The device can be customized as clients' different requirement. the whole monitoring system includes indicators and Data transmission unit. one DTU can connect 12 indicators. 1 set indicators is composed of 3 pcs.

Description

This kind of device is applied to the overhead power distribution network automatic system from 6KV to 69KV,is used to improve the safe and reliable operating performance through centralized monitoring the current, temperature and fault condition on the power distribution circuit.The fault indicator is used for indicating of phase-to-phase and phase-to-earth faults by determining short circuit, over-current and power features to detect faults and provide a local light indication. In addition, the indicator also has current measurement and wireless data communication capabilities, by sending the fault signal to FTU,in order to comply the function of the remote communication and the remote monitoring, to help operators to find the point of failure quickly and shorten the outage time and improve reliability.

Principle:

The fault indicator installed on the overhead lines, which clipped on each phase so that to detect current and Voltage signal in this phase using itself clipped line structure. Through the low-power chip, it completes current calculation, short circuit, ground fault detection, and through built-in low-power RF modules achieves short distance wireless communication.

After the indicator is installed, the line current has been measured . When the current meet the characteristics of the fault, the indicator immediately sends the fault current and the fault information to the nearest terminal device by the RF, while triggering a flop and flash indication.

The lineman simple follows the flashing fault indicators all the way to the first non-flashing fault indicator, thereby identify the fault location.

The terminal device receives the fault information can further upload, so master station can get useful information and determine the fault zone according to the sub-station uploaded information.

Shocks and vibrations

 

Power frequency magnetic field test

When continuous sine waveform, 100A / m magnetic interference applied to the indicator, it should work correctly.

b) Grip test

The downward pressure in the direction perpendicular to indicator spring is not less than 8 times the weight of the overall indicator .After fault indicator mounted ACSR, the transverse tension along a direction of aluminum wire is not less than 50N. So that, Indicator can withstand winds without falling from the line.

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.

removal

a)Install the bracket in the hot sticks,and let the hook outward open, and screw detaching sheet nut to let the sheet leaned out of the column.It is best to made the screws on both sides of the detaching sheet leaving 4-5 buckle (wire length).

Data Transmission Unit

 

1. 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.

2. 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.

3. Main features

3.1 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.

3.2 Remote upgrade

The equipment program can be upgraded conveniently through master remote maintenance station.

3.3 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.

4. 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.
