When transformer station works, the meeting that affects of transformer work and solar radiation constantly produces heat, the generation of heat is risen the temperature in case shell gradually, now extraneous temperature is lower, extraneous cold air can be entered by air inlet, by air inlet, entered in the middle of cooling shell, enter in the middle of cooling shell, entering into the central cold air of cooling shell can contact with the annulus in the middle of cavity, cold air can form the boundary layer that one deck is very thin on the wall of cavity and between annulus, in boundary layer, the flow velocity of fixed surface is zero, from surface more away from flow velocity larger, cold air enters in the gap between annulus, in the middle of groove, flow out, thereby drive annulus to be rotated, annulus can drive rotation axis to be rotated by brace, the fan that makes to be arranged on rotation axis rotates, enter into cold air in the middle of cooling shell also can be from entering in the middle of passage in the middle of case shell simultaneously, fan can carry out mixed flow by entering into cold air in the middle of case shell and the hot-air in the middle of case shell, flowing of air in the middle of simultaneously also can accelerating chamber shell, make air and the transformer of circulation in case shell carry out contact heat-exchanging, the heat of transformer is taken out of, and in air high speed circulation, also the hot-air in case shell can be discharged from air outlet in case shell.
By cross-ventilated principle, utilize cold air to enter into air inlet, and by boundary layer flow effect, the working effect of air is amplified, fan can be rotated fast, drive hot-air and cold air in case shell to carry out mixed flow, and the heat transfer rate who has accelerated coil windings and iron core, the radiating effect of transformer is improved greatly, and the heat simultaneously transformer being discharged has carried out better utilization, has improved the utilization ratio of the energy.
Of the present utility modelly further be set to, be provided with some sinuous flow plates that are cambered surface bending in described case shell, described air inlet is positioned at the below of case shell, and described air outlet is positioned at the top of case shell.
The sinuous flow plate of cambered surface bending is set in case shell, in the time of can making the air-flow of fan in driving case shell circulate, the flow velocity of air-flow is increased, form turbulent flow, accelerated the radiating effect in case shell.
Air inlet is located to the below of case shell, air outlet is located at the top of case shell simultaneously, has been convenient to the heat in case shell to discharge, and has also increased the convection effects of air simultaneously, has promoted operating efficiency.
Further, between described air inlet and cooling shell, be connected with wireway, on described wireway, be provided with drying chamber, in described drying chamber, be placed with drier, a described drying chamber dorsad side of air inlet is provided with some metafiltration nets.
By being arranged on the drying chamber on wireway, moisture in the middle of the air entering from air inlet can be removed, prevent the normal work of the moisture effects transformer that air is central, and drying chamber dorsad a side of air inlet some metafiltration nets are set, the solid particle entering in wireway is filtered, also prevented when air-flow velocity is excessive drier to be brought in case shell.
Further, the interior hollow out of the wall of described wireway has also passed into cooling fluid, and the wall of filter screen perforation wireway contacts with cooling fluid.
In the inside of wireway hollow out, pass into cooling fluid, and filter screen is contacted with cooling fluid, can make the temperature of filter screen reduce, when air enters from air inlet, can reduce the temperature that enters air, cooling effect is promoted greatly.
As concrete technical scheme of the present utility model, described filter screen is made by aluminium alloy.
Because the thermal conductivity of aluminium alloy is better, can make the heat transfer effect between filter screen and cooling fluid increase, the price of aluminium alloy is lower, and has good corrosion resistance, extend the useful life of filter screen, reduced the cost of manufacture of this strong radiating box type transformer substation.
Compared with prior art, the utility model has the advantage of: that utilizes air drives fan to rotate to flow phenomenon and boundary layer flow effect, the radiating effect of transformer is promoted greatly, guaranteed the radiating effect of box-type substation, transformer can be worked for a long time.
