Description
Technical field
The present invention relates to a kind of transformator, be specifically related to the dry-type transformer coil of a kind of perfect heat-dissipating.
Background technology
In dry-type transformer, due to the structure and material of transformator self itself, reaching correlation technique
On the premise of energy, the temperature rise of transformator is designed to the lowest, and transformator runs the safest, the least to the destruction of insulant, transformation
The device life-span is the longest.So the temperature rise design of transformator is particularly important, and the means taked are to arrange ventilation in the middle of coil
Air flue, strengthens the convection current in coil of air, and the lowest heat dissipation by low-voltage coil generation is gone out, it is ensured that coil is at one
Reasonably run at temperature.The conventional method forming heat radiation air flue technique, when coil winding every certain in coil
Designed distance places a number of H level fiberglass " work " stay, self-assembling formation heat radiation air flue.This glass fibre " work " supports
Though bar is widely used, but it has certain sectional area, accounts for 10%～20% of air flue area in the airways region of coil
Long-pending, that extreme influence air flue ventilates effect, the area of dissipation usage factor of the air flue being reduces.The leading of fiberglass stays simultaneously
Hot property is poor, also contributes to the radiating effect of transformer coil.
Summary of the invention
The present invention is directed to the problems referred to above and propose the dry-type transformer coil of a kind of perfect heat-dissipating, greatly improve ventilation
The effect of heat radiation, area of dissipation usage factor reaches more than 95%.
Concrete technical scheme is as follows:
A kind of dry-type transformer coil of perfect heat-dissipating, including core limb and coil, coil surrounds outside core limb,
Four of core limb are equipped with some aluminium alloy stays between outer wall and coil, described aluminium alloy stay is rectangular structure, aluminum
Alloy stay is provided with the first heat radiation air flue, the first heat radiation air flue connection core limb and coil, wall thickness of described aluminium alloy stay
H1 is 0.7 1mm, forms second between two the adjacent aluminium alloy stays being arranged between same core limb outer wall and coil
Heat radiation air flue, the width L2 of the second heat radiation air flue is 60 80mm.
The dry-type transformer coil of above-mentioned a kind of perfect heat-dissipating, wherein, if being longitudinally provided with on described aluminium alloy stay wall
Dry passage.
The dry-type transformer coil of above-mentioned a kind of perfect heat-dissipating, wherein, described passage is truncated cone-shaped structure, passage
Top diameter is d1, and base diameter is d2, d1=1.5*d2.
The dry-type transformer coil of above-mentioned a kind of perfect heat-dissipating, wherein, the outside cladding of described aluminium alloy stay one layer is absolutely
Edge layer.
The invention have the benefit that
Stay thickness of the present invention is 0.7 1.0mm, and to ensure that this square tube has enough intensity, when placing, stay is tight
Between patch core limb and coil, and use insulator separation, it is ensured that electric insulation；Spacing 60mm between aluminium alloy stay
80mm, forms the second heat radiation air flue, forms the first heat radiation air flue so that taking of the stay of formation air flue in the middle part of aluminium alloy stay
Area is also obtained by, and accounts for 1%～2% area of air flue area in the airways region of coil, greatly improves air flue and leads to
The effect of wind, makes the area of dissipation usage factor of air flue reach more than 95%.Aluminium alloy stay simultaneously, is metal material, heat conduction
Performance is better than texture of coil copper material, and heat conductivility is more preferable.
Transformator has heat resistance and flame-retardancy requirements to insulant, thus uses aluminium alloy stay to fully meet.
Transformator uses aluminium alloy stay, lightweight, cheap, coil entirety temperature rise and the coil of fiberglass stays
Comparing reduction by 5 10K, coil strength is good, and fire resistance is good, adds transformer life.
The setting of passage, further increases heat dispersion, and the structure of passage is arranged, and has further speeded up heat radiation speed
Degree.
