      ​ the overhead "three remote" terminals, also known as feeder terminals, are distribution terminals installed at overhead line towers and other locations in the distribution network. they cooperate with switches to monitor the operation of the real-time distribution system, complete functions such as data collection, line protection, switch control, and communication with the main station, providing technical support for real-time monitoring and scheduling of the distribution network. it can cooperate with the main station to achieve centralized fa function, and can cooperate with upper and lower level terminals to achieve distributed fa function.

      performance characteristics

      three remote functions protection function intelligent distributed logic function remote/local operation power function communication function status indication data processing function fault monitoring

      product features

      three remote functions: telemetry, remote signaling, and remote control;

      protection functions: three-phase three-section overcurrent protection function, zero sequence protection function, reclosing and blocking reclosing function;

      intelligent distributed logic function: achieving local fault clearing, automatic fault isolation, automatic transfer of power supply, and automatic restoration of power supply in non faulty sections; logic manual, automatic reset and other functions;

      remote/local operation: the remote/local closing and opening operations are mutually locked, and the control outlet is controlled by the soft and hard pressing plates for on/off;

      power function: dual power switching, automatic seamless switching to backup power supply in case of ac power loss, and automatic management (battery activation, alarm, protection) function for backup power supply;

      communication function: multiple network and serial ports, supporting multiple communication protocols;

      status indication: there are obvious local status indication signals for operation, communication, line faults, etc;

      data processing function: arbitrary configuration and combination of data sent by the main station; distribution transformer load rate, three-phase imbalance, remote sensing exceeding limit, extreme value, qualification rate statistics, etc;

      fault monitoring: receiving and forwarding fault indicator signals; coordinate with variable load cabinet to determine single-phase grounding fault
