Problems solved by technology

[0002] At present, in the field of power transmission and transformation, the most used type of transformer is a box-type transformer, which includes a box body, which organizes the transformer body inside, and the box body provides protection, installation and heat dissipation functions; specifically, the box body is equipped with shutters or convection Holes are used to realize the heat dissipation function, and prefabricated foundations such as rafts are set inside the box to fix the transformer body; after a long period of use, we found that the design efficiency of the existing convection holes in the box is very low, and the heat inside the box rises evenly. Concentrated on the top, the convection holes set on the side of the box are difficult to completely replace the internal hot air; if the heat dissipation holes are opened on the box cover on the top of the box, although the hot air can be discharged quickly, a large part of the box-type transformers are set in Outdoors, this structure greatly increases the possibility of internal water ingress, causing damage to the device;

[0003] In the process of researching the heat dissipation technology of box-type transformers, we found that inside the box, heat sinks are installed on the surface of the transformer body to improve the heat dissipation capacity, but a large amount of heat emitted by the heat sinks accumulates inside the box, and the current natural heat dissipation is difficult. Exhaust, even if a fan is installed to extract the internal hot air, the heat exhaust effect is poor due to the single exhaust direction of the fan extraction position, and there are too many internal dead angles that cannot reliably dissipate heat;

[0004] In addition, the transformer device will vibrate when it is in use. The vibration is currently realized by the shock-absorbing rubber installed at the bottom. However, after our research, we found that the vibration direction is not only the vertical vibration, but also the horizontal vibration. Setting shock-absorbing rubber at the bottom will cause the vibration in the horizontal direction to not be suppressed, and the vibration damage will increase over time, causing the transformer to fail to work normally

[0005] Finally, whether it is an indoor or outdoor box-type transformer, the opening of the heat dissipation holes will cause an increase in internal noise and airflow noise, which will affect the work and life of people in the installation location; only by controlling noise can the popularity of box-type transformers go further , the scope of application will be greatly increased
