Safety criterion
Welcome to use remote transmission unit manufactured by us. Each remote terminal uint has already experienced the complete assembly, test and inspection, also the careful check and adjustment before delivery, which has been in good condition when transport.
Device description
Remote terminal uint is the data acquisition and communications forwarding device for power distribution network load monitoring, fault detection and positioning system, which can be set as the practical distribution terminal device of two remote (remote signaling, telemetry) functions in the distribution automation system via terminal parameter configuration, which can also be set as the traditional distribution terminal device of remote fault positioning system.
Remote terminal uint is to process and analyze the information from overhead indicator sent via wireless and then send the circuit load current and fault information to the main distribution network station via GSM short messages or GPRS communication.
Working principle
Remote terminal uint is to receive the circuit fault information and circuit load operation information from overhead indicator installed in the circuit via wireless for analysis and compiling and then sends the information to main distribution network station via GPRS/GSM communications, to realize the online monitoring, fault detection and positioning functions of distribution network.
GSM or GPRS forwarding
GSM (short messages) and GPRS (data) are mutually the standby mode, which are used to send the substation condition, circuit load current, indicator status and fault information to main distribution network station, to ensure the reliable transmitting of distribution network fault information.
Remote upgrade
The equipment program can be upgraded conveniently through master remote maintenance station.
Work mode setting
The terminal can be in the two-remote or one-remote working mode by setting the intrinsic parameters of remote terminal uint.
Two-remote working mode: the terminal is online in real time, and the circuit load current and circuit status can be uploaded.
One-remote working mode: the terminal is online regularly; when the circuit breaks down, the terminal opens GPRS module power supply and sends the fault information to main distribution network station.
