Description

A box-type transformer with a ventilation system

technical field

The utility model relates to the technical field of box-type transformers, in particular to a box-type transformer with a ventilation system.

Background technique

As a complete set of power distribution equipment, box-type transformers are organically combined with transformers, high-voltage voltage control equipment, and low-voltage voltage control equipment. The basic principle is that through the pressure start system, armored wire, fully automatic system of substation, DC point and corresponding technical equipment, reasonable assembly is carried out according to the specified sequence, and all components are installed to a specific waterproof, dustproof and anti-static. A specific transformer is formed in a completely sealed tempered box structure such as a rat.

The problem of heat dissipation is one of the main problems existing in the existing box-type substation, and the related problems are also the problems of ventilation and dust prevention. The three problems affect and restrict each other. The temperature rise is caused by the heat generated by solar radiant heat passing through the box body, transformers and compensation capacitors in the box. If the temperature rise in the box is too high, it will affect the normal operation of high and low voltage equipment and components, and it is necessary to reduce the temperature. It is necessary to strengthen ventilation for heat dissipation, which will cause safety protection and dustproof problems. In most parts of my country, the summer is hot and the temperature is high. Due to the compact structure of the box-type station and the small volume of the transformer, the temperature of the transformer is very high. In addition, the transformer generates a lot of heat during operation. At this time, natural ventilation is used to dissipate heat. It is difficult to meet the requirements, and sometimes the temperature of the box even exceeds 50 °C, which seriously increases the loss and failure rate of operating equipment. If the door is opened to dissipate heat, dust and dirt will easily enter, and special personnel should be sent to guard it to ensure safety.

In view of this, the existing problems are studied and improved, and a box-type transformer with a ventilation system is provided, which aims to solve the problem and improve the practical value through this technology.
