Intelligent comprehensive power saver

Abstract

The invention discloses an intelligent comprehensive power saver. The intelligent comprehensive power saver comprises a switch control unit, a surge harmonic wave absorption unit, an input current sampling unit, an input voltage sampling unit, a data converter, a central controller, a keyboard display panel, a three-phase voltage acquisition control unit, an environmental monitoring unit, a compensation capacitor switchover unit, an output current sampling unit and an electric appliance, wherein the three-phase voltage acquisition control unit is connected with a group-A voltage regulator, a group-B voltage regulator and a group-C voltage regulator. The intelligent comprehensive power saver is capable of reducing the interference generated by a harmonic wave, keeping the harmonic wave of the electric appliance in a controllable range, automatically outputting a stable voltage value to protect the electric appliance from being burnt out, and prolonging the service life of the electric appliance.

Description

technical field [0001] The invention relates to an intelligent comprehensive power saver. Background technique [0002] In normal electricity consumption, the voltage of each place will have different differences, especially in summer, the electricity consumption in the south is more, while in winter the electricity consumption in the south is relatively small. Compared with the four seasons of the year, the difference is relatively large, and the north is always cold The power consumption is relatively stable, especially for air conditioners or other electrical appliances. Most of the voltages are below 220V, and the power supply is often higher than 220V during the transmission process. These voltages play a role in the rating of the electrical appliances. Not only can the normal use of electrical appliances be impossible, but also cause a large amount of waste of current, shorten the service life of electrical appliances, and there are harmonics in the circuit, which ...

Most of the voltages are below 220V, and the power supply is often higher than 220V during the transmission process. These voltages play a role in the rating of the electrical appliances. Not only can the normal use of electrical appliances be impossible, but also cause a large amount of waste of current, shorten the service life of electrical appliances, and there are harmonics in the circuit, which cause great interference to the power grid and electrical equipment, and seriously affect the normal use of electrical appliances. A large amount of electricity is wasted, how to deal with the problem of voltage regulation and harmonics is already a major problem in society
