Combination type substation

Abstract

The invention discloses a combination type substation. The combination type substation comprises a chassis, a box and a top cover, wherein the box comprises an upper bracket, a lower bracket, stand columns and corner columns; the top cover is arranged at the upper part of the box; the chassis is arranged at the lower part of the box; zinc-rich paint is sprayed to the inner walls of the chassis, the box and the top cover; an anti-corrosion material layer is sprayed to the surface of the zinc-rich paint; the anti-corrosion material is prepared from raw materials in parts by weight as follows: 55-75 parts of waterborne resin, 10-20 parts of zinc tripolyphosphate, 6-10 parts of toluene sulphonic acid, 6-9 parts of etidronic acid, 7-10 parts of an XR-424 auxiliary, 2-5 parts of fumaric acid, 1-3 parts of dimethyl sulfoxide and 15-25 parts of deionized water; after spraying of the anti-corrosion material layer is finished, the whole equipment is left under the condition of hot air at 45-55 DEG C for 3-4 h. According to the combination type substation, processing precision and processing efficiency of parts are improved, and content of VOC (volatile organic compounds) in exhausted hot airis greatly reduced.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a combined substation. Background technique [0002] The combined substation has been widely valued because of its flexible combination, convenient transportation, relocation, convenient installation, short construction period, low operating cost, small footprint, no pollution, and maintenance-free; It is widely used in the construction and renovation of 10-110kV small and medium-sized substations (distribution) substations in urban areas and rural areas, factories and mines, and substations for mobile operations. Because it is easy to penetrate into the load center, reduce the radius of power supply, and improve the quality of terminal voltage, it is especially suitable Transformation of rural power grids. [0003] At present, the housings of combined substations on the market are mostly welded, which has low processing accuracy and efficiency, and takes up too much space d...

AI Technical Summary

Problems solved by technology

[0003] At present, the shells of combined substations on the market are mostly welded, with low processing accuracy and efficiency, and take up too much space during transportation. At the same time, it is time-consuming and laborious to replace parts, which increases labor costs and welding costs.

[0004] The applicant has developed a combined substation before, which can realize modular assembly through splicing and installation, improve processing accuracy and processing efficiency, and at the same time replace parts easily and conveniently, reduce welding cost and labor cost, and adopt traditional anti-corrosion paint Anti-corrosion, but in practice, it is found that the combined substation using traditional anti-corrosion paint will contain a large amount of VOC in the hot air discharged during use
