Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a dry-type transformer with moisture-proof internal circulation and convenient heat dissipation. Background Art

[0002] A dry-type transformer is a transformer that uses dry insulating materials (such as resin) as the insulating medium instead of liquid insulating media (such as oil).

[0003] However, the traditional dry-type transformer does not have moisture-proof components inside, which is prone to problems such as electric leakage, sparking and corrosion of the transformer, greatly shortening the service life of the dry-type transformer. Moreover, if the heat dissipation and cooling operation of the transformer cannot be carried out at any time, problems such as overheating of internal components, reduced efficiency or damage may occur. Therefore, a dry-type transformer with moisture-proof internal circulation and convenient heat dissipation is needed to solve the above technical problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a dry-type transformer with moisture-proof internal circulation and convenient heat dissipation, which can effectively solve the technical problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A dry-type transformer with moisture-proof internal circulation and convenient heat dissipation includes a box body. A water tank is fixedly connected to the outer wall of the box body. The interior of the box body is divided into a dehumidification chamber and a heat dissipation chamber by a U-shaped block. Two groups of water pipes surrounding the inner wall of the heat dissipation chamber are fixedly connected to the water tank. The end of the water pipe is fixedly connected to a cooler fixed on the inner wall of the heat dissipation chamber. The bottom of the cooler extends with a water outlet pipe communicated with the water tank. A drain pipe is fixedly connected to the water tank, and a ball valve is fixedly arranged on the drain pipe.

[0007] As a further scheme of the utility model, fixing blocks with slots are symmetrically fixed on the outer side walls of both sides of the water tank. Plug blocks are inserted into the slots, and an arc-shaped filter screen is fixedly connected between the two side plug blocks. The top of the water tank is in a fan shape that fits the radian of the arc-shaped filter screen.

[0008] As a further scheme of the utility model, an air outlet is opened on the top surface of the U-shaped block. A servo motor is fixed on the top wall of the dehumidification chamber. A rotating shaft is fixedly connected to the servo motor, and multiple groups of fan blades are fixedly connected to the rotating shaft.

[0009] As a further scheme of the utility model, threaded rods are rotatably connected to the top walls on both sides of the servo motor in the dehumidification chamber. Threaded sleeves are threadedly connected to the threaded rods, and the threaded sleeves are located inside a grid box for placing activated carbon.

[0010] As a further solution of the utility model, a humidity monitor is fixed on the inner wall of the heat dissipation cavity, and the humidity monitor is connected to the threaded rod signal.

[0011] As a further solution of the utility model, heat dissipation holes leading to the outside of the box body are opened on the inner walls on both sides of the dehumidification chamber, and a rain shield is fixed on the top surface of the box body.

[0012] As a further solution of the utility model, the grid box is located above the heat dissipation holes when the humidity is normal, and the grid box covers the heat dissipation holes when the humidity exceeds the standard.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The water tank continuously delivers cold water to the water pipe to absorb the heat in the heat dissipation cavity. After absorbing the heat, the hot water enters the cooling machine for cooling and then flows back to the water tank, thus realizing the reuse of water resources. In rainy days, rainwater enters the water tank through the arc filter, while debris is blocked out. The arc surface of the arc filter can prevent debris from staying.

[0015] 2. The servo motor drives the shaft to drive the fan blades to rotate and absorb heat into the dehumidification chamber through the air outlet. When the hot air passes through the grid box, the activated carbon inside is dried to reduce the internal humidity and then discharged through the heat dissipation holes. When the humidity monitor detects that the humidity is too high, the threaded rod rotates to move the grid box to cover the heat dissipation holes, absorbing the moisture in the air entering the box from the outside, and the grid box returns to its position when the humidity returns to normal.

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] As Figure 1-5 shown, a dry-type transformer with moisture-proof internal circulation and easy heat dissipation includes a box body 1. A water tank 2 is fixedly connected to the outer wall of the box body 1. The inside of the box body 1 is divided into a dehumidification chamber 4 and a heat dissipation chamber 5 by a C-shaped block 3. Two groups of water delivery pipes 6 that surround the inner wall of the heat dissipation chamber 5 for one week are fixedly connected to the water tank 2. The end of the water delivery pipe 6 is fixedly connected to a chiller 7 fixed on the inner wall of the heat dissipation chamber 5. A water outlet pipe 8 extends from the bottom of the chiller 7 and communicates with the water tank 2. A drain pipe 9 is fixedly connected to the water tank 2. A ball valve 10 is fixedly provided on the drain pipe 9. The ball valve 10 can control the opening and closing of the drain pipe 9 to drain or store water. The water delivery pipe 6 surrounding the inner wall for one week can contact the hot air in the heat dissipation chamber 5 more fully.

[0024] In this embodiment, fixed blocks 12 with slots 11 are symmetrically fixed on the outer side walls of the water tank 2. Insert blocks 13 are inserted into the slots 11, and an arc-shaped filter screen 14 is fixedly connected between the two side insert blocks 13. The top of the water tank 2 is in a fan shape that fits the arc of the arc-shaped filter screen 14. While the arc-shaped filter screen 14 allows rainwater to pass through, the arc surface can prevent sundries from staying on it, and it is more convenient to remove and replace due to the plug-in connection.

[0025] In this embodiment, an air outlet 15 is opened on the top surface of the C-shaped block 3. A servo motor 16 is fixed on the top wall of the dehumidification chamber 4. A rotating shaft 17 is fixedly connected to the servo motor 16. Multiple groups of fan blades 18 are fixedly connected to the rotating shaft 17. When the servo motor 16 drives the rotating shaft 17 to rotate, the fan blades 18 can rotate to suck hot air into the dehumidification chamber 4 through the air outlet 15.

[0026] In this embodiment, threaded rods 19 are rotatably connected to the top walls on both sides of the servo motor 16 in the dehumidification chamber 4. Threaded sleeves 20 are threadedly connected to the threaded rods 19. The threaded sleeves 20 are located inside a grid box 21 for placing activated carbon. The threaded sleeves 20 can move when the threaded rods 19 rotate to adjust the position of the grid box 21.

[0027] In this embodiment, a humidity monitor 22 is fixed on the inner wall of the heat dissipation cavity 5, and the humidity monitor 22 is connected to the threaded rod 19 by signal. When the humidity monitor 22 detects that the humidity exceeds the standard or returns to normal, the threaded rod 19 rotates, thereby adjusting the position of the grid box 21.

[0028] In this embodiment, heat dissipation holes 23 leading to the outside of the box body 1 are opened on the inner walls on both sides of the dehumidification chamber 4, and a rain shield 24 is fixed on the top surface of the box body 1. The rain shield 24 extends out of both sides of the box body 1 to prevent rainwater from falling directly into the heat dissipation holes 23.

[0029] In this embodiment, the grid box 21 is located above the heat dissipation holes 23 when the humidity is normal, and covers the heat dissipation holes 23 when the humidity exceeds the standard. When the humidity exceeds the standard, external humid air enters the box body 1, and the grid box 21 covers the heat dissipation holes 23 to directly process the air entering the box body 1.

[0030] It should be noted that the utility model is a moisture-proof internal circulation dry-type transformer for easy heat dissipation. When in use, the water tank 2 continuously transports cold water into the water pipe 6 to absorb the heat in the heat dissipation chamber 5. The hot water after absorbing the heat enters the cooling machine 7 for cooling and then flows back to the water tank 2, thereby realizing the reuse of water resources. In rainy days, rainwater enters the water tank 2 through the arc filter 14, and debris is blocked outside. The arc surface of the arc filter 14 can prevent debris from staying. The servo motor 16 drives the rotating shaft 17 to drive the fan blades 18 to rotate and absorb heat into the dehumidification chamber 4 through the air outlet 15. When the hot air passes through the grid box 21, the internal activated carbon is dried to reduce the internal humidity and then discharged through the heat dissipation holes 23. When the humidity monitor 22 detects that the humidity is too high, the threaded rod 19 rotates to move the grid box 21 to cover the heat dissipation holes 23, absorb the moisture in the air entering the box body 1 from the outside, and return the grid box 21 to its original position when the humidity returns to normal.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
