Description
Technical field
The present invention relates to a kind of socket, particularly relate to a kind of anti-interference energy-saving socket.
Background technology
Along with electronic equipment, computer are widely available with household electrical appliance, power supply noise interference problem becomes increasingly conspicuous and forms one
The most serious public hazards, particularly transient noise interference, its rate of climb is fast, the persistent period is short, voltage amplitude amplitude high, to microcomputer
It is easily generated severe jamming with digital circuit.According to statistics, serious threat electrically, in the cause of electronic equipments safety reliably working, 88.5%
It is from the electromagnetic interference in power supply.Accordingly, it would be desirable to solve suppression power supply noise interference electronic equipment effectively, stop again simultaneously
Power supply noise enters the problem that AC network disturbs other electronic equipment.The interference sealed in from power supply electric line generally is referred to as going here and there mould
Interference or differential mode interference, the line voltage seriously overloading caused such as power supply source landing or instability fluctuated；Big inductive load
When switching on or off, the surge of produced induced potential invades；The waveform distortion of the power supply network caused during high-power silicon controlled rectifier work；Non-thread
The sinusoidal wave form distortion that property power factor load causes；Cross interference between supply frequency and drift and power transmission line together,
The intrusion etc. of lightning surge electric current.Owing to series mode interference is scurried into by power input line, typically should eliminate as far as possible or make it
It is minimized as much as possible.Common mode disturbances refers in electric power system and test system, because of forward and backward circuit network reference no
It is samely, between the two ground being spaced, there is potential difference, and this potential difference in constantly change at random, this
Changeable irregular potential change is by by the distribution capacity of circuit, distributed inductance, stray inductance, electrostatic coupling, electromagnetism sense
Should, the channel such as high frequency radiation interferes；Or the interference caused by a kind of loop current indefinitely is formed because ground connection is improper；
Also include that test system sensor mates random disturbances produced by improper (mismatch) etc. with test loop sending-end impedance.For
For home or office electrical appliance, the suppression object of its common mode disturbances is mainly from the common mold noise interference of electrical network, because common mode
Image will be impacted by noise jamming with sound system.The socket of the suppression electromagnetic interference that currently there are, it is possible to fall
Electromagnetic interference on low power line, but be only capable of suppressing differential mode interference, it is impossible to suppression common mode disturbances.
It addition, along with household electrical appliance, being widely used of office appliance, add people and break the most at any time when not making electrical appliance
The custom of electricity, causes because the electricity of electric appliance standby waste is surprising, and in China, such as coming off duty, it is bad to be not related to display and printer etc.
Consumption habit causes the waste electricity up to 1,200,000,000 degree every year because of electric appliance standby." 1 advocated for response International Energy Agency (IEA)
Watt plan " and Beijing " 12 " energy-saving and emission-reduction whole people's action plan in the call of " minimizing standby energy consumption " that proposes, need to carry
Rise the performance of common socket, common socket is carried out technological innovation, be suitable for the use demand of people's life, the most automatically close
Close the function of electrical equipment, solve the bad consumption habit of people, solve " unmanned plane ", the problem of " the most standby " from technological layer.
