Numerous data and electrical network practical operating experiences show, the tripping operation of grid power transmission line fault has 40% or more and caused by thunderbolt, and extreme case can be near 80%, and the successful reclosing rate of being struck by lightning is lower, only is 46.7%.Electric pressure is low more, and lightning fault tripping operation ratio is high more.In recent years, along with socioeconomic fast development, transmission line of electricity that outside destroy causes tripping operation ratio is more and more higher, has become the second largest factor that is only second to lightning fault, and wherein the accident that causes with crane construction etc. is in the majority.For the line fault of unsuccessful reclosing, by existing management and running rules, require to send by force once immediately, to restore electricity as far as possible, guarantee the stabilization of power grids.Must force to send electricity for the fault that natural causes such as thunderbolt, pollution flashover, bird pest cause, if but for the fault that artificial origin's outside destroy causes, give the life that may jeopardize the people in such cases by force, serious social influence caused.So be necessary the tripping operation that different reasons cause is treated with a certain discrimination.Difference lightning fault and common short circuit are aided with company's electric network thunder and lightning positioning system, accurately judge lightning fault, so that take different accident treatment measures.
Angle from electric system, thunder and lightning has become the main reason of electric power system fault, no matter be circuit, transformer station or consumer, the impact that how to make them can better resist the electromagnetic transient that thunder and lightning and lightning induction produce is the problem of being concerned about the most in the electric system lightning protection, this need be based upon that parameters to the discharge process of thunder and lightning and lightning current has fully realizing and the basis understood on.
Research to the lightning current characteristic parameter at present mostly relies on simulation and method of emulation, and to natural lightning current parameter, comprises that waveform, amplitude, rise time, duration etc. all lack real data.How can obtain real lightning current data, this research for the understanding of thunder discharge process and lightning current and spatial field thereof is all very meaningful.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defective, the lightning monitoring scope is wide, and can improve the atmosphere overvoltage intrusion ripple monitoring system of lightning monitoring distance and precision.
The technical scheme that its technical matters that solves the utility model adopts is: the ripple monitoring system is invaded in a kind of atmosphere overvoltage, comprise electrical network bus, transmission line of electricity and be separately positioned on voltage transformer (VT) summation current transformer on electrical network bus and the transmission line of electricity, it is characterized in that: also comprise data collector, communication device and data analysis set-up, data collector connects the voltage transformer (VT) summation current transformer respectively, output terminal connects the input end of communication device, and the output terminal of communication device is connected with data analysis set-up.
Described data collector comprises high-frequency data harvester, low-frequency data harvester and data processor, the high-frequency data harvester with connect data processor again respectively after the low-frequency data harvester is connected the voltage transformer (VT) summation current transformer respectively.
Described communication device is the Ethernet bridge and the communication server, and Ethernet bridge connects the communication server.
Described data analysis set-up is a PC.
When line failure, fault thunderbolt or non-fault thunderbolt, the transient state travelling wave signal that high-frequency data harvester and low-frequency data harvester produce when gathering transmission line fault and thunderbolt, and signal uploaded to data processor, data processor is transferred to the communication server with data by Ethernet bridge after data are analyzed, the communication server is connected with PC, and data are analyzed and shown.According to the transient state travelling wave signal that collects, the electrical equipment malfunction and the non-thunderbolt electrical equipment malfunction electric characteristic amount that cause by thunderbolt, correct electrical network lightning fault and the non-lightning fault distinguished, the Lightning Over-voltage of real-time follow-up internal overvoltage and invasive system is to the influence of grid equipment.
The beneficial effect that the utility model had is: monitoring range is wide when breaking down, when being arranged, lightning fault improves lightning monitoring distance and precision greatly, and can catch fault thunderbolt and non-fault thunderbolt in real time, clearly distinguish fault thunderbolt and non-fault thunderbolt, analyze the influence that thunderbolt causes electrical equipment, for equipment state overhauling proposes guiding suggestion.
