Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, RG is an optocoupler among the figure, and optocoupler is made up of camera bellows, neon lamp and photo resistance, and neon lamp and photo resistance place camera bellows, open an aperture on the camera bellows.LED is a flash tube, and D1 is a rectifier diode, and R1, R2, R3, R4 are resistance, and C1 is an electrochemical capacitor, and K1, K2, K3 are switch.
The omnipotence safety plug of band warning device, comprise the ground, zero of each belt switch, mutually three-way wiring, described flash alarm circuit be connected between the input pin end of phase line L, zero line N after photo resistance among the optocoupler RG is connected in series, the two ends of described neon lamp are in parallel with resistance R 4, connect with resistance R 3 then, the two ends after the series connection are connected between the zero line N, ground wire E input pin of power supply.
Above-mentioned flash alarm circuit is made up of rectifier diode D1, step-down current-limiting resistance R1, electrochemical capacitor C1 and flash tube LED, its positive pole of the corresponding positive and negative back in parallel of the positive and negative electrode of electrochemical capacitor C1 and flash tube LED is connected with rectifier diode D1 negative pole with step-down current-limiting resistance R1 series connection back, and the negative pole of electrochemical capacitor C1 and flash tube LED is connected with an end of photo resistance.
Rectifier diode D1 positive terminal in the above-mentioned flash alarm circuit, the other end of photo resistance are connected respectively with between the live wire L of power supply, the zero line N input pin end.
Above-mentioned electrochemical capacitor C1 and photo resistance two ends divider resistance R2. also in parallel can reduce the voltage of photo resistance two ends in the optocoupler like this, prevent to damage inadequately because of photo resistance is withstand voltage.
Above-mentioned neon lamp two end parallel resistance R4 are because of resistance R 4 dividing potential drops prevent false alarm.
During normal the use, because photo resistance R is not seeing the light time that its resistance value is very big, therefore approach infinity can not report to the police.
When phase line L and zero line N were unusual, phase line L and zero line N were cut off in the earth leakage protective device action, but since this moment optocoupler still disconnect, flash alarm still can not reported to the police.
When local tape is electric, produce high voltage between ground wire and the zero line, the neon lamp that be connected in the optocoupler between ground wire and the zero line this moment is lighted, photo resistance in the optocoupler is receiving the light time that neon lamp sends, the conducting that diminishes of the resistance value of photo resistance, thereby cause power supply L, N produces direct voltage after rectifier diode D1 rectification, this direct voltage passes through resistance R 1 and R2 dividing potential drop again, voltage after partial behind electrochemical capacitor C1 filtering cumulative through flash tube LED and photo resistance, make flash tube LED energising point intense flash, the strong user's ground wire of reminding is charged, needs in time to get rid of potential safety hazard.
Above-mentioned flash tube LED also can be buzzer, reports to the police by sounding, and perhaps flash tube LED and buzzer B serial or parallel connection are reported to the police simultaneously by flash of light and sound, owing to be the increase or the replacement of common part, circuit diagram no longer draws.
Fig. 2 is another embodiment, RG is an optocoupler among the figure, optocoupler is made up of camera bellows, neon lamp and light-sensitive element, and neon lamp and light-sensitive element place camera bellows, opens an aperture on the camera bellows, LED is a flash tube, D1 is a rectifier diode, and R1, R2, R3, R4, R5, R6, R7 are resistance, and C1 is an electrochemical capacitor, Q is a triode, and K1, K2, K3 are switch.

During normal the use, because photo resistance R is not seeing the light time that its resistance value is very big, approach infinity, photosensitive switch disconnects, and therefore can not report to the police.
When phase line L and zero line N were unusual, phase line L and zero line N were cut off in the earth leakage protective device action, but since this moment optocoupler still disconnect, flash alarm still can not reported to the police.
During local tape electricity, produce high voltage between ground wire and the zero line, be connected between ground wire and the zero line neon lamp in the optocoupler and lighted, this moment, the resistance of light-sensitive element changed along with the luminous power of neon lamp.Power supply L, the direct voltage of N line after diode D1 rectification are through resistance R 6, R7 dividing potential drop, voltage after partial is passed through light-sensitive element and resistance R 5 dividing potential drops again, when the neon lamp luminous intensity strengthens, the light that light-sensitive element receives is just strong more, cause the resistance of light-sensitive element to diminish, raise thereby make, when magnitude of voltage is increased to 0.7V and when above, triode Q is switched on through light-sensitive element and resistance R 5 voltage after partial values.After the triode Q conducting, power supply L, the direct voltage of the N utmost point after diode D rectification are through resistance R 1, R2 dividing potential drop, voltage after partial behind electrochemical capacitor C1 charging cumulative through flash tube LED and triode Q, flash tube LED energising is lighted continue flash of light, the strong user's ground wire of reminding is charged, needs in time to get rid of potential safety hazard.
Above-mentioned flash tube LED also can be buzzer, reports to the police by sounding, and perhaps flash tube LED and buzzer B serial or parallel connection are reported to the police simultaneously by flash of light and sound, owing to be the increase or the replacement of common part, circuit diagram no longer draws.
Compare with last embodiment, only when the magnitude of voltage of ground wire electrification reach a certain height, flash tube was just understood flashing light alarm to present embodiment, thereby prevented that effectively warning circuit from disorderly reporting to the police, false alarm.
For preventing that better warning circuit from disorderly reporting to the police, false alarm, also at resistance R 7 two ends electrochemical capacitor C2 in parallel.
