Description
Technical field
This utility model belongs to overhead distribution fault diagnosis technology field, is specifically related to the automatic switching control equipment of fault detector flash of light instruction.
Background technology
Current domestic overhead distribution fault section diagnosis all adopts fault detector to carry out fault location, after fault occurs, fault detector utilizes battery electric quantity to drive one to turn over disk control unit and several highlighted red LED lamp flicker being arranged on shell transparent part carries out indicating fault.When having fault, turning over disk control unit upset to red status, whether LED carries out slow flash simultaneously, also can be broken down by this fault detector position of the glint identification of highlighted red LED when facilitating break down night；During fault-free, turn over disk control unit and cancel red rollover states, extinguish LED flicker simultaneously.
But when occurring due to overhead distribution fault, generally patrol and examine maintenance time all long, for ensureing that line data-logging personnel can find fault, generic failure indicator all keeps fault to turn over when breaking down and LED glistened more than 24 hours, even has and reaches 72 hours.Owing to fault detector is generally open air self-contained unit, general individually employing lithium piezoelectric battery is powered, or adopts the mode that solaode power taking adds the integration of lithium piezoelectric battery to be powered.Turn over disk control unit owing to utilizing electric magnet principle, turn over for a long time and be not required to keep Electromagnetic Control is powered, but LED flickering position is as kept 24 hours glistening, and it must be carried out pulse power supply, retention time is more long, and its power consumption is also more many.Such as the state of taking place frequently that breaks down, the inevitable battery electric quantity of causing trouble indicator own quickly exhausts, and substantially reduces the fault detector life-span itself.
During daytime, being affected by sunlight, during LED flicker, human eye seems inconspicuous, and line data-logging personnel turn over each through redness and identify fault, it is contemplated that cancels LED flash of light power supply, just opens LED flicker to evening, facilitate line data-logging personal observations.As improved by such mode, when fault occurs, LED scintillation time can shorten more than half, greatly reduces the loss to battery electric quantity, improves the fault indicator life-span.How to identify that day and night is exactly the key of this problem.
Clock can be added, by setting a time point, for instance whether at 18 in afternoon switches over glistens at the microprocessor within fault detector.There are the following problems to add the method for clock: being both needed to when (1) each fault detector dispatches from the factory or when installing it is carried out time service step, impact produces installation effectiveness；(2) certain time set is likely to be due to install local difference and causes there is error, and namely some local sunshine-duration is partially long, it is possible at 19 in afternoon yet non-darkness, so just cause still opening LED flicker in advance, battery electric quantity also suffers from some impacts；(3) microprocessor internal time error problem, in general, error is relatively big, and long-play may result in time cumulation error and is likely to be breached several hours or 10 several hours, same impact effect；(4) as increased clock chip inside fault detector, owing to accurate clock chip price general charged is higher, economic worth is not high.
Light-sensitive device can be installed additional to fault detector, utilize the characteristic of light-sensitive device to identify day and night, thus the problem effectively solving time service, area error at sunshine, clock accuracy aspect.But fault detector shell needs light-sensitive device to be exposed to visible ray place, it is possible to the problem that need to relate to shell mechanism change aspect；It is additionally, since light-sensitive device light unicity, it is possible to situation about being blocked by leaves or other shelters occurs in fault detector actual installation process, makes light-sensitive device ineffective.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but detailed description of the invention of the present utility model is not limited to this.
Embodiment
The automatic switching control equipment of the fault detector flash of light instruction that the utility model proposes, utilizes the power taking characteristic of solar panels of fault detector self to control LED flashing light state.When solar panels light irradiation on daytime, solar panels outfan has the characteristic that voltage exports, and LED does not glimmer；When entering night, solar panels Non voltage output, now open LED flicker, facilitate line data-logging personal observations.
As shown in Figure 1, this utility model automatic switching control equipment includes solar panels, bleeder circuit, ON-OFF control circuit, microprocessor, accumulator and LED, solar panels, bleeder circuit, ON-OFF control circuit, LED are sequentially connected with, and microprocessor is connected with LED.
Referring to Fig. 2, bleeder circuit mainly includes divider resistance R1, R2 of being in series, and the input of bleeder circuit is connected with the outfan of solar panels, and the outfan of bleeder circuit is connected with ON-OFF control circuit.ON-OFF control circuit mainly includes audion Q1, audion Q2 and PNP pipe Q3.The base stage of audion Q1 is connected through the series connection point of resistance R3 with divider resistance R1, R2, and colelctor electrode is connected through the base stage of resistance R5 with audion Q2；The colelctor electrode of audion Q2 is connected with the base stage of PNP pipe Q3, and the colelctor electrode of PNP pipe Q3 is connected with LED, and the emitter stage of PNP pipe Q3 is connected with accumulator.The Pulse Width Control port of microprocessor is connected with LED.3.6V accumulator is dodged turn off the light and microprocessor power supply to audion Q1, audion Q2, PNP pipe Q3, LED.
The outfan of solar panels accesses two divider resistances R1, R2, and when daytime, during solar panels cell output voltage, the bleeder circuit of R1, R2 composition is divided into a voltage signal that can control audion Q1 conducting this output voltage.After audion Q1 conducting, colelctor electrode level is 0, and audion Q2 base voltage is 0, so Q2 is not turned on；Audion Q2 colelctor electrode level is high, and the base level of PNP pipe Q3 is high, and ON-OFF control circuit is not turned on, LED flash positive pole Non voltage output.During night, PNP pipe Q3 base voltage is pulled low, therefore PNP pipe Q3 is in the conduction state, and now cell voltage is powered to LED either directly through PNP pipe Q3, and as now fault detector is malfunction, microprocessor will control LED flicker in a pulsed fashion；Such as now fault-free, microprocessor controls end output high level, makes LED be in OFF state.
