Abstract

The invention discloses a transformer set. The transformer set includes three dual-column single-phase transformers, wherein the dual-column single-phase transformers respectively include a first corecolumn of a rectangular frame core, a second core column, a high voltage coil and a low voltage coil disposed on the first core column, and a high voltage coil and a low voltage coil disposed on thesecond core column. The transformer set is advantaged in that each core column includes only one low voltage coil, the magnetic coupling relationship along the low voltage coils is avoided, so leakageof a magnetic field due to unbalanced loads is avoided, eddy current loss is further avoided, and a problem of transformer fault caused by the unbalanced loads is avoided, moreover, compared with a three-phase axial dual-split transformer in the prior art, the three-phase dual-column dual-split transformer set is utilized, and the transformer set is safer and more reliable.
