Description
Technical field
The present invention relates to the technical field of transformer refrigeration, and in particular to one kind forces the hydronic big work(of interior guiding oil
Rate high frequency transformer refrigeration system.
Background technology
During transformer station high-voltage side bus, heat caused by the loss in winding and iron core must dissipate away in time, in order to avoid overheat
And cause insulation damages.Because the loss of transformer is proportional to its volume, so with the increase of transformer capacity, its volume
It will increase with loss in the form of core dimensions are three cubed, and the quadratic power increase that external surface area is only sized.Low capacity is become
Depressor, external surface area and the ratio between transformer volume are relatively large, can use self cooling mode, pass through radiation and free convection
Heat is dispersed.And high-power transformer is unshakable in one's determination and winding should be immersed in oil, generally use：Oil-immersed self-cooled, oil-immersed forced-air cool,
The forced oil-circulation type of cooling.
Oil-immersed self-cooled takes heat to oil tank wall and radiating tube with the Effect of Nature Convection of oil, then by pair of air
Spread to lead and distribute heat, it does not have special cooling device.Oil-immersed forced-air cool is on the basis of oil-immersed self-cooled, in fuel tank
Install fan additional on wall or radiating tube, using hair-dryer help cool down, install additional it is air-cooled after can make transformer capacity increase by 30%~
35%.The forced oil-circulation type of cooling is divided to forced-oil-air cooling and cold two kinds of strong profit again, and it is the oil in transformer, utilizes oil pump
Fuel tank is returned again after squeezing into oil cooler；Oil cooler makes the special shape easily to radiate, utilizes fan blowing or recirculated water
Make cooling medium, heat taken away, if this mode oil circulation rate than free convection when improve 3 times, transformer can
The capacity of increase by 30%.Forced oil-circulation Directed cooling mode substantially still belongs to forced oil-circulation type, and its main distinction is
The oil circuit of transformer body part is different, employs certain measure in structure using the transformer of oil circuit Directed cooling（Such as
Add gear oiled cardboard, paper web）Oil is set to be flowed by certain path afterwards；Directed cooling is employed, the cold oil of pumping hole is under a certain pressure
It is admitted between coil, in the oil duct of the oil duct between line cake and iron core, the various pieces of coil can be cooled down, can so improve cooling
Efficiency.
Comparatively speaking：Although forced oil-circulation Directed cooling mode solves oily in common oil cooled transformer fuel tank
Road is more random, and the situation for generally causing the heating of coils in transformers bigger than iron core heating accounting example is improved.In large-scale change
Belong to preferable scheme in depressor cooling application.
But all types of cooling are all not in place there is oil circulation in the market, between coil and iron core, coil
Coil segment cooling oil flow velocity it is little, local area cooling also not yet in effect, some section and wire turn local temperatures of coil are very
It is high.For high-power, high frequency, high-tension transformer, with the requirement to power is increasing, the requirement to volume more and more
It is small, and the contradiction of the capacity of cooling oil and its cooling-down effect is just more obvious in transformer tank, the requirement to more preferable cooling measure is just
It is more urgent.
The content of the invention
More cooling oil, the unconspicuous technical problem of cooling effect are needed for high-power transformer, the present invention proposes one
Kind forces the hydronic high-power high-frequency transformer refrigeration system of interior guiding oil, using primary coil as oil circuit conduit, utilizes
Pressure fuel pump greatly strengthen the circulation rate of inside transformer cooling oil so that each spot temperature of coil and iron core is uniform
Homeostasis, will not because cooling oil water conservancy diversion is not smooth and local temperature is too high, so as to play good cooling effect.
In order to solve the above-mentioned technical problem, the technical scheme is that：One kind forces interior guiding oil hydronic big
Power high frequency transformer refrigeration system, including transformer case, compound coil, oil pump and refrigeration unit, compound coil are wrapped in
On the iron core of transformer, compound coil and iron core are arranged in transformer case, and compound coil includes water conservancy diversion copper pipe and copper cash, copper
Line is wrapped on water conservancy diversion copper pipe, and copper cash is connected with the binding post on the outside of transformer case；The transformer case
Bottom is connected with oil guide pipe, and oil guide pipe is connected with oil pump, and oil pump is connected by oil guide pipe with refrigeration unit, refrigeration unit
It is connected by oil guide pipe with water conservancy diversion copper pipe.
The copper cash is strand copper wire, and copper cash is provided with insulating barrier；Oil guide pipe is copper pipe, and oil guide pipe is externally provided with insulating barrier.
The refrigeration unit is made up of compressor refrigeration system, is fixed on the outside of transformer case.
The refrigeration unit is to be fixed on the heat abstractor on the outside of transformer case.
Use of the invention forces the interior oily circulating cooling mode of guiding to be cooled down, and passes through cooling oil using mozzle in coil
Flowed in coil, and increase refrigeration unit, realized the good cooling effect of high-power transformer, it is cold to have filled up current high-power transformer
But device technique blank, there is localized hyperthermia in eliminating transformer, reduce volume, good cooling results, extend the life-span, save the energy
Deng remarkable result.
