Abstract

The utility model relates to an open triangle transformer iron core, which particularly consists of three same iron core columns, an upper iron yoke and a lower iron yoke that are in butt joint. Eachiron core column is formed by superposing silicon-steel plates with the same length and the different widths in each group; the cross section of each iron core column takes the stepped shape and is arranged in a circumcircle; and the upper iron yoke and the lower iron yoke are the same triangle frames formed by winding silicon-steel plates with equal width. A transformer made of the iron core hasthe advantages of light weight, less iron loss, low noise, convenient winding and the like.
本实用新型涉及一种开口式三角形变压器铁芯,具体地说它是由3个相同的铁芯柱与上、下铁轭对接所组成,每个铁芯柱是由长度相同,宽度各组不同的硅钢片叠合在一起组成,每个铁芯柱横截面呈阶梯形状并在一个外接圆内,上、下铁轭是用等宽度的硅钢带卷绕而成的相同的三角形状的框。利用该铁芯制作的变压器具有重量轻,铁损小,噪音低,绕线方便等优点。
