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. When received, the repeater station shall be carefully checked for damage during transport, and in case of any problem, the carrier shall be reported immediately in written.
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.
Main features
1.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.
2 Remote upgrade
The equipment program can be upgraded conveniently through master remote maintenance station.
3 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.

installation
a) By fitting the bracket installed in the hot sticks, screw detaching sheet nut to let the sheet fully retracted into the interior of the column (ie: try to tighten the sides, leaving enough space so as not to block the indicator when installing).
b)put the indicator into the bracket , and make the spring device to hook with the indicator spring, and rotate the spring device down firmly until after the indicator spring pulled position retractor can hook, then hook the spring with retractor and pull t he spring device out. And use the same method to the other side of the same end of the indicator spring to hook retractors.
c) Aligning the overhead lines pushed up and under the pressure of the overhead lines the indicator springs are divorced from the retractor spring and stucked overhead lines firmly.
