Problems solved by technology

[0002] With the maturity of my country's electric power technology, various electric power equipment develops rapidly. Power transformer is a common structure, which is mainly installed outdoors. Invasion, the traditional technology mainly uses heat dissipation windows to dissipate heat, but its waterproofness is limited. At the same time, when used for a long time, the heat dissipation windows will absorb a lot of dust, which will also affect the heat dissipation performance. Therefore, manual cleaning is required at regular intervals, which is not only time-consuming and laborious, but also It is also easy to damage the transformer, so the applicability and practicality are limited

Embodiment 1

[0021] Such as figure 1 The shown intelligent heat dissipation dust cover for transformers includes a cover body 1, on which the installation and fixing lugs 2 are arranged, and on the side wall of the cover body 1, heat dissipation holes 3 are arranged, A T-shaped air guide pipe 4 is arranged inside the cover body 1, and the vertical pipe of the T-shaped air guide pipe 4 communicates with the heat dissipation hole 3, and at both ends of the horizontal pipe of the T-shaped air guide pipe 4 All are provided with cooling blower fan 5, be provided with baffle plate 6 at the horizontal tube center of described T-shaped air guide pipe 4, the top of described baffle plate 6 is connected on the horizontal tube of T-shaped air guide tube 4 by rotating shaft 7 and The bottom end of the baffle plate 6 is movable on both sides of the vertical pipe opening of the T-shaped air guide pipe 4 under the action of the two cooling fans 5, and at least two A dust shield 8 is provided with a smal...

Embodiment 2

[0028] During work, based on the structural basis of Embodiment 1, the following steps are included: the temperature sensor detects that the preset value is exceeded in the cover body 1, and the information is sent to the controller, and the controller controls the heat dissipation at one end of the T-shaped air duct 4 horizontal tubes The fan 5 works, the cold air enters the cover body 1 from the air inlet channel 16, and the baffle 6 rotates along the rotating shaft 7; the hot air is discharged from the cooling hole 3; after a period of time, the controller controls the switching switch 14 to switch the T-shaped air guide The cooling fan 5 at the other end of the tube 4 and the horizontal tube works, and the above process is repeated to realize that the two cooling fans 5 work alternately. At the same time, the controller controls the dust removal fan 18 to work, and the cold air blows through the air nozzle 19 to remove dust, effectively ensuring the cleanliness of the cold ...

Abstract

The invention discloses an intelligent heat dissipation dust cover for transformers and a working method thereof. Heat dissipation holes are arranged in the side wall of a cover body, and a T-shaped air guide tube is arranged inside the cover body. A vertical tube of the T-shaped air guide tube is communicated with the heat dissipation holes. Cooling fans are arranged on both ends of the horizontal tube of the T-shaped air guide tube. A baffle is arranged at the center of the horizontal tube of the T-shaped air guide tube. The top of the baffle is connected with the horizontal tube of the T-shaped air guide tube through a rotating shaft. At least two dust blocking plates are arranged on the inner wall of the vertical tube of the T-shaped air guide tube. A small motor is arranged on the outer wall of the T-shaped air guide tube. The main shaft of the small motor passes through the side wall of the T-shaped guide tube and is connected with the dust blocking plates. A temperature sensor and a controller are arranged in the cover body. The controller is electrically connected with the temperature sensor, the cooling fans and the small motor. The intelligent heat dissipation dust coverfor the transformers has reasonable structure arrangement, high automatic and intelligent degree, good water resistance, good use stability, and strong applicability and practicality.
