Abstract

The utility model relates to an air cooling system for a dry type transformer. The system comprises a fan. An air outlet of the fan is connected with an air duct. A plurality of movable tuyeres with adjustable air outlet angles are arranged on the air duct, and are aligned with radiation air passages of each coil winding in a transformer body from a lower part. The fan preferably adopts a centrifugal fan, and the number of the fan is limited to be one or two at most. A partition plate is arranged between the fan and the transformer body. The number of the tuyeres is determined by the number of the coil windings of the transformer. According to the air cooling system, a cooling effect can be improved by over 50 percent, the manufacturing cost and the using cost of the air cooling system are remarkably lowered, and the fan can be conveniently and rapidly replaced and mounted.

Description

The air cooling system of dry-type transformer
Technical field
The utility model relates to dry-type transformer, relates in particular to the air cooling system of dry-type transformer.
Background technology
The air cooling system of existing dry-type transformer mainly is made of the width of cloth streaming blower fan that is installed on each coil windings bottom, directly coil and iron core is dried one to one by blower fan, to reach the purpose that helps the coil windings heat radiation.This structure exists following defective:
1, the blower fan air-out disperses, and can not aim at the heat dissipation channel blowing cooling of coil, and cooling effect is not good;
2, all be provided with a blower fan below each coil, cause using blower fan many, the cost height;
3, do not isolate between blower fan and the coil, need to have a power failure after blower fan damages and change.
The utility model content
The utility model discloses a kind of air cooling system of dry-type transformer, be intended to improve existing existing the problems referred to above of dry-type transformer.
The technical solution of the utility model is as follows:
A kind of air cooling system of dry-type transformer, comprise blower fan, the gas outlet of described blower fan is connected with a guide duct, and described guide duct is provided with a plurality of movable tuyeres of regulating the air-out angle, and described movable tuyere is aimed at the heat radiation air flue of each coil windings in the transformer body.
Further, the preferred centrifugal fan of the type of described blower fan, its restricted number is one, two at the most.
Further, be provided with a division board between described blower fan and the transformer body.
Further, the quantity of described movable tuyere depends on the quantity of transformer coli winding.
The air cooling system of the existing dry-type transformer of contrast, advantage of the present utility model is:
1, because the wind-force that blower fan produces can be lowered the temperature by the heating position of movable tuyere concentrated area aligning coil windings, its cooling effect can improve more than 50%;
2, only adopt, two centrifugal fans at the most, need not a coil windings and dispose a typhoon machine, reduced manufacturing cost and use cost,
3, isolate by a division board between blower fan and the transformer body, install, more ventilating fan is very convenient quick.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram
Mark is followed successively by among the figure: 1, blower fan, 2, guide duct, 3, movable tuyere, 4, the transformer body, 5, division board.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described.
With reference to Fig. 1:
A kind of air cooling system of dry-type transformer comprises blower fan 1, and the gas outlet of blower fan 1 is connected with guide duct 2, and guide duct 2 is provided with three the movable tuyeres 3 that can regulate the air-out angle, the heat radiation air flue of movable tuyere 3 each coil windings from aligned beneath transformer body 4.
Be provided with a division board 5 between blower fan 1 and the transformer body 4.
When transformer was worked, blower fan 1 started, and the wind that blower fan 1 produces is blown into the heat dissipation channel of each coil windings in the transformer body 4 by guide duct 2 and movable tuyere 3.The angle of adjusting activity tuyere 3 can make wind aim at heat dissipation channel more accurately.
Need repairing or more during ventilating fan 1, because effective isolation and the protection of division board 5 are arranged, transformer need not to quit work, but just direct control.

Claims (4)

1. the air cooling system of a dry-type transformer, it is characterized in that, comprise blower fan, the gas outlet of described blower fan is connected with a guide duct, described guide duct is provided with a plurality of movable tuyeres of regulating the air-out angle, the heat radiation air flue of described movable tuyere each coil windings from aligned beneath transformer body.
2. the air cooling system of a kind of dry-type transformer according to claim 1 is characterized in that, the preferred centrifugal fan of the type of described blower fan, and its restricted number is one, two at the most.
