Description

A transformer box suitable for high dust areas

Technical field

The utility model relates to the technical field of power distribution equipment, and in particular to a transformer box suitable for areas with high dust.

Background technique

The transformer box is the box where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. In order to ensure the quality of electric energy and the safety of the equipment, voltage adjustment, power flow control and transmission are also required in the transformer box. For the protection of distribution lines and main electrical equipment, when the transformer box is working, the internal heat is high, so heat dissipation is particularly important for the transformer box. At present, a heat dissipation structure is generally installed in the transformer box. However, in some areas with high dust When the heat dissipation mechanism in the transformer box is working, it is easy to input gas containing a large amount of sand and dust from the outside into the inside of the equipment. As the sand and dust accumulate inside the transformer box, it is easy to cause short circuits and other conditions, which is harmful to the transformer box. It has huge harm. During the use of existing transformer boxes, dust screens are usually installed at the cooling fans to block external dust. When used in high dust areas, due to the large amount of dust, it is easy to cause damage to the dust screens. When cleaning the dust-proof net, it is generally necessary to disassemble and clean it. After disassembly, there is no dust-proof structure at the cooling fan, which easily causes dust to enter the transformer box. At the same time, it is troublesome to disassemble the dust-proof net and clean it. Therefore, we Launched a new transformer box suitable for areas with high dust levels.

Compared with the existing technology, the utility model has the following beneficial effects:

1. By setting up a dust-proof mechanism and installing the dust-proof frame behind the air inlet, when the transformer box is dissipated by the cooling fan, the wind is filtered by the dust-proof net and then enters the transformer box for heat dissipation. In areas with high dust, When in use, because there is more dust carried in the wind, more dust is adsorbed on the dust-proof net. By starting the cylinder, the cylinder pushes the scraper to move downward. The scraper moves downward and scrapes the dust on the dust-proof net at the same time. In addition, after the cleaning is completed, the cylinder is reset to drive the scraper into the storage tank, so that the scraper will not block the dust-proof net, and there is no need to disassemble the dust-proof net for cleaning, which can improve the dust-proof effect;
