China's wind power industry is continuing to develop at a high speed and growing rapidly, becoming the country with the largest installed wind power capacity in the world. However, during large-scale construction, problems such as the environmental heterogeneity and complexity of wind farms and the use characteristics of electrical equipment have continued to emerge and receive attention. With the continuous increase in wind power installed capacity, the requirements for electrical equipment are getting higher and higher, and the environmental conditions are becoming more stringent. Against this background, how to improve the operating environment of the equipment has become one of the important technical research areas of wind farms.

[0003] Wind farms have a perennially humid environment and relatively harsh climatic conditions, which brings great operational problems to the cable room and box-type transformers. Under normal operating conditions, the box-type transformer has condensation and water droplets hanging on the body of the box-type transformer all year round, which will affect the service life of the equipment and even cause equipment failure or protection failure. This directly increases the workload of maintenance, operation and customer service scheduling, and increases costs. Therefore, it is necessary to improve the operating environment of the equipment to ensure the healthy operation of the equipment.

In response to the humidity problem, this project comprehensively improved the environment of the box-type transformer by strengthening the moisture removal of the cable room, improving the box structure design and manufacturing process, installing dehumidification mechanisms, and strengthening daily inspections to ensure the normal and reliable operation of the equipment.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] Embodiment: A transformer box with waterproof function, such as Figure 1-Figure 5 As shown, it includes a box body 1, a side panel 11, a back panel 12, an electric push rod 31, a hollow panel 32, an air duct 321, an exhaust fan 322, a water-absorbing cotton 33, and an electric heating strip 4; the side panel 11 is welded to the box body 1; a plurality of ventilation slots 1101 structures equidistantly distributed up and down are opened on the side panel 11; the back panel 12 is welded to the inner side of the side panel 11; the electric push rod 31 is installed in the side panel 11; the hollow panel 32 is slidably connected in the back panel 12; the telescopic end of the electric push rod 31 is fixedly connected to the hollow panel 32; the hollow panel 32 is built with a humidity sensor; the water-absorbing cotton Cotton 33; the hollow plate 32 is fixedly connected with the absorbent cotton 33; a drainage groove 1102 is provided on the lower side of the side plate 11, and the drainage groove 1102 is aligned with the inner bottom of the back plate 12; an air outlet 3201 structure is provided on the hollow plate 32; a plurality of air guide tubes 321 connected to the air outlet 3201 are fixedly connected to the hollow plate 32; all the air guide tubes 321 are commonly connected with the absorbent cotton 33; each air guide tube 321 is respectively provided with a plurality of side holes 32101 structures which are connected inside and outside; an exhaust fan 322 is installed in the air outlet 3201 of the hollow plate 32; an electric heating strip 4 is installed on the surface of the back plate 12.

[0021] like Figure 2 and Figure 3 As shown, a collecting pipe 13 is fixedly connected to the side plate 11; the collecting pipe 13 is connected to the drainage groove 1102; an interception net 2 is fixedly connected between all the ventilation grooves 1101 of the side plate 11. When impurities in the outside air flow through the ventilation groove 1101 structure with the air flow, the impurities will be intercepted by the interception net 2, so as to prevent the outside impurities from directly covering the absorbent cotton 33 and affecting the water absorption effect of the absorbent cotton 33.

[0022] When in use, the collection pipe 13 needs to be connected to an external wastewater collection device, and the outside air will flow through the interception net 2 and the absorbent cotton 33 through the ventilation slot 1101, and enter the interior of the box 1 from the air outlet 3201 of the hollow plate 32 through the air guide pipe 321 and its side hole 32101. During this process, the exhaust fan 322 performs exhaust work in the air outlet 3201 of the hollow plate 32, thereby effectively increasing the flow rate of fresh air from the outside into the interior of the box 1. During the process of the outside airflow flowing through the absorbent cotton 33, the absorbent cotton 33 can absorb the moisture contained in the airflow in time, allowing the airflow to enter the interior of the box 1 in a dry state, thereby maintaining fresh air circulation in the box 1 and ensuring a good heat dissipation effect. At the same time, the influence of humid air on the inside of the box 1 is greatly reduced, thereby ensuring the safe and stable operation of the equipment in the box 1.

[0023] When the hollow plate 32 detects that the humidity of the external air flow passing through it has increased, it means that the water absorption work of the absorbent cotton 33 is close to saturation, and the absorbent cotton 33 needs to be dried in time. First, the exhaust fan 322 stops the exhaust work, and the electric push rod 31 drives the hollow plate 32 to squeeze the absorbent cotton 33 up and down, so that the moisture in the absorbent cotton 33 is squeezed downward, and the squeezed waste water flows through the drainage trough 1102 and the collection pipe 13 into the external wastewater collection equipment. After the absorbent cotton 33 that has completed the squeezing treatment is restored upward, the electric heating strip 4 is close to the absorbent cotton 33 and performs heating and drying treatment regularly, which effectively improves the drying effect of the absorbent cotton 33 and increases the water absorption efficiency of the absorbent cotton 33 in subsequent work.

[0024] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
