Description
Technical field
The utility model is related to a kind of transformer, and in particular to a kind of dry-type transformer coil of perfect heat-dissipating.
Background technology
In dry-type transformer, transformer itself structure and material in itself due to, reaching correlation technique
On the premise of energy, the temperature rise of transformer is designed to lower, and transformer station high-voltage side bus are safer, and the destruction to insulating materials is smaller, transformation
The device life-span is also more long.So the temperature rise design of transformer is particularly important, and the means taken are in the ventilation of coil middle setting
Air flue, strengthens the convection current in coil of air, low in time that the heat dissipation that low-voltage coil is produced is gone out, it is ensured that coil is at one
Run at rational temperature.The method of conventional formation radiating air flue technique, be in coil winding in coil every certain
Designed distance places a number of H level fiberglass " work " stay, self-assembling formation radiating air flue.This glass fibre " work " support
Though bar is widely used, it has certain sectional area, and 10%~20% face of air flue area is accounted in the airways region of coil
Product, the effect of extreme influence air flue ventilation, the area of dissipation usage factor of the air flue for being reduces.Fiberglass stays are led simultaneously
Hot property is poor, also contributes to the radiating effect of transformer coil.
Utility model content
The utility model proposes a kind of dry-type transformer coil of perfect heat-dissipating regarding to the issue above, greatly improves
The effect of ventilation and heat, area of dissipation usage factor reaches more than 95%.
Specific technical scheme is as follows：
A kind of dry-type transformer coil of perfect heat-dissipating, including iron core column and coil, coil are surrounded outside iron core column
Portion, four of iron core column are equipped with some aluminium alloy stays between outer wall and coil, the aluminium alloy stay is cuboid knot
Structure, aluminium alloy stay is provided with the first radiating air flue, the first radiating air flue connection iron core column and coil, the aluminium alloy stay
Wall thickness H 1 be 0.7-1mm, be arranged on shape between the two adjacent aluminium alloy stays between same iron core column outer wall and coil
Into the second radiating air flue, the width L2 of the second radiating air flue is 60-80mm.
A kind of dry-type transformer coil of above-mentioned perfect heat-dissipating, wherein, if being longitudinally provided with the aluminium alloy stay wall
Dry passage.
A kind of dry-type transformer coil of above-mentioned perfect heat-dissipating, wherein, the passage is truncated cone-shaped structure, passage
Top diameter is d1, and base diameter is d2, d1=1.5*d2.
A kind of dry-type transformer coil of above-mentioned perfect heat-dissipating, wherein, one layer of aluminium alloy stay outside cladding is absolutely
Edge layer.
The beneficial effects of the utility model are：
The utility model stay thickness is 0.7-1.0mm, to ensure that party's pipe has enough intensity, when placing, and support
Bar is close between core limb and coil, and uses insulator separation, it is ensured that electric insulation；Spacing between aluminium alloy stay
60mm -80mm, forms the second radiating air flue, and aluminium alloy stay middle part forms the first radiating air flue so that form the stay of air flue
Area occupied be also utilized, 1%~2% area of air flue area is accounted in the airways region of coil, greatly improve
The effect of air flue ventilation, makes the area of dissipation usage factor of air flue reach more than 95%.Aluminium alloy stay, is metal material simultaneously
Material, heat conductivility is better than texture of coil copper material, and heat conductivility is more preferable.
Transformer has heat resistance and flame-retardancy requirements to insulating materials, thus is fully met using aluminium alloy stay.
Transformer uses aluminium alloy stay, lightweight, cheap, the coil of coil entirety temperature rise and fiberglass stays
Compared to 5-10K is reduced, coil strength is good, and fire resistance is good, increased transformer life.
The setting of passage, further increases heat dispersion, and the structure setting of passage has further speeded up radiating speed
Degree.
