Box-type substation

Abstract

The invention discloses a box-type substation which comprises a box and an automatic cooling system. The interior of the box is divided into three small chambers including a high-pressure chamber, a low-pressure chamber and a voltage transformation chamber by partitions, wallboards of each small chamber include inner wallboards and outer wallboards in spaced arrangement, the automatic cooling system is mounted in the box, and the outer wallboards are made of composite heat-insulating materials. The box is made of the composite heat-insulating materials, so that outside heat can be insulated from being transmitted into the box, and influences on operating of voltage transformation equipment in the box can be avoided. The automatic cooling system is mounted in the box, so that heat generated during operating of the voltage transformation equipment in the box can be discharged outside the box to guarantee the whole box-type substation to operate at a normal temperature, and safety of the substation is guaranteed.

Description

technical field [0001] The invention relates to a box-type substation, which belongs to the technical field of transformer equipment. Background technique [0002] In the power system, box-type substations are widely used. Box-type substations are a kind of factory prefabricated indoor / outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain wiring scheme. Realize functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution. The box-type substation includes a box body composed of a bottom plate, a wall plate and a top cover. The box body is divided into a high-voltage room, a transformer room and a low-voltage room by a partition. The high-voltage room, the voltage room and the low-voltage room correspond to the high-voltage switchgear, Distribution transformer and low-voltage power distribution device, the who...

AI Technical Summary

Problems solved by technology

However, unlike high-voltage switchgear and low-voltage power distribution equipment, distribution transformers will generate a lot of heat during operation, and if the heat is not dissipated in time, the temperature in the transformer room will be too high, and in severe cases, it will affect the normal operation of the transformer. work, and the fully enclosed structure of the existing box-type substation, the ventilation holes of the bottom plate cannot meet the heat dissipation, and the wall board of the box body uses a heat insulation board, although it can play a good role in heat insulation, especially in hot In summer, but in winter, there is a disadvantage that the heat is not easy to dissipate
