Abstract

The invention discloses an oval transformer coil used in a transformer. A low-voltage coil (1) and a high-voltage coil (2) of the oval transformer coil are in oval shapes, the low-voltage coil (1) is fixed at the outer end of a winding tire die (8), the high-voltage coil (2) sleeves the low-voltage coil (1) in a winding way at interval by coating curtains (5), end insulators (3) are arranged at the two ends of the low-voltage coil (1) and the high-voltage coil (2), and an interlayer insulator (4) is arranged between layers of a wire (6) of the high-voltage coil (2). The coil is designed to be an oval shape, thus, the abrupt short-circuit resistant capability of the transformer is effectively improved, the usage amount of the wire is reduced, the usage amounts of an iron core, transformer oil and a copper bar are reduced, the filling rate of a silicon steel sheet is improved, and meanwhile, the basic loss during running of the transformer is reduced; and moreover, the transformer is more compact in structure, the labor intensity of a final assembly worker is reduced, and the quality and the working efficiency of the transformer are improved.

Description

A kind of elliptical deformation transformer coil

Technical field: the present invention relates to a kind of elliptical deformation transformer coil that transformator uses.

Background technology: at present, mostly is circular, rectangle in the coil winding mold profile that transformer industry is general Or Long Circle three kinds, the usage amount that generally there is wire, iron core, copper bar and transformer oil is big, stalloy Filling rate is high, so that the manufacturing cost of transformator adds 3-4%, increases the basic of Transformer Loss, adds the labor intensity of general assembly workman simultaneously.And cause electrical strength and mechanical strength relatively low, fall The low anti-sudden short circuit ability of transformator, have impact on quality and the work efficiency of transformator.

Summary of the invention: the present invention overcomes and avoid rectangle and the shortcoming and defect of Long Circle coil, it is provided that A kind of structure making transformator is compacter, and manufacturing cost is greatly reduced, and the one improving transformator effect is ellipse Circular transformer coil.

The technical solution adopted in the present invention is: its low-voltage coil 1 and high-tension coil 2 ovalize, low pressure Coil 1 is fixed on coiling loose tool 8 outer end, and high-tension coil 2 is wound on low-voltage coil 1 with being coated with bar curtain 5 spacer sleeve Outside, end insulation 3 is arranged on low-voltage coil 1 and high-tension coil 2 two ends, and layer insulation 4 is arranged on high pressure Wire 6 interlayer of coil 2.

The invention has the beneficial effects as follows: owing to coil design ovalisation, being effectively improved transformator Anti-sudden short circuit ability, reduces wire than circular and other shapes coils the most to a certain extent Usage amount；Shorten the phase spacing of iron core, decrease the usage amount of iron core；Shorten the distance of magnetic circuit, Improve the filling rate of stalloy；Reduce the volume of fuel tank, decrease the usage amount of transformer oil；Shorten The lead-in wire distance of transformator, decreases the usage amount of copper bar.So that the structure of transformator is compacter, Manufacturing cost reduces 3-4%, reduces basic loss and the work of general assembly workman of Transformer simultaneously Intensity, improves quality and the work efficiency of transformator.

Detailed description of the invention: as shown in Figure 1, Figure 2, Figure 3 shows, its low-voltage coil 1 and high-tension coil 2 are in ellipse Circle, low-voltage coil 1 is fixed on coiling loose tool 8 outer end, and high-tension coil 2 is wound on being coated with bar curtain 5 spacer sleeve Low-voltage coil 1 is outside, and end insulation 3 is arranged on low-voltage coil 1 and high-tension coil 2 two ends, layer insulation 4 It is arranged on wire 6 interlayer of high-tension coil 2.

As shown in Figure 1, Figure 2, Figure 3 shows, between described low-voltage coil 1 and high-tension coil 2 and high-tension coil 2 are internally provided with longitudinal oil duct 7.

As shown in Figure 1, Figure 2, Figure 3 shows, described low-voltage coil 1 is double-layer circular cartridge type or the most spiral, high Line ball circle 2 is multi-layer cylindrical.

As shown in Figure 1, Figure 2, Figure 3 shows, its A, B, C and X, Y, Z are low-voltage coil 1 and high-tension coil The terminal of 2.
