[0002] The wind farm box-type substation is a compact complete set of distribution equipment designed for wind power generation systems. Its main function is to increase the low voltage generated by wind turbines to a high voltage suitable for grid-connected output, thereby realizing the power conversion and transmission of wind energy. It is a compact outdoor distribution equipment that integrates key components such as high-voltage switchgear, transformers, low-voltage distribution devices, power metering equipment and reactive power compensation devices. The box-type substation will be damp inside after long-term operation. The general dehumidification method of the box-type substation is to exhaust the internal humid air through the fan and send the external dry air in, but the fan alone cannot achieve a good dehumidification effect, and the dehumidification efficiency is not high enough.

[0045] The box body 1 is provided with a dehumidification component and a transmission component, and the transmission component is connected to the installation slot 8;

[0046] The dehumidification assembly includes a dehumidification box 2 fixedly mounted on a box body 1, a vent 211 is provided inside the box body 1, an exhaust fan 210 is installed inside the vent 211, and the vent 211 is communicated with the interior of the dehumidification box 2;

[0047] A dehumidification rack 212 is fixedly installed inside the dehumidification box 2, and a filter screen 213, a sponge pad 214 and a condenser 215 are fixedly installed inside the dehumidification rack 212; when working, when the humidity inside the box body 1 is relatively large, dehumidification can be performed through the dehumidification component, and during dehumidification, the humid air is discharged from the inside of the box body 1 through the exhaust fan 210, and then the discharged gas enters the dehumidification box 2 through the vent 211, and is then filtered by the filter screen 213, and after filtration, it is passed through the sponge pad 214 to absorb moisture, and then passes through the condenser 215 to further dehumidify the gas, and the condensed water after dehumidification by the condenser 215 is absorbed by the sponge pad 214, and the moisture is removed. The wet air drying effect is better, so the box body 1 can be better dehumidified, and at the same time, the dehumidification component drives the transmission component to work when dehumidifying, and after the transmission component works, it drives the gear rod 7 to slide inside the installation groove 8, and drives the spur gear 10 to rotate after the gear rod 7 slides. Since two closing plates 4 are arranged inside the heat dissipation groove 3, the sliding of the gear rod 7 can drive the two spur gears 10 to rotate at the same time, so that the two rotating rods 12 and the two closing plates 4 can rotate at the same time to close the heat dissipation groove 3, so that the heat dissipation groove 3 is closed when the box body 1 is dehumidified, and external air is prevented from entering the box body 1 during dehumidification, and the dehumidification effect of the dehumidification device can be better.

The dehumidified gas inside the air outlet groove 216 enters the box 1 again through the air outlet hole 217, and enters through the bottom of the box 1 when entering, so that the humid air can be squeezed to accelerate the exhaust of the humid air, thereby making the dehumidification efficiency of the dehumidification device higher.

8. A wind farm box transformer dehumidification device according to claim 7, characterized in that: The upper and lower surfaces of the slide groove (504) are provided with inner grooves (505), and the two inner grooves (505) are slidably connected with sealing plates 1 (501) and 2 (506). The opposite sides of sealing plates 1 (501) and 2 (506) are fixedly connected to the upper and lower surfaces of the slider (502), and both sealing plates 1 (501) and 2 (506) can seal the slide groove (504).

9. A wind farm box transformer dehumidification device according to claim 8, characterized in that: It also includes a water outlet component, which includes a water outlet pipe (601) fixedly installed at the bottom of the dehumidification box (2), a through hole 1 (6) is opened on the lower surface of the interior of the dehumidification frame (212), and a through hole 2 (602) is opened on the lower surface of the interior of the dehumidification box (2), and the through hole 1 (6) is communicated with the through hole 2 (602) and the interior of the water outlet pipe (601).

10. A dehumidification method for a wind farm box-type transformer dehumidification device, the method adopts the wind farm box-type transformer dehumidification device according to claim 9, characterized in that: The following steps are involved: S1. When the humidity sensor (209) detects that the humidity content in the air inside the box (1) exceeds a preset value, the controller (208) controls the exhaust fan (210) to operate; S2, when the exhaust fan (210) is in operation, the humid air inside the box (1) is discharged through the vent hole (211), and the discharged gas enters the interior of the dehumidification box (2); S3, the filter screen (213) and the sponge pad (214) in the dehumidification rack (212) inside the dehumidification box (2) filter dust and absorb moisture from the humid gas, and then the condenser (215) works to further dry and dehumidify the gas; S4, the gas after filtering, absorbing moisture and heating and drying enters the interior of the gas outlet groove (216) through the gas inlet pipe (202) and the connecting pipe (203), and enters the interior of the box (1) through the gas outlet hole (217) to squeeze the humid air inside the box (1) and accelerate the dehumidification rate; S5. The gas entering the connecting pipe (203) can also enter the inside of the cylinder (205) through the blowing pipe (204), and the piston rod (206) slides to drive the extrusion plate (207) and the gear rod (7) to move, and after the gear rod (7) moves, it drives the spur gear (10) to rotate; S6. After the spur gear (10) rotates, it drives the second rotating rod (12) and the closing plate (4) to rotate to close the heat dissipation slot (3). When the heat dissipation slot (3) is closed, the dehumidification effect is better.
