Abstract

The invention discloses a heat dissipation method for a transformation device. The heat dissipation method comprises the steps of: step 1, opening dust-proof sheets; step 2, turning on a heat dissipation fan, wherein a rotation speed of the heat dissipation fan is 1500-2500 r / min, the outer end of a blade is slidably connected with a sliding block, each sliding block can slide outwards under the action of a centrifugal force after the corresponding blade rotates, the sliding of each sliding block is bound to drive a second magnetic body, an air bag and a top plate to move outwards, the corresponding dust-proof sheet can move outwards accordingly, the upper end of a connecting rod moves outwards, the lower end of the connecting rod moves reversely so as to drive a button handle of a slide switch, and the air bag contracts to control the button handle to move reversely after the temperature is lowered, so as to reduce the rotation speed of the heat dissipation fan, and the steps are repeated to realize automatic adjustment. The heat dissipation method for the power transformation equipment can solve the problem of low heat dissipation efficiency of the existing box type transformer substation.

Description

technical field [0001] The invention relates to the technical field of substation cooling, in particular to a cooling method for substation equipment. 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 rainy weather....
