Description

Box-type substation

Technical field

The present invention relates to a kind of transformer station, particularly to a kind of box-type substation, belong to technical field of electric equipment.

Background technology

Box-type substation is that the functions such as high powered, transformer pressure-reducing, low-voltage distribution are organically combined by one, and is arranged on the transformer station in a steel-structure box body totally-enclosed, moveable.Box-type substation has that complete property is strong, the power transmission cycle is short, environmental suitability is strong, easy for installation, the safe and reliable to operation and series of advantages such as small investment and instant effect, and therefore box-type substation is now widely used the public distribution in urban network construction and upgradation.Along with the modernization of urban construction is accelerated, box-type substation will progressively substitute original civil engineering power distribution room, become novel complete power distribution equipment.

Tradition box-type substation divides by structure mainly American box substation and European box-type substation, and the various equipment height in box-type substation differ, and adopts Chinese character pin-shaped or order font plane formula alignment placement more.From technical standpoint, the major defect of box-type substation is poor radiation: owing to this class formation is to be combined in the big casing of an opposing seal by multiple electrical equipment, but for reaching the requirements such as protection against the tide, waterproof, damp proof and sealing, so the heat dispersion limited in casing, and the temperature rising problem caused due to poor radiation can cause the temperature rise of electrical equipment in casing to exceed standard, thus affecting service life and the safety of equipment.In prior art, conventional increase electric fan or other device forced-ventilateds are lowered the temperature to ensure that temperature does not exceed standard, but cooling radiating effect is not as.Additionally, because of box-type substation self-radiating poor-performing, therefore the floor space increasing box-type substation of having to is to maintain the heat-dissipating space of each parts in its casing.From the foregoing, it will be observed that the requirement of heat dispersion has been become conflict body with its box volume and floor space in box-type substation, all restricted on causing on its capacity and using.

So, the later stage is in that for the research emphasis of box-type substation, maintains needed for it under premise of heat dispersion, and reduces its volume and/or floor space further.In prior art, it is attained in that 1, half buried (also known as buried) box-type substation mainly through two ways, 2, compact box-type substation.All there is different shortcomings in both box-type substations, particularly as follows:

1, half buried box type transformer substation, this type of box-type substation imbeds underground mainly by by the half or more box portion of box-type substation, or whole transformer portion is imbedded underground, thus reducing the ground volume of box-type substation, its floor space can not be reduced；And before installing and using, it is required for arranging the size box type transformation station base in (2.4*3.4) left and right on ground and the degree of depth be the mounting foundation about (1.5-1.8m).This type of box type transformation stands in the ground construction not only needing high cost when coming into operation, and box-type substation is to be placed directly in earth foundation surface in use.Due to ground easy hydrops, dampness is big, and ventilation effect is bad, and components and parts are easily damaged, and adds the weight of box-type substation itself, extremely difficult discovery during the abnormal conditions such as geological transformation or equipment hydrops occurs, it is easy to security incident occurs.Particularly when coming into operation in old town, owing to the pipelines such as underground water power and communication gather, inconvenience of not only constructing, road also will be brought great inconvenience.Chinese patent application CN2012206032235.2 and 201210152564.8 all disclose the structure of a kind of half buried box type transformer substation.Half buried casing transformer station by transformator as underground, therefore the volume that box type transformation stands on the ground is substantially reduced, but owing to transformator is as under bottom surface, the predictability of security incident is not strong, moist underground environment is big to equipment damage, dampness in ground pedestal is also very big on equipment impact, is easier to cause security incident at hydrops in rainy season.

2, compact box-type substation, this type of box-type substation mainly reduces its volume and floor space simultaneously, and the minimizing of floor space is reduced by its volume and realizes, but equally still cannot avoid the requirement of mounting foundation.Such as these four patents of Chinese patent application CN201220341565.2, CN201220049333.X, CN201010165374.0 and patent CN03267020.6, all disclose the power transformation box of a kind of compact.They common features for all carrying out different alignment placement in same level to box-type substation internal structure, to reduce the plane floor space of box-type substation.But this kind of arrangement only reduces the floor space of box-type substation on local direction, do not change that the plane of tradition box-type substation is Chinese character pin-shaped or order font structure, the spatial volume of box-type substation can not be made significantly to reduce.

Therefore, in prior art, box-type substation is bulky, not only affects city or street attractive in appearance, also limit box type transformation and stands in narrow avenue or the use of other narrow spaces.And above-mentioned each box-type substation all requires just to assemble before dispatching from the factory complete, complete machine transports, and often the transport vehicle of ten tons is only capable of one box-type substation of transport or a transport vehicle ten meters long also can only transport two box-type substations, extremely wastes resource；Owing to use environment or the technical parameter of box-type substation require that it takes individuation customized type, cannot produce in batches as standard component, cause market is full of the various kinds of equipment and the accessory that are largely used to box-type substation, diversified in specifications, standard differs, also result in the waste in production equally, be unfavorable for energy-conserving and environment-protective.Additionally, above-mentioned various box-type substation there is also the problem of maintenance inconvenience, the casing major part of box-type substation adopts enclosed housing, entrance during by opening the door or window as maintenance；When needs overhaul, often people pierces in casing and overhauls, no matter safety or ease for operation all exists bigger problem；During in particular for half buried box type transformer substation maintenance, even needing again to destroy after road surface is excavated can enter in casing, when being placed in underground such as above-mentioned transformator, safe predictability is relatively low, brings great inconvenience to maintenance and maintenance.Additionally, existing various box-type substation adopts " product " or " order, day " word formula subregion mostly, main equipment adopts back-to-back type to place, and adopts dividing plate to separate, and therefore can form certain dead corner, have a strong impact on heat radiation.

Chinese patent CN201220265651.X discloses a kind of LED street lamp Special box-type substation, this LED street lamp box-type substation is only for the power supply of LED street lamp, because of it, to cross electricity little, so each parts are few in this box-type substation, therefore its internal wiring is made to become a U-shaped by simply stacking for parts each in box-type substation, thus make use of vertical space to a certain extent, reduce the volume of the box-type substation of this LED.But this LED box-type substation equally exists gravity-flow ventilation dead angle；And owing to the capacity of the equipment such as transformator of this box-type substation is less, so the body structure planting LED street lamp Special box-type substation cannot be applicable to the medium-and-large-sized box-type substation (200KVA-630KVA) of town and country distribution；In addition, in this box-type substation, by the same side inlet wire outlet of its casing, and outlet position is higher, so the function division of this box-type substation structure is unclear, each function device spacing is too near, is packed together, and brings a degree of inconvenience to maintenance and maintenance.

Additionally, box-type substation main heat sink source is the transformator in casing；And oil-filled transformer (oil formula transformator) is because of its good heat dissipation, the advantage such as loss is low, capacity is big, becoming in current national grid, especially the transformator in box-type substation is first-selected；Wherein ensure that the excellent heat dispersion performance of transformator is one of key technology performance of transformator.The type of cooling of oil-filled transformer mainly has four kinds both at home and abroad at present, i.e. Natural Oil Circulation Power self-cold radiating, Natural Oil Circulation Power wind-cooling heat dissipating, forced oil-circulation wind-cooling heat dissipating and forced oil circulation water-cooling heat radiation.Natural Oil Circulation Power wind-cooling heat dissipating mode is after utilizing Transformer Winding and heating unshakable in one's determination, intrinsic oil forms convection current, after oil flows through radiator, the wind of cooling fan blowout is taken away by heat, thus reaching the purpose of heat radiation, this type of cooling is mainly used in Transformer.The effect by oil pump of the forced oil-circulation wind-cooling heat dissipating mode, makes the oil in transformator be forced Rapid Circulation, when oil flows through radiator, the wind of cooling fan blowout is taken away by heat, and this type of cooling is mainly used in big-and-middle-sized transformator.The main distinction of forced oil-circulation forced air cooler and Natural Oil Circulation Power forced air cooler is to adopt oil-immersed pump forced oil to be circulated, and so oil Flow Velocity is accelerated, and cooling effectiveness is improved.The fundamental type of traditional oils immersion transformer radiator is mainly by following several:

1, gilled radiator

In oil-filled transformer, 80% is above adopting the type of cooling of Natural Oil Circulation Power.When oil-filled transformer capacity is more than 50kVA, so that it may consideration tubular type or gilled radiator are as the heat-exchange device of transformator.The transformator transverse direction volume of gilled radiator is excessively huge, and transport and maintenance are all very inconvenient.Chip radiating efficiency is very low, although be used widely in low capacity transformator dispels the heat, but is difficult to solve the heat dissipation problem of high-power transformer.

2, forced air cooler

When oil-immersed power transformer capacity is more than 50MVA, so that it may be considered as forced air cooler.Transformator top layer high temperature oil is sent in cooler cooling tube by forced air cooler by oil pump, the heat of its generation is passed to cooling tube inwall and fin, then is released heat by tube wall and fin to air.Adopt high-power forced air cooler not only to install to the manufacture of transformator, use, keep in repair and bring convenience, and leakage of oil can be reduced.Will depend upon which the cooling element of employing in forced air cooler cooling effect and service life, cooling element made by the domestic pipe that is generally adopted.In cold weather area and few water area, big, special type oil-filled transformer forced air cooler is best suitable for.For long-term temperature higher thermal band area, the problem that the specified cooling capacity of forced air cooler declines to some extent to be considered.

3, water cooler

When oil immersed power transformer capacity is more than 50MVA, except adopting forced air cooler to carry out except heat exchange, water cooler also can be adopted as the heat-exchange device of high-power transformer.The specific heat of air is only the 1/4 of water, so water cooler is than forced air cooler good cooling results；The ratio of heat transfer coefficient water cooler heat transfer coefficient of air side is low, so two kinds of coolers that cooling capacity is essentially identical, water cooler is less than the volume of forced air cooler, lightweight, noise is low.Current domestic water cooler separate unit heap(ed) capacity has reached more than 315kW, has abroad reached more than 500kW.Domestic water cooler adopts single tube structure, so occurring cooling copper tube in too much cause water cooler to break the situation in the oil making cooling water enter into transformator, owing to cannot find that water has enter in transformer oil in time, the transformer oil insulating properties into water are often made significantly to decline, thus causing operating transformator generation major accident.

Water cooler has cooling effectiveness height, low noise advantages, and dual pipe water cooler improves the reliability of water cooler, is highly suitable for there is water source area.The dual pipe water cooler technical performance of domestic production and structure are suitable with international standard.The frost problem of cooling water is considered for cold district.

4, radiating cooler

Being generally adopted forced air cooler or the water cooler heat-exchange device as oil-filled transformer large-scale, super-huge, both cooler cooling effectiveness are high.But owing to oil pump and blower fan run without interruption, therefore there is the shortcomings such as noise is big, the subsidiary engine proportion of goods damageds are high, maintenance workload is big.For solving above-mentioned contradiction, Europe occurs in that one is referred to as the novel cooling manner of " radiating cooler ".Radiating cooler refers to that its radiating surface is based on gilled radiator, coordinates blower fan and oil pump to cool down simultaneously, and when transformer load rate is about 50%, gilled radiator is in oil state self-cooled and runs；When transformer load rate reaches about 75%, starting blower fan, gilled radiator is in the air-cooled operation of oil state；When transformator at full capacity time, start oil pump put into operation, put into oil pump strong oil wind cold type run.

It is not difficult to find out, in order to maintain preferably heat dispersion, above-mentioned transformator is all adopt foreign compulsion heat radiation, and adopt natural heat dissipation often because the topology layout of its box-type substation self is limit, the natural heat dissipation system that convection current is good cannot be formed, and from having to by the above-mentioned heat dissipation equipment that forces, equipment in box-type substation is increased, thus causing that cost of manufacture and maintenance difficulties all have increase, in addition above-mentioned all kinds of supplemental heat rejected facility is low for environment versatility, often because box-type substation local environment is limit, the thermolysis of its best cannot be played, cannot be suitable for what is more or completely.

To sum up stating, there are the problems such as volume big, maintenance inconvenience, natural heat dissipation poor performance, environmental suitability difference in box-type substation in the market, this also makes the popularization that box type transformation stands in China be somewhat limited.
