Description
Technical field
The utility model belongs to transformer technology field, more particularly to a kind of transformer cooling device.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary
Level coil and iron core（Magnetic core）.It is demonstrated experimentally that breakdown voltage increases and is remarkably decreased with surrounding media temperature, with temperature exponentially
Inverse relation.To prevent the temperature rise of transformer from exceeding defined numerical value in operation, in order to avoid reduce its service life and cause to hit
Wear out bad.When the long-term tolerable temperature of insulation is 90~95 DEG C, it normally damages the phase as 20 years or so.And often increase by 3 DEG C when spending,
The life-span of insulating materials will reduce half.
In order to reduce influence of the temperature for transformer service life, transformer needs to cool down place when in use
Reason, although traditional fans drive cooling cost is low, the air of inside transformer is not easy to circulate, and cooling effect is poor, and
Although mini air conditioner cools down good cooling results, power consumption is big, and cooling cost is high.
Therefore, it is very necessary set forth herein a kind of transformer cooling device.
Utility model content
For technical problem existing for existing transformer cooling device, the utility model provides a kind of transformer Cooling dress
Put.
A kind of transformer cooling device, it is characterised in that including cross transformer shell, annular air leaving cover, fan, bonnet,
Air inlet pipe, sealed cylinder, through hole and annular fixing frame；Some annular air leaving covers, institute are installed through screw inside transformer shell
State transformer shell lower end and be provided with some and annular air leaving cover in the sealed cylinder of same axial location, the sealed cylinder
Via the through hole connection annular air leaving cover, an annular fixing frame, the annular are connected with through screw inside the sealed cylinder
One axis vertical fan is installed on fixed mount, a bonnet is threaded with the sealed cylinder lower ending opening, after described
Cover and be connected with the air inlet pipe that a gas outlet is stretched into inside the sealed cylinder.
Preferably, the air inlet pipe stretches out the transformer shell.
Preferably, some annular air leaving cover axiss of pitch are misaligned.
Preferably, the sealed cylinder is made of transparent plastic material.
Preferably, the transformer shell surface is provided with some gas outlets.
Compared with prior art, the utility model has the advantages that：The utility model is simple in construction, using without leaf
Fan is fixed on inside transformer shell, and being rotated using the fan inside sealed cylinder makes the cold air that air inlet mouth of pipe goes out through annular
Air leaving cover sprays into inside transformer, forms strong air flow, accelerates the cooling velocity of transformer, good cooling results, and make
Cause it is cheap, it is both artistic and practical, reduce aging effects of the temperature rise for transformer.

Embodiment
The utility model is described further below in conjunction with accompanying drawing：
Embodiment：
As shown in accompanying drawing 1 to 2
The utility model provides a kind of transformer cooling device, it is characterised in that including transformer shell 1, annular outlet
Cover 2, fan 3, bonnet 4, air inlet pipe 5, sealed cylinder 6, through hole 7 and annular fixing frame 8；Pacify inside transformer shell 1 through screw
Equipped with some annular air leaving covers 2, the lower end of transformer shell 1 is provided with sealing of some and annular air leaving cover 2 in same axial location
Cylinder 6, sealed cylinder 6 connect annular air leaving cover 2 via through hole 7, and an annular fixing frame is connected with through screw inside sealed cylinder 6
8, the vertical fan 3 of an axis is installed on annular fixing frame 8, a bonnet 4 is threaded with the lower ending opening of sealed cylinder 6,
The air inlet pipe 5 that a gas outlet is stretched into inside sealed cylinder 6 is connected with bonnet 4, air inlet pipe 5 stretches out transformer shell 1, Ruo Ganhuan
The axis of pitch of shape air leaving cover 2 is misaligned, and so multilayer cold air will not interfere, and accelerates the speed of radiating, sealing drum
Body 6 is made of transparent plastic material, can clear view internal fan operation conditions, the surface of transformer shell 1 is provided with some
Gas outlet, ensure that air exchanges radiating.
Operation principle
During utility model works, the air inlet of air inlet pipe 5 is located in low temperature environment, low during the high-speed rotation of fan 3
Wet body is drawn into sealed cylinder 6 via air inlet pipe 5, and sealed cylinder 6 connects the annular air leaving cover 2 of bladeless fan via through hole 7,
Cryogenic air is discharged along the annular inwall of air leaving cover 2 to both sides, hot friendship is carried out with the high-temperature gas inside transformer shell 1
Change, some annular axiss of pitch of air leaving cover 2 are misaligned, and so multilayer cold air will not interfere, and accelerate the speed of radiating
Degree, air quickly swaps, and has that radiating rate is fast compared to traditional heat emission fan, the big temperature drop speed of air's temperature difference
Degree is fast, accelerates the cooling of inside transformer temperature, and manufacturing cost is cheap, uses attractive in appearance reliable, small power consumption, energy-conserving and environment-protective.
Using technical scheme described in the utility model, or those skilled in the art is in technical solutions of the utility model
Under inspiration, similar technical scheme is designed, and reaches above-mentioned technique effect, is to fall into protection model of the present utility model
Enclose.
