Abstract

Improvements in magnetic circuits for three-phase electrical transformers, characterized in that they comprise the arrangement of three vertical legs with lower and upper yokes that close the magnetic circuit where each of the vertical legs are located in the vertices of a triangle in a delta configuration and it constitutes with the unión of three frames each formed of rolled strip in a continuous manner, each of these frames being joined on each of two of the opposite sides to one side of a different one of the other two frames and because the joint respective of two sides of adjacent frames is carried out in radial planes spaced approximately 120º apart from each other.
