Description of drawings
Fig. 1 is the structured flowchart of a kind of embodiment of the utility model electrification in high voltage indicating device.
Fig. 2 is the structural drawing of sensor in the utility model electrification in high voltage indicating device.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
See also Fig. 1, Fig. 1 is an example structure figure of the utility model electrification in high voltage indicating device.This electrification in high voltage indicating device comprises sensor 11, analogue amplifier 12, AD collector 13, controller 14 and warning indicator 15, and said sensor 11, analogue amplifier 12, AD collector 13, controller 14 and warning indicator 15 are electrically connected successively.
Said sensor 11 is used to monitor high-voltage signal, and promptly when not having high-voltage signal, this sensor is in a steady-working state; When getting into regional that high-voltage signal involves (zone with electromagnetic field), the electromagnetic field signal that high-voltage signal produces can make and the duty change of sensor 11 cause the signal of sensor output to change.
Preferably, said sensor 11 adopts coil pickoff.Said sensor 11 comprises an iron core 116; Primary coil 111 and secondary coil around said 116 windings unshakable in one's determination; Said primary coil two ends are connected in series a power supply 114, and said secondary coil two ends are electrically connected with said analogue amplifier 12, are used to export induction electromotive force.Said power supply 114 can be primary coil 111 a stable electromotive force is provided; A stable induction electromotive force
will be exported in the secondary coil two ends; When this sensor entered into the electromagnetic field of high-tension electricity generation, said induction electromotive force
will change.
Said analogue amplifier 12 is used for the signal of sensor 11 outputs is carried out the filtering amplification, and then signal is transferred to AD collector 13.
Said AD collector 13, the signal that analogue amplifier 12 is transmitted carries out analog to digital conversion, is input in the controller 14 after converting digital signal to.
Said controller 14 is analyzed the digital signal that receives, and is judged whether to monitor high-voltage signal according to analysis result, when having monitored high-voltage signal, just controls the warning indicator 15 indication work of reporting to the police.
Said warning indicator 15 can be the LED lamp for any device of the indication of can reporting to the police, when monitoring high-voltage signal, and the warning of glimmering that controller 14 may command LED lamps do not stop; This warning indicator 15 also can be audible alarm unit, and when monitoring high-voltage signal, this voice guard of controller 14 may command sends alarm sound.
In the above technical scheme; In order to strengthen the intensity of monitor signal; Preferably; Said secondary coil comprises the first different coil 112 of the number of turn and second coil 113, and an end of said first coil 112 is connected with an end of second coil 113, and the other end of the other end of said first coil 112 and second coil 113 is electrically connected with said analogue amplifier 12.The induction electromotive force
