Description
Technical field
The present invention relates to a kind of omnipotence safety plug with the ground wire electrification warning device.
Background technology
Omnipotence safety plug, generally comprise belt switch phase, zero, three utmost points, be located at zero sequence current mutual inductor, test loop, amplifying circuit, rectifier, controllable silicon, release between phase, the zero line, ground wire is connected with fixed contact by the movable contact flexure strip, be installed with zero sequence current mutual inductor in the ground wire, it has or not the residual current except detecting between load phase, the zero line, and whether also detect ground wire charged.When phase line, zero line or ground wire broke down respectively or simultaneously, two magnetic test coils all can make release immediately phase, zero, ground wire all be disconnected, and promptly cut off the electricity supply, thereby have ensured personal safety effectively, therefore are used widely in household electrical appliance.
Though existing omnipotence safety plug prevents the danger of getting an electric shock in case electric leakage can be played, but still can not clearly know phase line, zero line or ground wire electrification, be unfavorable for fixing a breakdown, eliminate the potential hazard of getting an electric shock, therefore, can in time cut off circuit when not only requiring ground wire electrification for improving the fail safe of omnipotence safety plug, more the ground wire electrification warning device to be set, caution user ground wire leaks electricity, so that in time get rid of this potential hazard, guarantees safe in utilization.Existing omnipotence safety plug does not then have warning device.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned defective of prior art and a kind of omnipotence safety plug with the ground wire electrification warning device is provided, it can in time be cut off under the ground wire electrification situation and can in time report to the police, stop using with the caution user, in time get rid of leak current fault, thereby prevent the generation of electric shock accidents, ensure safe in utilization.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
The omnipotence safety plug of band ground wire electrification warning device; comprise the ground, zero of each belt switch, mutually three-way wiring and the earth leakage protective device of forming by zero-sequence transformer, release, amplifier, rectifier, test loop and controllable silicon; it is characterized in that: connect a sound and/or flash alarm circuit and optoelectronic switch between the input pin end of described zero, phase two wires; connect a lead-out wire behind described ground wire input pin end series resistor and the neon lamp, neon lamp and optoelectronic switch are packaged together.
When above-mentioned omnipotence safety plug used with electrical equipment, lead-out wire was connected with body of wall or ground wire.When local tape was electric, the earth leakage protective device action disconnected the switch on the ground wire, thereby cut-out electrical equipment is charged.Produce voltage between ground wire plug end and body of wall simultaneously and light neon lamp, neon lamp triggers the optoelectronic switch conducting, thereby voice guard and/or flash alarm are reported to the police, and reminds user's electric wire charged, needs in time to get rid of the potential safety hazard of ground wire electrification.
Compared with prior art, the invention has the advantages that: by the ground wire electrification warning device is set in omnipotence safety plug, strong caution user ground wire is charged when ground wire electrification is cut off the electricity supply, the user is concentrated on this potential safety hazard of ground wire electrification also can in time get rid of, thereby eliminate personal safety hidden danger.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1 is the application of omnipotence safety plug in electric heater of band ground wire electrification warning device; the photosensitive switch 6 that is connected an audible-visual annunciator 3 and optoelectronic switch at the input pin end L utmost point that all can protect plug 1 of band ground wire electrification warning device with the N interpolar; be connected with body of wall after neon lamp 5 two end that connect optoelectronic switch 4 at the input pin end E utmost point and the resistance R, neon lamp 5 and photosensitive switch 6 are packaged together and have constituted optoelectronic switch 4.Neon lamp 5 one ends of optoelectronic switch 4 are connected with the input ground wire of earth leakage protective device, and the other end is connected in series with resistance R, and the other end of resistance R is connected with body of wall.
Above-mentioned neon lamp 5 and photosensitive switch 6 are packaged together, and can prevent the interference of extraneous light to circuit.
During normal the use,, therefore can not report to the police because photosensitive switch disconnects.
When the L utmost point and N were extremely unusual, the L utmost point and the N utmost point were cut off in the earth leakage protective device action, but since this moment warning circuit still disconnect, alarm still can not reported to the police.
When local tape is electric; because ground wire is to be connected on the shell of electric heater 1; the shell of electric heater is fixed on the body of wall; will produce certain leakage current by body of wall and the earth when local tape is electric; omnipotence safety plug 1 will trip after detecting leakage current at once; make connected electric heater 2 outages; thereby protection personal safety; produce simultaneously a very high voltage between the ground wire E utmost point and body of wall, light neon lamp, neon lamp is luminous to make photosensitive switch 5 conductings; power firestreak L; voltage between zero line N will be loaded into the two ends of audible-visual annunciator; thereby audible-visual annunciator is reported to the police, remind user's ground wire charged strongly, need in time to get rid of potential safety hazard.
The resistance R of above-mentioned and neon lamp 4 serial connections also can be connected with the E utmost point of output in the omnipotence safety plug, during use, the ground line output terminal of omnipotence safety plug is connected with the shell inner bag of electric heater 2, and the shell of electric heater 2 is fixedlyed connected with body of wall, see Fig. 4, the same Fig. 1 of its alarm principle.
Fig. 2,3,5,6 further implements circuit, optoelectronic switch be one by neon lamp E and the photosensitive coupling circuit that photo resistance R is sealed and combines, sound light alarming circuit is made up of rectifier diode D, step-down current-limiting resistance R1, filter capacitor C and flash tube LED or buzzer B, connects with rectifier diode D, step-down current-limiting resistance R1 after filter capacitor C and flash tube LED or the buzzer B parallel connection.
After the local tape leakance non-electricity protector tripping operation outage; voltage difference between ground wire input and the body of wall can make neon lamp between the two light; photo resistance R is not seeing the light time; its resistance value is very big; approach infinity; see the light of neon lamp as photo resistance R after; its resistance value can diminish rapidly; because of flash tube LED or buzzer B be attempted by live wire L, zero line N two ends after diode D resistance R 1 photo resistance R is connected in series; so the electric current by flash tube LED or buzzer B also can increase rapidly, thereby make flash tube LED continue flash of light or buzzer call warning.
At filter capacitor C two ends shunt resistance R2 in parallel, at neon lamp 4 two ends R3 in parallel is in order to prevent false alarm.
The R5 voltage that can make photo resistance R two ends after the dividing potential drop of connecting with R1 reduces, and meets the withstand voltage scope that photo resistance R can bear.
Can also be flashing diode LED and voice guard B serial or parallel connection simultaneously in above-mentioned each circuit, owing to be the increase or the replacement of common part, structural representation no longer draws.
