Embodiment

[0026] Basic as attached figure 1 As shown, the heat dissipation device of the substation includes a frame, and also includes cooling holes arranged on the frame. A cooling fan and a dust-proof sheet for adjusting the working area of ​​the cooling hole are sequentially arranged in the cooling hole along the axial direction. The cooling fan includes Rotate the rotating shaft arranged on the frame, the blade fixedly connected with the rotating shaft, slide the sliding block arranged on the outer end of the blade, a tension spring is arranged between the inner end of the sliding block and the blade, and the first magnetic body is fixed on the outer end of the sliding block; heat dissipation A second magnetic body is slidably arranged on the outer wall of the hole, and a top plate is also fixed on the second magnetic body, and an air bag is also fixed between the top plate and the second magnetic body. The second magnetic body and the first magnetic body are mutually repulsive. Th...

Abstract

The invention discloses a heat dissipation method for a transformer station, and the method comprises the following steps: 1, starting a dustproof piece; 2, starting a cooling fan, wherein the rotating speed of the cooling fan is 1000-2800 r / min. An outer end of a blade is slidingly connected with a sliding block, and the sliding block can slide outwards under the action of a centrifugal force after the blade rotates. The sliding of the sliding block inevitably drives a second magnet, an air bag and a top plate to move outwards, and the dustproof piece also can move outwards, and the upper endof a connecting rod moves upwards. The lower ends of the connecting rod moves in a reverse direction, thereby driving a torsion handle of a sliding switch to move. After the temperature decreases, the air bag shrinks to control the torsion handle to move in a reverse direction, thereby reducing the rotating speed of the cooling fan. The above operations are carried out in a looped manner, therebyachieving the automatic adjustment. The method can solve a problem that a conventional box-type transformer substation is low in heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of substation heat dissipation, in particular to a heat dissipation method for a substation. Background technique [0002] Box-type substations are generally equipped with a lot of high and low-voltage power distribution equipment. These power distribution equipment generate a lot of heat. Therefore, box-type substations must have strong heat dissipation capabilities and good protection performance to prevent small animals from entering. [0003] In order to meet the waterproof and anti-foreign object requirements of the box-type substation, the shell structure of the box-type substation in the prior art is mostly a sealed design, and the heat dissipation performance is very poor, or the shell of the box-type substation is equipped with flat heat dissipation windows, but due to The structural defects of the flat heat dissipation window itself are poor waterproof, and it is easy to enter water in extreme rain...
