Description

Micro power consumption power saving electronic adjuster

A kind of AC power input is transformed to the power supply control of AC power output or regulates conversion equipment, particularly a kind of little power consumption energy-saving electric adjuster.

At present mostly be the reactance speed regulator in the fan governor, the speed governing of this reactance speed regulator is discontinuous, and starting performance is poor at a slow speed, self power consumption is big, and be the contact switch speed governing, is easy to damage, and copper and silicon steel sheet consumption are big during manufacturing, the cost height, and volume is bigger.In addition, the condenser type energy-saving speed regulating device that also useful a plurality of electric capacity are formed, their volume, cost and energy consumption are all superior than the former, but still are that volume is bigger, and cost is higher, and speed governing is discontinuous, is the contact switch speed governing, is easy to damage.Only adopt the electronic controller of single loop RC phase-shift trigger circuit for some, its adjustable range is wide inadequately, and its least residue voltage reaches 30 volts, and the The initial segment neutral gear is big, instability.Six positions described phase-shift voltage regulating circuit part of ten function electronic power devices of selling on Chinese market is undesirable, internal power consumption big (about 5 watts), and temperature rise only is fit to short time work, and particularly not establishing the RC absorption circuit at BCR two ends is danger close.All there is common drawback in above-mentioned all situations, is exactly the indicating operating status imperfection.

The utility model provides a kind of that be made up of electronic component, internal power consumption can be low, adjustable range is wide, versatile demonstration and volume are little, and price little power consumption low, easy to use can the energy-saving electric adjuster.

The utility model is realized with following mode: this adjuster electronic circuit is made up of anti-clutter circuit, widening circuit, phase-shift trigger circuit and display circuit.Widening circuit is by resistance R ₁, capacitor C ₂Form capacitor C with adjustable resistance VR ₂It is 0.047 microfarad.Display circuit is composed in series by resistance and neon lamp.

Below in conjunction with accompanying drawing the utility model is described in further detail.

By inductance L and capacitor C ₁Form anti-clutter circuit (1), by resistance R ₁, capacitor C ₂Form widening circuit (2) with adjustable resistance VR, by potentiometer W, resistance B ₂, capacitor C ₃, diac DIAC, bidirectional triode thyristor BCR, resistance R ₃And capacitor C ₄Form phase-shift trigger circuit (3), by resistance R ₄Form display circuit with neon lamp ZD.Little power consumption energy-saving electric adjuster is to adopt electronic circuit to change the angle of flow of bidirectional triode thyristor, thereby makes controlled electric equipment terminal voltage be able to regulate in very wide scope.

Power supply is through potentiometer W, resistance R ₂To capacitor C ₃Capacitor C is worked as in charging ₃When the two ends charging voltage reaches the breakover voltage of bidirectional trigger diode DIAC, form a trigger impulse, make bidirectional triode thyristor BCR conducting, change potentiometer W value, i.e. scalable R ₂C ₃Time constant realizes the phase shift of trigger impulse, reaches to regulate output voltage average value this purpose.The phase shift range of general single time constant RC circuit is wide inadequately, and lower limit The initial segment instability, can only be used as on the equipment such as less demanding light modulation, temperature adjustment, and to the speed governing of electric fan, requirement is to accomplish from 0 to 100% adjusting as much as possible.For this reason, necessary broadening phase shift range, this adjuster adopt the dual-time constant circuit to form, i.e. potentiometer W, the resistance R of being used by phase shift ₂, capacitor C ₃The resistance R that circuit and broadening are used ₁, capacitor C ₁, the widening circuit formed of adjustable resistance VR constitutes.Resistance R ₃With capacitor C ₄Form the surge absorption circuit, in order to protection bidirectional triode thyristor BCR.Inductance L and capacitor C ₁Form low pass filter, prevent that the resonance wave that produces when bidirectional triode thyristor BCR conducting angle is less from producing dry acoustic jamming to other electrical equipment.By resistance R ₄Form display circuit with neon lamp ZD.Reaching the adjusting purpose by adjusting potentiometer W when this adjuster uses, is a kind of continuous contactless regulative mode.

This adjuster is owing to adopt the dual-time constant circuit and to the optimum organization of component parameters in the circuit, and range of regulation the sixth of the twelve Earthly Branches of adjuster can steadily adjusting in 0 to 98% zone of supply voltage.This circuit consumes energy about 0.18 watt, is far smaller than the about 1 watt level of domestic and international RC circuit wasted work rate.Because display circuit is selected neon lamp ZD for use, about 0.013 watt of the power consumption of a neon lamp, than a commonly used light-emitting diode institute wasted work rate about 0.7 watt much smaller.Because the circuit power consumption is very low,, can think that temperature remained on about ambient temperature when adjuster used so the heating of whole adjuster is little.Neon lamp ZD demonstration effect in the display circuit has: (1) does the power supply indication when the external power normal power supply; (2) owing to be connected in parallel on bidirectional triode thyristor BCR two ends, when the angle of flow hour, bidirectional triode thyristor BCR terminal voltage height, the neon lamp light intensity, and the angle of flow when big bidirectional triode thyristor BCR terminal voltage little, a little less than neon lamp is luminous, neon lamp extinguishes during full conducting, therefore can make output voltage and show; (3) as seen, in whole electronic circuit, as long as place open circuit, neon lamp extinguishes, so neon lamp has the detection effect of loop break-make concurrently from circuit; (4) night indoor pitch-dark, the salmon pink light that neon lamp is soft can clearly demonstrate the position of switch, and is easy to operate to the user.

This adjuster has the characteristics of little power consumption, low-temperature-rise, wide-voltage-regulation scope, anti-tampering, surge absoption, power supply indication, loop detection etc., can move steadily in the long term so can guarantee it. The advantages such as it has also that volume is little, in light weight, cost is low, easy to manufacture, easy to use, dependable performance, highly versatile, contactless adjusting, long service life, be applicable to the rotational speed regulation of electric fan, the incandescent lamp light modulation, the electric blanket temperature adjustment, the speed governing of dust catcher and domestic stirrer, and be used for the electric iron temperature adjustment after increasing the bidirectional triode thyristor area of dissipation.
