Description
Technical field
The utility model relates to distribution line intellectualized technology field, particularly relates to diagnosis and the automatic positioning technology field of distribution line fault.
Background technology
Because power distribution network adopts radial networks, branch is numerous, complex structure, is difficult to looking up the fault point; The practical more mode of searching of current Distribution Network Failure adopts passive method indicator method; So-called passive method is exactly that the singlephase earth fault detecting small current neutral grounding system does not need to be equipped with signal source is carried out detection and fault judgement by indicator itself, the shortcoming major embodiment of this method is that accuracy of data acquisition is lower, directly affects the process of data and the judgement of time; The detection of single-phase grounded malfunction in grounded system of low current is accurately not high, often reports by mistake or fails to report; Along with the requirement of society to power supply reliability is more and more higher, searching problem of distribution line fault, especially the location of low current grounding and the importance of searching manifest, day by day in the urgent need to fundamentally being solved.
Utility model content
The utility model object provides a kind of distribution line intelligent fault positioning system to overcome the deficiencies in the prior art, significantly improves data sampling precision improve various fault model, and introduce signal source method and detect earth fault.
For achieving the above object, the technical solution adopted in the utility model is: distribution line intelligent fault positioning system, is made up of asymmetric current signal source, wall bushing, fault collection indicator, communicating terminal and main station system five part; Described signal source is directly connected with the distribution line three that described wall bushing is drawn; Described fault collection indicator is arranged on distribution line; Described asymmetric current signal source, fault collection indicator, main station system and communicating terminal communicate to connect; The built-in GPRS communication module of described communicating terminal and wireless receiving module, communicating terminal by the data of fault collection indicator by GPRS communication module and wireless receiving module the most at last track data deliver to main station system process and analysis, for accurately location and SMS notification function.
Improve further as the utility model, described fault detector and described communicating terminal distance are less than 50 meters.
Improve further as the utility model, described fault detector is configured for the closed magnetic conduction semi-loop improving sampling precision.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: distribution line intelligent fault positioning system, fault detector adopts can close magnetic conduction semi-loop, the sampling precision of indicator is significantly promoted, for the judgement of fault lays the foundation; The location collecting fault of the fault data of fault detector and the propelling movement of failure message only need complete in 2 minutes, really achieved the intelligent positioning of fault, and the method for indicator carrys out failure judgement point not need pipeline rider to check to scene; Signal source method is used for the singlephase earth fault Real-Time Monitoring of small current neutral grounding system, for the location coordinating fault detector to carry out trouble spot; The Detection accuracy of effective raising single-phase grounded malfunction in grounded system of low current, effectively contracting singlephase earth fault investigation time, reduce loss of outage and add power supply reliability, there is important social benefit and economic benefit.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, distribution line intelligent fault positioning system, mainly comprises signal source, fault detector, communicating terminal and main station system; The built-in primary processor of communicating terminal and power management module, the primary processor of communicating terminal controls fault detector and signal source by power management module; The built-in primary processor of main station system, GIS geography information module and communication module, the primary processor of described main station system is by GIS geography information module communication control terminal, to obtain fault geographic position, the primary processor of main station system, by communication module communication control terminal, notifies staff with short message mode.
The acquisition function of fault detector carrying data, be also the core of this cover system and basic, the precision of therefore sampling has most important effect to whole system; As shown in Figure 2, fault detector adopts the good ferritic stainless steel of magnetic property and be made into semi-loop centered by line of electric force, and make minimum detectable current value be reduced to 1A by 15A, sampling precision is brought up between 3% ~ 5% by 20%; Also add electric field, temperature sensor in indicator, small wireless communication module, not only increase the circuit work information that sampling precision too increases more practicalities;
Data communication is sent to the communicating terminal being less than 50 meters apart by fault detector by 433MHZ small wireless, communicating terminal delivers to main station system through GPRS/GSM again the data received; As shown in Figure 3, communicating terminal adopts high-power (6V/10W) solar panels to carry out supply power supply and be equipped with high-capacity lithium battery (3.6V/10AH) making back-up source, power management module has carried out short circuit, overcurrent to battery, has overcharged, has crossed protections such as putting, ensure the supply of communicating terminal power supply and the serviceable life of battery, ensure that the stable communication of system;
Signal source is mainly used for the detection of singlephase earth fault, signal source is directly connected with distribution line three-phase, be connected with signal source inside by wall bushing as shown in Figure 4, through three electronics PT, high pressure is become low-voltage signal again and deliver to kernel control module analyzing and processing, when circuit generation single-phase earthing, residual voltage can raise and signal source adopts star connections directly can synthesize real-time residual voltage value (scaled low-voltage signal) by three electronics PT, high-pressure vacuum contactor action can be triggered when residual voltage reaches certain value thus create a string characteristic current signal, when namely pointer detection provides earth fault alarm to this current signal.
Main station system mainly carries the analysis of all data that circuit transmits, arrangement, storage work, as shown in Figure 5, and representing analysis result intuitively in conjunction with generalized information system, analysis result is delivered on related personnel's mobile phone by the communication system also by main station system, checks without the need to coming to main website personally.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation; The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
