Description

Environment-friendly type intelligent high-pressure sodium lamp energy-saving appliance
Technical field
The present invention relates to a kind of energy-saving appliance, particularly, relate to a kind of environment-friendly type intelligent high-pressure sodium lamp energy-saving appliance.
Background technology
Each big and medium-sized cities electricity consumption of China all exists tangible peak, paddy phase, and the change in voltage of electricity consumption peak phase and paddy phase is more outstanding again in the urban district.The resident falls sharply with the business electrical amount after 23 at dead of night, is tending towards the paddy phase, and electric current reduces relatively in this moment supply line, the line loss reduction, and voltage increases.For can exceeding 10-30 volt between 380 volts the general line of street lamp circuit, because the street lamp power consumption is directly proportional with voltage, so that the street lamp of working this moment all exceeds rated power is many.And street lamp mostly uses high-pressure sodium lamp and mercury lamp at present, its feature is that operating voltage slowly changed native 10% o'clock, and the well-illuminated variation of light is also not obvious, this just explanation, the merit that exceeds the part generation of street lamp rated voltage has mostly converted heat energy to, has only small part to convert luminous energy to.
In the prior art, traditional high-pressure sodium lamp electricity-saving appliance adopts fixedly these four kinds of modes of pressure regulating energy-saving device of self coupling buck zeroing control energy saver, controllable silicon chopper-type energy saving device for lighting, stepless power regulating formula pressure regulating energy-saving device or self coupling buck more.These four kinds of pressure regulating energy-saving device volumes are very large, and it is bigger to occupy environment space, and it is attractive in appearance also to influence the appearance of the city, makes troubles to installation; And its power saving rate can only be between 10% to 20%, and sodium vapor lamp and related accessories thereof are had very big influence useful life, the energy-conservation head and shoulders above value of maintenance cost, power saving but uneconomical.
For example energy saver is controlled in the zeroing of self coupling buck, and it regulates no-load voltage ratio by regulating transformer secondary zero line joint, thereby adjusts output voltage, but it causes the damage of other electrical accessorie easily in the rising of pressure regulation transient voltage.
Controllable silicon chopper-type energy saving device for lighting for example again, it adopts controllable silicon copped wave principle, by the angle of flow of control thyristor, the sine voltage of electrical network input is cut away a part, thereby reduced average value of output voltage, reaches the purpose of pressure control economize on electricity.But this voltage regulating mode makes voltage can't realize sinewave output owing to there is copped wave, also a large amount of harmonic waves can occur, and circuit, electrical network and power consumption equipment are all brought adverse effect, the adjacent communication circuit is disturbed big; And the device oneself power consumption is big, and it is relatively poor that power device bears the over-voltage and over-current ability, very easily damages, and can not use in capacitor compensating circuit.
Stepless power regulating formula pressure regulating energy-saving device for example again, it can regulate output voltage continuously by regulating the carbon brush position, and the voltage continuously smooth is adjustable, reaches the pressure regulating energy-saving purpose.But its volume is big, heavy, is not easy to the three-phase independent regulation; And have mechanical wear (for example carbon brush and transmission mechanism etc.), stuck phenomenon can appear in carbon brush after the fault that is short-circuited, and useful life is short, safeguards and the maintenance cost height.
The fixing pressure regulating energy-saving device of self coupling buck for example again, it is by an autotransformer movement, according to input voltage height situation, different in succession stationary transformer taps, the regulation and control voltage of setting according to certain time period carries out the work conversion, line voltage is reduced to the shelves that set, thereby reaches the purpose of voltage-reducing and electricity-saving.But adopt contactor when it switches mostly, there is outage the centre, and it is disconnected to cause light to dodge, and can not follow the variation of electrical network and dynamically adjusts output voltage; And pressure drop is fixed, and to light fixture unprotect function, can occur flash of light or light-off phenomenon during voltage ripple of power network, the useful life of having reduced light fixture.

For example Chinese patent application number has disclosed a kind of such structure for " the voltage-controlled light adjusting circuit and the method for work thereof of electronic ballast of high voltage sodium lamp " of CN200710019586.6 again: a kind of voltage-controlled light adjusting circuit of electronic ballast of high voltage sodium lamp, and it comprises comparison circuit, the trigger that is used to receive voltage control signal and is used for linking to each other to control the switching circuit of electronic ballast of high voltage sodium lamp power output with the power control input end of electronic ballast of high voltage sodium lamp; The output of comparison circuit connects the triggering signal input of trigger; The switch control input end of the triggering signal output termination switching circuit of trigger.This electronic ballast of high voltage sodium lamp only can require the low period to adjust the high-pressure sodium lamp power output at illuminating effect, and can not regulate the input voltage of sodium vapor lamp automatically according to the variation of line voltage, the intelligent degree of work is lower, can not adjust according to the virtual voltage situation on one's own initiative, reach the purpose of power and energy saving.
In sum, existing safe panel also can be further improved.

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing:
Embodiment: to shown in Figure 2, the environment-friendly type intelligent high-pressure sodium lamp energy-saving appliance in the present embodiment carries out work by connecting external power source (utility grid) and high-pressure sodium lamp as Fig. 1, and it comprises voltage processing unit 1, detection control apparatus 2 and changes pressure device 3.
Voltage processing unit 1 comprises transformation rectification circuit 11 and filter regulator circuit 12.
Transformation rectification circuit 11 comprises transformation rectification circuit input end and transformation rectification circuit output end, the transformation rectification circuit input end connects external power source, transformation rectification circuit 11 is exported by the transformation rectification circuit output end after according to the detected voltage range of detection control apparatus 2 external power source being carried out step-down rectifier.
Filter regulator circuit 12 comprises filter regulator circuit input and filter regulator circuit output, the filter regulator circuit input connects the transformation rectification circuit output end, after the electric current that filter regulator circuit 12 is imported the transformation rectification circuit input end according to the operating voltage of detection control apparatus 2 carries out filtering voltage regulation, by the filter regulator circuit output to detection control apparatus 2 output, thereby as the operating voltage of detection control apparatus 2.
Detection control apparatus 2 comprises that single-chip microcomputer, test side reach at least two signal end.The operating voltage of single-chip microcomputer is by connecting the input of filter regulator circuit output.The test side connects the transformation rectification circuit output end, and detection control apparatus 2 converts the current signal of test side input digital signal to and judges its size, and selects corresponding signal end output start signal according to judged result.This selection mode be when the voltage of judgment result displays external power source hour, select the little switching circuit of conducting step-down amplitude, and when the power supply of external power source is big, select the big switching circuit of conducting step-down amplitude, thereby the voltage that guarantees the high-pressure sodium lamp input can be not excessive, its specific implementation and circuit connect and will set forth hereinafter, do not repeat them here.
Change pressure device 3 and comprise that inductance element reaches at least two switching circuit, inductance element comprises that the inductance element input reaches at least two inductance element output, the quantity of switching circuit and inductance element output is consistent with the signal end of detection control apparatus 2, the inductance element input connects external power source, the inductance element output connects an end of corresponding switching circuit, the other end of each switching circuit all connects high-pressure sodium lamp, and each switch element also comprises the control end that connects respective detection control device 2 signal ends.When signal end continues the output start signal, corresponding switching circuit keeps conducting, different inductance element outputs is different with inductance value between the inductance element input, make each inductance element different with the inductance value that external power source, high-pressure sodium lamp and switching circuit form in the loop, the voltage of the external power source during this inductance value basis switching circuit conducting is accordingly determined with respect to the magnitude of voltage of the required step-down of normal working voltage of sodium vapor lamp.For example when the voltage of external power source was excessive, the step-down amplitude of required corresponding circuit was big, so the inductance value of the inductance element in the loop is bigger; And when the voltage of external power source hour, the step-down amplitude of required corresponding circuit is little, so the inductance value of the inductance element in the loop is less.
Operation principle of the present invention as shown in Figure 1, after the 11 transformation rectifications of outer power voltage process transformation rectification circuit, and detect by detection control apparatus 2, to judge the magnitude of voltage of external voltage this moment, and according to judged result to changing pressure device 3 output signals, open the switching circuit in a certain loop, because the inductance value difference of different circuit, antihypertensive effect difference to external voltage, the specific loop of selection conducting can make outer power voltage drop to suitable magnitude of voltage and export to high-pressure sodium lamp, make when outer power voltage is too high, still can keep the input voltage of high-pressure sodium lamp to be the required operating voltage of its operate as normal.
Circuit connecting mode of the present invention changes in the loop that pressure device 3 is arranged at external power source U and high-pressure sodium lamp D as shown in Figure 2.Change pressure device 3 and comprise the first switching circuit K1, second switch circuit K2, the 3rd switching circuit K3 and the 4th switching circuit K4, and inductance component L comprises the corresponding first, second, third and the 4th these four inductance element outputs, each switching circuit is provided with the relay switch of normal off, the signal end of the control end joint detection control device 2 of relay switch, when the signal end of detection control apparatus 2 is exported start signal, the relay switch closure.Particularly, pin PB1, the 3rd switching circuit K3 of pin PB0, the second switch circuit K2 connection single-chip microcomputer I1 of first switching circuit K1 connection single-chip microcomputer I1 connect the pin PB2 of single-chip microcomputer I1 and the pin PB3 that the 4th switching circuit K4 connects single-chip microcomputer I1.Each switching circuit is made up of diode, triode, resistance and relay switch, and its concrete mode can be carried out with reference to accompanying drawing 2 and prior art, does not repeat them here.
Inductance value between the first, second, third and the 4th inductance element output and the inductance element input increases successively, when external power source U voltage increased to certain particular range, the pairing signal end of inductance element output that the inductance value between corresponding and the inductance element input is bigger continued to export the corresponding switching circuit of start signal conducting.Because relay switch is a normal off, when the signal end of detection control apparatus 2 stopped to export start signal, relay switch disconnected, and is conducting so can the power circuit of a switching circuit only be arranged all the time, guaranteed that high-pressure sodium lamp D all the time can operate as normal.Like this, detection control apparatus 2 can change four kinds of inductance values of pressure device 3 outputs according to the size control of external voltage and seal in the sodium vapor lamp loop, the high more inductance value that seals in of external power source U voltage is big more, and the pressure drop on the inductance component L is big more, makes the voltage at sodium vapor lamp D two ends keep constant substantially.
Because when external power source U brownout, when the operating voltage of high-pressure sodium lamp D was higher than external voltage, the voltage of external power source U did not need step-down.So it is zero that the present invention's design makes the inductance value of winning between inductance element output and the inductance element input, promptly directly carries out short circuit.When external power source U voltage is lower than the normal working voltage of sodium vapor lamp D, the corresponding switching circuit of the signal end of the corresponding detection control apparatus 2 of first inductance element output output start signal conducting; When external power source U voltage increases above normal working voltage gradually, and the bigger pairing signal end of other inductance element outputs of the inductance value between the inductance element input is exported the corresponding switching circuit of start signal conducting more successively.Promptly when the voltage of detected utility grid the time less than certain value, the output start signal of detection control apparatus 2, the relay switch of Closing Switch circuit K1, thus will change pressure device 3 short circuits, make the voltage at sodium vapor lamp D two ends be unlikely to low, guarantee the operate as normal of sodium vapor lamp; And when external power source U voltage the time greater than predetermined value, the output start signal of detection control apparatus 2, the relay switch of Closing Switch circuit K2 (supposing that this moment, external power source U voltage was slightly larger than predetermined value), the sealing in the loop of a part of inductance of the inductance component L of pressure device 3 will be changed, reduced and received the input voltage at lamp D two ends, thereby reduced the power consumption of sodium vapor lamp D, because the inductance element that seals in consumed power not itself, thereby realized the purpose of power and energy saving.
For example, when outer power voltage is not more than 220V, actuating switch circuit K1, the inductance value of the inductance component L in the loop is 0 at this moment; When outer power voltage is not more than 225 greater than 220V, the switching circuit K2 that the inductance value of the inductance component L in the conducting loop is bigger than switching circuit K1; When outer power voltage is not more than 235 greater than 225V, the switching circuit K3 that the inductance value of the inductance component L in the conducting conducting loop is bigger than switching circuit K2; When outer power voltage is not more than 245 greater than 235V, the switching circuit K4 that the inductance value of the inductance component L in the conducting conducting loop is bigger than switching circuit K3.
Detection control apparatus 2 comprises TINY20PU single-chip microcomputer I1, external power source U voltage is by being input to the pin PB4 of TINY20PU single-chip microcomputer I1 in the mode of direct current signal after the transformation rectifying device step-down rectifier, because the pin PB4 of TINY20PU single-chip microcomputer I1 has A/D (digital signal/analog signal) translation function, by becoming digital signal to judge the size of external power source U voltage, go to control the output of changing pressure device 3 to the DC simulation conversion of signals of input according to resulting external power source U voltage swing.The operating voltage of described TINY20PU single-chip microcomputer I1 is imported by pin VCC, pin GND ground connection, and its pin connects and program editing can carry out with reference to accompanying drawing 2 and prior art, does not repeat them here.
Transformation rectification circuit 11 comprises power transformer T and bridge rectifier B, and external power source U is realizing rectification by after connecting power transformer T transformation by connecting bridge rectifier B.
The filtering voltage regulation device adopts fixed three terminal regulator LM7805 chip I 2, and fixed three terminal regulator LM7805 chip I 2 can provide the output voltage of various fixed, and applied range includes overcurrent, overheated and overload protecting circuit.During the band fin, output current can reach 1A, and output voltage can reach 5V, and input voltage can reach 35V, and output voltage is at 5~18V.Filter regulator circuit 12 physical circuits are formed as shown in Figure 2, wherein are parallel with electrochemical capacitor C1, C3 at fixed three terminal regulator LM7805 chip I 2 two ends, thereby play the effect of filtering.In addition, also be parallel with capacitor C 2, C4 at fixed three terminal regulator LM7805 chip I 2 two ends, thereby play the effect that prevents 2 self-excitations of fixed three terminal regulator LM7805 chip I.The concrete pin of fixed three terminal regulator LM7805 chip I 2 connects and can carry out with reference to accompanying drawing 2 and prior art, does not repeat them here.The 220V electric main is transformed into AC low-tension by power transformer T; pass through rectification and the filtering of bridge rectifier B and filter capacitor C1, C3 again; form at fixed three terminal regulator LM7805 chip I 2 two ends one not very galvanic current press, this voltage is usually can be because of the fluctuation of line voltage or the variation of load etc. former thereby change.This direct voltage has just produced precision height, VD that stability is good at output through the filtering of the voltage stabilizing of LM7805 and capacitor C 3.
