When the transformer is used, the transformer 3 is positioned right above the heat dissipation device 4, the heat dissipation device 4 is used for cooling and dissipating heat for the transformer 3, the heat dissipation device 4 is started when the temperature of the transformer 3 reaches a certain temperature through temperature monitoring, and the power of the heat dissipation device 4 is regulated and controlled according to the frequency modulator after the heat dissipation device 4 is started, so that the heat dissipation device 4 can regulate the power according to the temperature, and the energy utilization is maximized.
After the heat dissipation device 4 works for a period of time, more dust is accumulated on the first dust screen 506 on the dust removal device 5, at this time, the driving motor 503 is started, the driving shaft rotates, and the first connecting plate 504 and the second connecting plate 505 are driven to rotate, so that the first dust screen 506 is driven to perform circular motion by taking the driving shaft 501 as a center.
The reservoir 509 is filled with water from the water inlet pipe 510 to the spout, and the first dust-proof net 506 moves into the reservoir 509, so that the surface of the first dust-proof net 506 is cleaned by inertia and impact force of the movement.
When the first dust screen 506 moves to the other side of the water storage tank 509, the driving motor 503 rotates reversely, so that the first dust screen 506 is impacted by water again, after multiple impacts, dust on the first dust screen 506 is cleaned, and the driving motor 503 drives the first dust screen 506 to move back to the original position.
Or the driving motor 503 rotates in the same direction all the time, so that the first dust-proof net 506 always makes a circular motion, and the dust on the first dust-proof net 506 is cleaned by continuously receiving the water flushing in the water storage tank 509.
