Description

Technical Field

[0001] This invention relates to the field of power distribution stations, and in particular to a high-efficiency moisture-proof device for power distribution stations. Background Technology

[0002] A distribution station is a point at the end of the power grid that delivers electricity to electrical equipment or users. It connects to substations upstream and various electrical devices downstream. Generally, they have relatively small capacity and voltage levels below 35 kV. They are divided into two categories: most are used for dispatching, regulating the load on various lines; some are independent and serve to change the transmission method.

[0003] Some regions are in a monsoon climate and experience frequent humid weather such as the "return of spring" (a period of high humidity in southern China), which has a significant impact on electrical equipment, especially distribution cabinets. Currently, the moisture-proofing of distribution cabinets mainly relies on the principle of heating plates inside the cabinet. However, heating plates require power and most of them will be damaged after a period of operation. Furthermore, line faults caused by moisture are more common in humid weather, resulting in distribution cabinets in substations being frequently damaged due to moisture.

[0004] Therefore, it is necessary to propose a high-efficiency moisture-proof device for power distribution stations to solve the above problems. Summary of the Invention

The front of the nut is fixedly connected with a sealing gasket. A heat storage box is provided on one side opposite to the two first conveying pipes.

[0010] Preferably, the back sides of the tops of the two mounting posts on the front side are symmetrically provided with grooves, and a rotating handle is movably connected to the inner cavity of the groove. A first threaded post is fixedly connected to the back side of the rotating handle. The first threaded post is movably connected to the inner cavity of the front mounting post, and the back side of the first threaded post penetrates the back side of the front mounting post and is threadedly connected to the inner cavity of the back mounting post.

[0013] Preferably, a through groove is provided in the center of the bottom of the inner cavity of the outer shell, and a first heat exhaust fan is fixedly connected to the center of the bottom of the outer shell, with the bottom of the first heat exhaust fan fixedly connected to the top of the first conveying pipe.

[0014] Preferably, the back of the heat storage box is provided with an adapter groove, the size of the adapter groove and the second delivery pipe are adapted to each other, the limiting block is larger than the size of the adapter groove, the second delivery pipe is movably connected to the inner cavity of the heat storage box through the adapter groove, and the front of the sealing gasket is attached to the outside of the adapter groove.

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention provides a high-efficiency moisture-proof device for substations, which has the following beneficial effects:

[0019] 1. This high-efficiency moisture-proof device for power distribution stations, through its outer casing, can cover the heat dissipation vents of the transformer, so that the heat generated by the transformer during operation can only be input into the inner cavity of the casing. By rotating the handle, the first threaded column can be rotated, which in turn can drive the mounting column on the back to move back and forth, thereby adapting the casing to the size of the transformer for installation.

[0020] 2. This high-efficiency moisture-proof device for power distribution stations can divide the space of the second hot air chamber according to the seasonal humidity level through a partition. This allows the hot air in the second hot air chamber to be discharged into the inner cavity of the first conveying pipe more quickly after the first exhaust fan is started. By starting the servo motor, the second threaded column can be driven to rotate in the inner cavity of the movable slot. At this time, the movable block can move up and down on the outer wall of the second threaded column through the threaded slot, thereby driving the partition to move. When the partition moves, it will drive the top of the movable column to move in the inner cavity of the fixed column. At this time, the movable column and the fixed column can seal the space at the top of the second hot air chamber, so that the hot air can only be discharged into the bottom of the second hot air chamber.

[0021] 3. This high-efficiency moisture-proof device for power distribution stations can input heat into the inner cavity of the heat storage box through the first conveying pipe. When the outer shell on the back moves through the adapter groove, it will drive the first conveying pipe on the back to move. At this time, the second conveying pipe will move through the adapter groove in the inner cavity of the heat storage box. When the outer shell is completely attached to the outer wall of the transformer, the nut is rotated so that the nut can move through the thread on the outer wall of the second conveying pipe, thereby driving the sealing gasket to attach to the wall of the heat storage box and preventing excess heat from flowing out through the adapter groove.

[0022] 4. This high-efficiency moisture-proof device for power distribution stations can further heat the hot air stored in the first hot air chamber by setting a heating roller, and can discharge the hot air in the first hot air chamber through the third conveying pipe by opening the set valve and the second exhaust fan.

[0023] 5. This high-efficiency moisture-proof device for substations uses the principle of heat circulation to guide the heat energy emitted by the transformer during operation into the distribution cabinet through pipes to achieve the effect of moisture prevention. It has the advantages of heat circulation and energy saving and consumption reduction, and overcomes the problems of high energy consumption, low reliability and poor effect of heating plates in distribution cabinets. This device is simple to install and can be installed on transformers of various sizes. It can ensure sufficient heat and prevent the distribution cabinet from becoming damp and condensing.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1-6As shown, a high-efficiency moisture-proof device for a power distribution station includes a transformer 1. The transformer 1 has symmetrically arranged outer casings 2 on its front and back sides. Mounting columns 3 are symmetrically fixedly connected to the left and right sides of the top of the two outer casings 2. Partitions 11 are symmetrically arranged in the center of the inner cavity of the two outer casings 2. Movable blocks 12 are symmetrically fixedly connected to the center of the left and right sides of the two partitions 11. Threaded grooves 13 are symmetrically opened in the center of the inner cavity of the two movable blocks 12. Movable columns 10 are fixedly connected to the top of the partitions 11, and fixed columns 9 are arranged on the top of the movable columns 10. First conveying pipes 18 are symmetrically arranged at the bottom of the two outer casings 2. A second conveying pipe 19 is fixedly connected to the front of the bottom of the first conveying pipe 18 on the back side. A fixed column 9 is fixedly connected to the front of the second conveying pipe 19. The limiting block 20 and the outer wall of the second conveying pipe 19 are fixedly connected with threads 21. A nut 22 is threaded onto the outer wall of the thread 21. A sealing gasket 23 is fixedly connected to the front of the nut 22. A heat storage box 24 is provided on one side opposite to the two first conveying pipes 18. Grooves 4 are symmetrically opened on the back of the top of the two front mounting posts 3. A rotating handle 5 is movably connected to the inner cavity of the groove 4. A first threaded post 6 is fixedly connected to the back of the rotating handle 5. The first threaded post 6 is movably connected to the inner cavity of the front mounting post 3. The back of the first threaded post 6 penetrates the back of the front mounting post 3 and is threaded into the inner cavity of the back mounting post 3. Servo motors 7 are symmetrically fixedly connected to the left and right sides of the top of the outer shell 2. A second... A heat-conducting plate 8 is fixedly connected to the inner cavity of the second hot air chamber 31. A movable groove 14 is symmetrically opened in the center of the left and right sides of the inner cavity of the outer shell 2. A second threaded column 15 is rotatably connected in the inner cavity of the movable groove 14. The top of the second threaded column 15 is fixedly connected to the bottom of the servo motor 7 via a coupling. The movable block 12 and the movable groove 14 are matched in size. The movable block 12 is threadedly connected to the outer wall of the second threaded column 15 via a threaded groove 13. A fixed column 9 is fixedly connected to the top of the inner cavity of the outer shell 2. The top of the movable column 10 is movably connected to the inner cavity of the fixed column 9. A through groove 16 is opened in the center of the bottom of the inner cavity of the outer shell 2. A first row of heat fans 17 is fixedly connected in the center of the bottom of the outer shell 2. The bottom of the first row of heat fans 17... The first conveying pipe 18 is fixedly connected to the top of the heat storage box 24. The back of the heat storage box 24 is provided with an adapter groove 25. The size of the adapter groove 25 and the second conveying pipe 19 are adapted to each other. The limiting block 20 is larger than the size of the adapter groove 25. The second conveying pipe 19 is movably connected to the inner cavity of the heat storage box 24 through the adapter groove 25. The front of the sealing gasket 23 is attached to the outside of the adapter groove 25. The inner cavity of the heat storage box 24 is provided with a first hot air chamber 26. The bottom of the inner cavity of the first hot air chamber 26 is fixedly connected with a heating roller 27. There are six heating rollers 27. The third conveying pipe 28 is fixedly connected to the center of the bottom of the heat storage box 24. The outer flange of the third conveying pipe 28 is connected with a valve 29. The bottom of the third conveying pipe 28 is fixedly connected with a second exhaust fan 30.

[0033] The outer casing 2 covers the heat dissipation vents of the transformer 1, ensuring that all the heat generated by the transformer 1 during operation is directed into the inner cavity of the outer casing 2. Rotating the handle 5 rotates the first threaded post 6, which in turn moves the mounting post 3 on the back, allowing the outer casing 2 to be installed to fit the dimensions of the transformer 1. The partition 11 divides the space within the second hot air chamber 31 according to seasonal humidity levels, enabling the first exhaust fan 17 to more quickly expel the hot air from the second hot air chamber 31 into the first delivery pipe 18. The servo motor 7, when activated, drives the second threaded column 15 to rotate within the cavity of the movable slot 14. Simultaneously, the movable block 12 moves up and down along the outer wall of the second threaded column 15 via the threaded slot 13, thereby moving the partition 11. As the partition 11 moves, it causes the top of the movable column 10 to move within the cavity of the fixed column 9. At this point, the movable column 10 and the fixed column 9 seal the top space of the second hot air cavity 31, allowing hot air to only exit to the bottom of the second hot air cavity 31. Through the first conveying pipe 18, the heat is then input into the heat storage box. The heat storage box 24 is stored in its inner cavity. When the outer shell 2 moves via the adapter groove 25, it moves the first conveying pipe 18 on the back. At this time, the second conveying pipe 19 moves through the adapter groove 25 within the inner cavity of the heat storage box 24. Once the outer shell 2 is completely against the outer wall of the transformer 1, the nut 22 is rotated, allowing it to move through the thread 21 onto the outer wall of the second conveying pipe 19. This causes the sealing gasket 23 to adhere to the wall of the heat storage box 24, preventing excess heat from leaking out through the adapter groove 25. The heating roller 27 then heats the contents stored in the second conveying pipe 1. The hot air inside the first hot air chamber 26 is further heated. By opening the valve 29 and the second row of hot air fans 30, the hot air inside the first hot air chamber 26 can be discharged through the third conveying pipe 28. This device adopts the principle of heat circulation, which guides the heat energy emitted by the transformer 1 during operation to the distribution cabinet through the pipeline to achieve the effect of moisture prevention. It has the advantages of heat circulation and energy saving and consumption reduction, and overcomes the problems of high energy consumption, low reliability and poor effect of heating plates in distribution cabinets. This device is simple to set up and can be installed on transformers 1 of various sizes. It can ensure sufficient heat and prevent the distribution cabinet from becoming damp and condensing.

[0034] It should be noted that this invention is a high-efficiency moisture-proof device for a power distribution station. In use, rotating the handle 5 rotates the first threaded post 6, causing the mounting post 3 on the back to move backward, thereby moving the outer casing 2 on the back backward. The two outer casings 2 are placed at the heat dissipation vent of the transformer 1. Reversing the rotation of the handle 5 rotates the first threaded post 6, causing the mounting post 3 on the back to move forward. At this point, the two outer casings 2 can be placed against the heat dissipation vent of the transformer 1. As the outer casings 2 on the back move, the first conveying pipe 18 on the back moves, allowing the second conveying pipe 19 to move through the adapter groove 25 within the heat storage box 24. When the movement stops, rotating the nut 22 allows it to move through the thread 21 along the outer wall of the second conveying pipe 19. Rotating the nut 22 until the sealing gasket 23 is in contact with the back of the heat storage box 24 is complete. Finally, the third conveying pipe 28 is connected to the inner cavity of the distribution cabinet, depending on the weather and seasonal requirements. The position of the partition 11 is adjusted, the first threaded column 6 is activated, and the second threaded column 15 is rotated. When the second threaded column 15 rotates, the movable block 12 moves through the threaded groove 13 on its outer wall, thereby moving the partition 11 in the inner cavity of the second hot air chamber 31. When the partition 11 moves, it will drive the movable column 10 to move downward. At this time, the movable column 10 and the fixed column 9 can ensure that the top of the inner cavity of the second hot air chamber 31 is closed. When the transformer 1 is working, hot air will enter the inner cavity of the second hot air chamber 31. The first row of heat fans 17 is activated, and the hot air is driven from the through groove 16 into the inner cavity of the first conveying pipe 18. At this time, the first conveying pipe 18 will input the hot air into the inner cavity of the heat storage box 24 for storage. The heating roller 27 is activated to further heat the hot air in the inner cavity of the first hot air chamber 26. The valve 29 and the second row of heat fans 30 are opened to input the hot air into the distribution cabinet. At this time, the inside of the distribution cabinet can be moisture-proofed.
