Description

Technical Field

[0001] The invention relates to the technical field of transformer lead structures, in particular to a transformer lead structure and a transformer device thereof. Background Art

[0002] The transformer device is an electrical device that uses the principle of electromagnetic induction to change the AC voltage. At the same time, the transformer device is equipped with a corresponding heat sink. The importance of transformer heat dissipation lies in maintaining the internal temperature of the transformer within a reasonable range to ensure its long-term stable operation. The insulation material of the transformer is prone to aging and damage at high temperatures, thereby reducing the insulation performance and increasing the risk of failure. In addition, excessively high temperatures will also cause the deterioration of the transformer oil, further affecting the heat dissipation effect and overall performance of the transformer. Therefore, effective heat dissipation measures are crucial for the safe operation of the transformer.

[0003] In addition to heat dissipation, the lead wires of the windings of the existing transformer devices are usually connected to the external cables by nuts and screws. Since the oil tank of the transformer device is placed at a certain height above the ground, there are certain safety hazards when the workers use tools to connect and fix it. Therefore, it is necessary to improve the transformer lead structure. Summary of the invention

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a transformer lead structure and a transformer device thereof, comprising a bottom plate, a column and an oil tank, wherein six first insulating tubes are installed on the top of the oil tank, three in a group, wherein the first insulating tubes in one group are located outside the high-voltage lead, and the first insulating tubes in another group are located outside the low-voltage lead;

[0009] The outer side of the electric wire is covered with an insulating rubber, and the outer wall of the insulating rubber is provided with a connecting frame, and the three insulating rubbers are connected through the connecting frame;

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

[0011] The purpose of the above-mentioned arrangement is that the first insulating tube and the second insulating tube are respectively used for insulating the wires from the column and the wires from the oil tank when the wires are connected, the insulating rubber is used for protecting the outer wall of the wires and insulating the wires from the connecting frame at the same time, the connection of one end of the wire is controlled by remotely adjusting the connecting frame, the outer shell protects the connection of the connecting assembly, and the wires are quickly connected to the lead wire through the connecting assembly.

[0012] Furthermore, an oblique cutout is provided on the top outer wall of the conductive rod, and a buckle is provided at one end of the wire, and the wire is clamped on the oblique cutout through the buckle;

[0013] The purpose of the above setting is that there is a height difference between the conductive rod on the connecting plate and the lead on the fuel tank. The wires are connected diagonally during the connection process. The wires are clamped on the oblique cut through the buckle under the action of their own gravity, which facilitates the installation and disassembly of one end of the wire, thereby facilitating the maintenance of one end of the wire.

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

[0015] The purpose of the above arrangement is to connect the round hole block with the lead wire of the winding, and to provide a quick connection method for the connection of the wires.

[0016] Further, the connection assembly includes a U-shaped block, the U-shaped block is connected to the wire, and two ends of the U-shaped block are rotatably connected to a first rotating block and a second rotating block, and one end of the first rotating block and the second rotating block are in contact with each other;

[0017] Torsion springs are provided at the rotational connection points between the first rotating block and the second rotating block and the U-shaped block, respectively, and the torsion springs are used for the first rotating block and the second rotating block to perform rotational reset;

[0018] A first stopper for limiting the rotation of the first rotating block is fixedly connected to one end of the U-shaped block, and a second stopper for limiting the rotation of the second rotating block is fixedly connected to the inner wall of the U-shaped block;

[0019] The purpose of the above arrangement is that when the circular hole block for connecting the wire and the lead needs to be connected, when the U-shaped block approaches the circular hole block, the circular hole block pushes and squeezes, so that the first rotating block is turned toward the inside of the U-shaped block, and then the circular hole block enters the inside of the U-shaped block, and the torsion spring resets the first rotating block. Due to the oblique connection of the wire, the U-shaped block is pulled by the wire, and at this time the circular hole block is on the inside of the rotating connection between the first rotating block and the U-shaped block;

[0022] The purpose of the above arrangement is that the oil inlet of the oil tank is used to load oil into the interior of the oil tank to dissipate heat from the winding inside the oil tank, and the oil outlet is used to drain the oil.

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

[0025] Furthermore, the circulation component includes a motor, a gear oil pump, an oil pipe and a heat dissipation structure. The motor and the gear oil pump are installed on the outer wall of the oil tank. The motor drives the gear oil pump. The oil pipe is connected to the gear oil pump. Both ends of the oil pipe are connected to the inside of the oil tank. The oil pipe passes through the through hole of the heat sink.

[0026] The purpose of the above arrangement 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 to further dissipate heat from the oil tank and the heat sink.

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

[0028] The purpose of the above arrangement is that the output shaft of the motor drives the driving gear to rotate. When the driving gear rotates, the gear teeth gradually disengage to form an inter-tooth volume. This inter-tooth volume will gradually increase, thereby generating a local vacuum between the teeth, sucking the liquid from the oil inlet. As the driving gear continues to rotate, the gear teeth enter into meshing again, the inter-tooth volume gradually decreases, and 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.

[0029] Furthermore, the heat dissipation structure includes a closed shell, a blade and a fan blade, the bottom of the closed shell is communicated with the oil pipe, a rotating shaft is rotatably connected to the closed shell, a plurality of the closed shells are mounted on the outer wall of the rotating shaft and are located inside the closed shell, and the fan blade is mounted at one end of the rotating shaft and is located outside the closed shell;

[0030] The purpose of the above arrangement is that when the oil flows 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 from the outer wall of the heat sink is accelerated to achieve heat dissipation.

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

[0032] (1) The present invention sets a connection component so that there is a height difference between the conductive rod on the connection plate and the lead wire on the fuel tank. The wire is connected in a diagonal manner during the connection process. The wire passes through a buckle and is clamped on the oblique cutout under the action of its own gravity, which makes it convenient to install and disassemble one end of the wire, thereby facilitating the maintenance of one end of the wire. When it is necessary to connect the circular hole block of the wire and the lead wire, when the U-shaped block approaches the circular hole block, the circular hole block pushes and squeezes the first rotating block to flip toward the inside of the U-shaped block, and then the circular hole block enters the inside of the U-shaped block. 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 circular hole block is on the inner side of the rotation connection between the first rotating block and the U-shaped block.

[0033] When disassembly is required, the connecting frame is controlled to drive the insulating rubber and the wire to move, the U-shaped block is adjusted, the round hole block squeezes the second rotating block, and the second rotating block rotates toward the outside of the U-shaped block for disassembly, and then the torsion spring resets the second rotating block.

[0034] (2) The present invention sets a heat dissipation structure. The output shaft of the motor drives the driving gear to rotate. When the driving gear rotates, the gear teeth gradually disengage to form an inter-tooth volume. This inter-tooth volume will gradually increase, thereby generating a local vacuum between the teeth, sucking liquid from the oil inlet. As the driving gear continues to rotate, the gear teeth enter into meshing again, the inter-tooth volume gradually decreases, and the liquid is compressed and discharged from the oil outlet. As a result, 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 blade, thereby driving the shaft to rotate. The rotation of the shaft drives the fan blade to rotate. During the rotation of the fan blade, the heat extraction of the outer wall of the heat sink is accelerated, thereby achieving heat dissipation.

[0035] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In this embodiment, the purpose of the above arrangement is to connect the round 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 an implementation method, Figure 7 - Figure 8 As shown, further:

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

[0062] Torsion springs 1304 are provided at the rotational connection points between the first rotating block 1302 and the second rotating block 1303 and the U-shaped block 1301, respectively, and the torsion springs 1304 are used for the first rotating block 1302 and the second rotating block 1303 to perform rotational reset;

[0064] In the present embodiment, the purpose of the above arrangement is that when the electric wire 12 needs to be connected to the circular hole block of the lead wire, when the U-shaped block 1301 approaches the circular hole block, the circular hole block pushes and squeezes the first rotating block 1302, so that the first rotating block 1302 is flipped toward the inside of the U-shaped block 1301, and then the circular hole block enters the inside of the U-shaped block 1301, and the torsion spring 1304 resets the first rotating block 1302. Due to the oblique connection of the electric wire 12, the U-shaped block 1301 is pulled by the electric wire 12, and at this time the circular hole block is on the inner side of the rotation connection between the first rotating block 1302 and the U-shaped block 1301;

[0065] When disassembly is required, the connecting frame 8 is controlled to drive the insulating rubber 7 and the wire 12 to move, the U-shaped block 1301 is adjusted, the round hole block squeezes the second rotating block 1303, and the second rotating block 1303 rotates to the outside of the U-shaped block 1301 for disassembly, and then the torsion spring 1304 resets the second rotating block 1303.

[0066] As an implementation method, Figure 2 As shown, further:

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

[0069] As an implementation method, Figure 2 As shown, further:

[0070] A plurality of heat sinks 4 are mounted on the outer wall of the oil tank 3, and a plurality of through holes are respectively arranged on the plurality of heat sinks 4, and the through holes of each heat sink 4 correspond to each other;

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

[0072] As an implementation method, Figure 3 As shown, further:

[0073] The circulation component 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 installed on the outer wall of the oil tank 3. The motor 501 drives the gear oil pump 502. The oil pipe 503 is connected to the gear oil pump 502. Both ends of the oil pipe 503 are connected to the inside of the oil tank 3. The oil pipe 503 passes through the through hole of the heat sink 4.

[0074] In this embodiment, the purpose of the above-mentioned setting 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 an implementation method, Figure 3 As shown, further:

[0076] The gear oil pump 502 includes a pump body and two gears. The pump body is mounted 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 rotating 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 driving gear to rotate. When the driving gear rotates, the gear teeth gradually disengage to form an inter-tooth volume. This inter-tooth volume will gradually increase, thereby generating a local vacuum between the teeth, sucking the liquid from the oil inlet. As the driving gear continues to rotate, the gear teeth enter into meshing again, the inter-tooth volume gradually decreases, and the liquid is compressed and discharged from the oil outlet, so that the oil body is input and output inside the pump body and circulates inside the oil pipe 503.

[0078] As an implementation method, Figure 3 As shown, further:

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

[0080] In this embodiment, the purpose of the above-mentioned setting is that when the oil flows inside the oil pipe 503, the oil pushes the blade 505, thereby driving the rotating shaft to rotate, and the rotation of the rotating shaft drives the fan blade 506 to rotate. During the rotation of the fan blade 506, the heat extraction from the outer wall of the heat sink 4 is accelerated, thereby achieving heat dissipation.

[0081] When 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 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 remotely. The housing 10 protects the connection of the connecting assembly 13. The wire 12 is quickly connected to the lead wire through the connecting assembly 13.

[0082] There is a height difference between the conductive rod 11 on the connecting plate and the lead wire on the fuel tank 3. The wire 12 is connected in a diagonal manner during the connection process. The wire 12 is clamped on the oblique incision through the buckle ring under the action of its own gravity, which makes it convenient to install and disassemble one end of the wire 12, thereby facilitating the maintenance of one end of the wire 12. When it is necessary to connect the wire 12 with the circular hole block of the lead wire, when the U-shaped block 1301 is close to the circular hole block, the circular hole block pushes and squeezes the first rotating block 1302, so that the first rotating block 1302 is flipped toward the inner side of the U-shaped block 1301, and 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 in a diagonal manner, the U-shaped block 1301 is pulled by the wire 12. At this time, the circular hole block is on the inner side of the rotation connection between the first rotating block 1302 and the U-shaped block 1301.

[0083] When disassembly is required, the connecting frame 8 is controlled to drive the insulating rubber 7 and the wire 12 to move, the U-shaped block 1301 is adjusted, the round hole block squeezes the second rotating block 1303, and the second rotating block 1303 rotates to the outside of the U-shaped block 1301, so as to be disassembled, and then the torsion spring 1304 resets the second rotating block 1303;

[0084] The output shaft of the motor 501 drives the driving gear to rotate. When the driving gear rotates, the gear teeth gradually disengage, forming an inter-tooth volume. This inter-tooth volume will gradually increase, thereby generating a local vacuum between the teeth, sucking the liquid from the oil inlet. As the driving gear continues to rotate, the gear teeth enter into meshing again, the inter-tooth volume gradually decreases, and 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, the oil pushes the blade 505, thereby driving the shaft to rotate. The rotation of the shaft drives the fan blade 506 to rotate. During the rotation of the fan blade 506, the heat extraction from the outer wall of the heat sink 4 is accelerated, thereby achieving heat dissipation.
