[0013] The present invention provides a transformer with a safe heat dissipation function. It has the following beneficial effects: (1) In the invention, the output shaft speed increases so that the rotation amplitude of the rotating rod increases. The rotation amplitude of the rotating rod increases so that the counterweight ball on the rotating rod collides with the counterweight ball on the vibration rod. The counterweight ball on the rotating rod collides with the counterweight ball on the vibration rod, so that the dust on the dustproof net is shaken off. The cleaning plate moves so that the dust that falls on the bottom of the protective shell is pushed into the storage box. The pressing block is pressed downward so that the dust inside the storage box is squeezed and compacted. The dust removal device collects the dust to prevent the dust from contacting the transformer and generating electric sparks to cause fire.

[0014] (2) In the present invention, the oil pump draws out the cooling oil from the transformer, and the cooling oil enters the box through the oil pipe. Impurities in the cooling oil are filtered through the filter element. After filtering, the cooling oil returns to the transformer through the oil pipe and the oil pump. Impurities in the cooling oil inside the transformer are filtered through the filter element to avoid the influence of the cooling oil on the transformer performance.

[0015] (3) This invention controls the electric push rod to move downward through a temperature sensor to rotate the long plate, which in turn drives the connecting shaft to rotate, which drives the valve to rotate, and the valve rotation allows the fire extinguishing liquid stored in the storage box to be sprayed through the nozzle to extinguish the fire. At the same time, the long plate rotates and contacts the baffle, which moves the baffle and drives the shaft to rotate. The shaft rotation drives the baffle to rotate, and the baffle rotation releases the baffle from limiting the bending rod, so that the bending rod is pulled by the spring. The bending rod moves upward and pulls the moving plate to close in the middle, thereby cutting off the air circulation between the inside and outside of the distribution cabinet, resulting in the inability of the fire extinguishing device to extinguish the fire quickly and effectively.

[0025] During operation: the motor 402 is started to drive the output shaft 403 to rotate, and the output shaft 403 rotates to drive the rotating rod 405 to rotate. The speed of the output shaft 403 increases to increase the rotation amplitude of the rotating rod 405.

The rotation of the baffle 610 releases the limit of the baffle 610 on the bending rod 605. The baffle 610 releases the limit on the bending rod 605 so that the bending rod 605 is pulled by the spring between the top plate 608 and the bending rod 605. The bending rod 605 is pulled by the spring between the top plate 608 and the bending rod 605 to rise. The rising of the bending rod 605 moves the straight rod 606. The movement of the straight rod 606 moves the movable plate 607. The movable plate 607 moves to close the dust removal device 4. The closure of the dust removal device 4 prevents the air from circulating inside the distribution cabinet 1.
