Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to a cooling device for transformers.

Background Art

[0002] A transformer is a power facility necessary for power generation technology. Due to material constraints, part of the electrical energy is converted into extra heat energy during operation, and the heat generated by the losses of the windings and the core needs to be quickly dissipated to prevent insulation damage due to overheating. For transformers with different powers, the existing cooling methods for transformers are diverse, mainly including natural air cooling, forced air cooling, oil-immersed self-cooling, and oil-immersed air cooling.

[0003] Among them, in a substation, when cooling several high-power transformers, the method of forced oil-immersed air cooling is often adopted for the heat dissipation of the transformers. In such a method, an oil pump is used to circulate the cooling oil, and then a fan is used to dissipate the heat of the cooling oil. However, in summer, due to the high external temperature, it is difficult to ensure sufficient heat dissipation intensity in the cooling system of the transformer.

[0018] To make the above objects, features, and advantages of the present invention clearer and easier to understand, the following will describe the specific embodiments of the present invention in detail in conjunction with the accompanying drawings of the specification.

[0019] To facilitate a complete understanding of the present invention, many specific details are described below. However, the present invention can also be implemented in other ways different from those described in this specification. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific examples disclosed below.

[0020] Also, as used herein, "one embodiment" or "an embodiment" refers to specific features, structures, or characteristics that may be included in at least one embodiment of the present invention. The phrase "in one embodiment" appearing at different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment from other embodiments.

[0021] Furthermore, when the present invention is described in detail in conjunction with schematic diagrams and the embodiments of the present invention are elaborated, for the sake of facilitating the explanation, the cross-sectional view showing the structure of the device is partially enlarged regardless of the normal scale, and moreover, the schematic diagram is merely illustrative and does not limit the protection scope of the present invention. Note that during actual production, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] Embodiment 1 Referring to FIGS. 1 to 3, the first embodiment of the present invention provides a cooling device for a transformer, and the cooling device for the transformer includes an oil tank 100, the interior of the oil tank 100 is used for installing a transformer, an oil conservator 200 is fixedly provided on the top of the oil tank 100, and cooling oil is stored inside the oil conservator 200, the said oil tank 100, a cooling assembly 300 including a blowing member 301 and an oil delivery member 302 provided on one side of the oil tank 100, and a rotating member 303 and a temperature reduction member 304 provided on one side of the oil delivery member 302, The system includes an auxiliary assembly 400 which comprises a storage member 401 provided on one side of the blowing member 301, and a spraying member 402 provided on the same side as the blowing member 301.

[0023] During use, the transformer is installed inside the oil tank 100, the inside of the oil tank 100 is filled with cooling oil, the oil conservator 200 can replenish the cooling oil in a timely manner when the cooling oil inside the oil tank 100 leaks, the cooling assembly 300 is mainly used for transporting the cooling oil and dissipating heat from the cooling oil, and the auxiliary assembly 400 can enhance the cooling effect of the cooling assembly 300 as auxiliary equipment.

[0024] Example 2 Referring to Figures 2 to 6, the differences between the second embodiment of the present invention and the first embodiment are as follows: The blower member 301 comprises an air chamber 301a, a rack 301b, a motor 301c, and a fan 301d. The air chamber 301a is fixedly mounted on the side of the oil tank 100. There are two racks 301b, fixedly mounted at the bottom and top of the air chamber 301a, respectively. The motor 301c is fixedly mounted inside each rack 301b. The fan 301d is fixedly mounted at the output terminal of the motor 301c. After the motor 301c is started, it rotates the fan 301d. The fans 301d at the top and bottom of the air chamber 301a rotate in opposite directions. When the fan 301d rotates, it can form an airflow from the top to the bottom of the air chamber 301a.

[0025] When the fan 301d rotates, the top fan 301d blows air into the air chamber 301a, and the bottom fan 301d blows air outwards from the air chamber 301a. As a result, the airflow inside the air chamber 301a flows from top to bottom, allowing it to make full contact with the conduit. On the other hand, when a conventional fan 301d performs cooling, the two fans 301d blow air perpendicular to the conduit, which limits the contact area between the airflow and the conduit, reducing the heat dissipation efficiency of the cooling oil.

[0026] The oil supply member 302 comprises an oil supply pipe 302a and an oil pump 302b. The oil supply pipe 302a is connected to the outside of the oil tank 100, and the outlet of the oil pump 302b is connected to the outside of the bottom of the oil tank 100. The oil pump 302b is used to draw the cooling oil, after it has absorbed heat, from the top of the oil tank 100 to the outside, and to transport the cooling oil to the bottom of the oil tank 100 after the cooling assembly 300 has dissipated the heat from the cooling oil, thereby forming a circulation of the cooling oil.

[0027] The oil supply member 302 further comprises a spiral pipe 302c and a side edge plate 302d, the oil supply pipe 302a extends through the outside of the air chamber 301a into the interior, the spiral pipe 302c is rotatably provided at one end of the oil supply pipe 302a away from the oil tank 100, and the other end of the spiral pipe 302c away from the oil supply pipe 302a is rotatably provided at the inlet of the oil pump 302b, the spiral pipe 302c is located between the oil supply pipe 302a and the oil pump 302b, and compared to a conventional straight pipe The spiral tube 302c extends the time the cooling oil passes through the cooling device, thereby increasing the heat dissipation effect of the cooling oil. The side edge plates 302d are fixedly installed surrounding the sides of the spiral tube 302c. The side edge plates 302d are spiral in shape and surround the sides of the spiral tube 302c. The side edge plates 302d are mainly used in conjunction with the blower member 301 and the spray member 402, thereby maximizing the use of the spiral shape of the spiral tube 302c and achieving the objective of increasing the heat dissipation effect of the cooling oil.

[0028] The rotating member 303 comprises a ring member 303a, a support bar 303b, a curved plate 303c, an air guide cover 303d, a ring member 303e, a support bar 303f, and a curved plate 303g. The ring member 303a is fixedly fitted to the top end of the spiral tube 302c, the support bar 303b is fixedly provided on one side of the ring member 303a, the curved plate 303c and the air guide cover 303d are fixedly provided on the side of the support bar 303b, and the air guide cover 303d is attached to the ring member 30 of the curved plate 303c. Located on the side closer to 3a, the outer wall of the air guide cover 303d can guide the airflow to the middle section and assist the operation of the cooling member 304. The ring member 303e is fitted and fixedly attached to the bottom end side of the spiral tube 302c. The support bar 303f is fixedly attached to one side of the ring member 303e. The curved plate 303g is fixedly attached to the side of the support bar 303f. The curved plates 303c and 303g function like turbines, rotating the support bar by receiving airflow, and further enabling the rotation of the spiral tube 302c.

[0029] Here, when the spiral tube 302c begins to rotate due to the drive of the rotating member 303, the side edge plate 302d comes into contact with the airflow in the air chamber 301a, and the airflow forms a spiral. This increases the time that the airflow around the spiral tube 302c is in contact with the spiral tube 302c, thereby enhancing the heat dissipation effect of the cooling oil by the cooling assembly 300.

[0030] The cooling member 304 comprises a central shaft 304a, a windbreak cover 304b, a ventilation pipe 304c, an intermediate cover 304d, an intake pipe 304e, an exhaust pipe 304f, and an exhaust pipe 304g. The central shaft 304a is fixedly mounted on the side of the spiral pipe 302c, the windbreak cover 304b is rotatably mounted on the side of the central shaft 304a via a bracket, the ventilation pipe 304c is connected to the bottom of the windbreak cover 304b, the windbreak cover 304b receives airflow from top to bottom, the air guide cover 303d increases the airflow rate received by the windbreak cover 304b, and the intermediate cover 304d is connected to the side of the ventilation pipe 304c. The intermediate cover 304d is connected to the surface, and multiple exhaust ports are provided inside it. The intake pipe 304e is fixedly installed inside the intermediate cover 304d and is connected to the intermediate cover 304d via the exhaust ports. Exhaust pipe 304f and exhaust pipe 2 304g are connected to different sides of the intake pipe 304e, with exhaust pipe 304f located on the side of the intake pipe 304e away from the vent pipe 402c. The airflow inside the windshield cover 304b flows into the vent pipe 304c, then through the vent pipe 304c to each intermediate cover 304d, and further through each exhaust port of the intermediate cover 304d into the interior of the intake pipe 304e.

[0031] The cooling member 304 further comprises arc-shaped teeth 304h, a frustocone 304i, an air guide ring 304j, and an air blockage groove 304k. The arc-shaped teeth 304h are fixedly provided on the inside of the air intake pipe, the frustocone 304i is fixedly provided at the opening of the exhaust pipe 2 304g, the air guide ring 304j is fixedly provided at the connection between the exhaust pipe 1 304f and the intake pipe 304e, and the air blockage groove 304k is provided on the inner wall of the exhaust pipe 2 304g.

[0032] The intake pipe 304e, exhaust pipe 304f, and exhaust pipe 304g form a structure similar to a vortex tube. A vortex tube is a device that generates cold air by utilizing the viscous friction effect between the inner and outer swirling flow layers of compressed gas inside the tube. Its main operating process is that compressed gas enters the vortex tube and forms a vortex. The rotational angular velocity of the vortex increases as it approaches the center, and friction occurs between the layers of the vortex due to the difference in angular velocity. The angular velocity of the airflow in the central part is the greatest, and energy is transferred to the outer layer airflow, which has a lower angular velocity, due to friction. The airflow in the central layer loses energy, its kinetic energy decreases, its speed and temperature decrease, and it forms a cold airflow. Meanwhile, the airflow in the outer layer gains momentum, its kinetic energy increases, and at the same time, some of the kinetic energy is converted into thermal energy by friction with the inner wall of the vortex tube, which is released from the other end of the vortex tube, forming a hot airflow.

[0033] However, compared to conventional vortex tubes, the cooling member 304 offers the following improvements. First, the setting of the arc-shaped teeth 304h improves the vortex strength inside the exhaust pipe 304g. Second, the setting of the wind-blocking groove 304k further reduces the vortex velocity of the outer layer airflow inside the exhaust pipe 304g. As a result, the inner layer vortex inside the exhaust pipe 304g consumes more internal energy to move the outer layer airflow, and consequently the temperature of the inner layer airflow is further reduced. Furthermore, the intermediate cover 304d divides the airflow from the ventilation pipe 304c into multiple streams and directs them into the intake pipe 304e, forming a vortex of uniform strength. This avoids the collision of airflows of different strengths and the waste of internal energy of the gas in unnecessary places.

[0034] During use, as the operating time of the transformer increases, the cooling oil in the oil tank 100 continuously absorbs the heat released from the transformer. After heating, the cooling oil collides and floats upward, and is absorbed into the spiral tube 302c through the oil supply pipe 302a by the action of the oil pump 302b. The airflow formed by the blower member 301 collides with the transmission member, thereby rotating the spiral tube 302c. The rotating spiral tube 302c makes sufficient contact with the airflow using the side edge plates 302d, thereby enhancing the heat dissipation effect of the cooling assembly 300. As the spiral tube 302c rotates, the heat of the cooling oil is continuously removed by the airflow.

[0035] A portion of the airflow passes through the intermediate cover 304d and enters the intake cover, forming a vortex guided by the arc-shaped teeth 304h. Due to the blockage by the air guide ring 304j, most of the vortex enters the intake pipe 304e, where it splits into two flows, a cold airflow and a hot airflow, according to the principle of vortex flow. As it passes through the frustocone 304i, the outer hot airflow flows out from the intake pipe 304e, while the inner cold airflow is blocked. As the airflow accumulates, the cold airflow flows out from the exhaust pipe 304f. Since the exhaust pipe 304f is close to the spiral pipe 302c, the cold airflow further cools the spiral pipe 302c, enhancing the heat dissipation effect of the cooling assembly 300.

[0036] The other structural features are the same as those in Example 1.

[0037] Example 3 Referring to Figures 7 to 9, the third embodiment of the present invention differs from the second embodiment as follows: the storage member 401 comprises a water storage tank 401a, a screen 401b, a cross plate 401c, a partition plate 401d, a water passage hole 401e, a stepped column 401f, a stopper rod 401g, a limit plate 401h, and a buoyancy plug 401i. The water storage tank 401a is fixedly installed on top of the wind chamber 301a, and the water storage tank 401a is installed outdoors and can normally receive rainwater from outside. The screen 401b is located on top of the water storage tank 401a. Screen 401b is fixedly installed in the section and is mainly used to prevent waste from entering the water storage tank 401a; crossing plate 401c is fixedly installed inside the water storage tank 401a and is arranged to cross along different heights inside the water storage tank 401a and is mainly used to block water vapor when moisture evaporates and to allow the water vapor to condense on the crossing plate 401c and flow back into the water storage tank 401a; partition plate 401d is fixedly installed inside the water storage tank 401a and divides the internal space of the water storage tank 401a vertically.

[0038] The water passage hole 401e opens in the center of the partition plate 401d, and the stepped column 401f is slidably installed inside the water passage hole 401e. The stepped column 401f is divided into a thick section and a thin section, and the thick section slides from the water passage hole 401e, allowing water from the top of the water storage tank 401a to flow to the bottom of the water storage tank 401a through the gap between the thin section of the stepped column 401f and the water passage hole 401e. The stopper rod 401g is located at the stepped column 401f. A stopper rod 401g is fixedly provided at the top and used to restrict the stepped column 401f from coming out of the water passage hole 401e, both ends of the limit plate 401h are fixedly provided on the outside of the stepped column 401f and the bottom of the stopper rod 401g, mainly to ensure that the stepped column 401f can always slide along the inner wall of the water passage hole 401e when it slides, and a buoyancy plug 401i is fixedly provided at the bottom of the stepped column 401f.

[0039] The spraying member 402 comprises a water supply pipe 402a, a nozzle 402b, a vent pipe 402c, a slide base 402d, an arc-shaped block 402e, a spring 402f, and an extrusion ring 402g. The water supply pipe 402a is connected to the lower half of the water storage tank 401a, and one end of the water supply pipe 402a away from the water storage tank 401a extends through the rack 301b into the interior. The nozzle 402b is connected to the end of the water supply pipe 402a, and one end of the vent pipe 402c is connected to the bottom of the water storage tank 401a. The end penetrates the outer wall of the air chamber 301a and extends into the interior of the rack 301b, the slide frame 402d is slidably mounted on the inner wall of the ventilation pipe 402c, the arc-shaped block 402e is fixedly mounted on the end of the slide frame 402d, both ends of the spring 402f are fixedly mounted on the side of the slide frame 402d and the inside of the ventilation pipe 402c, the extrusion ring 402g is fitted to the output end of the motor 301c, and the side wall of the extrusion ring 402g is slidably fitted with the arc-shaped block 402e.

[0040] When in use, the water storage tank 401a needs to be divided into two parts to form a sealed space. If there is no partition plate 401d, when the spraying member 402 applies pressure, the pressure will flow out from the top of the water storage tank 401a, and at this time, the amount of water mist discharged from the nozzle 402b will decrease. If there is enough water in the water storage tank 401a, the auxiliary assembly 400 will perform the following roles: first, after the fan 301d rotates, the side wall of the extrusion ring 402g pushes out the arc-shaped block 402e, and the arc-shaped block 402e slides onto the frame. When 402d is slid, after the sliding frame 402d has slid, the lower part of the water storage tank 401a is pushed out. Since the water storage tank 401a is sealed, the pushed-out water flow is discharged from the nozzle 402b along the water supply pipe 402a, forming a water mist which is then blown into the air chamber 301a by the fan 301d. At the same time, the side edge plate 302d collects the water mist and forms water droplets, which can absorb heat from the spiral tube 302c as they flow along the side edge plate 302d, thereby improving the heat dissipation effect of the spiral tube 302c.

[0041] When the water flow at the bottom of the water storage tank 401a is lost, the buoyancy plug 401i slides downward, and the water flow from the water storage tank 401a flows from the top to the bottom. This replenishes the water in the bottom of the water storage tank 401a, the water supply pipe 402a, and the vent pipe 402c, making the next spraying possible.

[0042] The other structural features are the same as those in Example 2.
