Description
Technical field
The utility model belongs to transformer technology field, more particularly, to a kind of dry-type transformer increasing heat dissipation effect.
Background technology
Currently used for the dry-type distribution transformer of high voltage occasion, by the molding high-tension coil of poured with epoxy resin with it is all kinds of
The low-voltage coil of form is the individually enough part being separated from each other, therefore the structure of this kind of dry-type transformer is relative complex, volume also phase
It answers bigger than normal.And existing dry-type transformer relies primarily on cross-ventilation and is cooled down, cooling effect is poor, not resistant against high temperatures.More have
In order in tap is also cast in so that the thickness of this part epoxy has reached 50-60 millimeter, and this thickness makes interior
The ability of portion's coil natural heat dissipation is very poor, and fever phenomenon is be easy to cause in high power work, and influencing the normal of equipment makes
With, while can also bring danger.Therefore, it is necessary to be improved.
Invention content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of doing for increase heat dissipation effect
Formula transformer, it has the characteristics that the good heat dissipation effect of winding and bossy body tap portions and has sound insulation value.
To achieve the goals above, technical solution used by the utility model is：A kind of dry type increasing heat dissipation effect
Transformer, including pedestal, the iron core being installed on the pedestal and the three-phase windings being set on the iron core, per phase winding packet
Include the low pressure winding and high-voltage winding being arranged from inside to outside, further include by every phase winding low pressure winding and high-voltage winding solidification
The epoxy resin poured body being integrated is arranged in the epoxy resin poured body and between low pressure winding and high-voltage winding
There is longitudinal ventilation air flue A；It is also formed with bossy body in the epoxy resin poured body, is provided on the bossy body several
A tap is additionally provided with several longitudinal ventilation air flue B to radiate to the winding on the bossy body；The bottom
The wind turbine for corresponding to three-phase windings respectively is provided on seat；The sound panel around three-phase windings is additionally provided on the pedestal.
The longitudinal ventilation air flue B is symmetrically arranged in the both sides of the tap.
