In the design of induction filtering distribution transformer, the induction filtering technology is applied to the distribution transformer with Ddy connection group. By establishing the circuit mathematical model,the relationship between the harmonic current generated by the valve side and grid side current is deduced, and the filtering characteristics of induction filter distribution transformer are revealed. ANSYS/Maxwell software is used to establish a 3D model of the new transformer. On the model, the short-circuit impedance between the windings of the transformer is verified to meet the technical requirements by comparing the simulation energy method with the engineering magnetic circuit method. The filter branch is added through magnetic circuit coupling to monitor the grid side current of the transformer, and it is verified that it can effectively filter the harmonic pollution of the power grid. Finally, the correctness and effectiveness of the designed transformer are verified by experiments,which further stimulates students’ learning interest and enthusiasm for innovation.
