Embodiment
Fig. 1 low-voltage lighting Variac type non-contact shift voltage-reduction power saver of the present invention, its structure is made up of variac and noncontacting switch voltage-regulation voltage-stabilization system.A ' N is an ac input end, and aN is an output, and K is a circuit breaker, and k5, k6 are two groups of inverse parallel controllable silicons, carries out interlocking control, the k5 conducting, and when k6 turn-offed, variac occurred with the automatic coupling voltage regulator form, and electricity-saving appliance is in pressure regulation step-down state; The k6 conducting, variac occurred with the transformer form when k5 turn-offed, and the output of electricity-saving appliance is input voltage, is in non-electricity-saving state.The automatic coupling voltage regulator coil is divided into AB, BC, and CD, DE, five sections of EF, the A end is input, the B point connects an end of load.C, D, E, F meet noncontacting switch k4, k3, k2, the k1 that one group of inverse parallel controllable silicon constitutes separately, and the other end of four noncontacting switches and the other end of load directly are connected on another input of power supply.
Suppose that line voltage just in time is 220V, the K closure, the k5 closure, under the k6 disconnection:
As k1 connection k2, k3, when k4 disconnected, the voltage of load was 205V;
As k2 connection k1, k3, when k4 disconnected, the voltage of load was 200V;
As k3 connection k1, k2, when k4 disconnected, the voltage of load was 195V;
As k4 connection k1, k2, when k3 disconnected, the voltage of load was 190V;
The K closure, k5 disconnects, and when k6 was closed, k6 was with the BF section short circuit of automatic coupling voltage regulator coil, and the aN terminal voltage equals the AN terminal voltage, is 220V.Electricity-saving appliance is in non-electricity-saving state.
Control circuit (1) comprises accessory power supply (2), control board (3), check-out console (4), control panel (5) and controllable silicon drive plate (6).Accessory power supply (2) is connected to the input supply terminal a ' N of electricity-saving appliance, is connected to control board (3) through level conversion and provides required power supply for it.Control board (3) is connected with check-out console (4), control panel (5) and controllable silicon drive plate (6), the signal that check-out console (4) detects back is input to control board (3), control board (3) receives the instruction (energy-conservation or non-energy-conservation, step-down grade) from control panel (5) simultaneously, handle through DSP, some groups of control signals of control board (3) output are passed through to be connected to after controllable silicon drive plate (6) driving is amplified again and are respectively organized between silicon controlled gate pole and the negative electrode.As the drive signal of inverse parallel controllable silicon k1, k2, k3, k4, k5, k6, Gx and Ex are connected respectively between silicon controlled gate pole and the negative electrode respectively for the signal that controllable silicon drive plate (6) sends (G1, E1), (G2, E2), (G3, E3), (G4, E4), (G5, E5), (G6, E6).
Under the control of control circuit, the present invention has the hand adjustment function, can and be stabilized in three pressure regulation shelves: 195V, 200V, 205V voltage control; And it also has the program control function, and as required, at different time points, the control lighting circuit has different voltage.
Variac of the present invention following characteristics are arranged:
1) the tie point B of variac and load fixes, and the other end of load directly is connected on the other end of power supply, and therefore, in the pressure regulation process, the phenomenon of " dodging disconnected " can not appear in load.
2) the electric current difference that each section coil flows through in the variac, except the AB section need adopt the heavy gauge wire coiling, other each sections can adopt the thin wire coiling, can dwindle the volume and the cost of automatic coupling voltage regulator like this.
The present invention still is a noncontacting switch automatic voltage regulation system.Because the mains supply change in voltage is bigger, can between 190V-250V, change, therefore, go up (for example being fixed on the 200V shelves) even the connection of noncontacting switch is fixed on a certain shelves, the automatic coupling voltage regulator output voltage can not be fixed on 200V yet, but changes along with the change of line voltage.Because the grid voltage change scope is bigger, no matter be connected on which shelves, output voltage all can have very big mobility scale.The phenomenon that will occur turning off the light when load voltage is too low; On the contrary, the too high effect that does not have economize on electricity again of load voltage, as seen, be not automatic coupling voltage regulator to be fixed on a certain shelves just can economize on electricity, but must pass through control circuit, at any time adjust the automatic coupling voltage regulator gear, the voltage control of exporting to load and be stabilized in the effect that really to play economize on electricity on the voltage of appointment.Noncontacting switch k1, k2, k3, k4 not only have the effect of pressure regulation, and and control circuit formation automatic voltage regulation system.Such as, allow lighting load work at 200V, then k3 connects, k1, k2, k4 disconnects.If this moment, line voltage was higher, load voltage can exceed 200V, and at this moment, control circuit can automatically shut down k3 after detecting the higher signal of line voltage, connects k4, and load voltage is descended; On the contrary, if the line voltage drop, load voltage can be lower than 200V, after then control circuit detects line voltage signal on the low side, can automatically shut down k3, connects k2, and load voltage is risen, thereby reaches the purpose of automatic stabilisation in 200V work.
The present invention has designed rational control circuit and control program, produces loop current when having avoided the voltage gearshift, and the exciting curent of switch switching moment appearance is controlled at minimum.
