At this time, the elastic support plate 445 and the second spring 447 work together to further absorb and convert the impact force to achieve a multi-stage buffer effect.

One side of 37 is fixed to the side of the adjacent guide support plate 236, and the outside air is guided into the outer cylinder 211 by the air guide fan 214, and the dust impurities in the air are filtered out by the dust screen 212, and the clean air is introduced into the gathering box 231 in cooperation with the air collecting cylinder 213 and the connecting pipe 215. The inclined air supply plate 233 is set to make the air circulate in the gathering box 231, and the slow flow groove 234 is set to achieve temporary retention of air flow, so that the air overflows through the air guide groove 235, thereby expanding the discharge area of ​​the air in the gathering box 231, and utilizing the flow guidance of the guide support plate 236 and the impact of the air on the swing plate 237 to make the swing plate 237 swing and compress the elastic plate 238 to deform, so that the air can circulate in multiple directions, further expanding the flow range of the air in the transformer housing 1, thereby improving the heat dissipation efficiency of the dry-type transformer.

[0027] During operation, outside air enters the outer cylinder 211 through the dust screen 212. The dust screen 212 effectively blocks dust and impurities, ensuring the cleanliness of the air entering the transformer housing 1. The air guide fan 214 rotates in the outer cylinder 211 to generate negative pressure and accelerate the air flow. After the air is sucked in, it is accelerated by the air guide fan 214 and enters the air collecting cylinder 213 and is collected. The air in the air collecting cylinder 213 is transported to the transfer tube 232 through the connecting pipe 215 and enters the collecting box 231. In the collecting box 231, the air first encounters the inclined air supply plate 2 33. The inclined design enables the air to flow along the slow flow groove 234 and be dispersed in all directions through the air guide groove 235. The design of the slow flow groove 234 and the air guide groove 235 gradually slows down the air speed during the flow process, increasing the contact time and area between the air and the dry-type transformer body 3, thereby improving the heat dissipation efficiency. The setting of the guide support plate 236 and the swing plate 237 further guides the air flow direction, ensuring that the air can evenly cover all parts of the transformer housing 1. Finally, the heat-dissipated air is discharged from the transformer housing 1 to complete the heat dissipation operation.

[0028] The following is a detailed description of the working principle of this energy-saving dry-type transformer with vibration isolation function.

[0029] During use, when the dry-type transformer body 3 is running, the vibration force generated is first received by the supporting groove plate 411, and the supporting groove plate 411 makes elastic contact with the bottom surface of the inner cavity of the transformer housing 1 through the rubber pad 416 and the cross rubber plate 417 at the bottom thereof, thereby preliminarily absorbing and dispersing the vibration force. The connecting cross plate 431 forms a stable connection structure with the supporting groove plate 411 and the inner wall of the transformer housing 1 through the elastic support plate 435 and the limiting claw plate 432 on the fixing plate 433. When the vibration force is transmitted to the connecting cross plate 431, the elastic support plate 435 is deformed to further absorb and convert the vibration force. At the same time, the limiting claw plate 432 slides in the snap plate 434 to ensure the stability of the connection and the vibration isolation effect. As a result, the sliding cone block 421 moves up and down with the vibration of the connecting cross plate 431, compressing or stretching the first spring 422. The elastic deformation of the first spring 422 further absorbs and converts the vibration force, reducing the impact of the vibration on the transformer housing 1 and the surrounding environment. The bottom surface of the support plate 441 is fixed to the top of the dry-type transformer body 3, providing a stable support foundation for the entire anti-collision component. The elastic anti-collision plate 442 is directly in contact with the top of the inner cavity of the transformer housing 1. When the transformer vibrates, the elastic anti-collision plate 442 first absorbs and disperses the impact force, reducing the direct impact of the impact on the transformer body. A multi-stage buffer is formed between the top plate 446 and the cushion seat 444 through the elastic support plate 445 and the second spring 447. Structure, when the elastic anti-collision plate 442 is impacted and deformed, the impact force will be further transmitted to the top plate 446, and the elastic support plate 445 and the second spring 447 will work together to further absorb and convert the impact force, thereby achieving a multi-stage buffering effect. Then, the outside air enters the outer cylinder 211 through the dust-proof mesh plate 212, and the dust-proof mesh plate 212 effectively blocks dust and impurities, thereby ensuring the cleanliness of the air entering the transformer housing 1. The air guide fan 214 rotates in the outer cylinder 211 to generate negative pressure and accelerate the air flow. After the air is inhaled, it is accelerated by the air guide fan 214 and enters the air collecting cylinder 213 and is gathered. The air in the air collecting cylinder 213 is transported to the transfer pipe 2 through the connecting pipe 215. 32, and enters the gathering box 231. In the gathering box 231, the air first encounters the inclined air delivery plate 233. The inclined design allows the air to flow along the slow flow groove 234 and be dispersed in all directions through the air guide groove 235. The design of the slow flow groove 234 and the air guide groove 235 allows the air speed to gradually slow down during the flow process, increasing the contact time and area between the air and the dry-type transformer body 3, thereby improving the heat dissipation efficiency. The setting of the guide support plate 236 and the swing plate 237 further guides the air flow direction to ensure that the air can evenly cover all parts of the transformer housing 1. Finally, the air that has been cooled is discharged from the transformer housing 1, completing the heat dissipation operation and maintaining the stable operation of the transformer.
