Abstract
The utility model discloses a ventilator for a transformer substation, comprising three blades of the same structure, wherein the section of the blade is trapezoidal and is provided with an opening at a long bottom edge; one side of the one blade extends to the opening at the long bottom edge of the other blade symmetrically; and the folds at the opening of the blades are inclined to the short bottom edges at an angle of 10 to 30 DEG. In the utility model, the problem that granular sands enter the box of the transformer substation with the wind to bring hidden dangers to the normal operation of the electrical equipment in the box in the prior art is solved; by splicing three blades with the same structure into a wind inlet, the granular sands and other sundries entering the box of the transformer substation are greatly reduced through the folds on the blades, so that the safe operation of the transformer substation is ensured.
Description
Technical field
The utility model has related to a kind of transformer station and has used ventilation unit, belongs to transformer station's technical field.
Background technology
Transformer station's product is the transformer station that integrates many power equipments such as high pressure, low voltage switchgear and power transformer; Because of it has many advantages such as floor space is little, cost of investment is low, integrated level is high, scheme is flexible, in electric power system, obtain application more and more widely.
In transformer station's product; Because the caloric value of assembling and power equipment wherein is very big; Thereby the heat in the transformer station box is discharged is a requisite process, general perforate on the casing of transformer station, and the mode that ventilation unit is installed in perforate realizes.
But the device of existing ventilation is carrying out in the aeration-cooling process the power equipment in the casing, and a large amount of particle sandstone can enter in the transformer station box thereupon, stays hidden danger for the normal operation of the power equipment in the casing.
The utility model content
The utility model technical problem to be solved provides a kind of transformer station and uses ventilation unit, and power equipment effectively stops the particle sandstone to get in aeration-cooling in to transformer station box, has guaranteed the safe operation of transformer station.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of transformer station uses ventilation unit; Comprise 3 blades that shape is identical; Said blade profile is a trapezoidal shape, and long base opening, and one of them side of two blades is the long base opening part that symmetry shape stretches into another blade.
Aforesaid a kind of transformer station uses ventilation unit, it is characterized in that: the flanging of the opening part of said blade tilts to short base direction, and the angle of inclination is the 10-30 degree.
Aforesaid a kind of transformer station uses ventilation unit, it is characterized in that: the angle of inclination of the hypotenuse of said blade is the 20-70 degree.
Aforesaid a kind of transformer station uses ventilation unit, it is characterized in that: said blade is an aluminum alloy material.
The beneficial effect of the utility model is: be spliced into an air inlet through 3 identical shaped blades, utilize flanging setting on the blade to significantly reduce foreign material such as particle sandstone and get in the transformer station box, guaranteed the safe operation of transformer station.
Description of drawings
Fig. 1 is the structural representation of a kind of transformer station of the utility model with ventilation unit.
Embodiment
To combine Figure of description below, the utility model will be further described.
As shown in Figure 1, a kind of transformer station uses ventilation unit, comprises three blades 1 that shape is identical; Said blade 1 cross section is a trapezoidal shape, and long base opening, and one of them side 3 of two blades 1 is the long base opening part that symmetry shape stretches into another blade 1; The flanging 2 of the opening part of said blade 1 tilts to short base direction, and the angle of inclination is the 10-30 degree, is preferably 20 degree; The angle of inclination of the hypotenuse 2 of said blade 1 is the 20-70 degree, is preferably 45 degree.
In use, this ventilation unit is installed in transformer station's wind inlet channel grid before, wind is got into before the grid of air channel at first through this ventilation unit.Wind is from getting between two of the ventilation unit symmetrical blades 1, and when striking the 3rd blade, part particle sandstone can be slipped to outside the ventilation unit because of the minor face plane of deadweight along the 3rd blade.A part of particle sandstone in addition block the back landing along the flanging that is connected edge surface after the inner surface of the 3rd blade continues to move with the wind, have the particle sandstone hardly thereby realized getting in the wind of transformer station box air channel grid.
Said blade 3 is an aluminum alloy material, and skin-friction force is less, the sandstone landing of being more convenient for.
In sum, a kind of transformer station that the utility model provides uses ventilation unit, can effectively stop the particle sandstone in the wind to get in the transformer station box, has guaranteed the safe operation of transformer station.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range by appending claims and equivalent circle thereof.
Claims (4)
