三相变压器联结组判别新规律及其应用

New Laws of Determining the Transformer Bank Connection Set and its Application

列出了一套三相变压器联结组的判别规律。基于三相变压器的常规钟点表示法来确定三相变压器联接组别有三个因素,即首末端标记、联结相序、联结形状。提出了判别三相变器联接组的一种新方法,使解题变得更方便准确,并用例题来说明了这种新方法的实用性。

Presents a series of rules determining three-phase transformer linked groups. Based on the three-phase transformer connected group the conventional method to determine the three-phase transformer linked group is related with three factors, named： the terminal marks, connection phase sequence, connection shape. Proposes a new method to differ the three-phase transformer linked group. Finally there is an example to show the application of the new method.
