Summary:The invention discloses a phase-shifting filter transformer, which comprises a transformer mounting rack (1), a core (2) and windings (3), wherein the core (2) is arranged on the transformer mounting rack (1); the windings (3) are wound at the periphery of the core (2); and the phase-shifting filter transformer is characterized in that the windings (3) are formed by winding platy materials, and the windings (3) are made of circular copper bars. The windings wound by the circular copper bars are arranged on the outer side of the core, when the manufactured phase-shifting filter transformer is connected in series to a main loop and supplies power, the aims of purifying the power supply and filtering surge, transient current and higher harmonics can be fulfilled, the three-phase imbalance is effectively improved, and the power factor is improved; and meanwhile, when the phase-shifting filter transformer is used in an inductive load, the influence of the load due to eddy current and higher harmonic components can
