Embodiment 1

[0016] Embodiment 1: A long waist-shaped energy-saving transformer is installed in a power distribution cabinet. The transformer includes an iron core 1 , a winding 2 surrounding the iron core 1 , and a support 3 supporting the iron core 1 and the winding 2 .

[0017] The cross section of the winding 2 in the horizontal direction is a rectangle surrounding the iron core 1 , the rectangle includes four sides, and two adjacent sides are connected by a circular arc so that the cross section of the winding 2 has a long waist shape.

[0018] Further, the arc ends of at least one set of opposite ends of the elongated waist are directly connected. For example attached figure 1 As shown, the circular arcs at the two ends of a set of shorter opposite sides of the long waist are directly connected, and the diameter of the two arcs is equal to the distance between the other set of longer opposite sides of the long waist, so This makes the winding 2 appear in such a long waist shape: it...

Abstract

The invention relates to a long-kidney-shaped energy-saving transformer arranged in a power distribution cabinet. The long-kidney-shaped energy-saving transformer comprises an iron core and a winding surrounding the iron core, wherein a section of the winding is a rectangle surrounding the iron core, the rectangle comprises four edges, and two adjacent edges are connected through a section of circular arc, so that the section of the winding is long-kidney-shaped. According to the long-kidney-shaped energy-saving transformer, the section of the winding of the transformer is changed to be long-kidney-shaped, so that compared with original windings with rectangular sections or circular sections, the circumference of the winding is smaller, accordingly, the raw materials for manufacturing can be reduced under the condition that original magnetic flux is not changed, and the size of the transformer is reduced.

Description

technical field [0001] The present invention relates to a transformer, in particular to the structure of the winding in the transformer. Background technique [0002] Transformers used in power distribution cabinets are mainly composed of brackets, iron cores and windings. In the prior art, the iron core usually has a rectangular or circular cross-section, and the winding has a rectangular or circular cross-section suitable for the iron core and is arranged around the outside of the iron core. The winding of this structure makes the overall volume of the transformer larger, and more raw materials are used to manufacture it. Contents of the invention [0003] The object of the present invention is to provide a long-waisted energy-saving transformer that saves manufacturing materials and has a small volume. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A long waist-shaped energy-saving transformer, which ...
