Besides, the streetlamp power saving device is low in cost and is optimum in cost performance as compared with the existing streetlamp power saving device in the prior art.
Description
Technical field
The utility model relates to a kind of circuit control device, is a kind of lighting saving device specifically.
Background technology
Be assurance street lamp ability operate as normal in peak times of power consumption, the output of street-lighting transformer generally will be transferred higherly (more than 230V).Because general street-lighting transformer does not possess real-time on-load voltage regulation function, as (after 23:00~0:00) after peak times of power consumption, supply power voltage will surpass the rated voltage of light fixture, generally reaches 240~250V, and is higher sometimes.This not only makes street lamp surpass rated power, a large amount of electric energy of waste, and shortened the useful life of street lamp, causes light fixture badly damaged.With the incandescent lamp is example, when supply voltage surpass its rated voltage 5% the time, its power surpasses rated power more than 10%, its life-span also can shorten half the.
The transitional street lamps battery saving arrangement can be divided into two types basically, and one type is to adopt fixedly step-down of delay timing control, and another kind of is by micro-processor controlled intelligent pressure regulating.Last class formation is simple, easy to maintenance, spend low; But the problem that exists is: 1. no matter whether voltage is too high, all regularly (like 23:00) control step-down.If this moment, voltage was not high, the brightness of step-down back light will be not enough, and this does not meet the requirement of national departments concerned to street lighting; If voltage is just too high before regularly, it is energy-conservation then can not to carry out step-down again; 2. underpressure is fixed, the employing heavy-duty diode half-wave step-down that has, voltage is reduced to about 120V, for incandescent lamp illumination reluctantly can, for mercury lamp, sodium vapor lamp just dying.The employing constant reactance device step-down that has can not well take into account the requirement of mercury lamp, sodium vapor lamp and incandescent lamp.The one type of battery saving arrangement in back has soft start-stop and real-time voltage regulation function by the system controlled by computer intelligent pressure regulating.Good energy-conserving effect can prolong useful life of light fixture, but that equipment is formed is complicated, and institute spend usefulness height (about 100,000 yuan), and maintenance difficulties is bigger.
The utility model content
To the problem of above-mentioned existence, the purpose of the utility model provides the high lighting saving device of a kind of cost performance.
The technical scheme of the utility model is: a kind of lighting saving device; Comprise step-down rectifying circuit, direct current regulation circuit, filtering shaping circuit, comparison control circuit, delay circuit, electronic switch, relay, contactor and do not have air gap reactor B; It is characterized in that: the output voltage step-down rectifying circuit of flowing through; Voltage gets into comparison control circuit through direct current regulation circuit and filtering shaping circuit respectively in the step-down rectifying circuit; Successively through delay circuit, electronic switch, relay and contactor output, no air gap reactor B seals in the circuit through main contact KM then.
The advantage of the utility model: this device utilizes electronic circuit to combine with relay, contactor, controls according to the size of actual motion voltage, and accomplishes that the step-down classification is adjustable, and practical, power savings is good.The actual motion statistics through many places, power saving rate is between 21-26%.Cost is lower, compares with present existing lighting saving device, and the ratio of performance to price is optimum.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Combine accompanying drawing at present, the utility model is further specified.
As shown in Figure 1, power supply is exported to the voltage of street lamp, after detecting transformer step-down and diode rectification, on the one hand through direct current regulation circuit, exports adjustable reference voltage U
g, on the other hand through filtering shaping circuit, the direct current detection voltage back U that output is directly proportional with the street lamp voltage swing
LWhen voltage just often, detected voltage U
LWith reference voltage U
gDifference very little, whole electronic circuit is failure to actuate, the normally closed main contact KM of contactor is closed, the power supply of the direct illumination light fixture of power supply.When overtension, detect voltage U
LWith reference voltage U
gCompare, its difference is bigger, makes comparison control circuit send control signal.Be the influence of avoiding voltage ripple of power network to cause, need through after the time-delay (about 30S) of certain hour that make the actuating of relay, contactor coil energising by electronic switch again, its contact KM opens, no air gap reactor B seals in and realizes step-down in the circuit.Change the tap position of B, can adjust the voltage of output, to adapt to different lightings.
Show that through practice the voltage control of incandescent lamp is at 180V~190V during step-down, the voltage control of mercury lamp and sodium vapor lamp effect when the 210V left and right sides is comparatively desirable.Reference voltage U in the circuit
gBe adjustable, this is in order to adapt to the step-down requirement of different lamps.Like the incandescent lamp street lamp, transfer U during corresponding voltage 180V~190V
g=U
L≈ 8V; For mercury lamp and sodium vapor lamp street lamp, transfer U during corresponding voltage 210V
g=U
L≈ 9V.
