Technical Field

[0001] This utility model relates to the field of power distribution equipment, specifically to a power distribution automation intelligent measurement and control terminal device. Background Technology

[0002] Distribution terminals are a general term for various remote monitoring and control units installed in medium-voltage distribution networks. They are used to complete remote measurement, remote signaling, and remote control functions such as collecting distribution network operating parameters, monitoring equipment operating status, and executing dispatching instructions. According to the major application categories, they can be divided into substation terminals (DTU), feeder terminals (FTU), and fault indicators. Distribution terminals are mainly used in: switching stations, ring main units, distribution substations, pole-mounted switches, distribution transformers, and distribution lines.
