摘　　要：为了实现电子式互感器与保护、测控设备装置之间的数字接口,介绍了电子式互感器数字接口的重要组成部分,即合并单元的功能,根据其特点提出了一种基于FPGA和DSP平台的电子式互感器数字接口实现方案。利用FPGA与DSP相互配合完成合并单元同步,多路数据接收和处理,以及以太网通讯功能,满足了电子式互感器数字接口高速、可靠的要求,有望应用于实际系统中。The realization of the interface between electronic transducer and measurement or protection device is of great significance. The function of merging unit which is the key element of the interface is simply introduced in this paper. Considering the characteristics of the interface, a new realization method of the interface to electronic instrument transformer based on FPGA ＆ DSP is proposed. By using FPGA and DSP together, the merging unit synchronism, the receiving and treatment of multi-channel data, and the function of communicating in Ethernet are finished. The method has met the needs （high speed and reliability） of the electronic transformer and has practical value for application.
