摘　　要：概括介绍了三相三柱式三相交四相变压器和四相四柱式三相变四相变压器。在分析两种不同铁心结构三相变四相变压器原理的基础上,通过讨论电流变换关系,分别给出两种变压器的差动保护接线方案。所使用的电流变换关系具有一般性。Three-limb three phase to four phase transformers and four-limb three phase to four phase transformers in general terms are Introduced. On the basis of analyzing two types of three phase to four phase transformers different in core structure, two kinds of differential protection connection scheme are put forward according to discussing the relation of current transformation. The relation of current transformation allows a wide latitude of generality in applications.
