Detection module is detected line fault by detecting line status change, and detection module is filled equipped with current detecting
Put, when line fault, the electric current in circuit breaks down, and detection module detects curent change by current sensing means,
Realize the detection to line fault.
Compared with prior art, the present invention routeing online when curent change occurs in short trouble, detection module is according to line
The change of road electric current detects that the laggard action of circuit failure is made, and counting module records detection module action frequency.
State Transferring module is changed according to the counts control signal module status of counting module, remind staff note that
Improve the identification to line fault and location efficiency.
Brief description of the drawings
Fig. 1 is module connection relationship diagram of the present invention.
Embodiment
Attached drawing is only for illustration, it is impossible to is interpreted as limitation of the present invention；It is attached in order to more preferably illustrate the present embodiment
Scheme some components to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by attached drawing.Being given for example only property of position relationship described in attached drawing
Explanation, it is impossible to be interpreted as limitation of the present invention.
Embodiment 1：
As shown in Figure 1, the present invention provides a kind of line fault point detection device, failure point detection device is equipped with detection circuit mutation
The detection module 2 of electric current, detection module 2 by equipped with current sensing means detection line route road in electric current change, judge
Whether circuit breaks down.
As shown in Figure 1, failure point detection device acts once when detection module 2 detects that line current changes,
Detection module 2 is connected with counting module 4, and counting module 4 records 2 action frequency of detection module.Signaling module 5 is equipped with the
One signaling module 51 and secondary signal module 52, State Transferring module 1 is according to 4 counts control signal module 5 of counting module
Different identification signals is sent, was both changed between the first signaling module 51 and secondary signal module 52.
Detection device is connected with communication module, and the identification signal that signaling module 5 is sent is sent to main website by communication module,
The staff of main website confirms failure point detection device action frequency by different identification signals.
Detection device is equipped with communication module, after there is mutation current during detection device detects circuit, trouble point detection
Device is communicated by communication module and main website, and the situation for occurring mutation current in circuit is informed main website.
The specific implementation process of the present invention：2 connection status modular converter 1 of detection module, State Transferring module 1 connect
Timing module 3 and counting module 4.Detection module 2 is acted when detecting that line current changes.Detection module 2 is dynamic
After work, counting module 4 counts 2 action frequency of detection module, and timing module 3 is carried out at the same time timing T1, T1 0.1s-
2s.After the completion of timing, the first signaling module 51 that 1 control signal module 5 of State Transferring module is equipped with carries out slow flash, at this time, letter
Number 5 slow flash of module, detection module 2 are prepared fault condition next time.
When occurring second of curent change in circuit, due to the distributed generation resource in existing line and circuit off-the-line, divide
Cloth power supply no longer provides electric current to circuit transmission failure electric current, only substation after short trouble occurs in circuit to circuit.
Substation conveys electric current, the detection module 2 between trouble point and substation to circuit again after first time failure
After detecting curent change again, the action frequency of 4 bulk registration detection module 2 of counting module, 1 basis of State Transferring module
The secondary signal module 52 that counting module 4 is recorded in number control signal module 5 carries out quick flashing.
Detection device between trouble point and distributed generation resource does not detect curent change, first in signaling module 5
Signaling module 51 keeps slow flash.
Interval division is carried out by the slow flash and quick flashing that are shown to signaling module 5, trouble point is positioned.
After occurring second of curent change in circuit, the control timing module 3 of State Transferring module 1 carries out timing T2, T2 and is
2-5h, within the T2 times, searches trouble point for staff and provides time enough.
After troubleshooting, circuit normally send a little, detection module 2 does not detect mutation current, timing module 3
For circuit without mutation current, T3 3s-10s, confirm that line fault excludes completely after the timing T3 times.
After the T3 times, State Transferring module is transformed into detection module, counting module, signaling module, timing module initially
State.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
