This kind of device is applied to the overhead power distribution
network automatic system from 6KV to 35KV,is used to improve the
safe and reliable operating performance through centralized
monitoring the current, temperature and fault condition on the
power distribution circuit.
system Constructure:
Main features:
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.
Functions:
1)Wireless receiving: the fault point information and load current
information sent by indicator are received via short-range wireless
network mode.
2)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.
3)Solar power supply: the solar power supply mode is applied, and
the maintenance-free 8AH lead-acid battery or 12AH lithium iron
phosphate battery is provided, with the working temperature range
of both batteries of -35℃~75 ℃ and -20℃～75℃ separately.
4)Optional communication protocol: IEC870－5－101 protocol or 104 can
be selected for the connection with the third party equipment to
upload the fault and shift information.
5)Remote upgrade: the equipment program can be upgraded
conveniently through master remote maintenance station.
6)Convenient maintenance: the parameter setting and equipment
maintenance can be performed conveniently via wireless setting
terminal.
7)Event recording: the device can record the maximum 500 pieces of
SOE events, providing the rich data support for system fault
analysis.
