Abstract
The utility model relates to a kind of transformer with hydrologic cycle cooling system, comprise fuel tank, thin conduit, water pump and storage tank, described thin conduit is wrapped on the iron core in fuel tank, be connected to each other between described thin conduit, water pump, storage tank three, and drive cooling water to circulate between this three by water pump.Directly cooled the iron core in transformer by the cold water in thin conduit, its cooling effect is better.
Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of oil-filled transformer with hydrologic cycle cooling system.
Background technology
The type of cooling of oil-filled transformer has oil-immersed self-cooled, oil-immersed forced-air cool, forced oil-circulation.Oil-immersed self-cooled is exactly take heat to oil tank wall corrugated plate with the Effect of Nature Convection of oil, relies on air to dispel the heat.Oil-immersed forced-air cool loads onto fan at tank wall on oil-immersed self-cooled basis, utilizes fan to help cooling.Forced oil-circulation is divided into alopecia areata cold-peace water-cooled two kinds, and it is the oil in transformer, returns fuel tank again after utilizing oil pump to squeeze into oil cooler.This type of cooling be mostly skin cooling, cooling effect has much room for improvement.
Chinese patent 2013.12.18 discloses the utility model that publication number is 203351342U, the oil-filled transformer of what this utility model provided be provided with water circulation cooling device is provided with space and in space, arranges the cooling water pipe of water circulation cooling device between outer wall and inwall, the heat of transformer is taken away by the cooling water in cooling water pipe, the type of cooling of this transformer compared with tradition its cooling water pipe closer to inside transformer, cooling effect is better, but but also do not enter inside transformer all the time and cool, its cooling effect is limited.
Utility model content
The purpose of this utility model is for above problem, and providing can directly to a kind of oil-filled transformer with hydrologic cycle cooling system that inside cools.
In order to realize above object, the technical solution adopted in the utility model is: a kind of transformer with hydrologic cycle cooling system, comprise fuel tank, thin conduit, water pump and storage tank, described thin conduit is wrapped on the iron core in fuel tank, be connected to each other between described thin conduit, water pump, storage tank three, and drive cooling water to circulate between this three by water pump.
Further, the junction of described thin conduit and fuel tank is provided with sealing ring.
Further, described thin conduit has double-decker.
The beneficial effects of the utility model are: directly cooled the iron core in transformer by the cold water in thin conduit, and its cooling effect is better.
Water suction tube bank with the connecting portion of fuel tank are overlapped sealing ring increase fuel tank sealing and avoid the oil in fuel tank to leak from junction.
Thin conduit is set to double-decker, even if wherein one deck occurs that breakage still can have another layer to avoid cooling water leakage in fuel tank as guarantee; In addition, when wherein one deck occurs damaged, can be the breakage of interior pipe or outer tube damage according to the liquid determination of interlayer, thus change targetedly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is fuel tank, and 11 is iron core, and 2 is thin conduit, and 3 is water pump, and 4 is storage tank.
Embodiment
Now with specific embodiment, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.
A kind of oil-filled transformer with hydrologic cycle cooling system of the present embodiment includes fuel tank 1, thin conduit 2, storage tank 4 and water pump 3.Thin conduit 2 has double-deck thin conduit 2 by 10 and forms, and its internal diameter is 3mm, and external diameter is 4mm, and length is 3.5m, 10 suction hoses of thin conduit 2 are wrapped on the iron core 11 in fuel tank 1, the heat produced by iron core 11 is absorbed in the mode directly contacted, thin conduit 2 adopts double-deck reason will increase one deck water pipe exactly and makes still can avoid destroying insulating properties in cooling water leakage oil-feed tank 1 when wherein one deck water pipe occurs damaged as guarantee, in addition, when wherein one deck occurs damaged, can be the breakage of interior pipe or outer tube damage according to the liquid determination of interlayer, concrete method is for judging it is outer tube damage when interlayer liquid for during oil, can judge it is that interior pipe is damaged when interlayer liquid is water, thus change targetedly.
Connecting portion in order to avoid the oil in fuel tank 1 from fuel tank 1 with thin conduit 2 leaks, and the present embodiment overlaps sealing ring on its connecting portion increases its sealing.In the present embodiment, also adopt and connecting portion is arranged at scheme fuel tank 1 case top cover being avoided leakage of oil, be specially drill two holes on case lid, diameter is 16mm, and one is water inlet, and one is delivery port, and two mouth place rubber seal seal.
The present embodiment according to the circulation volume (2.5L) of water choose water pump 3 for opening flow be 3.5L/min, inhale journey 1M, H-Max is 24M, operating voltage 12V, the ASP2015 suction pump 3 of power <42W, and also in order to make cooling water cool better the while of can entering in fuel tank 1 for making the cold water in water tank, choose the water tank that volume is 5L.The delivery port of water pipe is connected with the water sucking mouth water pipe head of pump, and the delivery port of pump is connected with storage tank 4, and the other end of water tank is connected with the water inlet of water pipe.DC power supply is powered to pump.Water valve will be loaded onto in addition, to install and maintenance at the intake-outlet of water pipe and the intake-outlet of water tank.
As shown in Figure 1, jointly form hydrologic cycle cooling system by thin conduit 2, water pump 3 and storage tank 4, cooling water circulates under the drive of water pump 3 between this three.Thin conduit 2 is wrapped on the iron core 11 in fuel tank 1, iron core 11 produce heat by thin conduit 2 be cooled water absorb, and cooling water is driven by water pump 3 and outputs in storage tank 4 and carry out nature cooling, because the moisture storage capacity of storage tank 4 is larger, its temperature be difficult to raise, add nature cooling effect thus make the temperature of cooling water remain on reduced levels make cooling water have continue cooling effect.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
