Background technology
Some electric equipment, needs automatically to remind in time, to inform that administrative staff get rid of line fault as early as possible when occurring therefore have a power failure in AC power.In the area often had a power failure, the thing not connecting electrical appliance power supply in time because of a variety of causes after power failure happens occasionally, after some equipment has a power failure, electrical appliance is provided with automatic closing function, need manual intervention just can recover normal work, as: poultry electricity incubation equipment, once have a power failure and can not be found in time, gently then cause poultry hatching to bring out rate and reduce, heavy then cause very large economic loss; For another example: the electrical heated appliances such as electric iron, once have a power failure restore electricity again after, be easy to bury disaster hidden-trouble.Therefore, be necessary to design a kind of AC power power failure alarm set.
Below describe in detail AC power power failure alarm set described in the utility model necessity involved in implementation process, guardian technique content.
Utility model content
Goal of the invention and beneficial effect: some electric equipment, needs automatically to remind in time, to inform that administrative staff get rid of line fault as early as possible when occurring therefore have a power failure in AC power.In the area often had a power failure, the thing not connecting electrical appliance power supply in time because of a variety of causes after power failure happens occasionally, after some equipment has a power failure, electrical appliance is provided with automatic closing function, need manual intervention just can recover normal work, as: poultry electricity incubation equipment, once have a power failure and can not be found in time, gently then cause poultry hatching to bring out rate and reduce, heavy then cause very large economic loss; For another example: the electrical heated appliances such as electric iron, once have a power failure restore electricity again after, be easy to bury disaster hidden-trouble.AC power power failure alarm set described in the utility model, is characterized in that cost of manufacture is low, easy to use, safe and reliable to operation.
Circuit working principle: AC power power failure alarm set is when AC power normal power supply, AC relay J normally-closed contact J-1 adhesive, thus the normally-closed contact J-1 of AC relay J is disconnected, at this moment AC power is charged to electrochemical capacitor C1 by indicator light HL, silicon rectifier diode D1.When AC power is because of fault outage, the dead electricity release immediately of AC relay J coil, its normally-closed contact J-1 closes at once, the electricity stored in electrochemical capacitor C1 is discharged to acoustic-optic reminding circuit, make that neon bulb NP is luminous, music buzzer HA sends prompting musical sound, musical sound reminder time is about 2min.
Technical scheme: AC power power failure alarm set, it comprises 220V AC power, halfwave rectifier charging circuit, AC relay contact change-over circuit, acoustic-optic reminding circuit, it is characterized in that:
Halfwave rectifier charging circuit: it is made up of indicator light HL, silicon rectifier diode D1, electrochemical capacitor C1,220V AC power live wire end L connects the positive pole of silicon rectifier diode D1 by indicator light HL, the negative pole of silicon rectifier diode D1 connects the positive pole of electrochemical capacitor C1, and the negative pole of electrochemical capacitor C1 meets 220V AC power zero line side N;
AC relay contact change-over circuit: AC relay J coil one termination 220V AC power live wire end L, another termination 220V AC power zero line side of AC relay J coil N, the moving contact of AC relay J normally-closed contact J-1 connects the positive pole of electrochemical capacitor C1, and the fixed contact of AC relay J normally-closed contact J-1 connects acoustic-optic reminding circuit;
Acoustic-optic reminding circuit: it is made up of dropping resistor R1, neon bulb NP and music buzzer HA, the fixed contact of AC relay J normally-closed contact J-1 connects one end of dropping resistor R1 and one end of music buzzer, the other end of dropping resistor R1 meets 220V AC power zero line side N by neon bulb NP, another termination 220V AC power zero line side N of music buzzer.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment circuit working schematic diagram that the utility model provides an AC power power failure alarm set; AC relay J normally-closed contact J-1 in accompanying drawing 1 is in closure state.
Embodiment
According to the AC power power failure alarm set circuit working schematic diagram shown in accompanying drawing 1 and accompanying drawing explanation, and according to annexation between components and parts in each several part circuit described in utility model content, and components and parts technical parameter described in execution mode requires and circuit production main points are carried out enforcement and can be realized the utility model, is further described correlation technique of the present utility model below in conjunction with embodiment.
The technical parameter of components and parts and selection requirement
AC relay J should use small-sized 220V AC relay, and the model selected is JQX-13F, and require that the impedance of AC relay coil is the bigger the better, AC relay J can select the product only having one group of normally-closed contact;
HL is indicator light, and optional voltage is the incandescent lamp of 220V, power 5W;
D1 is silicon rectifier diode, and the model selected is 1N4007;
C1 is electrochemical capacitor, selects capacity to be 220 μ F, and it is withstand voltage is 250V;
R1 is dropping resistor, and its resistance is 910K Ω, power is 1W;
HP is neon bulb, can make the neon bulb in electrician's voltage test pencil;
HA is music buzzer, and optional voltage is the music buzzer of 220V.
Circuit production main points and circuit debugging
Because the circuit structure of AC power power failure alarm set is fairly simple, comparison is easy, as long as the electronic devices and components performance generally selected is intact, and the components and parts annexation to specifications in accompanying drawing 1 is welded, physical connection line and welding quality are through carefully checking correctly, and circuit of the present utility model does not need to carry out any debugging and can normally work.
If desired extend the reminder time of musical sound, suitably can increase the capacity of electrochemical capacitor C1.
Points for attention
When meeting power failure alarm set alarm, line outage reason must be made clear, can process if outside line has a power failure; If internal wiring causes power failure, safety at power cut must be understood, as: certain accident causes power failure, or internal wiring needs maintenance and has a power failure, electricity consumer must correctly judge, be short-circuited after fault to power consumption equipment especially, under not clear failure condition, electricity consumer could blindly close a floodgate power transmission! Otherwise easily cause because of false judgment fault coverage expand or the accidents such as electric shock occur, must treat that line fault processes and deal with problems arising from an accident, can manual power transmission.
Circuit components layout of the present utility model, circuit structure design, its shape and size etc. of outward appearance are not all key technologies of the present utility model; neither the claimed technology contents of the utility model; because not affecting the utility model specific implementation process, therefore do not illustrate one by one in the description.
