Description
Technical field
The present invention relates to a kind of socket, relate in particular to a kind of anti-interference energy-saving socket.
Background technology
Along with extensively popularizing of electronic equipment, computer and household electrical appliance, power supply noise interference problem becomes increasingly conspicuous and forms a kind of very serious public hazards, particularly transient noise is disturbed, and its rate of climb is fast, the duration is short, voltage amplitude amplitude is high, and microcomputer and digital circuit are easily produced to severe jamming.According to statistics, serious threat is electric, in the cause of electronic equipments safety reliably working, and the 88.5%th, from the electromagnetic interference in power supply.Therefore, need to solve and effectively suppress power supply noise interference electronic equipment, stop again power supply noise to enter the problem that AC network is disturbed other electronic equipment simultaneously.Conventionally the interference sealing in from power supply electric line is called to series mode interference or differential mode interference, the caused line voltage landing of overload as serious in power supply source or fluctuated unstable; When large inductive load switches on or off, the surge of the induced potential that produces is invaded; The waveform distortion of the power supply network causing during high-power silicon controlled rectifier work; The sinusoidal waveform distortion that non-linear power factor loads causes; Between supply frequency and the drift of accompanying and power transmission line, intersect intrusion of interference, lightning surge electric current etc.Because series mode interference is scurried into by power input line, generally should eliminate as far as possible or make it to reduce to as much as possible minimum.Common mode disturbances refers in electric power system and test macro, because the reference ground of forward and backward circuit network is not same ground, between two ground, there is potential difference in this being spaced, and this potential difference in change at random constantly, and this changeable irregular potential change causes interference by channels such as the distributed capacitance by circuit, distributed inductance, stray inductance, electrostatic coupling, electromagnetic induction, high frequency radiations; Or because ground connection is improper, form the caused interference of a kind of loop current indefinitely; Also comprise that test macro transducer mates random disturbances that improper (mismatch) produce etc. with test loop sending-end impedance.For family expenses or office appliance, the inhibition object of its common mode disturbances is mainly the common mold noise interference from electrical network, because common mold noise interference will impact image and sound system.The socket of the inhibition electromagnetic interference existing in the market, can reduce the electromagnetic interference on power line, but only can suppress differential mode interference, cannot suppress common mode disturbances.
In addition, along with being widely used of household electrical appliance, office appliance, add people and when not making electrical appliance, there is no the custom of power-off at any time, cause the electric weight of wasting because of electric appliance standby surprising, in China, such as coming off duty, be not related to the bad consumption habits such as display and printer and cause waste electric weight because of electric appliance standby every year up to 1,200,000,000 degree.Call for " the minimizing standby energy consumption " that propose in response International Energy Agency (IEA) " the 1 watt of plan " advocated and the energy-saving and emission-reduction whole people of Beijing " 12 " action plan, need to promote the performance of common socket, common socket is carried out to technological innovation, more can adapt to the user demand of people's life, automatically close the function of electrical equipment in good time, solve people's bad consumption habit, from technological layer, solve the problem of " unmanned plane ", " long-time standby ".
