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, relate in particular to a kind of heat transmission gas duct device of Transformer Winding.
Background technology
The heat transmission gas duct device of transformer low voltage winding adopts " worker " font insulating stay structure (Fig. 1) more, and " worker " font stay is supported between the outside and inside of winding.The coil that this stay structure turns to is as shown in Figure 2, and in the coil winding process, the insulating material on stay both sides part arches upward easily, and arched part is heat conduction hardly, thereby take coil air passage radiating space, and local too high phenomenon appears in the temperature rise of winding.This airway device is provided with some stays, and stay is along being provided with at interval between the winding inside and outside, makes the coil discontinuity and causes polygon stressed.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, provide a kind of coefficient of heat transfer of winding that guarantees not to be lowered, to improve the heat transmission gas duct device of radiating effect, the stressed uniform Transformer Winding of coil.
To achieve these goals; The technical scheme that the present invention adopted is: a kind of heat transmission gas duct device of Transformer Winding; Be uniformly distributed between winding outside and the winding inside and setting at interval; It is characterized in that: comprise the some columns that support the outside arc surface of winding, push down the inner some aluminium supporting brackets of winding and connect aluminium supporting bracket and arc surface, the number of aluminium supporting bracket and column is identical.
The heat transmission gas duct device of aforesaid a kind of Transformer Winding, described aluminium supporting bracket and column are 3 respectively, column evenly distributes along arc surface.
The heat transmission gas duct device of aforesaid Transformer Winding, described heat transmission gas duct device is made up of unmagnetized property metal material.
The heat transmission gas duct device of aforesaid a kind of Transformer Winding, the height of described heat radiation air flue and winding reactance highly adapt.
The present invention is made by a kind of unmagnetized property material (aluminium); Height can highly be 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 short aluminium supporting brackets in the lower end, and is middle by three aluminium sheet upright supports.This airway device in use the insulating material distortion of arching upward can not occur, and guarantees that the coefficient of heat transfer of winding is not lowered; And metal material reduces the hot-fluid air resistance coefficient, improves the effect of heat radiation greatly, and about low pressure winding temperature rise decline 15K, economic effect is obvious.Each airway device almost is adjacent linking to each other, and makes that the stressed polygon that evenly can not cause of coil is stressed, and practical operation is also comparatively simple in the application process.
