Historical data storage |
Loop store 1024 TCOS event records, which can be uploaded via file transfer. | |
| 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 ofthe fault and the last 8 cycles after the occurrence ofthe 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 |
Quick break, overcurrent, overload, zero sequence overcurrent, triple reclosing, current blocking, anti surge misoperation, voltage exceeding limit, current exceeding limit, PT voltage detection | |
| Adaptive local feeder automation, voltage time type local feeder automation, voltage current time type local feeder automation | ||
| Equipped with manual reset, automatic reset, and remote reset functions for fault indication, it can automatically reset according to the set time or the restoration of normal power supply to the line, and can also automatically select the reset method based on the nature of the fault (instantaneous or permanent) | ||
information safety |
Integrated security chip, supporting the parsing function of X.509 standard format SM2 digital certificate, SM1 data encryption and decryption function, SM2 algorithm signature and authentication function, SM2 algorithm public-private key pair generation function, and message authentication code MAC calculation and verification function |
|
| Can monitor the working status of security chips | ||
| Permission authentication is required to perform maintenance operations on the device | ||
| DC voltage | 2 routes, level 0.2 | |
