Description

Technical Field

[0001] This invention relates to the field of transformer lead structure technology, specifically to a transformer lead structure and its transformer device. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change alternating current voltage. Transformers are equipped with heat sinks, and proper heat dissipation is crucial for maintaining the internal temperature within a reasonable range to ensure long-term stable operation. The insulation materials of a transformer are prone to aging and damage at high temperatures, reducing insulation performance and increasing the risk of failure. Furthermore, excessively high temperatures can lead to the deterioration of the transformer oil, further affecting the transformer's heat dissipation efficiency and overall performance. Therefore, effective heat dissipation measures are essential for the safe operation of transformers.

[0003] In addition to heat dissipation, existing transformer units typically connect the winding leads to external cables using nuts and screws. Since the transformer tank is placed on the ground and has a certain climbing height, there are certain safety hazards for workers when connecting and fixing it with tools. Therefore, it is necessary to improve the transformer lead structure. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer lead structure and a transformer device thereof to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The present invention is a transformer lead structure and transformer device thereof, including a base plate, a column and an oil tank. Six first insulating tubes are installed on the top of the oil tank, in groups of three. One group of the first insulating tubes is located outside the high voltage lead, and the other group of the first insulating tubes is located outside the low voltage lead.

[0007] The four columns are installed on the upper surface of the base plate. A connecting plate is connected between every two columns. Three second insulating tubes are installed on each of the two connecting plates. A conductive rod is provided in the middle of the second insulating tube. The top and bottom of the conductive rod extend outward from the second insulating tube, respectively.

[0008] The top of the conductive rod and the top of the first insulating tube are connected by wires, and one end of the wires is provided with a connecting component. The wires are connected to the top of the first insulating tube through the connecting component.

[0009] The outer side of the wire is covered with insulating rubber, and a connecting frame is provided on the outer wall of the insulating rubber. The three insulating rubbers are connected by the connecting frame.

[0010] A housing is rotatably connected to one end of the outer wall of the insulating rubber, and the housing is located outside the connecting assembly;

[0011] The purpose of the above setup is that the first and second insulating tubes are used to insulate the wires from the column and from the tank when the wires are connected, respectively. The insulating rubber is used to protect the outer wall of the wires and to insulate the wires from the connecting frame. The connection of one end of the wire is controlled by adjusting the connecting frame at a distance. The outer shell protects the connection point of the connecting components. The wires are quickly connected to the lead wires through the connecting components.

[0012] Furthermore, a bevel is provided on the top outer wall of the conductive rod, and a buckle is provided at one end of the wire, which is then secured to the bevel by the buckle.

[0013] The purpose of the above setup is that there is a height difference between the conductive rod on the connecting plate and the lead wire on the oil tank. The wire is connected diagonally during the connection process. The wire is secured to the diagonal cut by its own weight through the buckle, which facilitates the installation and removal of one end of the wire, thereby making it easier to maintain that end of the wire.

[0014] Furthermore, a circular hole block is provided at the top of the first insulating tube, and the connecting assembly is connected to the circular hole block;

[0015] The purpose of the above setup is to connect the round hole block to the winding lead wire, providing a quick connection method at the wire connection point.

[0016] Furthermore, the connecting component includes a U-shaped block, which is connected to the wire. A first rotating block and a second rotating block are rotatably connected to both ends of the U-shaped block, and one end of the first rotating block and the second rotating block are in contact with each other.

[0017] A torsion spring is provided at the rotational connection point between the first rotating block and the second rotating block and the U-shaped block, and the torsion spring is used for the first rotating block and the second rotating block to rotate and reset.

[0018] One end of the U-shaped block is fixedly connected to a first stop block for limiting the rotation of the first rotating block, and the inner wall of the U-shaped block is fixedly connected to a second stop block for limiting the rotation of the second rotating block.

[0019] The purpose of the above setup is that when the wire and the lead wire need to be connected to the round hole block, when the U-shaped block approaches the round hole block, the round hole block pushes and squeezes, causing the first rotating block to flip inwards towards the U-shaped block. Then the round hole block enters the interior of the U-shaped block, and the torsion spring resets the first rotating block. Due to the diagonal connection of the wire, the U-shaped block is pulled by the wire. At this time, the round hole block is located inside the rotating connection between the first rotating block and the U-shaped block.

[0020] When disassembly is required, the control connector moves the insulating rubber and wires to adjust the U-shaped block. The round hole block presses against the second rotating block, causing the second rotating block to rotate outward of the U-shaped block, thus enabling disassembly. Subsequently, the torsion spring resets the second rotating block.

[0021] Furthermore, the oil tank is installed at the bottom of two base plates, the top of the oil tank is provided with an oil inlet, the bottom of the oil tank is provided with an oil outlet, and a circulation component for circulating the oil is installed on the oil tank.

[0022] The purpose of the above configuration is that the oil inlet of the oil tank is used to fill the oil tank to dissipate heat from the windings inside the tank, and the oil outlet is used to drain the oil.

[0023] Furthermore, a number of heat sinks are installed on the outer wall of the oil tank, and a number of through holes are provided on each of the heat sinks, with the through holes of each heat sink corresponding to each other;

[0024] The purpose of the above configuration is that the heat sink is used to conduct heat to the surface of the oil tank, and the through holes in the heat sink are used to cooperate with the circulation components to dissipate heat from the oil tank.

[0025] Furthermore, the circulation assembly includes a motor, a gear oil pump, oil pipes, and a heat dissipation structure. The motor and gear oil pump are mounted on the outer wall of the oil tank. The motor drives the gear oil pump. The oil pipes are interconnected with the gear oil pump, and both ends of the oil pipes are connected to the interior of the oil tank. The oil pipes pass through through holes in the heat dissipation fins.

[0026] The purpose of the above setup is that the output shaft of the motor drives the gear oil pump to operate, and the gear oil pump circulates the oil inside the oil tank through the oil pipe. During the circulation process, it drives the heat dissipation structure to operate and further dissipate heat from the oil tank and heat sink.

[0027] Furthermore, the gear oil pump includes a pump body and two gears. The pump body is mounted on the outer wall of the oil tank, and the two gears are rotatably connected to the inner wall of the pump body and mesh with each other. The shaft of one of the gears is connected to the output shaft of the motor.

[0028] The purpose of the above setup is that the output shaft of the motor drives the drive gear to rotate. When the drive gear rotates, the teeth gradually disengage, forming a tooth-to-tooth volume. This tooth-to-tooth volume gradually increases, thereby creating a partial vacuum between the teeth, drawing liquid in from the oil inlet. As the drive gear continues to rotate, the teeth re-engage, the tooth-to-tooth volume gradually decreases, the liquid is compressed and discharged from the oil outlet, thus allowing the oil to be input and output inside the pump body and circulate inside the oil pipe.

[0029] Furthermore, the heat dissipation structure includes a closed housing, blades, and fan blades. The bottom of the closed housing is connected to the oil pipe. A rotating shaft is rotatably connected to the closed housing. Several closed housings are installed on the outer wall of the rotating shaft and are located inside the closed housing. The fan blades are installed at one end of the rotating shaft and are located outside the closed housing.

[0030] The purpose of the above setup is that, as the oil flows inside the oil pipe, the oil pushes the blades, thereby causing the shaft to rotate. The rotation of the shaft causes the fan blades to rotate, and the rotation of the fan blades accelerates the heat dissipation from the outer wall of the heat sink, thus achieving heat dissipation.

[0031] The present invention has the following beneficial effects:

[0032] (1) By setting the connecting components, there is a height difference between the conductive rod on the connecting plate and the lead wire on the oil tank. The wire is connected in a diagonal manner during the connection process. The wire is clamped on the diagonal cut by the buckle under its own weight, which makes it convenient to install and remove one end of the wire, thus making it convenient to maintain one end of the wire. When it is necessary to connect the wire and the lead wire to the round hole block, when the U-shaped block approaches the round hole block, the round hole block pushes and squeezes, causing the first rotating block to flip to the inside of the U-shaped block. Then the round hole block enters the inside of the U-shaped block, and the torsion spring resets the first rotating block. Due to the diagonal connection of the wire, the U-shaped block is pulled by the wire. At this time, the round hole block is inside the rotating connection between the first rotating block and the U-shaped block.

[0033] When disassembly is required, the control connector moves the insulating rubber and wires to adjust the U-shaped block. The round hole block presses against the second rotating block, causing the second rotating block to rotate outward of the U-shaped block, thus enabling disassembly. Subsequently, the torsion spring resets the second rotating block.

[0034] (2) Through the setting of the heat dissipation structure, the output shaft of the motor drives the drive gear to rotate. When the drive gear rotates, the teeth gradually disengage, forming a tooth volume. This tooth volume gradually increases, thereby creating a local vacuum between the teeth, drawing liquid from the oil inlet. As the drive gear continues to rotate, the teeth re-engage, the tooth volume gradually decreases, the liquid is compressed and discharged from the oil outlet, so the oil is input and output inside the pump body and circulates inside the oil pipe. During the flow of the oil inside the oil pipe, the oil pushes the blades, thereby driving the shaft to rotate. The rotation of the shaft drives the fan blades to rotate. During the rotation of the fan blades, the heat dissipation of the outer wall of the heat sink is accelerated, thereby achieving heat dissipation.

[0035] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] This invention relates to a transformer lead structure and its transformer device, such as... Figure 1 - Figure 8 As shown, it includes a base plate 1, a column 2 and an oil tank 3. Six first insulating tubes 6 are installed on the top of the oil tank 3, in groups of three. One group of first insulating tubes 6 is located outside the high voltage lead, and the other group of first insulating tubes 6 is located outside the low voltage lead.

[0049] Four columns 2 are installed on the upper surface of the base plate 1. A connecting plate is connected between every two columns 2. Three second insulating tubes 9 are installed on the two connecting plates respectively. A conductive rod 11 is provided in the middle of the second insulating tube 9. The top and bottom of the conductive rod 11 extend outward from the second insulating tube 9 respectively.

[0050] A wire 12 is connected to the top of the conductive rod 11 and the top of the first insulating tube 6. One end of the wire 12 is provided with a connecting component 13, and the wire 12 is connected to the top of the first insulating tube 6 through the connecting component 13.

[0051] The outer side of the wire 12 is covered with insulating rubber 7, and a connecting frame 8 is provided on the outer wall of the insulating rubber 7. The three insulating rubbers 7 are connected through the connecting frame 8.

[0052] A housing 10 is rotatably connected to the outer wall of one end of the insulating rubber 7, and the housing 10 is located outside the connecting assembly 13;

[0053] In this embodiment, the purpose of the above-mentioned arrangement is that the first insulating tube 6 and the second insulating tube 9 are used to insulate the wire 12 from the column 2 and from the oil tank 3 when the wire 12 is connected. The insulating rubber 7 is used to protect the outer wall of the wire 12 and to insulate the wire 12 from the connecting frame 8. The connection of one end of the wire 12 is controlled by adjusting the connecting frame 8 at a distance. The outer shell 10 protects the connection of the connecting component 13. The wire 12 is quickly connected to the lead wire through the connecting component 13.

[0054] As one implementation method, such as Figure 1 and Figure 6 As shown, going a step further:

[0055] A bevel is provided on the top outer wall of the conductive rod 11, and a buckle is provided at one end of the wire 12. The wire 12 is secured to the bevel by the buckle.

[0056] In this embodiment, the purpose of the above-mentioned arrangement is that there is a height difference between the conductive rod 11 on the connecting plate and the lead wire on the oil tank 3. The wire 12 is connected diagonally during the connection process. The wire 12 is clamped on the diagonal cut by its own weight through the buckle, which makes it convenient to install and remove one end of the wire 12, thereby facilitating the maintenance of one end of the wire 12.

[0057] As one implementation method, such as Figure 5 As shown, going a step further:

[0058] The top of the first insulating tube 6 is provided with a round hole block, and the connecting assembly 13 is connected to the round hole block;

[0059] In this embodiment, the purpose of the above-mentioned arrangement is to connect the circular hole block with the lead wire of the winding, and to provide a quick connection method at the connection point of the wire 12.

[0060] As one implementation method, such as Figure 7 - Figure 8 As shown, going a step further:

[0061] The connecting component 13 includes a U-shaped block 1301, which is connected to the wire 12. A first rotating block 1302 and a second rotating block 1303 are rotatably connected to both ends of the U-shaped block 1301, and one end of the first rotating block 1302 and the second rotating block 1303 are in contact with each other.

[0062] A torsion spring 1304 is provided at the rotational connection between the first rotating block 1302 and the second rotating block 1303 and the U-shaped block 1301, respectively. The torsion spring 1304 is used for the first rotating block 1302 and the second rotating block 1303 to rotate and reset.

[0063] One end of the U-shaped block 1301 is fixedly connected to a first stop 1305 for limiting the rotation of the first rotating block 1302, and a second stop 1306 for limiting the rotation of the second rotating block 1303 is fixedly connected to the inner wall of the U-shaped block 1301.

[0064] In this embodiment, the purpose of the above-mentioned arrangement is that when it is necessary to connect the wire 12 and the lead wire through the circular hole block, when the U-shaped block 1301 approaches the circular hole block, the circular hole block pushes and squeezes the first rotating block 1302, causing the first rotating block 1302 to flip towards the inside of the U-shaped block 1301. Then the circular hole block enters the interior of the U-shaped block 1301, and the torsion spring 1304 resets the first rotating block 1302. Since the wire 12 is connected diagonally, the U-shaped block 1301 is pulled by the wire 12. At this time, the circular hole block is located inside the rotating connection between the first rotating block 1302 and the U-shaped block 1301.

[0065] When disassembly is required, the control connecting frame 8 moves the insulating rubber 7 and the wire 12 to adjust the U-shaped block 1301. The round hole block presses the second rotating block 1303, and the second rotating block 1303 rotates to the outside of the U-shaped block 1301, thereby disassembling. Then, the torsion spring 1304 resets the second rotating block 1303.

[0066] As one implementation method, such as Figure 2 As shown, going a step further:

[0067] The oil tank 3 is installed at the bottom of the two base plates 1. The top of the oil tank 3 is provided with an oil inlet and the bottom of the oil tank 3 is provided with an oil outlet. The oil tank 3 is equipped with a circulation component 5 for circulating the oil.

[0068] In this embodiment, the purpose of the above-mentioned arrangement is that the oil inlet of the oil tank 3 is used to fill the interior of the oil tank 3 with oil to dissipate heat from the windings inside the oil tank 3, and the oil outlet is used to drain the oil.

[0069] As one implementation method, such as Figure 2 As shown, going a step further:

[0070] Several heat sinks 4 are installed on the outer wall of the oil tank 3. Several through holes are provided on each heat sink 4, and the through holes of each heat sink 4 are corresponding.

[0071] In this embodiment, the purpose of the above-mentioned arrangement is that the heat sink 4 is used to conduct heat to the surface of the oil tank 3, and the through holes of the heat sink 4 are used to cooperate with the circulation component 5 to dissipate heat from the oil tank 3.

[0072] As one implementation method, such as Figure 3 As shown, going a step further:

[0073] The circulation assembly 5 includes a motor 501, a gear oil pump 502, an oil pipe 503, and a heat dissipation structure. The motor 501 and the gear oil pump 502 are mounted on the outer wall of the oil tank 3. The motor 501 drives the gear oil pump 502. The oil pipe 503 is interconnected with the gear oil pump 502, and both ends of the oil pipe 503 are interconnected with the interior of the oil tank 3. The oil pipe 503 passes through the through holes of the heat dissipation fin 4.

[0074] In this embodiment, the purpose of the above-mentioned arrangement is that the output shaft of the motor 501 drives the gear oil pump 502 to operate, and the gear oil pump 502 circulates the oil inside the oil tank 3 through the oil pipe 503. During the circulation process, the heat dissipation structure is driven to operate to further dissipate heat from the oil tank 3 and the heat sink 4.

[0075] As one implementation method, such as Figure 3 As shown, going a step further:

[0076] The gear oil pump 502 includes a pump body and two gears. The pump body is installed on the outer wall of the oil tank 3. The two gears are rotatably connected to the inner wall of the pump body and mesh with each other. The shaft of one of the gears is connected to the output shaft of the motor 501.

[0077] In this embodiment, the purpose of the above-mentioned arrangement is that the output shaft of the motor 501 drives the drive gear to rotate. When the drive gear rotates, the teeth gradually disengage, forming an inter-tooth volume. This inter-tooth volume gradually increases, thereby creating a partial vacuum between the teeth, drawing liquid in from the oil inlet. As the drive gear continues to rotate, the teeth re-engage, the inter-tooth volume gradually decreases, the liquid is compressed and discharged from the oil outlet, so that the oil is input and output inside the pump body and circulates inside the oil pipe 503.

[0078] As one implementation method, such as Figure 3 As shown, going a step further:

[0079] The heat dissipation structure includes a closed housing 504, a blade 505, and a fan blade 506. The bottom of the closed housing 504 is connected to the oil pipe 503. A rotating shaft is rotatably connected to the closed housing 504. Several closed housings 504 are installed on the outer wall of the rotating shaft and are located inside the closed housing 504. The fan blade 506 is installed at one end of the rotating shaft and is located outside the closed housing 504.

[0080] In this embodiment, the purpose of the above-mentioned arrangement is that, during the process of the oil flowing inside the oil pipe 503, the oil pushes the blade 505, thereby driving the rotating shaft to rotate. The rotation of the rotating shaft drives the fan blade 506 to rotate. During the rotation of the fan blade 506, the heat dissipation of the outer wall of the heat sink 4 is accelerated, thereby achieving heat dissipation.

[0081] In use, the first insulating tube 6 and the second insulating tube 9 are used to insulate the wire 12 from the column 2 and from the oil tank 3 when the wire 12 is connected. The insulating rubber 7 is used to protect the outer wall of the wire 12 and to insulate the wire 12 from the connecting frame 8. The connection of one end of the wire 12 is controlled by adjusting the connecting frame 8 at a distance. The outer shell 10 protects the connection point of the connecting component 13. The wire 12 is quickly connected to the lead wire through the connecting component 13.

[0082] There is a height difference between the conductive rod 11 on the connecting plate and the lead wire on the oil tank 3. The wire 12 is connected diagonally during the connection process. The wire 12 is clamped on the diagonal cut by its own weight through the buckle, which makes it easy to install and remove one end of the wire 12, thus facilitating the maintenance of one end of the wire 12. When it is necessary to connect the wire 12 to the round hole block of the lead wire, when the U-shaped block 1301 approaches the round hole block, the round hole block pushes and squeezes the first rotating block 1302, causing the first rotating block 1302 to flip inward to the inside of the U-shaped block 1301. Then the round hole block enters the interior of the U-shaped block 1301, and the torsion spring 1304 resets the first rotating block 1302. Due to the diagonal connection of the wire 12, the U-shaped block 1301 is pulled by the wire 12. At this time, the round hole block is inside the rotating connection between the first rotating block 1302 and the U-shaped block 1301.

[0083] When disassembly is required, control the connecting frame 8 to move the insulating rubber 7 and the wire 12 to adjust the U-shaped block 1301. The round hole block presses the second rotating block 1303, and the second rotating block 1303 rotates to the outside of the U-shaped block 1301 to disassemble. Then the torsion spring 1304 resets the second rotating block 1303.

[0084] The output shaft of motor 501 drives the drive gear to rotate. When the drive gear rotates, the teeth gradually disengage, forming a tooth volume. This tooth volume gradually increases, thereby creating a partial vacuum between the teeth, which draws the liquid in from the oil inlet. As the drive gear continues to rotate, the teeth re-engage, the tooth volume gradually decreases, the liquid is compressed and discharged from the oil outlet, so that the oil is input and output inside the pump body and circulates inside the oil pipe 503.

[0085] As the oil flows inside the oil pipe 503, it pushes the blade 505, thereby causing the shaft to rotate. The rotation of the shaft causes the fan blade 506 to rotate. During the rotation of the fan blade 506, the heat dissipation from the outer wall of the heat sink 4 is accelerated, thus achieving heat dissipation.
