Problems solved by technology

[0002] The electrical components in the transformer electrical cabinet often generate a lot of heat due to the work of the electric load during work. The heat generated can easily cause the insulation of the transformer to age and the work efficiency to decrease. When the heat generated exceeds the heat resistance level of the transformer Finally, it is very easy to cause the transformer to be damaged due to high temperature. Therefore, the heat effect of the transformer electrical cabinet fan currently used is not good, and accidents often occur due to high temperature damage. Moreover, the transformer-related electrical components in the transformer electrical cabinet (such as control circuit boards, Air switches, terminal blocks, etc.) are placed in disorder, which affects the safety performance of the electrical cabinet
Due to the poor filtration effect of the existing electrical cabinets, the equipment in the electrical cabinets often accumulates dust, causing corrosion of the equipment and shortening the service life
[0003] Especially in areas with a lot of rainfall, the equipment in the electrical cabinet is often corroded and rusted. In severe cases, the bottom of the electrical cabinet will be submerged, which will easily affect the safety performance of the equipment and the electrical cabinet.
