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
