Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Please refer to Fig. 1, a kind of lighting energy saving shunting device, comprising: power supply [1], controller [2], bypass driver element [3], relay [4], contactor [5], bypass contact [6], pressure regulation driving [7], transformer [8], pressure regulation unit [9], bypass instruction [10], interchange input [11], exchange output [12], exchange common port [13]; Controller [2] and bypass driver element [3], pressure regulation drive [7] to form and are electrically connected; Contactor [5] indicates [10] with relay [4], bypass contact [6], pressure regulation unit [9], bypass, exchange and input [11], exchange common port [13] and form and be electrically connected; Transformer [8] and bypass contact [6], pressure regulation unit [9], exchange and input [11], exchange and export [12] and form and be electrically connected; Pressure regulation unit [9] and contactor [5], bypass contact [6], pressure regulation drive [7], transformer [8] forms and is electrically connected.
Power supply [1] provides power supply for relevant control and drive circuit; The by-passing signal that controller [2] exports, to bypass driver element [3], drives relay [4], and then control contactor [5] action or release; Bypass contact [6] is the normally-closed contact of contactor [5]; The Regulation Control signal that controller [2] exports drives [7] to pressure regulation, drive one group of switching device in pressure regulation unit [9], control the different taps connecting transformer [8], thus the output voltage of the low pressure winding of adjustment transformer [8], and then the output voltage of adjustment power supply; Bypass instruction [10] is used to refer to the state of bypass.
Please further referring to Fig. 2, this is the Bypass Control of the lighting energy saving power supply for high-intensity gas discharge lamp.Controller [2] is MCT801D by control module M1(model) serve as; Pressure regulation drives [7] to be served as by M2 unit, provides the triggering signal of bidirectional thyristor V1 ~ V4; Bypass driver element [3] is made up of resistance R3, R4 and triode V5, one end of resistance R4 is connected with the PL pin of control module M1, the other end is connected with the base stage of triode V5 and one end of resistance R3, and the other end of resistance R3 is connected with the emitter of triode V5, and ground connection; The coil of relay K J1 is in parallel with diode D1, and the anode of diode D1 is connected with the collector electrode of triode V5, and the negative electrode of diode D1 is connected to direct voltage VCC; Normally opened contact KJ1-1 mono-end of relay K J1 is connected to one end of contactor, and the other end is connected to and exchanges common port N; Relay [4] is KJ1, and its contact is KJ1-1; Contactor [5] is KM1, and bypass contact [6] are in parallel by KM1-1, KM1-2 two groups of normally-closed contacts; Transformer [8] is T1, has multiple pressure regulation tap; Pressure regulation unit [9] is made up of switching device bidirectional thyristor V1 ~ V4; Lin exchanges input [11]; Lout exchanges to export [12]; Exchanging common port [13] is N; Bypass instruction [10] is made up of auxiliary normally-closed contact KM1-4, the resistance R5 of KM1, light-emitting diode D2.
Transformer T1, has multiple pressure regulation tap, and its low pressure windings in series is at interchange input Lin and exchange between output Lout.
Bypass contact [6] is normally-closed contact, in parallel by KM1-1, KM1-2 two groups of normally-closed contacts of contactor KM1, and is in parallel with pressure regulation unit [9] Zhong mono-road bidirectional thyristor element V4.Concrete method of attachment is: KM1-1, KM1-2 two groups of normally-closed contacts of contactor KM1 are in parallel, in parallel with piezo-resistance RV1 again, in parallel with the series arm of electric capacity C2 with resistance R2, the one end of the parallel connection unit formed is connected with the second plate of the 7th lead-out wire of transformer T1 and bidirectional thyristor V4, the other end with exchange common port N and be connected, the first anode of bidirectional thyristor V4 with exchange common port N and be connected.The effect of piezo-resistance RV1 is that the peak voltage on normally-closed contact and bidirectional thyristor V4 is carried out amplitude limit, the effect of the series arm of resistance R2 and electric capacity C2 absorbs the peak voltage on normally-closed contact and bidirectional thyristor V4, reduces dv/dt, di/dt value on bidirectional thyristor V4.
Operation principle is: the armature winding being added to transformer T1 from the alternating voltage of Lin input, when the PL pin of control module M1 exports high level signal, by resistance R3, R4 provides bias voltage to triode V5 base stage, triode V5 saturation conduction, relay K J1 coil energized action, contactor KM1 coil obtains voltage operation, bypass contact KM1-1, KM1-2 disconnects, the each tap of armature winding of transformer T1 controls by bidirectional thyristor V1 ~ V4, by the bidirectional thyristor of wherein conducting, corresponding for transformer tap is connected to interchange common port N, the voltage of transformer secondary output winding equals armature winding institute making alive divided by no-load voltage ratio, ac output voltage equals the voltage that AC-input voltage subtracts transformer secondary output winding, no-load voltage ratio is relevant with the tap joint position that thyristor is connected, so, ac output voltage obtains adjustment, the power consumption of high-intensity gas discharge lamp is relevant to added voltage, the brightness of adjustable high-intensity gas discharge lamp and fractional energy savings thus.M2 is the triggering signal driver element of bidirectional thyristor V1 ~ V4, and it receives the control signal from control module M1, realize electrical isolation, then the drive circuit in M2 triggers corresponding thyristor by the optocoupler in M2.
When the PL pin output low level signal of control module M1, triode V5 ends without bias voltage because of base stage, relay K J1 is failure to actuate, contactor KM1 coil is in reset mode because of no-voltage, bypass contact KM1-1, KM1-2 are closed, whole numbers of turn of the armature winding of transformer T1 are received interchange common port, and thus the output voltage of transformer secondary output winding is minimum, completes bypass functionality.Output voltage during bypass, a little less than line voltage, namely still has the energy-saving effect of low power saving rate under bypass condition, is applicable to the occasion that light fixture supply power voltage is normal or voltage is higher and uses.During bypass, the normally-closed contact KM1-4 of contactor KM1 closes, and the direct voltage VCC provided by power supply [1] is added on light-emitting diode D2 by contact KM1-4, resistance R5, and D2 is luminous, and instruction is in bypass condition.
In addition, the normally opened contact KM1-3 of contactor KM1 is used for providing bypass condition signal to control module M1.
Because the present invention carries out Bypass Control at the high-voltage side of transformer, thus control electric current less, the capacity of required electric component is little, with prior art switch compared with bypass at major loop, the volume of required bypass electric component is little, cost is low, reliability is high.
