Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the electric power transmission line intelligent detection device of the present embodiment, comprise governor circuit 1, device for detecting temperature 2, video acquisition module 3, device for monitoring icing 5, microclimate monitoring device 6, conductor vibration detector 8, power module 4, radio-frequency module 9 and wire communication module 10, device for detecting temperature 2, video acquisition module 3, power module 4, device for monitoring icing 5, radio-frequency module 9 are all connected with governor circuit 1 with wire communication module 10, and microclimate monitoring device 6 is connected with governor circuit 1 by wireless communication module 7 with conductor vibration detector 8.
This microclimate monitoring device 6 comprise wind speed and direction monitoring device, rain fall monitor, sunshine monitoring device, aerial temperature and humidity transducer and barometric pressure sensor.This device for detecting temperature 2 is installed on electric transmission line isolator and connecting position of wires front end, is communicated with monitoring unit on subsystem tower by cordless communication network; Device for monitoring icing 5, is installed on insulator and cross arm of tower junction, is communicated with monitoring unit on subsystem tower by wire communication module 10.This conductor vibration detector 8, is installed on transmission line wire, is communicated with monitoring unit on subsystem tower by wireless communication module 7.
A kind of electric power transmission line intelligent detecting method, comprises the following steps:
By conductor vibration monitor 8, microclimate monitoring device 6, device for monitoring icing 5 and device for detecting temperature 2 detect data and deliver to governor circuit 1 and carry out reading process; Governor circuit 1 gather and show Temperature Humidity Sensor 2, the measured value of microclimate condition monitoring transmission line that wind speed and direction monitoring device, barometric pressure sensor record; Measure the electrical characteristics of transmission line, and extract the controling parameters relevant to measured value from the electrical characteristics of transmission line; According to static information, the transmission capacity of measurement result, transmission line, and the sag situation of microclimate condition monitoring transmission line that records of controling parameters and angle of wind deflection; According to the movement position track of the data analysis monitoring transmission line of sag situation and angle of wind deflection; Obtain the maximum weighted situation of transmission line according to the measurement data of movement position track, and monitor aeolian vibration level and the fatigue life of transmission line according to the measurement data of wind speed and direction monitoring device and the measurement data of Temperature Humidity Sensor; The data monitored are delivered in monitor terminal and carries out data analysis, draw the most accurate measured temperature under current state.
The aeolian vibration level of the measurement data of wind speed/wind transducer and the measurement data monitoring transmission line of Temperature Humidity Sensor and fatigue life.Such as, by the Vibration Condition of three dimension acceleration sensor monitoring wire, the vibration frequency of analytic record wire, amplitude, microclimate environmental parameter and the mechanical property parameters of wire own such as the wind speed around combined circuit, wind direction, gas epidemic disaster, on-line analysis judges the level of circuit aeolian vibration and the fatigue life of wire.In wire runs, owing to having superposed vibration on quiet tension force, wire has born the Complicated Loads series be made up of several stress level component, and within the same time that wire runs, each component has different vibration cycles number of times.Estimate that a wire with this load series can apply cumulative damage theory tired useful life.Stress block diagram is the basis of cummulative frequency curve, by carrying out time and frequency domain analysis to transmission line vibration signal data, can estimate the cycle-index of different stress level in the same time.Meanwhile, the size that each frequency component is vibrated can be observed, thus issuable resonance on prevention transmission line, can fatigue life be drawn through estimation.With reference to predict the outcome and the prompting of expertise lab setting, early warning, alarming value can provide maintenance suggestion.Obtain the maximum weighted situation of transmission line according to the measurement data of acceleration transducer, what merge that maximum weighted situation, the measurement data of altimeter and microclimate condition obtain transmission line waves status monitoring result.
When power transmission line meets wind direction and line level angle is greater than the strong wind of 45 degree, whole shelves wire will produce and overallly reverse and swing under the effect of powerful wind-force and the mechanical stress of wire own, this torsion and the swing of wire entirety strengthen gradually along with the effect of lasting wind-force, slowly form oval movement locus.When torsion aggravates and causes wire to carry out significantly bob with lower frequency, at this moment wire to rock phenomenon not fairly obvious, the status and appearance of whole shelves wire is directed undulation, when the abatement of wind, wire progressively will revert to from bob and reverse and swing and weaken gradually until stop.Feature according to waving draws, in early stage and the later stage of waving strenuous exercise, the movement locus of circuit mainly to swing, therefore, the amplitude of certain spot wobble on the angle that Real-Time Monitoring transmission line swings or power transmission line, can play good monitoring and forewarning function to circuit.
Those skilled in the art will be appreciated that; above execution mode is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the appropriate change do above embodiment and change all drop within the scope of protection of present invention.
