Description
Affiliated field
The utility model relates to a kind of supply socket of energy-saving safe.
Background technology
In the daily life, many electronic equipments that are used for family or public place use most remote controller that disposed for the convenience of the user.Electronic equipment though can quit work, does not disconnect power supply fully with electrical network and is connected after the shutdown that uses a teleswitch, and still is in holding state and continues to consume certain electric power.When restoring electricity after the unexpected power failure, some power consumption equipments can return to holding state even operating state once more because do not disconnect with electrical network physics, if people's this moment these power consumption equipments of real use not on the scene, so just cause meaningless electric energy loss, even cause and use electrification.The result of the statistics of authoritative department shows that the whole nation only just reaches 10,000,000,000 degree by the electric energy of the institute of the household electrical appliance under the holding state loss every year.Present existing common electrical force socket does not possess the function according to the operating state control on/off of each power consumption equipment on the socket, even there are some to aim at the energy-saving socket of certain specific electronic equipment set configuration, because of not possessing the unsuitable popularization and application of versatility, its energy-saving effect is also not satisfactory.
Goal of the invention
The purpose of this utility model is to overcome the existing deficiency of power receptacle aspect Energy Saving Control, provide a kind of and the total load current of receptacle loop is converted to detection voltage by instrument transformer, utilize the energy-saving safe socket of the corresponding control mains switch of the variation break-make that detects voltage, this socket can keep or close general supply automatically according to the state of power consumption equipment, after outage, can automatically lock, thereby realize energy-conservation and purpose that take precautions against natural calamities in closed condition.
The purpose of this utility model can realize by following technical scheme, a kind of energy-saving safe supply socket, comprise housing, housing is provided with some sockets in parallel, housing is provided with start button and threshold setting knob, circuit board is installed in the housing, circuit board is by instrument transformer, bridge rectifier filter circuit, the adjustable threshold circuit, delay circuit and power supply provide circuit to constitute, one end of the primary coil of instrument transformer connects a phase of AC power by start button, the other end is connected with one group of input terminal of socket, another of one group of outlet terminal of socket and AC power is connected, the secondary coil of instrument transformer is connected with bridge rectifier filter circuit, bridge rectifier filter circuit, the adjustable threshold circuit, delay circuit is connected successively, delay circuit connects relay and light-emitting diode display respectively, power supply provides circuit to be connected with delay circuit with the adjustable threshold circuit respectively, and the adjustable resistance of threshold setting knob is connected with the input circuit of adjustable threshold circuit.
Start button, instrument transformer and one group of socket in parallel constitute receptacle loop, the total load alternating current of receptacle loop is converted to exchange by instrument transformer and detects voltage, be converted to direct current detection voltage back by bridge rectifier filter circuit again, this direct current detection voltage back and preset gate are rationed the power supply and are compressed into row relatively, after the delay circuit time-delay, according to detecting voltage and the comparative result that presets threshold voltage, drive the on off operating mode of relay control general supply, this state is shown by light-emitting diode display.
The threshold setting knob is used to regulate threshold voltage, makes to preset threshold voltage just more than or equal to the voltage when all power consumption equipments are in holding state on the socket.When all power consumption equipments had been closed, detecting voltage will be less than presetting threshold voltage, and adjustable threshold ends, and after the time-delay, the relay power down disconnects, and general supply disconnects, and LED light is gone out; When power consumption equipment is worked, detect voltage greater than presetting threshold voltage, the adjustable threshold conducting, the relay adhesive, its control contact continues to connect, and general supply continues to open, and LED light is bright.
If recover incoming call after having a power failure again, because of start button has cut off electric power loop, control circuit has no way of obtaining working power, being connected in parallel on the other relay normally open contact of start button also can be not closed, therefore comprise that the whole electric power loop of the socket on the housing is in off-state, power down state is locked, and the power consumption equipment on arbitrary socket all can not get.
The power-frequency voltage of 220V becomes the direct voltage that the control circuit power supply is provided after power supply provides circuit step-down, rectifying and wave-filtering, voltage stabilizing.
The utility model has the advantages that to keep automatically according to the state of power consumption equipment or close general supply, after outage, can automatically lock, help improving the useful life of power consumption equipment, save user cost, the safety of protection people lives and properties in closed condition.
