Embodiment
For quote and know for the purpose of, the explanation of the technical term hereinafter using, write a Chinese character in simplified form or abridge and be summarized as follows:
GSM:Global System For Mobile Communications, global system for mobile communications.
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 clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to accompanying drawing 1, for the embodiment of the present invention provides a kind of structural representation of line fault monitoring system, this system comprises: line-failure indicator 101, fault information acquisition device 102, global system for mobile communications GSM terminal 103 and monitoring terminal 104, wherein:
Line-failure indicator 101 is arranged on distribution line, in the time detecting that described distribution line breaks down, obtains failure message, and described failure message comprises the abort situation information of described distribution line.
The principle of work of line-failure indicator 101 is as follows:
Refer to Fig. 2, a kind of reproduction providing for the embodiment of the present invention shows earth fault schematic diagram.
Isolating switch 201, line-failure indicator 1 to 12 have been shown in Fig. 2, and wherein 3,6,9 line-failure indicators show malfunction, and All other routes fault detector is shown as normal condition.In Fig. 2, show altogether 6 isolating switchs, no longer in Fig. 2, mark one by one here.
It is as follows that ground connection is detected principle: detect the capacitance current prime minister ripple of ground connection moment and the voltage prime minister ripple of ground connection moment, when the capacitance current of sampling ground connection moment suddenlys change and is greater than default value, and the first half-wave homophase of voltage with ground connection moment, wire voltage-to-ground reduces simultaneously, judge that ground connection occurs circuit, otherwise there is not ground connection in circuit.As Fig. 2, by 3,6, the 9 indicator board turnings demonstrations of 2# line C phase, 12 indicators do not move yet, can judge D point earth fault occurs.Due to the simulated capacitance of sentencing the system of depending on of earth fault, so need provide all outlets of transformer station of distribution line that line-failure indicator is hung to comprise the distance of branch and the distance of cable.
Refer to Fig. 3, a kind of short-circuit detecting schematic diagram providing for the embodiment of the present invention.
Isolating switch 201, line-failure indicator 1 to 12 have been shown in Fig. 3, and wherein 2,3,5,6,8,9 line-failure indicators show malfunction, and All other routes fault detector is shown as normal condition.
According to short circuit phenomenon, have a power failure as action foundation in the direct mutation of transcient short circuit time electric current, protection action.By 2# line B mutually 2,5,8 indicators and 3# line C mutually 3,6,9 indicators turn over red card and show and 11 indicators and 12 indicators board turning not yet, can judge the D point fault that is short-circuited.
Line-failure indicator 101 can be arranged on the feed line of distribution line, accurately detects feeder fault, and sends failure message by GSM network with short message mode.Line-failure indicator 101 is that a kind of load current that adapts to changes, the relevant failure detector of short-circuit current component during only with fault.Its criterion is more comprehensive, can greatly reduce the possibility of misoperation.As changed when system operating structure, when load becomes large; When there being large load switching, when the throwing people of large induction-motor load; In the time there is in short-term excitation surge current in system; When having high input after load, while artificially power failure, all can effectively identify and be failure to actuate, while only having short circuit current flow, just provide indicating fault.
