Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, in particular to a box-type transformer with a dust removal function. Background Art

[0002] The box-type transformer concentrates the traditional transformer in a box-type housing. It has the characteristics of small size, light weight, low noise, low loss and high reliability. It is widely used in residential areas, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools and other places. The box-type transformer is a complete set of power distribution equipment, which is an organic combination of transformer, high-voltage voltage control equipment and low-voltage voltage control equipment.

[0003] In a box-type transformer device, heat dissipation mechanisms such as heat dissipation holes are usually provided in order to discharge the heat generated by the box-type transformer during operation out of the box. However, since the heat dissipation holes are connected to the outside, while the heat dissipation holes play a role in heat dissipation, they will also allow external dust to enter the box through the heat dissipation holes. These dusts will settle on the electrical components in the box, so a dust net is needed on the outer wall of the transformer. However, after a long time, a lot of dust will accumulate on the dust net, blocking the dust net, resulting in poor heat dissipation effect of the transformer. Utility Model Content

[0004] The purpose of the utility model is to provide a box-type transformer with a dust removal function in view of the defects of the prior art, so as to solve the problem that a lot of dust will accumulate on the dustproof net of the transformer after a long time, blocking the dustproof net, thereby causing poor heat dissipation effect of the transformer.

At the same time, the dust dropped by the cleaning brush can be collected, so as to prevent the dust from falling around the box and entering the box again, thereby improving the cleaning effect of the dust.

[0014] When replacing the dustproof frame, rotate the snap-in plate to release the connection between the snap-in slot and the snap-in block, hold the snap-in block to move the dustproof frame upward, so that the plug-in plate is disconnected from the plug-in slot, thereby removing the dustproof frame, and then plug the plug-in plate at the bottom of the new dustproof frame into the plug-in slot at the bottom of the heat dissipation slot, move the new dustproof frame inward, so that the mounting plate on the new dustproof frame is snapped into the mounting slot, rotate the snap-in plate so that the snap-in slot on the snap-in plate is snapped into the snap-in block, thereby completing the replacement and installation of the snap-in plate. The utility model can quickly replace and disassemble the dustproof frame, and avoid the case losing its dustproof function when the dustproof frame is disassembled, causing a large amount of dust to enter the case, so that the dust will settle on the electrical components in the case.
