Technical Field
The utility model relates to a transformer technical field, in particular to low energy consumption totally enclosed oil-immersed air cooling power transformer.
Background
With the development of the country, the life of residents is continuously improved, more and more household appliances are used, the power load is increased rapidly, and particularly in the peak period of power utilization, the transformer is frequently operated in an overload mode. The overload operation of the transformer can cause the temperature of the transformer main body to rise suddenly, and if the temperature of the transformer main body is not controlled in time, the service life of the transformer can be shortened for a long time. Meanwhile, if the capacity of the transformer is increased to meet the requirement of improved power load, the no-load loss of the transformer is correspondingly increased, so that the initial input cost is increased, the power consumption cost is increased in the power consumption valley, resources are wasted, and the power consumption of the transformer is controlled.
The existing oil-immersed power transformer relies on oil cooling for cooling, but when the power of the transformer is large, the volume and the weight of the transformer are increased by only depending on oil for heat dissipation. When the transformer runs under overload, the heat dissipation requirement of the transformer cannot be met if the transformer completely depends on oil liquid for heat dissipation, so a certain supplementary heat dissipation mode is also necessary.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a low energy consumption totally enclosed oil-immersed type air cooling power transformer, mainly used solve the not enough problem of oil-immersed type power transformer fluid heat-sinking capability to and solve the extravagant problem of resource that transformer self extra power consumption caused.
The above technical problem of the present invention can be solved by the following technical solutions: the oil tank comprises an oil tank, the fluid of oil tank soaks in and is equipped with wire wound core, the outside of oil tank is equipped with air interlayer's the outside is equipped with the soundproof cotton layer the outside on soundproof cotton layer is equipped with electromagnetic radiation shielding layer, the outside on electromagnetic radiation shielding layer is the shell, the top of shell is fixed with reserve tank, reserve tank bottom is through oil pipe and inside oil tank switch-on, still be equipped with the fluid in the aforementioned reserve tank of fuel tap control on the oil pipe the top of shell still is fixed with unpowered ventilator, unpowered ventilator bottom is connected with the breather pipe, the bottom of breather pipe with be located the inside U type return bend of oil tank is linked together, the bottom of U type return bend also is connected with breather pipe and external intercommunication.
Preferably, the vent pipe is provided with an air inlet communicated with the air interlayer, so that air in the air interlayer is continuously replaced, and the cooling effect of the air interlayer is fully ensured.
Preferably, the other five surfaces of the shell except the bottom surface are sprayed with heat insulation coatings. Isolate a part of high temperature air and sunlight heat source.
The utility model has the advantages that: the unpowered ventilator which does not need to consume energy is utilized to discharge the heat inside the transformer, so that the energy consumption of the whole transformer is reduced while the heat dissipation of the internal oil liquid is assisted. Meanwhile, the outer side of the transformer main body is also provided with a soundproof cotton layer, so that the noise of the transformer is reduced. And the outermost side of the transformer main body is provided with an electromagnetic radiation shielding layer, so that the electromagnetic radiation of the transformer can be effectively isolated.
