Be further described below in conjunction with the detailed construction of the drawings and specific embodiments to utility model.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is circuit diagram of the present utility model.
Embodiment
As shown in drawings: a kind of family expenses electric leakage alarm device, it comprises insulation crust inside 1, rectifying and voltage-stabilizing filtering circuit 2, warning Analogous Integrated Electronic Circuits 3, Three-hole socket 4.
Described rectifying and voltage-stabilizing filtering circuit is made up of I resistor R1, I diode VD1, light emitting diode VD2, II diode VD3, electric capacity C.
Described warning Analogous Integrated Electronic Circuits is made up of integrated package A, II resistor R2, electroceramics sheet B.
Described Three-hole socket 4 be positioned at insulation crust inside 1 high order end, described rectifying and voltage-stabilizing filtering circuit 2 is positioned at the centre of insulation crust inside 1, I resistor the left side connect with the ground terminal XS of Three-hole socket 4, the right of I resistor R1 connects with the left side of I diode VD1, the right of I diode VD1 connects with the left side of light emitting diode VD2, the right of light emitting diode VD2 connects with the top of II diode VD3, electric capacity C and II diode VD3 is in parallel, the top positive pole of electric capacity C connects with the top of II diode VD3, the below negative pole of electric capacity C connects with the below of II diode VD3, described warning Analogous Integrated Electronic Circuits 3 is positioned at the rightmost of insulation crust inside 1, the upper left side of integrated package A connects with the top positive pole of electric capacity C, directly over integrated package A, the left side also connects with the top positive pole of electric capacity C, directly over integrated package A, the right connects with the left side of II resistor R2, the right of II resistor R2 connects with the upper right side of integrated package A, the lower right of integrated package A connects with the below of electroceramics sheet B, the top of electroceramics sheet B connects with the left side, top of integrated package A, connect with the below negative pole of electric capacity C immediately below integrated package A, the lower left sky of integrated package A connects, the below negative pole of electric capacity C, the zero line side of Three-hole socket 4 is connect immediately below the below of II diode VD3 and integrated package.
Principle of work of the present utility model and using method are: at ordinary times, because the left end of I resistor R1 connects with the ground terminal XS of Three-hole socket 4, therefore warning circuit is without working power, light emitting diode VD2 is not luminous, B is noiseless for electroceramics sheet, once the ground terminal XS of the household electrical appliance access Three-hole socket 4 of metal shell electric leakage, leakage current just can pass through live wire, the metal shell of household electrical appliance, the ground wire stomidium of Three-hole socket 4, warning circuit and electrical network zero line form loop, leakage current is by I resistor R1 current limliting, after I diode VD1 half-wave rectification, light emitting diode VD2 is lighted, meanwhile, leakage current is by II diode VD3 voltage stabilizing, 5V DC voltage is exported at its two ends, after electric capacity C filtering, the simulated sound generator of integrated package A and II resistor is done, electroceramics sheet B will send police whistle sound, reminding user keeps in repair the timely power-off of electrical equipment, during use, according to a conventional method warning Three-hole socket 4 is accessed 220V mains circuit, should be specifically noted that the live wire of power lead, zero line position can not connect instead, otherwise do not have electric leakage alarming effect.
