: a temperature sensor 19 is provided on one side of the main through-tube 702, and the temperature sensor 19 monitors the cooling oil temperature inside the cooling chamber 6 in real time. When the temperature is detected to exceed the set value, the temperature sensor 19 will trigger the corresponding control system. The other side of the temperature sensor 19 is connected to the drive motor 7046. The drive motor 7046 drives the drive baffle 7042 to move up and down along the main through-tube 702 through a mechanical transmission device. Specifically, the drive baffle 7042 will adjust its position as needed, thereby changing the flow rate and flow direction of the cooling oil. When the drive baffle 7042 moves downward, the cooling oil enters the auxiliary cooling mechanism 8 through the auxiliary through-tube 703 to enhance the heat dissipation effect. This process ensures that the temperature inside the transformer is effectively controlled in a high temperature environment.

[0046] When the smoke sensor 18 detects the generation of flames, in the auxiliary cooling mechanism 8, water enters the hydrochloric acid tank 902 and the bicarbonate tank 903 to undergo a chemical reaction to generate carbon dioxide gas, which is then sprayed on the transformer housing 1 through the jet plate 904 to extinguish the flame and reduce the temperature. At the same time, the smoke sensor 18 continuously monitors the environmental conditions to ensure a rapid response at the initial stage of a fire. After the water enters the hydrochloric acid tank 902 and the bicarbonate tank 903, a chemical reaction occurs to generate carbon dioxide gas. This chemical reaction not only quickly and efficiently generates fire extinguishing agents, but also avoids the secondary problems that may be caused by the use of traditional fire extinguishing agents.

[0047] The temperature sensor 19 monitors the cooling oil temperature inside the cooling chamber 6 in real time to ensure that any abnormal temperature rise can be discovered in time. When it is detected that the temperature exceeds the preset threshold, the temperature sensor 19 immediately sends a signal to the drive motor 7046 to start the corresponding control measures. The drive motor 7046 drives the baffle 7042 to move up and down through the mechanical transmission device to accurately control the flow and direction of the cooling oil. By optimizing the adjustment strategy of the baffle, it is ensured that the cooling oil can cover the entire cooling area in the shortest time, thereby improving the heat dissipation efficiency.
