Multifunctional comprehensive box-type substation with high integration density

Abstract

The invention provides a multifunctional comprehensive box-type substation with high integration density. The multifunctional comprehensive box-type substation comprises a box body, wherein the box body comprises a bottom plate, a wall body and a head cover; a high-voltage chamber, a transformer chamber, a low-voltage chamber and an industrial personal computer are arranged in the box body; the transformer chamber is provided with a high-voltage adjacent surface adjacent to the high-voltage chamber, a low-voltage adjacent surface adjacent to the low-voltage chamber, an outer wall adjacent to the outside and an open mesh door for passing in and out of the transformer chamber; an inner-layer steel plate and an outer-layer steel plate are arranged in the wall body surrounding the transformer chamber and a partition plate respectively; a hollow cavity is arranged between the inner-layer steel plate and the outer-layer steel plate; fireproof and soundproof cotton is arranged in the hollow cavity; the surface of the outer-layer steel plate is coated with a radiating, heat-dissipating and cooling paint; the inner-layer steel plate is arranged close to the inside of the transformer chamber; and the outer-layer steel plate is arranged outside the transformer chamber. In the box-type substation, the high-voltage chamber, the low-voltage chamber and the transformer chamber all are provided with doors and windows; and an exhaust fan is arranged on each window, so that combination of natural ventilation and mechanical ventilation is achieved; and maintenance and repair are also facilitated.

Description

technical field [0001] The invention relates to the field of substations, in particular to a highly integrated multifunctional comprehensive box-type substation. Background technique [0002] With the rapid development of economic construction and the acceleration of urbanization in my country, various commercial buildings, public supporting buildings, residential complexes and large industrial parks are emerging all over the country; box-type substations, as supporting power facilities, have been installed in various places. widely used. [0003] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It is about high-voltage power receiving, transformer step-down, low-voltage distribution Functions such as electricity are organically combined and installed in a steel struct...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, multiple devices in the box-type substation are concentrated and distributed, and the space is small. Especially in summer, the temperature inside the substation is very high under the sunlight. The commonly used cooling devices for box-type substations are mostly cooling fans. Running, the hot air inside the substation is pumped out, which consumes a lot of energy

In addition, because the box-type substation needs to be kept within a certain humidity range and the box is usually sealed, it is difficult to guarantee the heat dissipation effect and humidity at the same time, and the safety performance is low, so the service life is not long

[0005] In the existing technology, the low-voltage power distribution room of the box-type substation has a single function, and the output voltage of the low-voltage part is difficult to provide multiple voltage modes

Moreover, in the operation of the box-type substation, users lack the understanding of the operation information of the entire box-type substation, and can only obtain the operation information of the box-type substation from a single perspective, lacking the overall control of the operation of the box-type substation, so the box-type substation There are serious risks in the operation of
