Description
Technical field
The present invention relates to a kind of oil-immersed type transformer more particularly to a kind of high efficiency and heat radiation oil-immersed type transformers.
Background technique
Transformer (Transformer) is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, impedance transformation, is isolated, is steady at current transformation
Press (magnetic saturation transformer) etc..Can be divided into, according to use: (electric furnace becomes, rectification becomes, power frequency examination for power transformer and special transformer
Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, mutual inductor etc.).Transformer during the work time, so that oil temperature increases in fuel tank, leads to inside
Device failure reduces transformer service life.Existing oil-immersed type transformer cooling method is directly welded using heat dissipation sheet mode, cooling fin
It connects in the front and rear sides of transformer, and cooling fin is vertical with fuel tank sidewall, heat dissipation effect is poor.Oil-immersed type transformer is generally fixed to height
Sky needs to sling installation, and conventionally employed Suspension hook structure is inconvenient when slinging, and is easy sliding, and risk is high.
Summary of the invention
In view of the foregoing drawbacks, the purpose of the present invention is to provide a kind of structure is simple, good heat dissipation effect guarantees oil immersion transformation
Device can work normally, and prolong the service life, and lift by crane a kind of highly-safe high efficiency and heat radiation oil-immersed type transformer.
Thus the technical scheme adopted by the invention is that:
Including rectangular fuel tank, installation is cored in the fuel tank, and winding is equipped on the outside of the iron core, and the front and back of the fuel tank is left
Right surrounding is equipped with oil cooler, and the oil cooler includes upper chamber and lower oil chamber, if passing through between upper chamber and lower oil chamber
Dry heat-dissipating pipe connection is equidistantly equipped with several cooling fins, the oil inlet of upper chamber and fuel tank side on the heat-dissipating pipe from top to bottom
The connection of wall top, the oil outlet of lower oil chamber are connect with fuel tank sidewall lower part, and the winding upper end is equipped with primary cable terminal and height
Conductor terminal is pressed, annular hoisting ring is equipped on the downside of the quadrangle of the fuel tank upper end, the tank bottoms are equipped with pony sill.
As a further improvement of the above technical scheme, the heat-dissipating pipe is the straight type heat-dissipating pipe of red metal.
As a further improvement of the above technical scheme, the cooling fin is fine copper cooling fin, the surface of the cooling fin
On offer blinds fin.
As a further improvement of the above technical scheme, the pony sill is that two parallel steel feet framves are constituted, steel feet frame
Connecting plate is equipped with tank bottoms junction.
As a further improvement of the above technical scheme, it is cased with high-tension insulating bushing on the high-voltage conducting wires terminal, it is described
Low-voltage insulation casing is cased on primary cable terminal.
The invention has the advantages that
The configuration of the present invention is simple, by using the oil cooler of this structure so that not close to mailbox side wall oil cooler other
Three faces can receive extraneous wind, and can receive natural heat dissipation, greatly improve heat dissipation effect, guarantee oil-immersed type transformer
Internal components work normally, so that service life is extended, using the annular lifting lug being arranged on the downside of the quadrangle of fuel tank upper end, lifting side
Just, security performance is high.
