Design and magnetic field analysis of linear phase-shifting transformer with hairpin filling structure
摘要
Abstract
Based on the original linear phase-shifting transformer,a linear phase-shifting transformer with a hairpin filling structure was designed with reference to the theory of linear motor,which effectively solved the problems of complicated winding method,large size and modular series-parallel connection.At the same time,it improved the problems of reduced primary side excitation current density and air gap magnetic field distortion caused by the semi filled slot at the connection during modular connection.Working principle of the linear phase-shifting transformer system was briefly introduced;the design method of linear phase-shifting transformer with half-filled slot structure was proposed with reference to the design method of linear motor and rotary motor;the hairpin structure was adopted to eliminate a series of problems caused by the half-filled slot structure at the connection;finally,the finite element simulation was used to verify the comparison.Results show that the designed linear phase-shifting transformer with a hairpin structure has a good output waveform and a small distortion of the air gap magnetic field.关键词
