underground power cable locator,
cable fault distance locator
optical fiber communicable fault indicator for underground used for output wireless signal
The TYHD-1cable indicator is suitable for the cable 35kV system (including bellow 35kV system).It can indicate while there is short circuit ,measure electric current,measure temperature(temperature probe attached) and transmit data.It can help line finder find the fault quickly .shorten power-off time,improve the reliability of power supply,be convenient for users to monitor the load current of line on real time.
The TYHD-1cable indicator of short circuit fault.
The principle is clip-on line sensor and intelligent controller . The intelligent controller control as the core with little power consumption ,The clip-on sensor can measure the load current on real time,and transmit the current data by fiber timing. When a circuit has a short circuit fault,The cable short circuit indicator recognize it automatically ,then judge intelligently ,then display locally.At the same time transmit the action signal to the panel type indicator installed locally by fiber,which can display locally on the panel .Of course,It can transmit the data to fiber type monitoring terminal by data remote interface,realizing the remote transmission of fault signal and measured data.
1 Clip the indicator on the line
2 Connect the data remote interface of the indicator to fiber transmitting terminal by short-distance fiber.
3 Connect pulse port of the indicator to panel type indicator by fiber.(the pulse port not needed to connected without panel indicator)
1 .Install and disassemble easily,be suitable for Cable lines with a diameter of less than 40 meters.
2 .The short circuit fault can be found.
3.The line load current can be detected in real time.
4.The faults can be indicated locally by flashing.
5.Epoxy pouring,fully sealed structure,can run outdoors for a long time.
6.Tracking the load current automatically without any setting.
7.Reset automatically,the time can be set before delivery.
8. Inhibiting the closed current automatically.
9.Fiber data communication:
Indicating locally by transmitting the action message from fault indicator to panel indicator(no panel indicator is not available).
Translating remotely by translating load current and action message to cable terminal by fiber.
10.Take the power from the circuit current and the built-in backup lithium battery.
