Embodiment 1

[0049] A combined substation, including a chassis 1, a box body 2, and a top cover 3. The box body 2 includes an upper support 21, a lower base 22, a column 23, and a corner column 24. The upper part of the box body 2 is provided with a top cover 3, and the box body The bottom part of 2 is provided with chassis 1; The inner wall of described chassis, casing, top cover is all sprayed with zinc-rich paint, and the surface of described zinc-rich paint is sprayed with anti-corrosion material layer, and described anti-corrosion material comprises the raw material of following parts by weight Prepared: water-based resin 55, zinc tripolyphosphate 10, toluenesulfonic acid 6, hydroxyethylidene diphosphonic acid 6, XR-424 additive 7, fumaric acid 2, dimethyl sulfoxide 1, deionized water 15. Wherein, the water-based resin is a mixture of water-based epoxy acrylic resin and water-based double-crosslinked acrylic emulsion, and the weight ratio of the two is 3:1; after the anti-corrosion ma...

Embodiment 2

[0054] The combined substation of this embodiment has the same structure as that of Embodiment 1, the difference is that:

[0055] The anti-corrosion material is prepared from the following raw materials in parts by weight: water-based resin 75, zinc tripolyphosphate 20, toluenesulfonic acid 10, hydroxyethylidene diphosphonic acid 9, XR-424 additive 10, fumaric acid 5, Dimethyl sulfoxide 3, deionized water 25. Wherein, the water-based resin is a mixture of water-based epoxy acrylic resin and water-based double-crosslinked acrylic emulsion, and the weight ratio of the two is 5:1; after the anti-corrosion material layer is sprayed, the whole equipment is placed in 55°C hot air 4 hours under conditions. The preparation method of the anti-corrosion material includes the following steps: S1. After preparing the materials, sequentially add deionized water, zinc tripolyphosphate, toluenesulfonic acid, hydroxyethylidene diphosphonic acid, and XR-424 auxiliary agent into the reaction ...

Embodiment 3

[0057] The combined substation of this embodiment has the same structure as that of Embodiment 1, the difference is that:

[0058] The anti-corrosion material is prepared from the following raw materials in parts by weight: water-based resin 65, zinc tripolyphosphate 15, toluenesulfonic acid 8, hydroxyethylidene diphosphonic acid 7, XR-424 additive 9, fumaric acid 3, Dimethyl sulfoxide 2, deionized water 20. Wherein, the water-based resin is a mixture of water-based epoxy acrylic resin and water-based double-crosslinked acrylic emulsion, and the weight ratio of the two is 4:1; after the anti-corrosion material layer is sprayed, the whole equipment is placed in a hot air at 50°C 3.5 hours under conditions. The preparation method of the anti-corrosion material includes the following steps: S1.

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...
