Связь между параметрами электромагнитных, принципиальных схем и схем замещения двухобмоточных трансформаторов

Abstract

Equations of relation between all parameters of electromagnetic and schematic circuits (two magnetically coupled circuits) and galvanically coupled Т- and pi-equivalent circuits without magnetic coupling are deduced for double-winding transformers. This approach can also be applied to double-winding reactors. The obtained formulas facilitate designing of both converting equipment by means of electromagnetic and electrical schematics of transformers and electromagnetic elements through application of transformers' equivalent circuits because they unite different approaches for transformer calculation. Rules of sign arrangement in the equations of transformers are systematized.
