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
