Description

Technical Field

[0001] The invention belongs to the technical field of power transformer cabinets, and in particular relates to a power transformer cabinet. Background Art

[0002] The distribution cabinet is mainly responsible for distributing electric energy and monitoring and controlling power lines and electrical equipment. It distributes the electric energy of a circuit of the upper-level distribution equipment to the nearest load through the distribution cabinet, and provides protection, monitoring and control for the load. According to specific uses, the distribution cabinet can be divided into power cabinets, medium and high voltage switch cabinets and transformer cabinets.

[0003] In the prior art, substations are typically installed outdoors. To adapt to the complex outdoor environment, these substations typically utilize a metal-enclosed, armored cabinet design. This protects the circuit structures installed within, such as the voltage transformer, circuit breaker, busbar, and secondary circuit. However, passive heat dissipation during operation relies solely on the cabinet's thermal conductivity, which can easily lead to localized overheating of heat-generating electrical components, compromising the safe operation of the entire substation. To address this issue, we provide a substation designed to address this issue. Summary of the Invention

[0014] The present invention has the following beneficial effects: 1. The present invention controls the operation of the power motor through the controller to rotate the reciprocating screw. During the rotation of the reciprocating screw, the air-cooling impeller rotating synchronously with it realizes the air-cooling heat dissipation inside the transformer cabinet. During the rotation of the reciprocating screw, the lifting control frame moves upward to drive the flow-pushing piston disc to slide upward along the inner wall of the hollow flow-pushing cylinder. During this process, the hollow blocking part gradually slides into the inside of the first flow pipe, so that the automatic water replenishment port enters the inside of the first flow pipe to achieve blocking. At the same time, the sealing plug moves along the horizontal guide cylinder away from the second flow pipe. The cooling water in the hollow push flow cylinder is pressurized by the upward-moving push flow piston disk, so that the cooling water flows along the second push flow tube into the horizontal guide cylinder, and flows upward along the third push flow tube, passes through the water-cooling inlet pipe and flows into the serpentine water-cooling cavity. The cooling water entering the serpentine water-cooling cavity flows through the serpentine water-cooling cavity by gravity and flows out from the water-cooling outlet pipe, thereby realizing the continuous flow of cooling water in the serpentine water-cooling cavity, so as to continuously take away the heat on the component mounting plate, thereby greatly improving the heat dissipation effect of various components mounted on the component mounting plate.

[0015] When the cam is in the state of being lowered to the bottom of the water pipe, the piston rod is moved back to the bottom of the water pipe, and the piston rod is moved back to the bottom of the water pipe, and the piston rod is moved back to the bottom of the water pipe.

[0016] 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

A first one-way valve 413 is installed on the side surface of the third flow pipe 406. Through this structural design, the air-cooling impeller 506 is driven to rotate during the rotation of the reciprocating screw 505. Under the action of the air-cooling impeller 506, the external air of the substation cabinet 102 enters the interior of the substation cabinet 102 through the air inlet net 304 and the filter cotton body, and then flows out through the exhaust pipe 411 and the exhaust hood 412, thereby realizing the flow of air in the substation cabinet 102 to improve the heat dissipation effect inside the substation cabinet 102.

[0037] In this embodiment of the present invention, the water cooling control assembly 5 also includes a power control seat 507 fixedly arranged on the second cabinet closed plate 407, the output end of the power motor 508 installed inside the power control seat 507 is connected to the reciprocating screw 505, and the reciprocating screw 505 is provided with a lifting control frame 509 that cooperates with its transmission. A vertical limit slide 414 is provided on the surface of the second installation cover 408, and the lifting control frame 509 slides with the vertical limit slide 414; the horizontal slide on the refrigeration water tank 402 The first moving rod 510 is dynamically fitted with the hollow sealing part 501, and the second moving rod 511 is horizontally slidably fitted with the sealing plug 503 on the horizontal guide tube 403. A reciprocating moving frame 512 is fixedly arranged between the first moving rod 510 and the second moving rod 511. A horizontal limiting slide 513 that slides with the second mounting seat 410 is provided on the surface of the reciprocating moving frame 512, and an elastic element 514 connected to the second mounting seat 410 is provided on the inner side of the reciprocating moving frame 512.

[0038] In the initial state, the flow piston disc 504 is against the bottom of the hollow flow cylinder 401, the hollow sealing portion 501 is slidably fitted in the first flow tube 404 and the automatic water filling port 502 is in a connected state with the refrigeration water storage tank 402, the sealing plug 503 is slidably fitted in the horizontal flow guide tube 403 and is just plugged into the second flow tube 405. At this time, the cooling water in the refrigeration water storage tank 402 automatically fills the hollow flow cylinder 401 through the automatic water filling port 502, and then the cooling water in the refrigeration water storage tank 402 is automatically filled with water through the control valve 501. The controller controls the power motor 508 to operate so that the reciprocating screw 505 rotates. During the rotation of the reciprocating screw 505, the air-cooling impeller 506 that rotates synchronously with it realizes the air cooling of the inside of the transformer cabinet 102. During the rotation of the reciprocating screw 505, the lifting control frame 509 moves upward to drive the flow piston disc 504 to slide upward along the inner wall of the hollow flow cylinder 401. In this process, the hollow blocking part 501 gradually slides into the inside of the first flow tube 404, so that the automatic The water supply port 502 enters the first flow tube 404 to achieve blocking (the cooling water in the refrigeration water storage tank 402 no longer enters the hollow flow tube 401). At the same time, the sealing plug 503 moves along the horizontal flow guide tube 403 away from the second flow tube 405. The third flow tube 406 is gradually opened. The cooling water in the hollow flow tube 401 is pressurized by the upward flow piston disk 504 so that it enters the horizontal flow guide tube 403 along the second flow tube 405 and flows along the The cooling water flows upward along the third flow pipe 406, passes through the water-cooling inlet pipe 106 and flows into the serpentine water-cooling cavity 105. The cooling water entering the serpentine water-cooling cavity 105 flows through the serpentine water-cooling cavity 105 by gravity and flows out from the water-cooling outlet pipe 107. In this way, the cooling water can continuously flow in the serpentine water-cooling cavity 105 to continuously remove the heat from the component mounting plate 101, thereby greatly improving the heat dissipation effect of the various components mounted on the component mounting plate 101.

[0039] When the lifting control frame 509 moves upward to the highest point, the reciprocating screw rod 505 continues to rotate, causing the lifting control frame 509 to start moving downward. In this process, the hollow blocking portion 501 gradually moves in the opposite direction along the inner wall of the first flow tube 404, and the sealing plug 503 moves in the opposite direction along the inner wall of the horizontal guide tube 403. When the lifting control frame 509 moves down to the lowest point, the flow-pushing piston disc 504 again rests against the bottom of the hollow flow-pushing tube 401. At this time, the hollow blocking portion 501 and the sealing plug 503 both return to their initial positions, that is, the self-closing portion 501 on the hollow blocking portion 501 is The dynamic water supply port 502 is just in a connected state with the refrigeration water storage tank 402, and the sealing plug 503 is just plugged into the second flow pipe 405. At this time, the reciprocating screw 505 stops running for a short time, so that the cooling water in the refrigeration water storage tank 402 automatically fills the hollow push flow cylinder 401 through the automatic water supply port 502. Then the controller controls the reciprocating screw 505 to start running again, and continues to realize the continuous flow of cooling water in the serpentine water-cooled cavity 105 through the up and down reciprocating motion of the push flow piston disk 504. The combination of water cooling and air cooling greatly improves the heat dissipation efficiency of the entire substation.

[0040] Specific embodiment 2, on the basis of specific embodiment 1, an inner toothed disc 515 is provided between the second cabinet sealing plate 407 and the second mounting cover 408, and a toggle control shaft 516 rotatably connected to the second mounting cover 408 is fixedly provided on the surface of the inner toothed disc 515, and a rotating toggle rod 517 is fixedly provided at one end of the toggle control shaft 516, and a force-bearing rod 518 that fits in contact with the rotating toggle rod 517 is fixedly provided on one side of the reciprocating frame 512, and a sliding rod 518 is provided inside the hollow push flow cylinder 401 to engage with the lifting control frame 5 09 is fixedly connected to the third moving rod 519, and the flow-pushing piston disc 504 is fixedly set at the bottom of the third moving rod 519; a first gear 520 is meshed in the inner cavity of the inner gear disc 515, and a linkage shaft rotatably matched with the second cabinet sealing plate 407 is fixedly set on one side of the first gear 520, and a second gear 521 is fixedly installed on the side surface of the linkage shaft, and a vertically arranged transmission rack 522 is meshed on one side of the second gear 521, and the transmission rack 522 is fixedly connected to the lifting control frame 509; Figure 10As shown, through the above-mentioned specific structural design, in the process of controlling the lifting control frame 509 to move upward, the upward-moving transmission rack 522 drives the second gear 521 to rotate counterclockwise, and the first gear 520 that rotates counterclockwise synchronously with the second gear 521 drives the inner gear plate 515 to rotate counterclockwise, thereby making the rotating toggle rod 517 rotate counterclockwise synchronously with the inner gear plate 515. During the counterclockwise rotation of the rotating toggle rod 517, a thrust is generated on the force-bearing rod 518, thereby driving the reciprocating movable frame 512 to move to the right to stretch the elastic element 514. In this process, the first moving rod 510 that moves synchronously with the reciprocating movable frame 512 drives the hollow blocking portion 501 to gradually slide into the first flow pipe 404, so that the automatic water replenishment port 502 enters the first flow pipe 404. 04 is sealed inside, and at the same time, the second moving rod 511 which moves synchronously with the reciprocating moving frame 512 drives the sealing plug 503 to move along the horizontal guide tube 403 away from the second flow pipe 405, and the third flow pipe 406 is gradually opened. When the lifting control frame 509 moves downward, the second gear 521 is driven to rotate clockwise by the downward-moving transmission rack 522, and the first gear 520 which rotates synchronously clockwise with the second gear 521 drives the inner gear disc 515 to rotate clockwise, thereby making the rotating toggle rod 517 rotate synchronously clockwise with the inner gear disc 515. In this process, the elastic restoring force of the elastic element 514 causes the reciprocating moving frame 512 to move in the opposite direction and reset, thereby ensuring that the force-bearing rod 518 is against the rotating toggle rod 517.

[0041] In this embodiment of the present invention, a third mounting seat 415 is fixedly provided on the surface of the second mounting cover 408, a return water tank 416 is fixedly installed inside the third mounting seat 415, and a vertical return pipe 417 is provided on the top of the return water tank 416. The upper end of the vertical return pipe 417 is connected and arranged on the side of the refrigeration water storage tank 402 near the top. The side of the return water tank 416 is connected and arranged on the top. A water collecting pipe 418 is provided. The water inlet end of the water collecting pipe 418 is plugged into the water-cooling outlet pipe 107. This structural design can ensure that the cooling water flowing through the serpentine water-cooling cavity 105 can be cooled by the water-cooling outlet pipe 107. The cooling water in the return water tank 416 is effectively prevented from being discharged from the collecting pipe 418 again through the collecting pipe 418, and the cooling water returns to the return water tank 416 through the collecting pipe 418. One end of the collecting pipe 418 passes through the interior of the substation cabinet 102 and a second one-way valve 419 is installed on its peripheral side surface (the second one-way valve 419 can effectively prevent the cooling water in the return water tank 416 from being discharged again through the collecting pipe 418). A return piston disk is slidingly provided inside the return water tank 416 (the return piston disk in the initial state is against the bottom of the return water tank 416), and a vertical exhaust pipe 420 is connected to the bottom of the hollow push flow cylinder 401, and a horizontal exhaust pipe 421 is connected between the vertical exhaust pipe 420 and the return water tank 416.

[0042] In this embodiment of the present invention, a first transmission wheel 422 is fixedly installed on the side surface of the reciprocating screw rod 505, a vertical transmission shaft 423 is rotatably provided on the first mounting seat 409, a second transmission wheel 424 is fixedly installed on the top of the vertical transmission shaft 423, the first transmission wheel 422 and the second transmission wheel 424 are connected by a transmission belt 425, a third gear 426 is fixedly installed on the bottom of the vertical transmission shaft 423, a support seat is fixedly provided on the surface of the second mounting cover 408, a sealing toothed disc 427 which meshes with the third gear 426 is rotatably provided on the top of the support seat, a hollow suction seat 428 connected thereto is fixedly provided at the bottom of the vertical exhaust pipe 420, the sealing toothed disc 427 is tightly fitted at the bottom of the hollow suction seat 428, an arc-shaped conducting cavity 429 is opened on the surface of the sealing toothed disc 427, and an air inlet connected to its inner cavity is opened at the bottom of the hollow suction seat 428, and the air inlet is arranged on the movement trajectory of the arc-shaped conducting cavity 429; Figure 8As shown, in the initial state, the air inlet is aligned with one end of the arc-shaped conducting cavity 429 (the air inlet is not blocked by the blocking toothed disc 427). In the process of controlling the lifting control frame 509 to move upward, the first transmission wheel 422 rotating synchronously with the reciprocating screw 505 drives the transmission belt 425 to rotate, and the second transmission wheel 424 rotating synchronously with the transmission belt 425 drives the vertical transmission shaft 423 to rotate. The third gear 426 rotating synchronously with the vertical transmission shaft 423 drives the blocking toothed disc 427 to rotate clockwise until the lifting control frame 509 moves upward to the highest point. At this time, the air inlet is aligned with the other end of the arc-shaped conducting cavity 429. (That is, the air inlet is about to be blocked by the blocking tooth plate 427), during this process, the external air is drawn into the hollow plug flow cylinder 401 along the hollow suction seat 428 and the vertical exhaust pipe 420 in sequence through the upward movement of the plug flow piston plate 504 (similar to the principle of a syringe), and then during the downward movement of the lifting control frame 509, the blocking tooth plate 427 continues to be driven by the third gear 426 to rotate clockwise until the arc-shaped conducting cavity 429 returns to its initial position. In this process, since the air inlet at the bottom of the hollow suction seat 428 is blocked by the blocking tooth plate 427, the plug flow piston plate 504 that moves downward synchronously with the lifting control frame 509 is centered The air in the air push flow cylinder 401 is pressurized, and the pressurized air enters the return water tank 416 along the horizontal exhaust pipe 421 to push the return piston disk in the return water tank 416. The cooling water in the return water tank 416 can be pressed into the refrigeration water storage tank 402 along the vertical return pipe 417 through the upward refrigeration piston disk. In this way, the cooling water can circulate between the refrigeration water storage tank 402, the serpentine water-cooling cavity 105 and the return water tank 416. When the arc-shaped conducting cavity 429 returns to its initial position, as the blocking toothed disc 427 continues to rotate clockwise (the air inlet is in an open state), the reflux piston disk automatically Under the action of body gravity, the air in the return water tank 416 is discharged along the horizontal exhaust pipe 421. When the lifting control frame 509 moves downward to the lowest point and completes the reset, the arc-shaped conducting cavity 429 returns to the initial position so that the air inlet is connected to the arc-shaped conducting cavity 429 again. At this time, the cooling water in the refrigeration water storage tank 402 automatically fills the hollow push flow cylinder 401 through the automatic water replenishment port 502. In this process, the return piston disk moves downward to push the air in the return water tank 416, so that the air therein is discharged along the horizontal exhaust pipe 421 and the hollow suction seat 428 in turn. At this time, the return piston disk is again against the bottom of the return water tank 416.
