Research on Numerical Calculation of Short-circuit Impedance and Current Distribution of Amorphous Phase-shifting Transformer

Use magnet software to calculate the leakage magnetic field of an amorphous phase-shifting rectifier transformer with three-dimensional finite element, and compare with the test value to verify its simulation accuracy. The results of the two-dimensional and three-dimensional simulation short-circuit impedance calculations are compared and analyzed, and the short-circuit impedance, leakage magnetic field distribution, and current distribution of the transformer under different working conditions are calculated and analyzed.
