Abstract
The invention provides a special-shaped transposed conductor, which can solve the problem that the heat dissipation performance is poor when the existing transposed conductor is used for large-capacity transformer windings and medium-voltage and low-voltage windings. The special-shaped transposed conductor comprises a plurality of enameled flat wires. Each enameled flat wire comprises a rectangular metal conductor. The rectangular metal conductor is coated with an insulating paint layer. The enameled flat wires are combined to form two rows of enameled flat wires with wide surfaces which are in contact with each other, and the upper surfaces and the lower surfaces of the two rows of enameled flat wires are transposed in the same direction along narrow surfaces. After the two rows of enameled flat wires are transposed, the external parts of the two rows of enameled flat wires are covered by an outer insulating layer. The special-shaped transposed conductor is characterized in that the rectangular metal conductor of each enameled flat wire is a special-shaped metal conductor with a groove which is arranged in the center of the wide surface on one side, and the periphery of the external part of the special metal conductor is coated with the insulating paint layer.
Description
Technical field
The production and processing field that the present invention relates to transposed conductor, is specially special-shaped transposed conductor.
Background technology
Transposed conductor is that enamel-cover copper (aluminium) lenticular wire with certain radical is combined into two row that wide face is in contact with one another, on request on two row enameled sheet wires and below along leptoprosopy, do the same transposition turning to, and make continuous wrapped winding wire with electrician's insulating paper, grid bundling belt.Current transposed conductor is comprised 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, according to standard-required, also between two row enameled sheet wires, clamping middle liner paper 7, 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 when 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 during coiling transformer, winding volume has also been strengthened in reserved oil duct gap, increases manufacturing cost; In addition, when 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 invention provides 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 insulation enamelled coating, 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 along leptoprosopy, do the same transposition that turns to and process, 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 insulation enamelled coating.
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 over against layout;
Described insulation enamelled coating 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, clamped middle liner paper;
Described external insulation layer is any in insulating paper or grid bundling belt.
Compare with existing transposed conductor, beneficial effect of the present invention is: the metallic conductor of its enameled sheet wire is the special-shaped metallic conductor that wide center of a side has Baltimore groove, thereby increased 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 can form rectangle oil duct over against 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.
