Description
Technical field
The utility model is related to electrical facility technical field more particularly to a kind of improved power transformers.
Background technology
With the fast development of society, either civilian or industrial electricity is all incrementally increasing, therefore various transformation
Device is seen everywhere.The running temperature of transformer has prodigious relationship with its service life, in order to reduce cost of manufacture, generally uses oil immersion
Formula transformer fills insulating oil in the fuel tank of transformer, and installs cooling fin outside fuel tank, reaches the mesh to cool
's.Existing high-power transformer is equipped with temperature indicating device, can directly observe its running temperature to take cooling in time
Measure.But there is no temperature indicating devices on the miniature transformer that vast villages and small towns directly power to terminal user, and these
Transformer is in mostly in outdoor adverse circumstances, if the heat dissipation effect of transformer is bad, is easily reduced transformer component
Service life, while there is also great security risks to its safe operation.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of improved power transformers, it is intended to solve existing skill
Art Transformer heat dissipation effect is bad, there is technical issues that.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of improved power transformer includes the fuel tank full of insulating oil, transformer body, institute is equipped in the fuel tank
It states the front side of fuel tank and rear side is equipped with shell, Packed interlayer is set between the shell and the outer wall of the fuel tank, it is described
The outside of the cooling medium of filling in interlayer, the shell is equipped with cooling fin, and the cooling fin is hollow structure, the cooling fin
Inner cavity is connected to the interlayer.
Preferably, it is connected by delivery pump between the front side interlayer of the fuel tank and rear side interlayer.
Preferably, the left side, right side of the fuel tank are equipped with corrugated fins item.
Preferably, the top of the fuel tank is equipped with thermometer, and the thermometer includes thermometer bulb and dial plate, and the thermometer bulb extends
It is contacted with insulating oil in fuel tank, the dial plate is arranged outside fuel tank.
Preferably, the outside of the cooling fin is equipped with fin.
It is using advantageous effect caused by above-mentioned technical proposal：Compared with prior art, the utility model by
It is equipped with shell outside the front and back sides of fuel tank, makes to form the interlayer that can accommodate cooling medium between shell and fuel tank outer wall, together
When in the outer wall of shell, hollow cooling fin is set, so that cooling medium is filled in interlayer and cooling fin, expand significantly
Heat dissipation area ensure that the heat dissipation effect of transformer, and then extend the service life of transformer.

Referring to Fig. 1,2, a kind of improved power transformer provided by the utility model includes the fuel tank 1 full of insulating oil,
Transformer body is equipped in the fuel tank 1, the front side of the fuel tank 1 and rear side are equipped with shell 2, the shell 2 and the oil
Packed interlayer 3 is set between the outer wall of case 1, cooling medium is filled in the interlayer 3, and the outside of the shell 2 is equipped with heat dissipation
Piece 4, the cooling fin 4 are hollow structure, and the inner cavity of the cooling fin 4 is connected to the interlayer 3.
As a kind of preferred structure, it is connected by delivery pump 5 between the front side interlayer 3 and rear side interlayer 3 of the fuel tank 1.
Front and back interlayer is connected to by medium delivery pump and pipeline, and cooling medium stream is made to move up, and then accelerates the cooling to transformer, is received
Good cooling-down effect.
In a specific embodiment of the utility model, left side, the right side of the fuel tank 1 are equipped with corrugated fins item 6.
Auxiliary temperature-reducing is carried out to the left and right sides of fuel tank using corrugated fins item.
In an optimal technical scheme of the utility model, the top of the fuel tank 1 is equipped with thermometer 7, the temperature
Meter 7 includes thermometer bulb and dial plate, and the thermometer bulb is extended in fuel tank 1 and contacted with insulating oil, and the dial plate is arranged outside fuel tank 1.
The temperature that transformer can be monitored in time using thermometer, is conveniently taken effective cooling measure, high temperature is avoided to make transformer
At damage.
Above-mentioned technical proposal is advanced optimized, the outside of the cooling fin 4 is equipped with fin 8.It can be further by fin
Expand heat dissipation area, strengthens heat dissipation effect.
In conclusion the utility model has the advantages that simple in structure, good cooling effect, pass through the interlayer before and after fuel tank
