Technical field
The invention belongs to technical field of electric equipment, relate to a kind of dry type transformer clamp hot-air guiding device.
Background technology
As the transformator of one of power transmission and transformation substantial equipment, it is in running, due to the existence of the flowing of each coil-conductor electric current and electromagnetic field, can produce electric energy loss, mainly load loss, open circuit loss and added losses.These losses translate into heat and are delivered in surrounding medium, thus causing transformator heating and temperature to raise.But along with the increase of transformer capacity, leakage magnetic flux increases, and corresponding stray loss increases；The size of transformator and capacity increase and disproportionate cause local stray loss to increase；High-power transformer electric current is big, particularly has circulating current to pass through also to increase accordingly added losses etc. between each parallel conducting wire of low pressure winding.
Therefore, the difficulty that distributes of transformator generation heat increases with the increase of volume and capacity, it is necessary to takes additional heat measure to reduce temperature rise, and takes additional heat measure will accordingly increase the added losses of transformator.
Prior art is to arrange axial ducts in transformer coil pour mass, makes inside transformer gas circulate, and heat distributes.But it has the drawback that only axial ducts heat radiation is fast not enough, and especially for the jumbo transformator of large volume, radiating effect is inconspicuous, and in two of axial ducts exports, it is provided with cushion block is connected with folder, cushion block meeting blocking portion air channel.
Usual resins casting dry type transformer in order to clamp iron core be generally adopted channel-section steel interfix in iron yoke both sides tension mode.Owing to now upper clamping piece off-line circle is relatively near, it is unfavorable for the circulation of hot-air.
