6-35KV power distribution overhead line transient recorder communicable fault passage indicator

 

TYAI-3 overhead line transient recorder communicable fault passage indicator is used for 6-35KV power distribution overhead line, can monitor line’s running signal like load current, phase electrical field strength,fault current etc. & monitor status signal like main power supply and standby power supply. And also, it can transmit these data and signals to master station and record the fault wave from lines meanwhile.

Fault recorder data is sent to master station in form of Comtrade 1999 standard file format. Data transmission conform to SGCC power distribution automation DLT_634.5101(104)-2002 rules and implementation details, overhead line transient recorder communicable fault passage indicator can be used to monitor line running parameters, monitor every kind of short-circuit, earth fault, and send the monitored information and detected fault data to master station. It can analyze the line status including line fault,line load, power quality by means of power line comprehensive analysis technology based big data, which provides complete and reliable data support for optimizing power distribution network structure.

Principle Instruction:

1)Whatever the power distribution network is Neutral indirectly grounded system or Petersen-coil grounded system, there is a transient process lasting 5-20 milliseconds at the instant of fault happen. In the process of transient process, zero sequence current i0 will generate high frequency transient signal with higher amplitude.

2)Power distribution overhead line smart monitoring ball can capture this high frequency transient current signal and locally detect single-phase-to- earth fault cooperates with zero sequence electrical field signal.

3)In the same way with location of short-circuit, the master station locate Neutral indirectly grounded system fault by single-phase-to-earth fault remote fault signal

4)Neutral indirectly grounded fault location way 2: network detecting location.

5)The transient zero sequence current waveform for fault line is not similar to that in non-fault line

6)The transient zero sequence current waveform of fault current path in fault line is similar

7)The transient zero sequence current waveform of fault current path and non-fault current path in fault line are not similar.

Functions and Characteristics:

1.Gathering unit instruction:

1)Innovative small current self-charging technology, 5A line current can support full-function & real-time on line operation.

2)The current is measured by electrical CT, the accuracy is ±1%/±3A

3)The line electric field to ground is measured by electrical field sensor which is optimal designed to overhead line electrical field distribution , the sensor is not affected by multiple-circuit line on same pole and can recognize the line voltage drop and power outage accurately.

4)High speed of wave record for 4kHz line current and electric field to ground, it can capture the transient waveform signal of the instant the small current grounding fault happen.

5)The wireless and real-time maximum error of three-phase time synchronization is realized to ± 100 μs c. according to the fault transient recording waveform. According to the fault transient recording waveform, The transient zero-sequence current,zero-sequence electrical field signal and small current grounding fault detection &location are captured by three-phase superposition .

2. Assembling unit instruction:

1)Flexible networking & safety data transmission

2)Accurate absolute timing scale is available by GPS high precision timing

3)Three phase synthesis zero-sequence current, electrical field signal and accurate and local detection & location for earth fault

4)communication is stable and reliable

5)Ultra low power consumption

6)High reliable power supply system

7)Remote maintenance and update

8)Unit clock error is not above 1s.

Installation for FPI:

1. Installation steps

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.

2. 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).

b) lift bracket alignment the fault indicator installed in the overhead line and hard pushed up, so that the fault indicator clipped in the bracket, forced to drop down the hot sticks, the indicator can be removed.

Note: FPI have to be installed as the instruction. The user will take responsibility by himself if not operate as the instruction.
