A box type substation

Abstract

The invention discloses a box-type transformer substation. The box-type transformer substation comprises a substrate and a box body, wherein the box body is arranged above the substrate; a top cover is connected above the box body; the top cover comprises a lower top cover fixedly connected above the box body, and an upper top cover installed on the lower top cover; the lower top cover comprises a longitudinal wall, and a slope wall fixedly connected with an upper end of the longitudinal wall; an external end of the slope wall is formed into an extension wall positioned outside the longitudinal wall; the upper top cover comprises a ventilating wall having a rectangular frame form, and an upper sealing plate fixedly connected with the upper end of the ventilating wall; the external end of the upper sealing plate is formed into the extension wall outside the ventilating wall; air vents are uniformly formed in the ventilating wall; axial flow fans are installed at positions, corresponding to a transformer chamber and a low voltage chamber, above the box body; top cover pushing rods which are longitudinally arranged are further installed at the positions, corresponding to two end portions of the upper sealing plate, above the top cover; and output rods of the top cover pushing rods are fixedly connected with the upper sealing plate of the upper top cover. The box-type transformer substation disclosed by the invention is compact in structure, reasonable in design, convenient in construction and good in heat dissipation effect.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a structure of a box-type substation. Background technique [0002] The Chinese patent with the document number CN204271514U discloses a waterproof box-type substation, which solves the problem that when natural disasters such as floods and heavy rains occur, a large amount of water will enter the box-type substation with a relatively high water level, which will cause damage to large-scale box-type substations. damage, the main point of the technical solution is to set up a lifting mechanism so that the power distribution equipment can be lifted up and down, and at the same time, the box is equipped with a stretching mechanism, and the height of the box can also be raised when the power distribution equipment is lifted, so that the water will not touch it. Power distribution equipment, to protect the power distribution equipment, the box can be stretched to ensure t...

AI Technical Summary

Problems solved by technology

However, such a heat dissipation method needs to continuously add water to the roof box, and the sealing performance requirements of the box and the water supply pipeline are high, and the load on the side wall of the box is increased, the structure is relatively complicated, and the practicability is not good.

In addition, the use of tap water for cooling will increase the air humidity around the substation, and there is a risk of electric leakage
