Abstract
The utility model relates to a combined wire for a winding coil. The wide faces of the paper parcel copper flat wires of definite number make overlapping contact with each other, and multilayer insulation papers are adopted to be continuously and tightly wound on the paper parcel copper flat wires; so the utility model is formed. Compared with the coil which is formed by the single paper parcel wire, if the coil adopts the combined wires and is used, the integration performance and the mechanical strength of the coil can be obviously improved, the transformer volume can be reduced, and the heat dispersion can be enhanced.
Description
The utility model relates to a kind of transformer winding coil.
For making transformer in transformer oil, have excellent mechanical intensity and proof voltage, oil resistant water characteristic with coil.At present, general large and medium-sized Winding in Power Transformer is the circulation influence several paper bag copper strap wires helically coilings in parallel that adopt that overcome winding more, for improving the capacity of transformer, usually the axial line turn-to-turn at winding all has the oil duct that supplies heat transmission, such problem is always arranged in this technical process, (1), owing to contact not closely between the paper bag core root of coiling and the root, oil duct is dwindled in the transformer quality that reduces transformer in service.(2), for guaranteeing the interlayer electrical property of winding, its external insulation intensity of paper covered wire of many parallel connections is all identical usually, but turn-to-turn insulation intensity in fact in parallel is very not high, this has just caused the Transformer Winding volume ratio bigger, the insulation service efficiency is lower.(3), owing to be the coilings in parallel of many paper covered wire, the time that is used for coiling is longer, can not obtain satisfied effect.
The utility model can overcome above-mentioned shortcoming effectively, and a kind of paper insulation paper bag composite conductor is provided.
The technical solution of the utility model is achieved in that forming cross section with wide overlapped contact of some paper bag copper strap wires is the wire harness of rectangle, and it is wrapped to adopt electric insulation paper to make multilayer outside wire harness, makes it have a public outsourcing insulation.
Structure of the present utility model is wrapped because only relate to the combination of many paper bag copper strap wires, so make easily, adopt the advantage of composite conductor to be that the core that some flat wire with paper wrappeds are combined has a public insulating barrier outward, make its coil amass the overall performance and the mechanical strength that more can improve coil under the identical situation with cross-sectional area of conductor in dielectric strength than single flat wire with paper wrapped coiling, shorten the coiling time, winding volume is also reduced, and reduces the transformer manufacturing cost.Solved the loose problem between the line line, oil duct strengthens the heat dispersion that has strengthened coil.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof: accompanying drawing 1, be used for the composite conductor structural representation of winding coil.Accompanying drawing 2, be used for the composite conductor cross-sectional view of winding coil.Among the figure 1, core 2, composite conductor 3, outsourcing insulating paper layer
As shown in the figure: at first wide coincidence of 3 paper bag copper strap wire cores (1) put, add insulating paper (3) then and do overlapping closely wrapped.Just make paper insulation paper bag composite conductor (2).Can directly apply in the power transformer.
Claims (1)
1, a kind ofly forms a kind of rectangular cross section, be used for the composite conductor (2) of power transformer, wide overlapped contact of these single paper covered wire (1) by some flat paper covered wire.It is characterized in that the public insulating barrier of a paper insulation (3) is arranged outside the wire harness of complete overlapping contact.
