Description
Technical field
The invention 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 of the present invention, 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 of the present invention in detail to send a telegram here afterwards the core technology content involved in implementation process of auto-breaking supply socket.
Summary of the invention
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 of the present invention, 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 invention 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 that the invention provides the rear incoming call auto-breaking supply socket that has 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 summary of the invention, 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 present invention, is further described correlation technique of the present invention 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:
