Product Features
Three remote functions: telemetry (including direct flow), 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; Wireless communication: capable of wireless communication through touch laptops;
Wireless communication: capable of wireless communication through touch laptops;
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 detection: achieving on-site fault clearing, automatic fault isolation, automatic transfer of power supply, and automatic restoration of power supply in non fault sections; Logic manual, automatic reset and other functions;
