Abstract
The utility model provides a profiled transposition wire, which solves the problem that thermal diffusivity is poor when the conventional transposition lead is used for a high capacity transformer winding and a middle voltage and low voltage winding. The profiled transposition wire comprises a plurality of flat enameled wires which include square metal conductors coated with insulating layers. The plurality of flat enameled wires are configured in two columns in which the wide surfaces of the flat enameled wires are contacted and are subjected to transposition process with the same turning along a narrow surface on the upper surface and the lower surface of the two columns of flat enameled wires. After that, the two columns of flat enameled wires are wrapped with external insulation layer. The profiled transposition wire is characterized in that, the square metal conductor of the flat enameled wires is a profiled metal conductor provided with a groove on a center of the wide surface. The outside of the profiled metal conductor is coated with the insulating layer.
Description
Technical field
The utility model relates to the production and processing field of transposed conductor, is specially a kind of special-shaped transposed conductor.
Background technology
Transposed conductor is to be combined into enamel-cover copper (aluminium) lenticular wire of certain radical two row that wide face is in contact with one another, on request on two row enameled sheet wires and below do the same transposition turning to along leptoprosopy, and make continuous wrapped winding wire with electrician's insulating paper, grid bundling belt.Current transposed conductor is made up of square metal conductor 4, insulation enamelled coating 5, external insulation layer 6 and middle liner paper 7, see Fig. 1, after the outside coating conventionally of square metal conductor 4 insulation enamelled coating 5, make enameled sheet wire, the enameled sheet wire of certain radical is combined into two row that wide face is in contact with one another, also between two row enameled sheet wires, clamping middle liner paper 7 according to standard-required, then two row enameled sheet wire coated outside insulating papers after permutation and combination or grid bundling belt are as external insulation layer 6.The winding of large-scale power transformer adopts transposed conductor more at present, it can significantly reduce load loss, reduce coiling hotspot temperature rise, promote winding mechanical strength, make structure compacter, and coil processing is easier, but in the time that high-power transformer moves, when the heat radiation of transposed conductor mainly relies on coiling transformer, reserved oil duct gap is carried out coolingly, and its cooling effect is poor, and when coiling transformer, winding volume has also been strengthened in reserved oil duct gap, increases manufacturing cost; In addition, in the time that transposed conductor is applied to transformer mesolow winding wire, because mesolow winding inter-turn voltage is not high, electric current is large, sectional area is large, thereby require transposed conductor to there is better thermal diffusivity, but current transposed conductor cannot meet its heat radiation requirement.
Summary of the invention
For the problems referred to above, the utility model provides a kind of special-shaped transposed conductor, the poor problem of heat dispersion when it can solve existing transposed conductor for high-power transformer winding and mesolow winding.
Its technical scheme is like this, it comprises some enameled sheet wires, described enameled sheet wire comprises square metal conductor, described square metal conductor is coated with insulating barrier, described some enameled sheet wires are combined into two row that wide face is in contact with one another, and on described two row enameled sheet wires and below do the same transposition processing turning to along leptoprosopy, rear two row enameled sheet wire outer wrap are processed in transposition external insulation layer, it is characterized in that: the square metal conductor of described enameled sheet wire is the special-shaped metallic conductor that wide center of a side has Baltimore groove, the outside surrounding of described special-shaped metallic conductor is coated with described insulating barrier.
It is further characterized in that:
The described Baltimore groove of wide of two upper and lower adjacent enameled sheet wires of the described enameled sheet wire of every row is just to arranging;
Described insulating barrier comprises insulation enamelled coating and self-adhesion enamelled coating, and described insulation enamelled coating is coated on the surrounding of described special-shaped metallic conductor, and described self-adhesion enamelled coating is coated on the outside surrounding of described insulation enamelled coating;
Between described two row enameled sheet wires, clamp middle liner paper;
Described external insulation layer is any in insulating paper or grid bundling belt.
Compare with existing transposed conductor, the beneficial effects of the utility model are: the metallic conductor of its enameled sheet wire is the special-shaped metallic conductor that wide center of a side has Baltimore groove, thereby increase wire table area and area of dissipation, improved cooling effect and ampacity; And the Baltimore groove of wide of two upper and lower adjacent enameled sheet wires of every row enameled sheet wire just can form rectangle oil duct to arranging, can further improve cooling effect; In addition, the rectangle oil duct of formation can make the reserved oil duct gap of coiling transformer suitably reduce, thereby reduces winding volume, reduction transformer manufacturing cost.
