[0002] The transformer protective cover is an auxiliary device used in power engineering to protect the transformer and maintain stable operation of the transformer. It has been widely used in the field of power equipment technology. The existing transformer protective cover is fixed to the outside of the transformer when in use to cover the transformer for protection.

[0003] Patent document CN211671774U discloses a waterproof transformer protective cover, and the protected claim "includes a cover body, a shell, a wire hole and a mounting block, the cover body is hinged on one side of the shell, the bottom end of the shell is penetrated by the wire hole, one side of the shell is provided with a mounting block, one end of the heat dissipation fan is provided with a heat dissipation hole, one end inside the cover body is penetrated by an air inlet hole, and the top of the shell is provided with a waterproof structure. The utility model is provided with a heat dissipation mechanism at one end of the shell of the transformer protective cover. When the heat dissipation fan is started, it will drive new air outside the shell to enter the inside of the shell through the heat dissipation hole, so that the air inside the shell carrying the heat generated by the transformer during operation is discharged from the gap holes at the cover body and the bottom end of the shell, thereby effectively reducing the high temperature generated by the transformer inside the shell, thereby preventing the transformer from being damaged due to excessive temperature and effectively extending the service life of the transformer."

[0022] like Figure 3 and Figure 4As shown, two groups of dust removal boxes 5 are fixedly arranged inside the shell 4, an air inlet pipe 8 is installed on the dust removal box 5, and one end of the air inlet pipe 8 extends to the outside of the shell 4, an insect-proof net 9 is embedded in the air inlet pipe 8, a first dust-proof net 6 and a second dust-proof net 7 are embedded in the dust removal box 5, and the second dust-proof net 7 is located above the first dust-proof net 6, two groups of fans 10 are fixedly arranged inside the shell 4, and the air inlet of the fan 10 extends to the inside of the dust removal box 5, a dehumidification box 11 is fixedly arranged inside the shell 4, and the air outlet of the fan 10 extends to The interior of the dehumidifier box 11 is embedded with a storage box 12 with a plurality of air holes on the surface, and a desiccant 13 is installed in the storage box 12. Two sets of tubes 14 are installed on the dehumidifier box 11, and the other ends of the tubes 14 extend to the inside of the air outlet 15. The first dustproof net 6 and the second dustproof net 7 embedded in the dust removal box 5 can filter dust in the air, and the arrangement of the two sets of dustproof nets makes the filtering effect on the air more effective. The installation of the insect-proof net 9 in the air inlet pipe 8 is used to block mosquitoes outside the shell 4, and the dry The desiccant 13 is fixedly installed in the dehumidification box 11 through the storage box 12. As the two sets of fans 10 are started, the air inlet thereof will absorb the air in the dust removal box 5, so that a negative pressure is formed inside the dust removal box 5, thereby enabling the dust removal box 5 to absorb the external air through the air inlet pipe 8. After entering the dust removal box 5, the air will be filtered through the first dustproof net 6 and the second dustproof net 7 as the fan 10 continues to absorb the air. The filtered air will be transported to the dehumidification box 11 through the fan 10. The air entering the dehumidification box 11 will be dehumidified by the desiccant 13. The desiccant 13 It can absorb excess moisture in the air to ensure the dryness of the air.

The air outlet holes 16 provided on the air outlet end 15 facing the transformer body 2 enable the air to directly blow onto the transformer body 2 after entering the protective cover to quickly cool it.

[0024] Working principle: The transformer protective cover is a protective cover body 1, which is used to protect the transformer main body 2. The first dustproof net 6 and the second dustproof net 7 embedded in the dust removal box 5 can filter the dust in the air, and the setting of the two sets of dustproof nets makes the air filtering effect more effective. The installation of the insect net 9 in the air inlet pipe 8 is used to block the mosquitoes outside the shell 4. The desiccant 13 is fixedly installed in the dehumidification box 11 through the storage box 12. With the start-up of the two sets of fans 10, the air inlet will absorb the air in the dust removal box 5 to form a negative pressure inside, so that the dust removal box 5 can absorb external air through the air inlet pipe 8. After entering the dust removal box 5, the air will be filtered through the first dustproof net 6 and the second dustproof net 7 as the fan 10 continues to absorb it. The filtered air will be transported to the In the dehumidification box 11, the air entering the dehumidification box 11 will be dehumidified by the desiccant 13. The desiccant 13 can absorb excess moisture in the air to ensure the dryness of the air. The dehumidified air will enter the air outlet 15 through the tube body 14 and enter the interior of the protective cover through the air outlet holes 16 provided on the air outlet end 15. In this way, the transformer protective cover can cool down the inside of the protective cover through clean and dry air when in use, preventing the entry of external humid air from causing oxidation and rust of metal parts inside the transformer, thereby causing short circuit or grounding fault problems, thereby improving the practicality of the transformer protective cover and extending the service life of the transformer inside it. The air outlet holes 16 provided on the air outlet end 15 directly opposite to the transformer main body 2 enable the air to be directly blown onto the transformer main body 2 after entering the interior of the protective cover to quickly cool it down.
