Transformer with rectangular section iron core

Abstract

The invention discloses a transformer with a rectangular section iron core. The transformer comprises the iron core (1) and coils; the coils are provided with two or more of windings; the winding connected with the power supply is a primary winding while the rest of the windings are secondary windings; the iron core (1) is formed by laminating a plurality of silicon steel sheets (2) of the same width; and the section of the iron core (1) is rectangular. According to the transformer, the iron core with the rectangular section is formed by the same-level silicon steel sheets of the same size; the silicon steel sheets are the same in the level of the width, so that the feeding and discharging time in cutting the silicon steel sheets is saved, the waste of pre-material is reduced, and the laminating process is simplified, wherein the area of the rectangular section of the iron core is the same as the area of a long circular or circular section of the iron core.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer with a rectangular cross-section iron core, belonging to the technical field of transformers. Background technique [0002] The structure of the iron core in the traditional transformer is as follows: figure 1 and figure 2 As shown in the figure, it can be seen that the iron core is made of silicon steel sheets with different widths in multiple stages to form an approximate circular or oblong section. When the silicon steel sheets are cut, the multi-stage sheet widths are fed and unloaded on the cutting line. It is labor-intensive and time-consuming, and an extra part of material will be cut during each level of cutting, resulting in greater waste. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a transformer with a rectangular cross-section iron core, which can save time for loading and unloading during...
