The energy-conservation circuit of the described single-phase autotransformer formula of Fig. 1 comprises autotransformer T, reversible electric machine M1, output feedback transformer T0 and voltage-stabilizing and energy-saving control circuit.Output feedback transformer T0 one tunnel provides 5V power supply for LM339 on the one hand through three-terminal voltage-stabilizing circuit LM7805 voltage stabilizing, and one side is the reference voltage of device as a comparison; Compare with reference voltage as the output voltage sampled signal behind over commutation in another road, when 5, the 4 pin voltages of IC1:A equated, output 2 pin were zero potential.Be lower than 5 pin voltages if output voltage reduction, the 4 pin current potentials of IC1:A drop to, 2 pin output potentials raise, the T1 conducting, and drive motors drives brush and slides to the direction of boosting; When 5,4 pin did not have potential difference, T1 turn-offed, and reversible electric machine stops operating; Otherwise, if output voltage raises, the 1 pin output high level of IC1:B, the T2 conducting, the driven by motor brush slides to the step-down direction, so just makes output voltage maintain stable startup set point, with energy-conservation set point.Whole energy-conservation process is in conjunction with Fig. 1, Fig. 4, and Fig. 5 describes
Behind closed mains switch ZK, driving switch is placed energy-conservation shelves, and (straight-through shelves are the fault shelves, both when the energy-saving appliance fault, beat straight-through shelves, the CN2 adhesive is directly powered by civil power), energization delay relay SJ2 this moment (time-delay in 5 seconds) and pipeline start up by preheating time relay sj 1 (different according to light fixture, warm-up time difference, operated by rotary motion was at 2～25 minutes) all not adhesives, at inner control circuit control in 5 seconds reversible electric machine voltage is adjusted to 220V starting resistor value.After 5 seconds, the SJ2 adhesive, its normally opened contact closure, energy-saving contactor CN1 gets electric adhesive, energy-saving electric power is with 220V voltage starting light fixture, when having reached pipeline start up by preheating that SJ1 sets after the time, the SJ1 adhesive, its normally opened contact closure, energy-conservation potentiometer W1 (Fig. 1) is dropped into control circuit, and the current potential that this moment, output voltage feedback signal c was ordered raises automatically because W1 is parallel to this sample circuit, and the 7 pin current potentials of IC1:B are higher than 6 pin current potentials, 1 pin output high level, the T2 conducting, drive motors rotates, and drives brush and slides to the step-down direction, regulate W1 output voltage a bit can be set arbitrarily at 180V～220V, to satisfy various energy-conservation needs.When the sliding point of energy-conservation potentiometer W1 was adjusted to the b point, c point current potential was the highest, makes output voltage minimum, reaches maximum power save mode.
The present invention considers because the illuminating line of various occasions can not adopt centralized control fully, in order to solve the problem of restarting after the partial illumination outage, so pipeline start up by preheating time relay sj 1 has the far-end reseting terminal, when needs actuating section lighting, can press reset button N simultaneously, SJ1 discharged also and picked up counting again this moment, the electric shock of often opening of SJ1 disconnects, c point current potential among Fig. 1 descends, output voltage is adjusted to once more the starting resistor of 220V, after the SJ1 adhesive, enter power save mode again.
