Description

An outdoor box-type transformer device

technical field

The invention relates to a transformer device, in particular to a box-type transformer comprising a box body and a transformer body.

Background technique

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;

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;

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. Installing 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.

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.

Preferably, as shown in Figure 7: the exhaust assembly also includes a case cover sound-absorbing assembly, and the case-cover sound-absorbing assembly includes a sound-absorbing assembly with the same structure as the sound-absorbing ventilation assembly and a flat sound-absorbing assembly arranged at the center above the sound-absorbing assembly Plate 606, the corrugated sound-absorbing plate 607 is installed symmetrically on both sides of the flat sound-absorbing plate; the exhaust fan frame 608 is fixedly installed above the flat sound-absorbing plate and the corrugated sound-absorbing plate, and the exhaust fan 609 is fixed in the exhaust fan frame, and the lower bracket is arranged above the exhaust fan frame, and the lower bracket includes The lower card frame 613, the bracket frame 612 and the upper card frame 611, the filter dustproof plate 610 is installed on the lower card frame, the bracket frame is installed on the lower card frame, the upper card frame is fixed on the bracket frame, and the electric support rod is fixedly installed on the upper card frame. On the card frame; the edges of the upper card frame and the lower card frame are located outside the frame of the bracket, and a mounting hole is opened on the case cover, and the upper card frame and the lower card frame are clamped and fixed on the upper surface and the lower surface of the mounting hole respectively. In this embodiment, a sound-absorbing structure with better effect is designed for the exhaust assembly, because the opening of the exhaust assembly is relatively large. In addition, the sound-absorbing structure at the position of the air inlet assembly and the air outlet assembly is designed so as not to increase the thickness of the box. ; This embodiment makes full use of the advantages of the higher height of the exhaust assembly, designs a basic sound-absorbing structure, and then on the basis of the sound-absorbing structure, through the cooperation of the flat sound-absorbing plate and the corrugated sound-absorbing plate, the air flow channel can be increased, so that not only Better sound absorption can also ensure smooth ventilation. This embodiment also uses the design of the exhaust fan to make the exhaust component an active exhaust to improve the exhaust effect. It can be turned on when the heat conduction effect of the air outlet is not good, which not only saves energy but also ensures the heat dissipation effect. What needs to be explained about temperature measurement and heat dissipation The starting timing can be the existing basic control structure and control method, which is not the core improvement point of the present invention, and will not be repeated here. The upper clamping frame and the lower clamping frame of this embodiment realize the reliable fixing of the exhaust assembly at the position of the box cover, which is helpful for reliable installation and waterproofing. The part of the clamping frame beyond the frame will cover the installation hole, providing installation space and Rainproof effect.

Preferably: both the flat sound-absorbing board and the corrugated sound-absorbing board have a three-layer structure, including a galvanized steel plate layer in the middle and glass wool layers on both sides; the sound-absorbing parts are made of glass wool. The present invention not only designs a structure that is more conducive to sound attenuation, but also designs sound-absorbing materials on the material, so the sound-absorbing (or sound-absorbing) effect is very good.
