摘　　要：三相变压器连接组别对变压器并联运行、提高输电及配电效能等方面影响明显。本文使用时钟法分析了三种常用三相变压器连接组别并绘制了向量图。在Simulink软件中对三种连接组别进行建模、仿真,主要分析了变压器一次侧相电压、一次侧线电压与二次侧对应线电压三者之间幅值及相位关系,仿真结果与时钟法的向量图结果一致。仿真结果更加直观,能够可以为三相变压器连接在实践应用提供理论依据,促进工程技术人员对变压器连接组别方面的应用。The connection groups of three-phase transformers have obvious effects on the parallel operation of transformers,the improvement of transmission and distribution efficiency,etc.In this paper,the clock method is used to analyze three common three-phase transformer connection groups and the vector diagram is drawn.Three connection groups are modeled and simulated in Simulink software.The amplitude and phase relationships among the primary side phase voltage,primary side line voltage and secondary side corresponding line voltage of the transformer are mainly analyzed.The simulation results are consistent with the vector diagram results of the clock method.The simulation results are more intuitive,which can provide a theoretical basis for the practical application of three-phase transformer connection,and promote the application of engineers and technicians to the connection groups of transformers.
