AI Technical Summary
When designing △-△ phase shift transformers with 12-fold winding output, it is difficult to adapt to high-voltage systems of different voltage levels, resulting in poor product consistency, inconsistent harmonic effect, and long project development cycle.
A △-△ phase shift transformer with a 12-fold winding output is designed. The low-voltage end winding includes at least one group winding. Each group winding includes 12 three-phase low-voltage phase shift windings using epitaxial △ connection method. Each low-voltage phase shift winding consists of the basic coil D1 and the epitaxial coil Y1. The number of turns configurations are arranged according to the specific table data to optimize the harmonic elimination effect.
It realizes relatively optimized harmonic effect and balanced output waveform, adapts to high-voltage systems with different voltage levels, and improves product consistency and development efficiency.
