Abstract
The invention discloses a distributed cable fault detection system, which comprises a plurality of distributed detection units equidistantly arranged on the cable and a GPRS communication module for communication, wherein each distributed detection units is in two-way signal connection with a fault detection platform via the GPRS communication module. According to the distributed cable fault detection system, when the cable works, voltage of each point on the cable is acquired in real time via voltage transformers in the plurality of distributed detection units equidistantly arranged on the cable; through a data comparison module, the real-time voltage of each point is compared with a preset qualified voltage interval, if in the qualified interval range, a green signal lamp is on, a red signal lamp is off, and thus, the actual voltage of the point on the cable does not fail; and if after comparison, voltage of the point or several points fails, a worker can find out fault happening points conveniently in the above method, and subsequent remedial measures can be taken conveniently.
Description
Technical field
The present invention relates to fault detection technique field, be specially a kind of cable distribution fault detection system.
Background technology
The immediate cause of cable fault be insulation reduce and breakdown.Cause a lot of cable fault of factor that insulation reduces
Can be summarized as ground connection, short circuit, broken string three class.
The reason that cable breaks down has external force damage, humidified insulation, chemical attack, long-term running overload, cable to connect
Head fault, environment and temperature and the normal aging of cable body or natural disaster etc..
But, when above-mentioned all kinds of reasons make cable break down, the running voltage of cable all can change, because of work
Low voltage or higher, causes cable to break down.Staff typically uses reality during voltage transformer detection cable work
Border voltage.But, traditional Cable fault examination system, it has not been convenient to the trouble point that detection cable breaks down, thus inconvenient
Take follow-up remedial measure.To this end, it is proposed that a kind of cable distribution fault detection system.
Summary of the invention
It is an object of the invention to provide a kind of cable distribution fault detection system, to solve above-mentioned background technology carries
The problem gone out.
For achieving the above object, the present invention provides following technical scheme: a kind of cable distribution fault detection system, including
The Distributed Detection unit that several are equidistantly positioned on cable, also includes the GPRS communication module for communication, Mei Gefen

Each Distributed Detection unit all include controller, microprocessor, signal lamp, for detect cable each point electricity
The voltage transformer of pressure, for carrying out the comparing module of voltage ratio pair, for the feedback cable defective information of this point voltage
Feedback module.
Described controller is bi-directionally connected with comparing module, the outfan of described controller and the input of signal lamp
End connects.
The described input of comparing module is connected with the outfan of voltage transformer, described comparing module defeated
Go out end to be connected with the input of microprocessor by feedback module, the outfan of described microprocessor and the input of signal lamp
End connects.
Preferably, described signal lamp includes the greensignal light for sending voltage normal signal and for sending
The red eye of voltage fault signal.
Compared with prior art, the invention has the beneficial effects as follows: this cable distribution fault detection system, work at cable
Time, by the voltage transformer in several Distributed Detection unit being equidistantly positioned on cable, to each point on cable
Voltage carries out Real-time Collection, then by comparing module, is carried out in the interval of the real-time voltage of each point with default qualified voltage
Comparison, if in the range of interval of acceptance, then greensignal light lights, and red eye cuts out, and represents the actual electricity of this point of cable
Pressure fault-free；If after comparison, show that this point or this some voltage break down, by the way, facilitate staff to look into
Look for fault generation point, conveniently take follow-up remedial measure.
Accompanying drawing explanation
Fig. 1 is present system principle schematic.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme: a kind of cable distribution fault detection system, including some
The individual Distributed Detection unit being equidistantly positioned on cable, also includes the GPRS communication module for communication, each distributed
Detector unit is all connected with failure monitoring platform two-way signaling by GPRS communication module.
Each Distributed Detection unit all include controller, microprocessor, signal lamp, for detect cable each point electricity
The voltage transformer of pressure, for carrying out the comparing module of voltage ratio pair, for the feedback cable defective information of this point voltage
Feedback module.
Controller is bi-directionally connected with comparing module, and the outfan of controller is connected with the input of signal lamp.
The input of comparing module is connected with the outfan of voltage transformer, and the outfan of comparing module passes through
Feedback module is connected with the input of microprocessor, and the outfan of microprocessor is connected with the input of signal lamp.
In the present invention, signal lamp includes the greensignal light for sending voltage normal signal and for sending electricity
The red eye of pressure fault-signal.
Before the present invention uses, staff, at failure monitoring platform, is closed when being worked by cable by GPRS communication module
The voltage range of lattice sends to the controller of each Distributed Detection unit, and the qualified voltage interval of reception is sent out by controller again
Delivering in comparing module, the comparison as voltage data is interval.
When the present invention uses, in the Distributed Detection unit that several are equidistantly positioned on cable, voltage transformer is adopted
The real work voltage of each point during collection cable work, and when being worked by cable, the real work voltage of each point sends to comparing
In module, compare with the comparison interval in comparing module, if showing after comparison, the actual work of each point during cable work
Make voltage all in the range of comparison interval, after controller receives virtual voltage qualifying signal, drive the green in signal lamp
Signal lights lights, and red eye cuts out, when representing cable work, and the equal fault-free of each point voltage.
If showing after comparison, during cable work, point or certain some real work voltage is not in the range of comparison interval,
I.e. real work voltage is more than maximum in comparison interval or less than minima in comparison interval, then comparing module is by anti-
Underproof for this point voltage information is sent to microprocessor by feedback module, and microprocessor receives the underproof signal of virtual voltage
After, drive the red eye in corresponding Distributed Detection unit to light, greensignal light is closed, when representing cable work,
This point or this some voltage break down, and by the way, facilitate staff to search fault generation point, after conveniently taking
