Evolution of structures and preconditions for transformers and reactors improvement via electromagnetic system circuits transformation (elecrodynamic stability and systems with combined butt magnetic cores)
Results and prospects of further evolution, features and ways of electrodynamic stability control for electromagnetic systems of transformers and reactors are analyzed. Examples of structural transformation of a spatial axial system with a belt-plate butt magnetic circuit on the basis of multiplane forming surfaces of rods and coil windows are presented.
