摘要
Abstract
Wiring principles and structure characteristics of three kinds of three-phase to four-phase power transformers were compared. Their advantages and disadvantages were summarised respectively. Simulation models of three kinds of transformers were established and the simulation experiments under different load conditions were performed. The performance comparison results of different transformers indicate that three-phase to four-phase transformer with impedance match balancing, whose wiring impedance satisfies the constraint relations in order to realize electromagnetisin balance between windings, has high material utilization because of no zigzag connection. It has distinct advantages in the transform process of three-phase to four-phase comparing to other structures.关键词
