Detailed Product Description
Wireless Receive: Receive Fault Point Information From Panel Indicator Through Wireless GSM Or GPRS Transmission: Send Status Information, Fault Information To Master Station By GSM Or GPRS
Main Supply: Powered By Two Roads Of Powered CT, Back Up Used Each Other Characteristic: Battery Can Exchange

power distribution online location and detection system with wireless communication fault indicator easily

 

Data Transmission Unit function is to receive wireless signal from panel indicator then to demodulate and decode,then send the signal to central station by GSM or GPRS.

Wireless Communication Overhead Fault Indicators Two Roads CT Powered Back Up Power SupplyWireless Communication Overhead Fault Indicators Two Roads CT Powered Back Up Power Supply

Main characteristics:

1) Wireless receive:

receive fault point information from panel indicator through wireless

2) GSM OR GPRS send:

send status and fault information to master station,requires confirm detailed requirement before order.

3) Main supply:

powered by two roads of powered CT, back up used each other, if primary line current is not less than 10A, back-up power will not be consumed; or PT powered.

4) Back-up power supply:

equipped with free-maintenance 5AH lithium battery. Under condition of no power for main power source, it can keep device working 5-8 years and fault information not lost and no need to complement energy.

Function:

1. wireless receive: receive fault point signal from panel indicator by wireless

2. GSM or GPRS transmission: send status information, fault information to master station by GSM or GPRS.

3. Power supply way:PT supply or two road of CT supply, if primary current is above 10A,it can work normally.

4. communication protocol:IEC870-5-101 or IEC870-5-104

5. Remotely upgrade:device can easily be upgraded remotely

TYHD-2 panel type fault indicator(be called indicator for short below) is mainly used for switch gears for locally indicate short circuit fault and earth fault and also provide wireless signal output .

The TYHD-2 cable indicator is suitable for the cable 35kV system (including bellow 35kV system).It can only judge short-circuit, without locally indicating function. When short-circuit happened in cable,It can help line finder find the fault quickly .shorten power-off duration,improve the reliability of power supply.

TYHD-2 cable earthed fault indicator is applied to cable system below 35KV, with function of zero-sequence earthed fault detection and fault signal remote transmission function. the panel indicator displays and remotely transmitted the detected fault signal from earthed fault indicator transmitted by optical fiber,when earth fault happened in cable. It can help line finder find the fault location quickly .shorten power-off time,improve the reliability of power supply.
