Abstract
The utility model relates to a transformer cooling fan which comprises a wind wheel and fixed connecting plates arranged on the two sides of the wind wheel. A motor is fixed on the fixed connecting plates and drives the wind wheel through a shaft sleeve connector, an air inlet baffle which is folded into 90 degrees is arranged on an air inlet of the wind wheel, and a protecting net is arranged on an air outlet of the wind wheel. The transformer cooling fan is characterized in that a plurality of rows of long strip holes which are evenly distributed are formed in the air inlet baffle, wherein the distance between every two long strip holes is 2-2.5mm, and a wind cutting and guiding plate is mounted between the air inlet baffle and the protecting net. According to the transformer cooling fan, the structure is simple and firm, the size is small and exquisite, occupied space is little, the advantages of being large in air outlet volume, high in heat dissipation efficiency, low in noise and production cost and the like are achieved, and the transformer cooling fan can be widely used for cooling rectifying dry type transformers and wind power dry type transformers.
Description
Technical field
The utility model relates to the enterprising sector-style of dry-type transformer cold equipment, particularly commutation dry-type transformer, wind-powered electricity generation dry-type transformer cooling blower used.
Background technique
At present, the intake grill that tradition is applied to the cooling blower on dry-type transformer is all to adopt two aluminum alloy material to be combined into 90 ° as the intake grill baffle plate, vertically strikes out the bar hole air intake on every aluminium alloy plate with punching equipment.In actual generative process due to technique and properties of materials, generally need remaining 4～5mm between the bar hole of aluminum alloy material and hole, to guarantee rigidity and intensity, but so, remaining part has taken larger area, make the corresponding minimizing of air intake space, cause the air quantity of cooling blower little, radiating effect is poor.And the large cooling blower of air quantity can only be realized by the volume that increases product.Cause the commutation dry-type transformer that can't meet small space, the heat radiation requirement of wind-powered electricity generation dry-type transformer, also increased the weight of cost of production.On the other hand, the fan blade of traditional cooling blower is installed also unreasonable part, has affected to a certain extent the effect of heat radiation.These are especially outstanding in the application of commutation dry-type transformer, wind-powered electricity generation dry-type transformer.
The model utility content
The purpose of this utility model is the deficiency that overcomes above-mentioned conventional art, a kind of narrow space space commutation dry-type transformer, wind-powered electricity generation dry-type transformer transformer cooling fan used of being applicable to proposed, thereby make the large blower fan of blower fan substituted volume of small volume, Wind Volume, greatly save the cost of production of transformer, improved radiating efficiency.
The purpose of this utility model is achieved by the following technical solution: a kind of transformer cooling fan, include wind wheel, be loaded on the fixed connecting plate of wind wheel both sides, motor is fixed on fixed connecting plate, drive wind wheel by the axle sleeve connector, the intake grill place of wind wheel is provided with the intake grill baffle plate that is converted into 90 °, the exhaust outlet place of wind wheel is provided with protective net, it is characterized in that: many platoon leaders cylindrical void that to be formed with spacing on described intake grill baffle plate be 2～2.5mm, evenly arrange, and the wind cutting wind deflector is installed between intake grill baffle plate and protective net.Further, 30～50 road fan blade grooves are arranged on the fan blade fixed plate of described wind wheel, each fan blade is evenly distributed on the fan blade groove with the inclination angle of 35 °～40 °.Described wind wheel bottom is provided with the whirlpool plate of an arc.Described intake grill baffle plate, wind cutting wind deflector, wind wheel, protective net, whirlpool plate are stainless steel.
The structure of design like this has obvious advantage: 1, by improving the intake grill baffle plate and the wind cutting wind deflector being installed, can dwindle the machine volume of cooling blower and increase air output, take up room little; 2, the design of the inclination angle of fan blade has also increased air output, improves radiating efficiency; 3, the design of whirlpool plate can greatly reduce wind and makes an uproar, and while making fan operation, noise is low; 4, complete machine rigidity intensity is good, and is difficult for corrosion.

Embodiment
Referring to Fig. 1-Fig. 2, the transformer cooling fan integral body of the present embodiment is cuboid, the central core parts are wind wheels 12, wind wheel 12 left and right sides are provided with motor fixed connecting plate 2 and bearing fixed connecting plate 14, wind wheel 12 is also installed by axle sleeve connector 6, mandrel connector 10, axle 11 and two fixed connecting plates respectively, and motor 1 is fixed on motor fixed connecting plate 2 and by axle sleeve connector 6 and drives the wind wheel rotation.The intake grill place of wind wheel 12 is provided with the intake grill baffle plate 4 that is converted into 90 °, many platoon leaders cylindrical void 13 that special design is that to be formed with spacing on intake grill baffle plate 4 be 2～2.5mm, evenly arranges, exhaust outlet place at wind wheel 12 is provided with protective net 8, protective net 8 is the strip grid, above protective net 8 and between intake grill baffle plate 4, wind cutting wind deflector 15 also is being installed, is preventing the air quantity phase mutual interference between intake grill and exhaust outlet.Wind wheel 12 is cylindrical shape, fan blade fixed plate Shang You 40 road fan blade grooves, and each fan blade 9 is evenly distributed on the fan blade groove with the inclination angle of 35 °～40 °.Be provided with the whirlpool plate 7 of a circular arc under the bottom of wind wheel 12, the protective net 8 of the wind guiding exhaust outlet that fan blade 9 rotations are produced, play and reduce the effect that wind is made an uproar.Working principle is: drive wind wheel 12 by motor 1, by intake grill baffle plate 4 air intakes, after wind passes through whirlpool plate 7 guiding and noise abatement, by the have wind cutting wind deflector 15 tangent generation cooling air quantity of regulating air outlet angle parallel with wind wheel 12.All critical pieces of the present embodiment all adopt stainless steel or material to make, and make complete machine have fabulous anti-corrosion capability, and the processibility of stainless steel material especially is applicable to the machine shaping of the little spacing strip hole 13 of intake grill baffle plate 4 simultaneously.
Certainly, only enumerated a kind of preferably mode of execution here, the protection category that other is equal to, structure roughly the same all should belong to this patent, repeat no more here.
