Abstract
The utility model provides a cross-flow cooling fan for a dry-type transformer. The cross-flow cooling fan comprises an air regulation plate and a housing, wherein an air outlet is formed at the upper end of the housing; the air regulation plate is obliquely arranged on the air outlet; the inclination angle between the air regulation plate and the air outlet ranges form 130 degrees to 150 degrees; and preferably, the inclination angle between the air regulation plate and the air outlet is 135 degrees. The utility model has the advantages of simple structure and good cooling effect on the transformer.
Description
Technical field
The utility model relates to a kind of cooling blower, and particularly a kind of dry-type transformer cross-flow type cooling blower belongs to the technical field of dry-type transformer cooling device.
Background technology
Along with the develop rapidly of national economy, its need for electricity also sharply increases thereupon, and generating, nuclear power and the wind-powered electricity generation of country are also in fast development, and the transformer consumption that its power transmission and transformation are used is also increasing considerably.Because dry-type transformer safety, noise is little and extensively be suitable for.Cooling blower is as a very important key member in the dry-type transformer, and its quality and efficient directly influence the efficient and the useful life of transformer.
Dry-type transformer cross-flow type cooling blower comprises air regulating board, housing in the prior art, and described housing upper end is provided with air outlet, and what described air regulating board tilted is arranged on above the described air outlet, and the angle that tilts between described air regulating board and the air outlet is 160 °.Because the angle that tilts between air regulating board and the air outlet is 160 °, the air-out of air outlet is highly lower, wind direction can not be concentrated on the position that transformer need cool off, and therefore, the cooling effect of transformer is relatively poor, thereby has reduced the useful life of transformer.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, dry-type transformer cross-flow type cooling blower that can improve the transformer cooling effect.
In order to solve the problems of the technologies described above, the utility model dry-type transformer cross-flow type cooling blower, comprise air regulating board, housing, described housing upper end is provided with air outlet, described air regulating board is obliquely installed on described air outlet, and the angle that tilts between described air regulating board and the described air outlet is 130 °-150 °.
Above-mentioned dry-type transformer cross-flow type cooling blower, wherein, the angle that tilts between described air regulating board and the described air outlet is 135 °.
The utlity model has following advantage:
Because the angle that tilts between air regulating board and the air outlet is 130 °-150 °, the high air-out of air outlet air-out is highly increased, wind direction is concentrated on the position that transformer need cool off, thereby, improve the cooling effect of transformer, prolonged the useful life of transformer; In addition, because the angle that tilts between air regulating board and the air outlet is 135 °, during the transformer cooling, wind direction concentrates on the position that transformer need cool off more, thereby has further improved the cooling effect of transformer.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, the utility model dry-type transformer cross-flow type cooling blower, comprise air regulating board 1, housing 2, described housing 2 upper ends are provided with air outlet 21, described air regulating board 1 is obliquely installed on described air outlet 21, the angle [alpha] that tilts between described air regulating board 1 and the described air outlet 21 is 130 °-150 °, because the angle [alpha] that tilts between air regulating board 1 and the air outlet 21 is 130 °-150 °, the high air-out of air outlet 21 air-out is highly increased, wind direction is concentrated on the position that transformer need cool off, thereby, improve the cooling effect of transformer, prolonged the useful life of transformer;
In order further to have improved the cooling effect of transformer, in the present embodiment, it is 135 ° preferably with the angle [alpha] that tilts between described air regulating board 1 and the described air outlet 21, because the angle that tilts between air regulating board 1 and the air outlet 21 is 135 °, during the transformer cooling, wind direction concentrates on the position that transformer need cool off more, thereby has further improved the cooling effect of transformer.Through overtesting, when the angle that tilts between air regulating board 1 and the air outlet 21 was 135 °, the frequency that cooling blower started in 24 hours had increased, and move descended 30% total time, transformer is in operation, and has played better cooling effect.
In sum, the utlity model has simple in structure, the advantage of low noise, and good to the transformer cooling effectiveness.
The utility model is not subjected to the restriction of present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
