Abstract

The utility model belongs to the electrical category, and relates to a preassembled color-steel shell for a transformer substation, which is suitable for power supply, power transformation or power distribution systems. All middle upright posts, corner upright posts, upper crossbeams and lower crossbeams are formed by means of bending forming cold-rolled steel plates, an integral frame structure is assembled in an assembly manner, connection is realized by bolts completely, stripy lateral sealing plates are riveted with a frame by steel rivets to form box walls, sections of the box walls are bumpy, steel plates are welded to form a single-layer or double-layer upper cover, corrugated plates are laid on the top of the upper cover and are surface floor plates which are formed by means of one-step compression, the surface of the top of each corrugated plate is corrugated, the upper cover is integrally connected with the upper crossbeams by corner connecting plates and the bolts, and section steel is welded to form a base. The preassembled color-steel shell for the transformer substation has the advantages of waterproof property, insulation, corrosion resistance, ageing resistance, light weight, corrosion prevention, flame retarding, simplicity and convenience in processing, convenience in batch production and the like.

Description

Technical field

The electric information that the utility model relates to, be particularly related to the color steel of a kind of prepackage type transformer station shell, refer to especially a kind of have little, the color steel box-type substation of prepackage type box-type substation floor space handsome in appearance with matching in color consistent, the prepackage type coloured silk steel transformer station shell that is applicable to the big characteristics of north four seasons difference variation of surrounding environment.

Background technology

In the structural shape of existing substation equipment product,, and enjoy people's favor though preassembled transformer station has compact conformation, floor space is little, construction cost is relatively low characteristics.But owing to be subjected to the restriction of variations in temperature, such electric equipment serviceability and life-span all are affected; Though color steel box-type substation outward appearance is attractive in appearance, its main frame adopts full welding manner mostly, thereby has also that fabrication cycle is long, manufacturing process is cumbersome, the unmanageable problem of welding deformation.

The utility model content

The purpose of this utility model is to provide the color steel of a kind of prepackage type transformer station shell, solves the restriction that existing preassembled transformer station is subjected to variations in temperature, and electric equipment serviceability and life-span all are affected; Though color steel box-type substation outward appearance is attractive in appearance, its main frame adopts full welding manner mostly, thereby has also that fabrication cycle is long, manufacturing process is cumbersome, welding deformation problem rambunctious.

Each central post of the present utility model and corner post and entablature, sill are by the cold-rolled steel sheet bending and molding, adopt assembly type to be assembled into the general frame structure, and all adopt bolt to connect, particularly adopt half-round head square neck bolt to connect, and handle through hot galvanizing on the bolt surface, antiseptic property is good, and when assembling in box house with nut screwing clamping, play antitheft effect;

Tank wall adopts between bar shaped side seal board and framework and rivets with steel rivet, and its cross section is concavo-convex, wherein:

Individual layer or double-deck loam cake adopt steel plate to be welded, and color steel watt plate is laid at the top, and it is the surperficial bed board that die mould forms, and top surface is a corrugated, adopts gusset joint plate and bolt that loam cake and entablature are linked into an integrated entity;

The base base that is used to carry and support top cabinet and internal unit is welded by shaped steel;

Sill adopts bolt to be connected on the base;

Be convenient to pass in and out the plural part door leaf of installing with internal unit and adopt aluminium section bar and external application color steel to be made, doorframe is inlaid with the sealing bar;

The top of all corner posts and the outside of central post and entablature, sill is equipped with fire-retardant heat-preservation cotton, wherein:

Handle through hot galvanizing on hex bolts and half-round head square neck bolt surface.

Base is provided with the ventilation hole that is beneficial to circulation of air.

Advantage of the present utility model is:

1, frame structure adopts modular structural shape, is convenient to be assembled into different unit patterns, is applicable to the shell of the substation equipment of different size, model, and easy to assembly flexible, is convenient to transportation and installation.

2, all central post, corner post and entablature and sills all adopt the steel plate bending and molding, and this kind structure and production technology are compared with the section bar that is provided by section bar manufacturer is provided for use, have to save material the characteristics that reduce cost.

3, on the central post of main structural frame, corner post and the lower and upper cross-member and loam cake be provided with heat-insulation layer, help the insulation and heat insulation, improved the equipment operation condition of transformer station, be of value to the useful life that prolongs converting equipment.

4, have waterproof, insulation, corrosion-resistant, to be difficult for characteristic such as aging, in light weight, anticorrosion and fire-retardant good, and process easy, be convenient to characteristics such as batch process.
