Embodiment Construction

[0016] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0017] Such as figure 1 , 2 As shown, an elliptical coil mold for a transformer according to the present invention has a plurality of identical elliptical components, each elliptical component is arranged horizontally, stacked in the vertical direction, and spacers 9 of the same structure are passed between each elliptical component. Support, the major axis and minor axis of each elliptical member are overlapped in the vertical direction, and the periphery is surrounded by stays 6 to form the main body of the mold; the above-mentioned mold main body is installed on the bottom plate 11 as a whole, and a central axis is set at the center of the elliptical member 2.

[0018] Such as image 3 , 4 As shown, the elliptical member is in the form of a plate, that is, an elliptical formwork 8, and the center positions of each elliptical formwork 8 are se...

Abstract

The invention relates to an elliptical coil mold for a transformer, which has a plurality of identical elliptical components, and each elliptical component is arranged horizontally and stacked in the vertical direction, and the elliptical components are supported by pads of the same structure, and each The major axis and minor axis of the elliptical component overlap in the vertical direction respectively, and the periphery is surrounded by stays to form the main body of the mold; the above-mentioned mold main body is installed on the bottom plate as a whole, and a central axis is set at the center of the elliptical component. The specifications of the elliptical coil mold for transformers in the present invention can be adjusted according to needs, not only has strong versatility, but also has simple mold processing and assembly, convenient installation and disassembly, wide practicability, not only reduces manufacturing costs, but also ensures product quality and fills This blank was created for the oval coil die.

Description

technical field [0001] The invention relates to the technical field of transformer manufacturing, in particular to an elliptical coil mold for a transformer. Background technique [0002] The coil is the most important part of the heart of the transformer. The manufacturing quality of the coil is directly related to the reliability of the transformer operation. There are many structures of the coil, and the commonly used ones are round, oblong, square, etc., regardless of the mold manufacturing. Or coil winding has a relatively mature mode in technology. With the continuous advancement of technology in the field of power transmission and transformation in my country, the capacity of transformers and reactors used on transmission lines is constantly increasing. In the design of transformers and reactors, the structure of the coil is also constantly changing. Shaped coil is a new type of coil structure. Oval coils are characterized by different radii of curvature at each loca...
