Description
Technical field
The utility model relates to the distribution automation technical field, is specifically related to a kind of distribution fault automatic location system.
Background technology
Along with improving constantly of development and national economy and people's material and culture level, electric utility develops rapidly, and electrical network constantly enlarges, and topological structure is increasingly sophisticated.In order to make line work more reliable, positions such as pole line, power cable, bin, ring main unit generally all can be equipped with fault detector, are used to indicate faults such as grid short circuit and single-phase earthing.Traditional fault detector only has the alarm indication function, i.e. all fault detectors equal board turning or the flash of light indication of faulty line from transformer station's outlet to the trouble spot, and the fault detector behind the trouble spot is failure to actuate.After breaking down, the track walker need trigger along faulty line from transformer station and find the fault detector of last action and the interval that first fault detector that does not move constitutes just can find the fault zone.The required spended time of this mode troubleshooting is longer, and the wasting manpower and material resources is difficult to fix a breakdown rapidly, and power supply reliability can not obtain good assurance.
Summary of the invention
To the problems referred to above, the utility model provides a kind of automatical and efficient distribution fault automatic location system, and this system can provide the indication information of abort situation and fault-time in time, helps the maintenance personal to fix a breakdown rapidly, improves power supply reliability greatly.
The utility model is that the technical scheme that its technical matters of solution is adopted is:
The distribution fault automatic location system; Comprise the fault detector that is arranged in transformer station's outlet and the circuit branch; Also comprise the substation that is distributed in the fault detector close position, the central station that is connected with the substation communication and the master station that is connected with the central station communication; Be provided with communication unit in the said fault detector, fault detector is communicated by letter with the substation through communication unit and is linked to each other.
As preferred embodiment, said substation is connected with the central station communication through GSM network or GPRS network.
As preferred embodiment, said fault detector comprises phase fault probe unit and earth fault detection unit, and the output terminal of phase fault probe unit and earth fault detection unit is connected with communication unit.
As preferred embodiment, the distribution fault automatic location system comprises signal source, and the output terminal of said signal source is connected with the transformer station outlet.
The beneficial effect of the utility model is: the utility model is set up based on fault detector technology, the communication technology and geographic information system technology; Formed one between fault detector, substation, central station and the master station and covered complete trouble spot detection and positioning system; In case break down in the electrical network, this failure message can in time feed back on the master station, and master station obtains the fault geographical location information to this information analysis; Assist the maintenance personal directly to fix a breakdown to the abort situation point; Improve power supply reliability greatly, significantly reduce the fault track walker simultaneously, increase work efficiency.
Description of drawings
Further explain below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the composition synoptic diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1; The distribution fault automatic location system of the utility model; Comprise the fault detector 1 that is arranged in transformer station's outlet and the circuit branch; Also comprise the substation 2 that is distributed in fault detector 1 close position, the central station 3 that is connected with substation 2 communications and the master station 4 that is connected with central station 3 communications, be provided with communication unit in the said fault detector 1, fault detector 1 links to each other with substation 2 communications through communication unit.In order to make native system can be used for phase fault and singlephase earth fault detection simultaneously; Fault detector 1 comprises phase fault probe unit and earth fault detection unit, and the output terminal of phase fault probe unit and earth fault detection unit is connected with communication unit.System generally also is provided with signal source 5 during detection of ground faults, and the output terminal of said signal source 5 is connected with the transformer station outlet, can distinguish phase fault and earth fault easily after being provided with this signal source.
When fault took place, fault detector can detect short-circuit current or the signal specific electric current flows through, the fault detector action, and it sends actuating signal to the substation of close position and preset correspondence through communication unit and substation short haul connection.Usually, the substation is installed on the bifurcation of circuit, and correspondence can be preset with a plurality of (as 6, respectively on the 6 phase circuits that connect a branch) fault detector in each substation, and promptly the action message of these a plurality of fault detectors generations is carried out transfer through this substation.For overhead system, fault detector is generally communicated by letter with the substation through short-range wireless systems, between substation and the fault detector at a distance of about 2 ~ 10m.
Central station is issued with the fault detector address information of action branch in the substation after receiving action message, wherein, the communication between substation 2 and the center website 3 can be carried out through GSM network or GPRS network.Central station is handled it after must arriving the information of bringing the substation, gives master station with result and shows.Master station is according to these action messages of receiving from central station; Carry out the network topology computational analysis, combine, can directly demonstrate the trouble spot geographical location information with GIS-Geographic Information System; And on geographical background, show, can also print geographical location information.The operating maintenance personnel can directly fix a breakdown to the trouble spot.
The fault detector of the utility model can also further be provided with board turning demonstration identical with traditional fault detector or flash of light Presentation Function, and the convenient for maintaining personnel navigate to fault section quickly, carry out maintenance job more efficiently.The embodiment of the utility model is not restricted to the described embodiments, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
