Description
Technical field
The utility model belongs to electronic auto-control technology field, auto-breaking supply socket of sending a telegram here after relating to a kind of power failure.
Background technology
In the area often had a power failure, the thing of not closing electrical appliance power supply in time because of a variety of causes after power failure happens occasionally, once restore electricity, the electrical appliance of not closing just can be energized work voluntarily, light then waste electric energy, shorten useful life of electrical appliance, heavy then the likely security incident such as initiation fire, as: the various electrical heated appliance such as electric iron.If send a telegram here auto-breaking supply socket after using power failure described in the utility model, when then sending a telegram here after power failure, electrical appliance is in off-position all the time again, achieves auto-breaking in unattended operation situation, supply socket just must have voltage and export by human intervention, and electrical appliance could be energized work.
Below describe power failure described in the utility model in detail to send a telegram here afterwards the core technology content involved in implementation process of auto-breaking supply socket.
Utility model content
Goal of the invention and beneficial effect: in the area often had a power failure, the thing of not closing electrical appliance power supply in time because of a variety of causes after power failure happens occasionally, once restore electricity, the electrical appliance of not closing just can be energized work voluntarily, light then waste electric energy, shorten useful life of electrical appliance, heavy then the likely security incident such as initiation fire, as: the various electrical heated appliance such as electric iron.If send a telegram here auto-breaking supply socket after using power failure described in the utility model, when then sending a telegram here after power failure, electrical appliance is in off-position all the time again, achieves auto-breaking in unattended operation situation, supply socket just must have voltage and export by human intervention, and electrical appliance could be energized work.Feature of the present utility model is that circuit structure is succinct, cost of manufacture is low, easy for installation, safe and reliable to operation.
Circuit working principle: incoming call auto-breaking supply socket after having a power failure, 220V AC power supplies direct current relay J coil direct-current working volts after decompression capacitor C1 step-down, silicon rectifier diode D1 rectification, voltage stabilizing didoe DW voltage stabilizing.Attention: direct current relay J uses its normally opened contact J-1.When sending a telegram here, because normally opened contact J-1 disconnects, therefore direct current relay J coil is without direct-current working volts, therefore normally opened contact J-1 can not be made to close, therefore exports without electricity in supply socket CZ again; When needs power up to electrical appliance, only need press push-button switch AN, then direct current relay J coil obtains operating voltage, and normally opened contact J-1 is closed.After this, although push-button switch AN disconnects, the closed of normally opened contact J-1 can make direct current relay J self-locking.When having a power failure, normally opened contact J-1 disconnects; When sending a telegram here, circuit will repeat the above-mentioned course of work again.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment circuit working schematic diagram of incoming call auto-breaking supply socket after the utility model provides to have a power failure.
Embodiment
According to send a telegram here after the power failure shown in accompanying drawing 1 auto-breaking supply socket circuit working schematic diagram 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.
Technical characteristic: incoming call auto-breaking supply socket after having a power failure, it comprises 220V AC power, halfwave rectifier and filter circuit of pressure-stabilizing, startup and direct current relay latching circuit, supply socket current supply circuit, it is characterized in that:
Halfwave rectifier and filter circuit of pressure-stabilizing: it is by decompression capacitor C1, bleeder resistance R1, silicon rectifier diode D1, voltage stabilizing didoe DW and electrochemical capacitor C2 forms, the operating voltage that voltage stabilizing didoe DW uses is 24V, decompression capacitor C1 one end and bleeder resistance R1 mono-termination silicon rectifier diode D1 positive pole and voltage stabilizing didoe DW negative pole, silicon rectifier diode D1 negative pole connects electrochemical capacitor C2 positive pole, voltage stabilizing didoe DW positive pole and electrochemical capacitor C2 negative pole meet the zero line side N of 220V AC power, the decompression capacitor C1 other end and another termination of bleeder resistance R1 start and direct current relay latching circuit,
Direct current relay latching circuit: it is made up of direct current relay J and normally opened contact J-1 thereof, button switch AN, direct current relay J coil one termination silicon rectifier diode D1 positive pole, the zero line side N of another termination 220V AC power of direct current relay J coil, the decompression capacitor C1 other end and bleeder resistance R1 other end button switch AN one end and direct current relay J normally opened contact J-1 moving contact, the button switch AN other end and direct current relay J normally opened contact J-1 fixed contact meet the live wire end L of 220V AC power;
Supply socket current supply circuit: supply socket CZ mono-termination direct current relay J normally opened contact J-1 moving contact, the zero line side N of another termination 220V AC power of supply socket CZ.
The technical parameter of components and parts and selection requirement
D1 is silicon rectifier diode, and the model selected is 1N4007;
The operating voltage of voltage stabilizing didoe DW is 24V, and voltage stabilizing didoe power is 1W, chooses voltage stabilizing and is worth a little higher than direct current relay coil working voltage, to ensure that direct current relay J can reliably working;
Direct current relay J selects coil working voltage to be 24V, selects contact point mode to be often open, and the size of current of normally opened contact J-1 should be determined according to the power of electrical appliance;
The capacity of electric capacity C1 is 0.47 μ F, and its withstand voltage selects 630V;
C2 is electrochemical capacitor, selects capacity to be 470 μ F, and it is withstand voltage is 50V;
