Application number be 2013107494915 patent discloses a kind of failure detection device for power transmission line, it comprise secondary phase current collection circuit, secondary line voltage collection circuit, receive collection signal ADC chip, judge the primary controller of line fault, remote signalling testing circuit, the remote control output circuit of gauge tap action, the extraneous telecommunication circuit of detector switch state.This device converts collection secondary phase electric current, secondary line voltage, phase shift, alternating current-direct current carry out analytical calculation after transforming, and judge whether transmission line of electricity breaks down according to result of calculation.Its shortcoming is complex structure, cost is high, installation is inconvenient, troublesome poeration.Application number be 2009100681736 patent discloses a kind of wireless detecting system based on ultra-high-tension power transmission line, it is made up of acquisition terminal, monitoring sub-station, monitoring gateway, internet and Surveillance center, acquisition terminal to be connected with sub-station for detection by Zigbee protocol and to form wireless monitor subnet, be connected between monitoring sub-station and between monitoring sub-station with monitoring gateway by WiFi agreement and form wireless monitor backbone network, monitoring gateway is connected with Surveillance center by internet.This system can carry out collection and the transmission of polytype parameter to ultra-high-tension power transmission line.But it affects by Internet service and communication quality thereof, easily interrupt losing efficacy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for the device of transmission line malfunction instruction with alarm, and this apparatus structure is simple, does not affect by extraneous factor, reliable.
For solving the problem, technical solution adopted in the utility model is: a kind of transmission line malfunction instruction and alarm device, comprise harvester and main website server, described harvester comprises housing and is positioned at the microprocessor of housing, described microprocessor is connected with signal amplification circuit and teletransmission transmitter module in turn, described teletransmission transmitter module is connected with main website server by teletransmission receiving trap, and described main website server is connected with audible-visual annunciator.
Described microprocessor adopts digital microprocessor.
Described main website server is computer.
The SMS platform of described main website Servers installed and mobile phone automatic interaction.
Described housing is enclosed water-proof structure, and outside surface scribbles water-proof coating.
The beneficial effects of the utility model are:
1, sensor technology, measuring technique and distant communication technology combine together by the utility model, compared with prior art, not only increase the load monitoring function for overground cable, communication module remote alarm and localization of fault can also be passed through, substantially increase localization of fault promptness and accuracy, save a large amount of manpower and materials.
2, main website of the present utility model server is combined with a large amount of field erected watch-dog and telecommunication devices, after fault occurs, can accurately indicate fault type, fault-time, fault parameter and fault section in a few minutes; Failure message also can be sent to related personnel with short message mode by SMS platform simultaneously.Be conducive to repair personnel and rush towards scene rapidly, fix a breakdown, shorten the fault outage time, improve power supply reliability and first-aid repair efficiency.

Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, transmission line malfunction instruction of the present utility model and alarm device, transmission line malfunction instruction and alarm device, comprise harvester and main website server, described harvester comprises housing 1 and is positioned at the microprocessor 2 of housing 1, described microprocessor 2 is connected with signal amplification circuit 3 and teletransmission transmitter module 4 in turn, described teletransmission transmitter module 4 is connected with main website server 6 by teletransmission receiving trap 5, described main website server 6 is connected with audible-visual annunciator 7, for reminding managerial personnel's Timeliness coverage and process.Described microprocessor 2, for Collection, can adopt digital microprocessor.Described main website server 6 is computer.Described main website server 6 arranges the SMS platform with mobile phone automatic interaction, can overhaul specific responsibility personnel short message alarm, to overhaul in time at any time to trouble spot affiliated area.Described housing 1 is enclosed water-proof structure, and outside surface scribbles water-proof coating (not shown), can prevent rain erosion, extends the serviceable life of the instruction of this transmission line malfunction and alarm device.
This device is applicable to the Monitoring and Positioning of the fault such as short circuit, ground connection, decompression of 10kV, 35kV distribution line, only described harvester need be arranged on the position of joints of distribution line branch in use, its power supply can be drawn by mutual inductor low-pressure side, also configurable inductive power supply device.Microprocessor is by gathering 10kV(35kV) real-time current, the magnitude of voltage of overground cable, and judge that cable is ground connection, short circuit or no-voltage fault.If fault occurs, amplified by signal, by teletransmission transmitter module warning message passed to main website server and according to data results determination fault section.Measuring technique then mainly comprises short trouble judgement, short trouble confirms and earth fault judges.Short trouble judges and short trouble confirms by arranging threshold value di/dt or IMAX, after threshold value is surpassed, and more than loss of voltage 100ms simultaneously.Earth fault judges it is then residual voltage Vo by the residual voltage Vr(=in detection of ground faults 3 times) with aftercurrent Ir(=3 zero-sequence current Io doubly) the phase place of these two parameters of transients.Vo and Io is anti-phase: fault is positioned at downstream, monitoring point; Vo and Io homophase: fault is positioned at upstream, monitoring point.This apparatus structure is simple, cheap, and system is independent not to be affected by extraneous factor, and usability is reliable, can in time with accurately to localization of fault, realize accurately locating, greatly lifting line walking work efficiency.
