基　　金：专变终端控制扩展模块研制(524636230005)。

摘　　要：我国目前使用的部分电力架构受限于专变终端带负荷能力的不足,无法满足电力使用需求。为此,开发研制了一款专变控制扩展模块。该模块可为专变终端扩展4路控制通道,实现遥控分合闸、控制回路断线检测、遥信状态量采集、程序升级、事件记录以及上报功能。通过硬件、软件设计及测试,验证所设计的扩展模块具备上述功能。The current power grid structure is limited by the insufficient payload capacity of data acquire terminal of special transformer,which cannot meet the needs of power usage.Therefore,this paper developes an expansion module.This module can extend 4 control channels for the data acquire terminal of special transformer,achieving remote opening and closing,control circuit disconnection detection,remote signal status data collection,program upgrade,event recording and reporting functions.This paper verifies that the designed expansion module has the above functions through hardware and software design and testing.
