Description

Box-type substation

Technical field

The utility model relates to a kind of transformer station, and particularly a kind of box-type substation, belongs 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 totally-enclosed, a moveable steel construction casing.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 has now been widely used in 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 and mainly contains American box substation and European box-type substation, and the various equipment height in box-type substation differ, and adopts plane formula alignment placement that is Chinese character pin-shaped or order font more.From technical standpoint, the major defect of box-type substation is poor radiation: because this class formation is combined in the large casing of an opposing seal by multiple electric equipment, but for reaching the requirements such as protection against the tide, waterproof, damp proof and sealing, so limit the heat dispersion in casing, and the temperature rising problem caused due to poor radiation can cause the temperature rise of electric equipment in casing to exceed standard, thus affect useful life and the fail safe of equipment.In prior art, conventional increase electric fan or the cooling of other device forced-ventilateds are to ensure that temperature does not exceed standard, but cooling heat dissipation effect is not fine.In addition, because of box-type substation self-radiating poor-performing, therefore the floor space of increase box-type substation of having to is to maintain the heat-dissipating space of each parts in its casing.As from the foregoing, conflict body is become to the requirement of heat dispersion and its box volume and floor space in box-type substation, to have caused on its capacity and all restricted on using.

So the later stage is for the research emphasis of box-type substation, under maintaining the prerequisite of heat dispersion needed for it, and reduce its volume and/or floor space further.In prior art, realize above-mentioned purpose mainly through two kinds of modes: 1, half buried (also known as buried) box-type substation, 2, compact box-type substation.All there is different shortcomings in these two kinds of box-type substations, is specially:

1, half buried box type transformer substation, this type of box-type substation is mainly by imbedding underground by the half or more casing parts of box-type substation, or whole transformer portion is imbedded underground, thus reduce the ground volume of box-type substation, its floor space can not be reduced; And the mounting foundation about all to need to arrange on ground the box type transformation station base of a size in (2.4*3.4) left and right and the degree of depth before installing and using be (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 directly positioned over earth foundation surface in use.Due to ground easy ponding, moisture is large, and ventilation effect is bad, and components and parts easily damage, and adds the weight of box-type substation itself, and extremely difficult discovery when there are the abnormal conditions such as geology change or equipment ponding, easily security incident occurs.Particularly when coming into operation in old town, because the pipelines such as underground water power and communication gather, inconvenience of not only constructing, also will bring great inconvenience to road.Chinese patent application CN2012206032235.2 and 201210152564.8 all discloses a kind of structure of half buried box type transformer substation.Half buried casing transformer station by transformer as underground, therefore the volume that box type transformation stands on the ground reduces greatly, but because transformer is as under bottom surface, not strong to the foresight of security incident, moist underground environment is large to equipment damage, moisture in ground pedestal is also very big on equipment impact, easilier causes security incident at ponding 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.As these four patents of Chinese patent application CN201220341565.2, CN201220049333.X, CN201010165374.0 and patent CN03267020.6, all disclose a kind of power transformation box of compact.Their common features for all to carry out different alignment placement to box-type substation internal structure in same level, 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 the Chinese character pin-shaped or order font structure of the plane of traditional box-type substation, 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 the transport vehicle that often transport vehicle of ten tons only can transport a box-type substation or ten meters long also can only transport two box-type substations, very wastes resource; Because the environment for use of box-type substation or technical parameter require that it takes individuation customized type, cannot produce in batches as standard component, cause market is full of in a large number for various kinds of equipment and the accessory of box-type substation, diversified in specifications, standard differs, also result in the waste in production equally, be unfavorable for energy-conserving and environment-protective.In addition, also there is the problem of maintenance inconvenience in above-mentioned various box-type substation, and the casing major part of box-type substation adopts enclosed housing, by opening the door or window as entrance during maintenance; When needs overhaul, people pierces in casing and overhauls often, no matter fail safe or ease for operation all exists larger problem; Especially, time for half buried box type transformer substation maintenance, even need again to destroy after road surface is excavated can enter in casing, as safe foresight is lower when above-mentioned transformer is placed in underground, bring great inconvenience to inspection and maintenance.In addition, existing various box-type substation adopts " product " or " order, day " word formula subregion mostly, and main equipment adopts back-to-back type to place, and adopts baffle for separating, 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 with box-type substation 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 there is natural draft dead angle equally in this LED box-type substation; And due to the capacity of the equipment such as transformer of this box-type substation less, so the body structure of 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 inconvenience to a certain degree to inspection and maintenance.

In addition, box-type substation main heat sink source is the transformer in casing; And oil-filled transformer (oily formula transformer) is because of its good heat dissipation, the advantage such as loss is low, capacity is large, become in current national grid, the transformer especially in box-type substation is first-selected; Wherein ensure that the excellent heat dispersion performance of transformer is one of key technology performance of transformer.The type of cooling of oil-filled transformer mainly contains 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, and after oil flows through radiator, heat is taken away by the wind blown out by cooling fan, thus reaching the object of heat radiation, this type of cooling is mainly used in Transformer.Forced oil-circulation wind-cooling heat dissipating mode, by the effect of oil pump, makes the oil in transformer be forced to Rapid Circulation, and when oil flows through radiator, heat is taken away by the wind blown out by cooling fan, and this type of cooling is mainly used in big-and-middle-sized transformer.The main distinction of forced oil-circulation forced air cooler and Natural Oil Circulation Power forced air cooler adopts oil-immersed pump forced oil to circulate, and so oily Flow Velocity is accelerated, and cooling effectiveness is improved.The fundamental type of traditional oils immersion transformer radiator is primarily of following several:

1, gilled radiator

In oil-filled transformer, more than 80% is the type of cooling adopting Natural Oil Circulation Power.When oil-filled transformer capacity is greater than 50kVA, just can consider with tubular type or the gilled radiator heat-exchange device as transformer.The horizontal volume of transformer of gilled radiator is too huge, transports and keeps in repair all very inconvenient.Chip radiating efficiency is very low, although be used widely in the heat radiation of low capacity transformer, is difficult to the heat dissipation problem solving high-power transformer.

2, forced air cooler

When oil-immersed power transformer capacity is more than 50MVA, just can consider to adopt forced air cooler.Transformer top layer high temperature oil is sent in cooler cooling water pipe by oil pump by forced air cooler, and the heat produced passes to cooling water pipe inwall and fin, then releases heat by tube wall and fin to air.High-power forced air cooler is adopted not only to bring convenience to the making and installation of transformer, use, maintenance, and can leakage of oil be reduced.Forced air cooler cooling effect and useful life will depend on the cooling element of employing, and cooling element made by domestic general employing pipe.In cold weather area and few water area, large, special type oil-filled transformer forced air cooler is the most applicable.For long-term temperature higher thermal band area, the problem that the specified cooling capacity of forced air cooler declines to some extent be considered.

3, water cooler

When oil immersed power transformer capacity is more than 50MVA, except employing forced air cooler carries 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 1/4 of water, so water cooler is than forced air cooler good cooling results; The ratio of heat transfer coefficient water cooler thermal transmission coefficient of air side is low, so two kinds of coolers that cooling capacity is substantially 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 reaches more than 315kW, reaches more than 500kW abroad.Domestic water cooler adopts single tube structure, to break the situation making cooling water enter into the oil of transformer so there is cooling copper tube in too much cause water cooler, owing to cannot enter into transformer oil by Timeliness coverage water, often make the transformer oil insulation property into water significantly decline, thus cause operating transformer generation serious accident.

Water cooler has that cooling effectiveness is high, low noise advantages, and dual pipe water cooler improves the reliability of water cooler, has been highly suitable for water source area.The dual pipe water cooler technical performance of domestic production and structure are suitable with world level.The freezing problem of cooling water will be considered for cold district.

4, radiating cooler

General employing forced air cooler or water cooler are as the heat-exchange device of large-scale, super-huge oil-filled transformer, and these two kinds of cooler cooling effectivenesss are high.But because oil pump and blower fan run without interruption, therefore there is the shortcomings such as noise is large, the subsidiary engine proportion of goods damageds are high, maintenance workload is large.For solving above-mentioned contradiction, Europe has occurred that one is called 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 simultaneously, and when transformer load rate is about 50%, gilled radiator is in oil state self cool and runs; When transformer load rate reaches about 75%, start blower fan, gilled radiator is in the air-cooled operation of oil state; When transformer at full capacity time, start oil pump and put into operation, drop into oil pump strong oil wind cold type and run.

Be not difficult to find out, in order to maintain preferably heat dispersion, above-mentioned transformer is all adopt foreign compulsion heat radiation, and adopt natural heat dissipation often because the topology layout of its box-type substation self 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 cause cost of manufacture and maintenance difficulties all to have increase, in addition above-mentioned all kinds of supplemental heat rejected facility is low for environment versatility, often because environment limit residing for box-type substation, the thermolysis of its best cannot be played, cannot be suitable for what is more or completely.

To sum up state, there are the problems such as volume is large, maintenance inconvenience, natural heat dissipation poor performance, environmental suitability difference in box-type substation in the market, this also makes box type transformation stand in the popularization of China by restriction to a certain extent.
