摘　　要：三相变压器联接组别(包括其标号)不同,说明一、二次对应线电压相位差不同。目前应用Y、Δ形布局电压相量图虽然可以确定联接组别标号,但是阅识较难,不利于实际应用。论文通过创新设计方案,应用纯Y形布局相量图、同时简化相量字母标识,形成了实用的相量图;结合变压器绕组连接方式,就能有效、直观地判别变压器联接组别。最后应用设计列出了24种变压器接法及其联接组别。The three-phase transformer connection group（including its label） is different, indicating that the phase difference of the first and second corresponding line voltage is different. At present, although Y and Δ-shaped layout voltage phasor diagrams can be used to determine the number of the connected group, it is difficult to read the information, which is not conducive to practical applications. This article through the innovative design program, the application of pure Y-shaped layout phasor diagram, while simplifying the phasor letter logo, forming a practical phasor diagram; combined with the transformer winding connection, can effectively and intuitively determine the transformer connection group. Finally, the application design lists 24 transformer connections and their connection groups.
