Description
Technical field
The invention belongs to transformer technology field, be specifically related to dry type transformer for deepwater.
Background technology
Along with the develop rapidly of national economy, electric power has become the indispensable power source of industry-by-industry, and power transformer is also generally used widely in our daily life.But often need application special transformer to meet the requirement of its applied environment in some special industries, if deep water power device is at work for reducing long distance electric power transport loss, just need to adopt high-pressure delivery electric power to destination, then transformation supplies deep water power device on the spot.And existing transformer technology mostly only adapts to the less demanding occasion of insulation environment, although there are some so-called full-sealed transformers, its sealing property is higher relative to conventional environment transformer, can not meet the requirement of safe changing voltage in deepwater environment.
Summary of the invention
The object of the invention is to overcome the deficiency that existing transformer technology can not adapt to deep water height external pressure environmental work, provide a kind of insulation property good and the deep water dry-type transformer had compared with high leakproofness.
For achieving the above object, technical scheme of the present invention comprises iron-core workpiece and coil windings.It is characterized in that: iron-core workpiece is made up of yoke, volume iron core and screw, 3 volume iron cores are vertically set on a horizontal plane, and the line of centres of 3 volume iron core end faces is equilateral triangle; The Y-shaped shape of yoke, its 3 lug bosses are in 120 degree of angles; 2 yokes are clamped in the two ends up and down of 3 volume iron cores, and are fixed as one by 2 yokes at 3 volume iron cores and two ends respectively with 3 screws; 3 groups of coil windings are set on 3 volume iron cores, and the lead-out wire of each coil windings is connected with external cable respectively.The transformer body surface formed after iron-core workpiece installs coil windings, integral sealing is provided with certain thickness insulating barrier.
Described yoke is permeability magnetic material, and 3 lug bosses are all provided with circular hole;
Described volume iron core rolls with non-crystaline amorphous metal coiled material, and center is provided with through hole;
The described insulating barrier arranged at transformer body face seal is integrated poured shaping.
The invention has the beneficial effects as follows: transformer volume iron core system non-crystaline amorphous metal coiled material rolls, and has good ferromagnetism, improves transformer conversion efficiency; Between three-phase coil winding, the distribution in equilateral triangle, effectively utilizes space, reduces overall volume when equal transformer capacity; At transformer fe core body and the casting insulated layer of coil winding arrangement external overall, coil windings lead-out wire and external cable connecting portion are also sealed in insulating barrier, improve the reliability of transformer whole and outside insulation exponential sum work.
