| 5-way remote control: flexible configuration of opening, closing, fault signals, etc. | ||
| remote control | On/off ≥ 105, pulse width 1~65535ms can be set | |
data transmission |
communication interface | 3 serial ports RS232, 3 serial ports RS485, 2 RJ45, 1 debugging serial port |
| Communication protocol | IEC60870-5-101,IEC60870-5-104, Support parameter configuration function | |
| Communication cascade | Relay protection, measuring instruments, dehumidification module, battery detection module | |
| When the main station communication is abnormal, the distribution terminal saves the TCOS (COS with time stamps) information that has not been uploaded, and promptly transmits it to the main station when communication is restored; When establishing a new link in the distribution terminal, historical TCOS information is not transmitted | ||
| Capable of single point, dual point, and merged point remote signal processing, supporting remote signal displacement priority transmission | ||
| Telemetry dead zones can be configured for each telemetry point | ||
| Fault identification, over limit alarm transmission | ||
| Support multiple master stations, receiving remote control commands from only one master station at a time | ||
Historical data storage |
Circular storage of 1024 TCOS event records, with file transfer capability for uploading | |
| Circular storage of 31 days of fixed-point records, with file transfer capability for uploading. 96 fixed-point data are generated at equal intervals every day | ||
| Cycle storage of extreme value records for 31 days, which can be uploaded via file transfer. One extreme value record is generated per day | ||
| 30 remote control operation records can be stored in a loop and uploaded via file transfer | ||
| Forward and upload the daily frozen electric energy file generated by the line loss module, as well as the power reverse electric energy freezing value file | ||
Fault recording |
64 sets of waveform data are stored in a loop and can be uploaded to the main station via file transfer | |
| The starting conditions for waveform recording include overcurrent fault, line voltage loss, zero sequence voltage, and sudden changes in zero sequence current, which can be set separately or in combination | ||
| The recording content includes waveform data for the first 4 cycles before the occurrence of the fault and the last 8 cycles after the occurrence of the fault. The number of recording points is 128 per cycle, and the recording data includes voltage, current, and switch position; | ||
| The recording file format follows the format defined in the Comtrade 1999 standard, consisting of CFG (configuration file, ASCII text) and DAT (data file, binary format) files | ||
relay protection |
Three stages of overcurrent, overload, zero sequence overcurrent, zero sequence overvoltage, phase overcurrent and zero current start three times of reclosing, current blocking, anti surge misoperation, synchronous closing, automatic disconnection, voltage exceeding limit, current exceeding limit, PT voltage detection | |
| On site voltage and time feeder automation, on-site voltage and current time feeder automation, based on IEC61850+GOOSE network distributed intelligent feeder automation | ||
| information safety | Integrated security chips require permission authentication to perform maintenance operations on the device. (Optional) | |
Maintain functionality |
Three remote hardware channel configuration, three remote communication point table configuration | |
| Local and remote fixed value modification, local and remote retrieval and configuration of terminal operating parameters | ||
| Remote signaling, telemetry status viewing, remote control output | ||
| Remote download of programs and updates | ||
| The log includes operation records, error records, remote signaling records, SOE records, GPRS records, distinguishing between the main station and local remote control records, and storing 1000 records of each type | ||
| Monitoring and analysis of IEC101 and IEC104 communication protocols | ||
| Capable of self diagnosis and self recovery, capable of self diagnosing various functional boards, important chips, etc., sending alarm messages in case of abnormalities, and automatically resetting in case of software abnormalities | ||
| DC voltage | Route 1, Level 0.2 | |
| At the right time | Support Beidou and GPS time synchronization, SNTP network time synchronization, protocol time synchronization | |
