Description

Elliptical deformation transformer coil

Technical field: the utility model relates to the elliptical deformation transformer coil that a kind of transformer uses.

Background technology: at present, circle, rectangle or Long Circle three kinds mostly is in the coil winding mold profile that transformer industry is general, the use amount of ubiquity wire, iron core, copper bar and transformer oil is large, the filling rate of silicon steel sheet is high, thus make the manufacturing cost of transformer add 3-4%, increase the basic loss of Transformer, add the labour intensity of general assembly workman simultaneously.And cause electrical strength and mechanical strength lower, reduce the anti-sudden short circuit ability of transformer, have impact on quality and the operating efficiency of transformer.

Utility model content: the utility model overcomes and avoids the shortcoming and defect of rectangle and Long Circle coil, provide a kind of structure of transformer that makes compacter, manufacturing cost significantly reduces, and improves the elliptical deformation transformer coil of transformer effect.

The technical scheme that the utility model adopts is: its low-voltage coil 1 and high-tension coil 2 ovalize, low-voltage coil 1 is fixed on coiling loose tool 8 outer end, high-tension coil 2 is outside around low-voltage coil 1 with being coated with bar curtain 5 spacer sleeve, end insulation 3 is arranged on low-voltage coil 1 and high-tension coil 2 two ends, and layer insulation 4 is arranged on wire 6 interlayer of high-tension coil 2.

The beneficial effects of the utility model are: due to coil design ovalisation, effectively improve the anti-sudden short circuit ability of transformer, reduce again the use amount of wire to a certain extent than coil that is circular and other shapes simultaneously; Shorten phase spacing unshakable in one's determination, decrease use amount unshakable in one's determination; Shorten the distance of magnetic circuit, improve the filling rate of silicon steel sheet; Reduce the volume of fuel tank, decrease the use amount of transformer oil; The lead pitch shortening transformer from, decrease the use amount of copper bar.Thus making the structure of transformer compacter, manufacturing cost reduces 3-4%, reduces the basic loss of Transformer and the labour intensity of general assembly workman simultaneously, improves quality and the operating efficiency of transformer.
