Description

Composite type cabinet type transformer substation
Technical field
The utility model relates to a kind of box type transformation station equipment, is specifically related to a kind of composite type cabinet type transformer substation.
Background technology
Box-type substation, claim again preassembled transformer station, also referred to as prefabricated substation, by certain mode of connection assembling all-in-one-piece preassembled transformer station, comprise primary equipment, secondary device, ac and dc systems, measuring equipment, communication apparatus etc., because it has that environmental suitability is strong, compact conformation, combination flexibly, be convenient to transportation, migration, easy for installation, short construction period, operating cost is low, floor space is little, the advantage such as pollution-free, safe and reliable to operation, non-maintaining, therefore, in widespread attention and application.Particularly application is very extensive abroad, accounts for more than 70% of transformer station's sum in West Europe, and the U.S. is 90%.Being applied as 10% in China, is a kind of equipment in the ascendant.Preassembled transformer station is the power transmission and transforming equipment developing direction, and by front described, China application is 10% left and right only, and abroad reached 70~90%, so its social benefit of preassembled transformer station is remarkable, the scope of application is wider.
Its general structure mainly contains two kinds of forms: a kind of is composite type, and another kind is integral type.Composite type arranges it is that high voltage switchgear, transformer and low-voltage distribution equipment three parts are respectively that a ,Ji You hyperbaric chamber, Room, transformer room and three compartments of low-pressure chamber form, and can arrange by " order font " or " Chinese character pin-shaped "." order font " arranged with " Chinese character pin-shaped " and arranged and compare " order font " wiring more for convenience, therefore mostly adopt " order font " to arrange.But " Chinese character pin-shaped " arrangement is comparatively compact, particularly, when transformer room arranges many transformers, " Chinese character pin-shaped " arranges comparatively favourable.
Nonmetal outward appearance pre-mounted box type transformer substation, be fixedly to form with bolt and pulling rivet, and it is the assembling of casing primary structure skeleton itself that bolt is used part; Chamber door is first with rivet, to become an integral body with backplate, and then the integral body after riveted joint is installed and its correspondence position with pulling rivet.Because backplate and chamber door are the chief components of four metopes of box-type substation, it is again rivet, whole box change in lifting and transportation, some slight deformation unavoidably, the material of the pull rivet head of rivet is again aluminum, and the mechanical strength of its carrying is not as the intensity of screw thread.Case becomes in the lifting process, has the slight deformation become because of case to cause the risk that pull rivet head comes off, and therefore, at whole case, becomes in transportation, and road quality classification is had to higher requirement.
Above-mentioned existing nonmetal outward appearance pre-mounted box type transformer substation, its shortcoming is, 1) a little less than its fire-resistant fire protecting performance, all limitation of erecting bed; 2) lifting and transportation are all had higher requirements.
In addition, box-type substation also is faced with following basic technique problems.
1) condensation problem, it is large that case becomes the outdoor use temperature difference, draws badly and may make high and low pressure switchgear surface condensation occur and cause the flicker electric discharge phenomena, causes insulation to descend; 2) transformer heating problem, will take into full account the problem of how to be dispelled the heat during design; 3) casing etching problem, case becomes for outdoor, and casing unavoidably can be in situations such as acid rain, the sun are exposed to the sun, so casing should have the characteristics such as rotproofness, ultra-violet radiation resisting in atmosphere; 4) dirt problems, guarantee the normal operation of electric equipment by natural draft, but that dust is brought in the natural draft meeting into is unfavorable to insulating, so casing should have dust prevention.
The utility model content
The utility model provides a kind of composite type cabinet type transformer substation, so that the problem that deformation, result of ventilating heat dissipation are poor, easily accumulate dust easily to occur a little less than solving the fire resistance existed in prior art, in the lifting process.
For achieving the above object, by the following technical solutions:
A kind of composite type cabinet type transformer substation, comprise by column, upper and lower crossbeam, backplate, chamber door, base, case top, described column and backplate removably connect to form casing by bolt, described base removably is connected by bolt with sill, between described upper and lower crossbeam and column, by bolt, removably be connected, described case top removably is connected by bolt with entablature; Described case top is the herringbone ridge structure, and the left and right sides on described case top removably is connected with the side plate with louvre by bolt, and the inside on described case top is provided with thermal insulation board; The surrounding on described case top is provided with heat dissipation channel along bottom, in described casing, exhaust blower is installed; Described chamber door bottom arranges the passive air-leg that promising chamber door opens and closes; Be provided with aeration structure on described chamber door.
Preferably, the aeration structure of described chamber door is that many of arranging in chamber door are that fasten and with the ventilating board of gapped " several " character form structure mutually, and described ventilating board is by being fixed on the door-plate of chamber door with the perpendicular reinforcement of ventilating board.
Preferably, also be provided with central post on described base, described central post removably is connected by bolt with upper and lower crossbeam.
Preferably, described column and upper and lower crossbeam are that the 2.5mm thick cold rolled steel sheet bends moulding.
Preferably, described chamber door and backplate are the moulding of 2mm thick cold rolled steel sheet double-fold.
Preferably, in described casing, be provided with dividing plate, by described dividing plate, the space interval in casing become to hyperbaric chamber, low-pressure chamber and transformation chamber.
Preferably, the front-to-back slope steel plate on described case top is that the 2mm thick cold rolled steel sheet bends and forms.
Preferably, edge, described case top is provided with drip.
Preferably, described base is fixedly connected with and is formed by channel-section steel.
Preferably, the material that described chamber door, case top, backplate adopt is the aluminizing zine plate.
The beneficial effects of the utility model: because described base removably is connected by bolt with sill, between described upper and lower crossbeam and column, by bolt, removably be connected, described case top removably is connected by bolt with entablature, so the utility model makes the utility model realize the modular function of structure by removably connecting between each member, assembling process is simply laborsaving; Because the case top is the herringbone ridge structure, the left and right sides on described case top removably is connected with the side plate with louvre by bolt, the inside on case top is provided with thermal insulation board, the surrounding on case top is provided with heat dissipation channel along bottom, exhaust blower is installed in casing, makes the utlity model has good radiating effect; Due to the aeration structure of chamber door be in chamber door, arrange have many that mutually fasten and form with the ventilating board of gapped " several " character form structure, so ventilating board can not only play the effect of heat radiation, can also play the effect that intercepts dust; Because edge, case top is provided with drip, effectively avoided the facility in casing to be caught in the rain; The material adopted due to described chamber door, case top, backplate is the aluminizing zine plate, so the utlity model has erosion-resisting performance preferably.
