Description

(1) Technical field [0001] The invention relates to a single-phase and three-phase AC precision full-automatic voltage stabilization intelligent microcomputer-controlled electric saver, which belongs to the comprehensive field of electronic intelligent control high-precision full-automatic voltage stabilization and period-by-time control. (2) Background technology [0002] At present, no matter at home or abroad, the power grid setting parameter program generally has a voltage of 240-250 volts (street lamps), and the work process must be started with high voltage and strong current (large load, long line), so that the voltage and current of the start-up circuit are low. The higher is larger, so that the end of the line can reach the rated voltage. As a result, many power equipments are overvoltage, which not only wastes electric energy, but also has a negative impact on the service life of equipment such as line lamps and lanterns. (1) (Taking incandescent lamps as an examp...

AI Technical Summary

Problems solved by technology

As a result, many electrical equipment overvoltage work, not only wasting electric energy but also negatively affecting the service life of line lamps and other equipment

(1) (Taking incandescent lamps as an example) when the operating voltage is 5% higher than the rated voltage, the life is shortened to 50%, and when the voltage is 10% higher than the rated voltage, the life is only 28% of the average life of the rated voltage

[0003] (2) If the grid voltage is too high, it will cause the load device to overheat, the heat energy will be released slowly, the actual power will not match, and the ratio will not be proportional, which will shorten the service life of the bulb and ballast

[0004] (3) The power grid voltage is too high, the voltage fluctuation range is large, transient surges, harmonics, etc., and have impact on electrical equipment, which not only affects the lighting quality and voltage stability of the motor, but also accelerates the aging of the equipment

[0005] (4) Due to insufficient power, virtual work caused by phase difference is common, the power factor is low, and the deviation of useful work is large, which increases the loss of equipment and power supply lines
