Expansion Module Based on Data Acquire Terminal of Special Transformer
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.
