Abstract
The invention belongs to the field of transformers, and particularly relates to radiating airway devices for a transformer winding. The radiating airway devices of the transformer winding are evenly distributed between the outside and the inside of the winding and are arranged at intervals. The radiating airway devices for the transformer winding are characterized in that each radiating airway device comprises an arc face supporting the outside of the winding, a plurality of aluminum support plates pressing the inside of the winding and a plurality of upright columns connecting the aluminum support plates and the arc faces, the number of the aluminum support plates and is the same with that of the upright columns, the numbers of the aluminum support and the upright columns are both three, and the upright columns are evenly distributed along the arc surface. The radiating airway devices of the transformer winding are made of non-magnetic materials (aluminum), and the heights of the radiating airway devices of the transformer winding can be set according to the reactance height of the winding. By the radiating airway devices of the transformer winding, arching and deformation of insulation materials can be prevented, so that radiating coefficient of the winding cannot decreased. In addition, hot-flow wind-resistance coefficient is reduced by metal materials, radiating effect is improved greatly, and low-voltage winding temperature rising is decreased by 15K around.
Description
Technical field
The invention belongs to field transformer, particularly relate to a kind of heat transmission gas duct device of Transformer Winding.
Background technology
The many employings of heat transmission gas duct device " work " font insulating stay structure (Fig. 1) of transformer low voltage winding, " work " font stay is supported between the outside of winding and inside.As shown in Figure 2, in coil-winding process, the insulating material part on stay both sides easily arches upward the coil that this stay structure turns to, and arched part is heat conduction hardly, thus takies coil air passage radiating space, and the phenomenon that local is too high appears in the temperature rise of winding.This airway device is provided with some stays, and stay is arranged along interval between winding inside and outside, makes coil discontinuity and causes polygon stressed.
Summary of the invention
The object of the invention is to overcome the problems referred to above, provide a kind of and ensure that the coefficient of heat transfer of winding is not lowered, improve radiating effect, the heat transmission gas duct device of the Transformer Winding of coil uniform force.
To achieve these goals, the technical solution adopted in the present invention is: a kind of heat transmission gas duct device of Transformer Winding, be uniformly distributed in the outside and winding of winding inner between and interval arrange, it is characterized in that: comprise the arc surface supporting winding outside, the some aluminium supporting brackets pushing down winding inside and connect some columns of aluminium supporting bracket and arc surface, aluminium supporting bracket is identical with the number of column.
The heat transmission gas duct device of aforesaid a kind of Transformer Winding, described aluminium supporting bracket and column are respectively 3, and column is uniformly distributed along arc surface.
The heat transmission gas duct device of aforesaid Transformer Winding, described heat transmission gas duct device is made up of non-magnetic voltinism metal material.
The heat transmission gas duct device of aforesaid a kind of Transformer Winding, height and the winding reactance of described heat radiation air flue highly adapt.
The present invention is made by a kind of non-magnetic voltinism material (aluminium), height highly can set according to the reactance of winding, the arc surface of upper end supports the outside of winding, and winding inside is pushed down by three shorter aluminium supporting brackets in lower end, middle by three aluminium sheet upright supports.This airway device in use, there will not be insulating material to arch upward distortion, ensures that the coefficient of heat transfer of winding is not lowered; And metal material reduces hot-fluid air resistance coefficient, and greatly improve the effect of heat radiation, low pressure winding temperature rise decline about 15K, economic effect is obvious.Each airway device is almost adjacent being connected, and make coil uniform force that polygon can not be caused stressed, in application process, practical operation is also comparatively simple.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is the structure chart of existing " work " word stay, Fig. 2 is the existing structure chart that the winding coil of heat radiation stay is housed, from Fig. 1 and Fig. 2, the heat transmission gas duct device of transformer low voltage winding adopts " work " font insulating stay structure (Fig. 1), i.e. " work " word stay 4, the coil that this structure stay turns to as shown in Figure 2, " work " word stay 4 is uniformly distributed between the outside 5a of winding and the inner 5b of winding and interval and arranges, insulating material part in the process of coil winding on stay both sides easily arches upward, arched part 6 heat conduction hardly, take coil air passage radiating space, there is the phenomenon that local is too high in the temperature rise of winding.
Fig. 3 is the structure chart of airway device of the present invention, Fig. 4 is the use schematic diagram of airway device of the present invention for winding coil, according to Fig. 3 and Fig. 4, a kind of heat transmission gas duct device of Transformer Winding, be uniformly distributed between the outside 5a of winding and the inner 5b of winding and interval to arrange, it is characterized in that: comprise the arc surface 1 of the outside 5a of support winding, push down some aluminium supporting brackets 3 of the inner 5b of winding and connect some columns 2 of aluminium supporting bracket 3 and arc surface 1, aluminium supporting bracket 3 is identical with the number of column 2.More preferably, aluminium supporting bracket 3 and column 2 are respectively 3, and column 2 is uniformly distributed along arc surface 1.
The present invention is made by a kind of non-magnetic voltinism material (aluminium), and height highly can set according to the reactance of winding, wherein highly just refers to that the height of coil is equidirectional, i.e. axial height, in the winding process of coil, carries out insulation processing by technological requirement.According to the design needs of transformer, airway device can be designed to different length and width, the length of heat radiation air flue refers to the arc length of heat radiation air flue, the thickness of this device materials can carry out particular design according to the tension force difference of the size of transformer capacity and winding equipment, with the instructions for use of satisfied different Transformer Winding.
The present invention in use, there will not be insulating material to arch upward distortion, ensures that the coefficient of heat transfer of winding is not lowered; And metal material reduces hot-fluid air resistance coefficient, and greatly improve the effect of heat radiation, low pressure winding temperature rise decline about 15K, economic effect is obvious.Each airway device is almost adjacent being connected, and make coil uniform force that polygon can not be caused stressed, in application process, practical operation is also comparatively simple.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops on protection scope of the present invention.
