Description of drawings
Below through accompanying drawing and specific embodiment the utility model is elaborated.
Fig. 1 is the schematic diagram of the power down switch that provides of the utility model;
Fig. 2 is the circuit diagram of Fig. 1.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the principle of the power down switch that the utility model provides, and for the ease of explanation, only shows the part relevant with the utility model, and the power down switch that the utility model provides can be contact switch or non-contact switch.
The power down switch that the utility model provides comprises: be connected in series in the switching circuit 12 in the mains-supplied loop with illuminating circuit; Illuminating circuit is luminous under the conducting state of switching circuit; And it is not luminous under the off state of switching circuit; In order to solve the purpose of prior art centrally connected power supply place waste electric energy; This power down switch that the utility model provides also comprises: two inputs are connected in parallel on the on-off control circuit 11 of illuminating circuit two ends, two outputs connection switching circuit 12; On-off control circuit 11 drives the switching circuit conducting under "on" position, on-off control circuit 11 drives switching circuit and turn-offs under off-position, thereby has cut off the supply access of civil power to luminescence unit.
In the centrally connected power supply place, use the power down switch that the utility model provides, can be implemented in stop centrally connected power supply after; Utilizing on-off control circuit 11 to drive switching circuit breaks off; After making that next centrally connected power supply begins, illuminating circuit can be not luminous automatically, saved electric energy; And when it is applied to dormitory, guaranteed people's rest.
It is example that Fig. 2 adopts single switch contacts S with switching circuit 12, shows the circuit of Fig. 1.
One end of switch S connects zero line, and the other end connects illuminating circuit.On-off control circuit 11 comprises that an input is connected in parallel on the rectification and the reduction voltage circuit 111 at illuminating circuit two ends; And being connected the output of rectification and reduction voltage circuit 111 and the electromagnet between the switch S, this electromagnet further comprises: be fixed in the armature (not shown) in the power down switch; Armature coil 112, its two ends connect two outputs of rectification and reduction voltage circuit 111 respectively; The iron core 113 hinged with switch S; And one end be fixed in the spring 114 that iron core 113, the other end contact with switch S.
When this power down switch was applied to the centrally connected power supply place, after beginning power supply, the user pressed switch S; Then illuminating circuit is luminous, and armature coil 112 energisings simultaneously make iron core 113 held by armature; At this moment, switch S receives the attraction of the elastic force and the iron core 113 of spring 114; Afterwards, when stopping power supply, armature coil 112 instant electricity loss, armature loses the attraction to iron core 113, and switch S automatic disconnection under the effect of the elastic force of spring 114 makes the current supply circuit of illuminating circuit be in off state.Then when beginning centrally connected power supply once more, illuminating circuit can be not luminous automatically, and after the user manually pressed switch S, illuminating circuit just can be luminous, thereby reached purpose of energy saving.And during whole power supply, the user can control illuminating circuit and stop luminous through the shutoff of control switch S.
Be example with certain school dormitory below, the energy-saving benefit of this power down switch that the utility model is provided is estimated:
The magnetic force F of electromagnet can be by formula: F=K*I
2Try to achieve, wherein, K is a constant, and I is the electric current that flows through armature coil 112; And constant K can be that the attraction experiment of the iron block of m obtains to a quality through this electromagnet, and the size that changes the electric current through armature coil 112 breaks away from electromagnet up to iron block, records the electric current I that flows through armature coil 112 this moment
0, then constant K can be by formula:
Try to achieve, suppose that the constant K of trying to achieve is 144N/A
2The maximum elastic force of supposing spring 114 is 0.8N, in order to increase the stability of power down switch work, supposes the big or small F=1N of electromagnet magnetic force, brings the magnetic force F and the constant K of trying to achieve into formula: F=K*I
2, can try to achieve current of electromagnet I is 0.0083A.The operating voltage of supposing electromagnet is 12V, then this moment electromagnet required power P=12*I=1W, the efficient of supposing rectification and reduction voltage circuit 111 is 80%, then the autophage power of this power down switch is 1.25W.
Be 5 years the useful life of supposing the power down switch that the utility model provides, and the bright lamp of each dormitory every day average time be 5 hours, the power consumption Q in this power down switch 5 years
05 hours/day * 1.25 watt-hour/skies=11.5 kilowatt hours of 365 days/year * of=5 years *.Suppose this power down switch than many 5 yuan of regular tap cost, being converted to electric weight is 10 kilowatt hours, then self the power consumption Q of this power down switch in its useful life
1-11.5 kilowatt hours+10 kilowatt hours=21.5 kilowatt hours.
According to statistics, each dormitory of this school uses two in 36W lamp source, and every day, each dormitory power-on time had more 1 hour, then the electric energy Q of each dormitory waste every day
22 * of=36 watts/individual *, 1 hour=0.072 kilowatt hour/sky that is to say, behind the power down switch that application the utility model provides, each dormitory can save energy 0.072 kilowatt every day, so but each dormitory saves energy Q in the 5 years useful life of this power down switch
3=0.072 kilowatt hour/365 days/year * 5 years=131.4 kilowatt hours of sky *, then clean saves energy is Q in each dormitory 5 years
4=131.4 kilowatt hours-21.5 kilowatt hour=109.9 kilowatt hours.
Suppose that this school has 1368 dormitories, then the clean saves energy of all dormitories is about in this school 5 years: Q
5=109.9 kilowatt hours/individual * 1368=150343.2 kilowatt hours.The student who considers some dormitory of back of stopping power supply evening is off switch initiatively, then supposes a correction factor, this correction factor value 0.7, and the clean saves energy of all dormitories is about in then revised this school 5 years: Q
Only=150343.2 kilowatt hour * 0.7=105240.24 kilowatt hours.
The utility model also provides a kind of on-off control circuit of aforesaid power down switch.
Use the power down switch that the utility model provides in the centrally connected power supply place; Can be implemented in stop centrally connected power supply after, utilize on-off control circuit 11 to drive switching circuits and break off, make that next centrally connected power supply begins after; Illuminating circuit can be not luminous automatically; Save electric energy, and when it is applied to dormitory, guaranteed people's rest.In addition, on-off control circuit 11 is simple in structure, and is with low cost, is easy to realize, on the basis that does not change existing regular tap, can realize purpose of energy saving, therefore, can realize the transformation to existing regular tap with less cost, but generalization is strong.
The above; Be merely the preferable embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and utility model design thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection range of the utility model.
