Outdoor box-type transformer substation

Abstract

The invention discloses an outdoor box-type transformer substation. The transformer substation comprises a transformer substation box base, a transformer substation box body is fixedly connected to the upper surface of the transformer substation box base, and hinges are fixedly connected to the front face of the transformer substation box body. A box door is fixedly connected to the transformer substation box body through the hinges, and a box door lock and a box door switch handle are arranged on the front face of the box door. The outdoor box-type transformer substation is convenient to detect whether dense smoke exists in the power transformation box and automatically give an alarm with the arrangement of a smoke detection alarm and is convenient to detect whether the temperature in thepower transformation box is high or not and automatically give alarm with the arrangement of a temperature sensing detection alarm; by arranging a compressed gas tank, a reservoir in the tank can compress the carbon dioxide conveniently; and by arranging a ventilation hose and a nozzle, the compressed carbon dioxide can be sprayed out of the nozzle conveniently, so that the effects that the firecan be detected automatically, and an automatic fire extinguishing function is started automatically when the fire is caused by the over-high temperature or short circuit in the transformer box, can be realized.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an outdoor box-type substation. Background technique [0002] With the development of society, people have higher and higher requirements for life safety, so they also need power distribution equipment with better use effect. Box-type substation is a widely used power distribution equipment, box-type substation, also called pre- Installed substation or prefabricated substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. The type of box-type substation can be divided into two types: ordinary and compact. The ordinary box-type substation has ZBW type and XWB type, etc., compact box-type substations include ZB1-336 and GE box-type substations. [0003] However, there are certain problems in the existing box-type substations. Because the box-type substations are mostly placed outdoors, it is very inconvenient...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain problems in the existing box-type substations. Because the box-type substations are mostly placed outdoors, it is very inconvenient to carry the box-type substations because of the huge size of the box-type substations. Although some box-type substations are convenient for transportation A trailer structure is added at the bottom, but this kind of box-type substation still has certain disadvantages in use. At the same time, the current box-type substation will place a fire extinguisher inside for safety.

[0004] At present, the outdoor box-type substation is fully sealed and unattended, and a sudden fire is not conducive to ventilation and fire fighting. It is easy to cause damage to the electrical components in the substation and make it unusable, which increases the maintenance cost of the box-type substation and affects Normal power supply in the area, and even an explosion, posing safety hazards
