Description
Technical field
This utility model belongs to transformer station's technical field, and being specifically related to one has load high pressure compensation preassembled transformer station.
Background technology
Along with the fast development of national economy and society, electric power energy demand is also increasing, and soil and space resources are more and more rare, and in Electric Power Network Planning, the site of transformer station and line channel implements also difficulty further.The features such as power grid construction presents task weight, it is high to require, the duration tight, expropriation of land and policy difficult treatment, the construction difficulty increasing of transformer station.Owing to urbanization, industrialization quickly propel the needs with rapid economic development, Electric Power Network Planning to adapt with urban economy, development plan, power grid construction progress should adapt with national economy and social development, and the construction of transformer station is the important component part of power grid construction.
The construction mode of tradition transformer station mainly has following several:
Large-scale Out-door Substation construction mode: high-tension switch gear adopts outdoor arrangement form, transformator is placed on open air, 20 (10) kV equipment adopt indoor switch cabinet form to be arranged in switch gear room, each electrical equipment adopts outdoor connected mode, namely adopt nuditing wire or bus terminal block between equipment, utilize outdoor structures support to support and be attached.Owing to high pressure equipment and connection thereof are directly exposed to open air, the requirement of environment and Insulation Coordination is higher, the usual framework of transformer station is towering, high-voltage line layout is complicated, and the volume of electric power facility and spacing are relatively big, and land occupation is more, inharmonious with surrounding enviroment, building site selects relatively difficult.
Indoor type transformer substation construction pattern: electrical equipment is all or part of be arranged on indoor.Its high pressure equipment many selections gas-insulated provision for sealing, between each electrical equipment, many employing cable mode connect.Indoor type transformer station to some extent solves the contradiction between transformer station and soil, environment, however it is necessary that existing apartment construction, and installation, debugging work load are greatly, and long construction period, overall cost exceeds about 1 times than outdoor substation.
Underground or semi-subterranean substation construction mode: this pattern is close to indoor type transformer substation construction pattern, simply it is arranged on below ground by all or part of for all electrical equipments, the more efficiently land area that saves, but the transformer substation construction of this pattern and maintenance operation expense are high.
Three of the above transformer station pattern is all after equipment dispersion transports scene to, then carries out the construction mode of installation and debugging.They existence have the drawback that, can grind project verification from transformer station and put into operation to completion, and each transformer station is required for through complex processes such as design, bid, in-site installation, field adjustables.
European-type box becomes also known as complete set transformer station, is also called prefabricated substation, because of its have combination flexibly, be readily transported, migrate, easy for installation, short construction period, operating cost are low, floor space is little, the advantage such as pollution-free, non-maintaining, in widespread attention.In the extension of rural power grids (transformation), it is widely used in the construction and upgrading of city, the electric institute of the middle-size and small-size change of rural area 10～110kV (joining), factories and miness and mobile operational process electric substation, because it is prone to go deep into load center, reduce radius of electricity supply, improve terminal voltage quality, it is particularly well-suited to upgrade of rural power grids, is described as the target pattern of 21 century electric substation's construction.
Application number a kind of transformer station box structure that has been the patent disclosure of 201420513302.4, including base, the side plate being made up of composite, chamber door and top cover, it is divided into transformer room, altitude chamber and low-pressure chamber by dividing plate at described box house, described transformer room, altitude chamber are connected with low-pressure chamber top, it is provided with air grid in the left and right sides of the eaves ridge place casing of top cover, described air grid is internally provided with fly net, be provided with blower fan on top cover top, described air grid is the flap that mutual boil on the nape opposite the mouth intersects the V-shaped of setting or groove.This utility model adopts composite can increase its corrosion resistance and service life, can adapt in different regions, the vile weather of Various Seasonal, simultaneously its can effectively prevent weather to be quenched, the dew condensation phenomenon of shock heating appearance, it is to avoid the excessive short circuit accident caused of box house humidity.Current domestic electrical user and transformer station's major part also all adopt fixed capacity device to carry out reactive-load compensation, and it can not realize idle dynamic balance, often occur mending and owe to mend phenomenon, and cause line loss too high.On market, existing (European) preassembled transformer station all adopts No-load changer oil-filled transformer or Cast Resin Dry-Type Transformer, and transformator itself does not have reactive power compensation planning.Traditional European-type transformer substation is primarily present following problem: 1, power factor is on the low side, does not reach Standard.Cause electric power environmental dirty so.2, line loss is bigger.Current China electric power system loss rate more than 6%, and Japan, European and American developed countries' electric wire loss rate only have about 3%.3, transformer load loss is excessive, and meritorious output is on the low side.
