Embodiment
A kind of heat abstractor that is used for dry-type transformer as shown in Figure 1 includes heat abstractor body 1, and its unusual part is: the top of the heat abstractor body 1 that the present invention adopted is arranged with ventilating opening 2.Further, be provided with driving blower fan 3 in the ventilating opening 2.Simultaneously, consider with dry-type transformer and can firmly and effectively combine assembling, be provided with auxiliary stand 4 in the bottom of heat abstractor body 1.
In conjunction with the present invention's one preferred implementation, supply with in order to realize power supply, simultaneously also for fear of the in disorder situation of cabling occurring, heat abstractor body 1 is provided with threading hole.And, be outward extended with power supply wiring 5 in this threading hole.
Again further,, promote the effect of heat radiation, be wavy arrangement between the ventilating opening 2 of employing in order to improve area of dissipation.Like this, such as being provided with under the prerequisite of two ventilating openings 2 side by side, adopt the mode of wavy arrangement can arrange three.Simultaneously, drive blower fan 3 work in the time of can avoiding side by side mode and disturbing flow occurs.
The placement of considering heat abstractor is stable, can adjust the angle of laying of heat abstractor according to the mode of reality, is connected with base support 7 through adjustment screw 6 on the auxiliary stand 4.Like this, can also promote the placement height of heat abstractor, when avoiding work with the unnecessary resonance of lay down location generation.And, be distributed with on the base support 7 and regulate fixing hole 8, can install various auxiliary pad pin additional with this.Perhaps, can connect other positioning components through regulating fixing hole 8.
From implementation process of the present invention, directly air-flow is blown in the winding air channel with 90 degree elevation directions, and the direction of adjustable when mounted rectification campaign fan.
Through above-mentioned character express and combine accompanying drawing to find out, adopt the present invention after, air-flow only blows to Transformer Winding, the situation at other positions of part air flow direction can not occur, has promoted cooling effectiveness.
Specifically:
(1) for flabellum balance and useful life
Because the motor spindle of cross flow fan and the central point of fan frame bearing pedestal are difficult for keeping concentric position in group, and after causing flabellum axle two ends to be fixed at above-mentioned 2, can produce the partial eccentricity phenomenon immediately; Therefore under the situation of flabellum high speed rotating, bearing very easily takes place damage unusually, flabellum is not only long but also heavy simultaneously; Pivoting moment is bigger, also is prone to produce the rotation unbalance vibration, causes bearing to quicken loss; Fan life also will shorten, and pivoting moment of the present invention by contrast is less, and the distance between flabellum and the fixed pivot is shorter; Therefore, running balance and be much better than cross flow fan useful life certainly.
(2) about operating reliability
Cross flow fan is a strip, and volume is relatively large, generally all is every two cooling fans (in the high-pressure side, in low-pressure side) of installing mutually, and promptly every three-phase transformer is equipped with six cross flow fans, just in case fault of cooling fan wherein.Then the fan cooled ability of this phase winding can reduce half relatively, brings hidden danger for the safe operation of transformer.Volume of the present invention by contrast is less; Can send out six typhoon machines (on average being installed in transformer high-low pressure both sides) though the cooling blower sum is cross-flow three times by every dress mutually; But its gross power is still little than six cross flow fans; When supposing to have a typhoon machine fault, it is about 1/6 that the fan cooled effect of this phase winding reduces, the unlikely safe operation that influences integrated transformers.
(3) cooling effect
The air-flow of cross flow fan blows into crosswind road inside and outside the winding with about 45 degree elevation directions; And often cause invalid sinuous flow in shunting radially; Make the useful axial flow of winding heat radiation is reduced; The present invention directly is blown into air-flow in the winding air channel with 90 degree elevation directions, so the fan of identical cooling capacity comes comparison, its efficient is far above cross flow fan.
(4) mode of connection
The cross flow fan volume is bigger, and usually earlier with frame fixation distribution again, its terminal board is exposed outside simultaneously; Wiring path is uneven; Therefore neat from being difficult in appearance the circuit arrangement, need voluntarily during wiring, the possibility of wrong line will take place then if run into the fan electric control unit by the client.The present invention is less because of volume, and available semi-enclosed fan chest is fixed, and all is hidden in the case for the power supply wiring place of each cooling blower, so profile is quite attractive in appearance.
(5) position adjustment
Be installed in the transformer of different size; Cross flow fan needs the special relative position of considering between adjustment fan body and the winding; Air-flow is got into best angle, but, need to strengthen in addition the transformer height during fan assembly insufficient space when running into the capacity smaller transformer; So not only increase material cost, more increase the height space of transformer.The present invention vertically is positioned over the winding bottom, so air-flow can directly get into the air channel, because volume is little, also need not to increase the height of transformer when being installed on the transformer than low capacity.
(6) structure is firm and attractive in appearance
Transformer carries out distribution, when assembling delivering client or distribution board manufacturer; Inconvenient operation in the time of often because of installation shell or back panel wiring, the cooling fan shell of transformer often just becomes operating personnel's of short duration stance, and the shell of cross flow fan does not have special anti-weighted design; Often therefore be out of shape; Cause flabellum to rotate, to this situation, the printed words that only on the cooling fan shell, indicate (forbidding trampling) usually are to avoid damaging fan structure.The present invention is directed to said circumstances and take the design of hommization, make the enough heat abstractor bodies of intensity especially, except that can make combination of fans attractive in appearance, the distribution workmen also is provided a good foothold.
(7) maintenance speed
Because the production of cross flow fan is not general, and the different size versatility is relatively poor, in case fan failure be difficult for changing immediately the situation generation of same specification product, and its maintenance is difficult.To produce manufacturer many and complete in specifications because of the present invention, exchange to give birth to highly, so the client can keep in repair or change voluntarily, very easily solve above-mentioned difficulties.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
