Abstract

The invention discloses an intelligent energy-saving device, mainly consisting of a main circuit, a control circuit and control software. The main circuit comprises a magneto-electricity conversion unit and a harmonic suppression energy feedback unit connected in parallel; the control circuit comprises a signal detection unit and a CPU control unit, wherein the signal detection unit transmits bypass instructions to the CPU control unit which transmits node instructions to the magneto-electricity conversion unit and controls the harmonic suppression energy feedback unit. The intelligent energy-saving device further comprises an automatic bypass system comprising a contactor. The invention can restrict transient impact, treat harmonic pollution, stabilize voltage fluctuation and improve the power factor and power efficiency, thereby saving the power cost, improving the power quality, protecting the device safety and prolonging the service life of the device.

Description

technical field [0001] The invention relates to a power supply device, in particular to an intelligent power-saving device used in the power supply systems of industrial and commercial enterprises, institutional units, lighting, air conditioners, fans, elevators, sockets and production equipment. Background technique [0002] At present, my country's power grid generally has the problem of voltage instability. A large number of harmonics, transients, and surges have seriously polluted the power grid. In addition, most of the electrical equipment in our country generally has a rated power greater than the actual operating power, that is, "big horse-drawn carts" The situation has caused a large amount of widespread waste in the use of electric energy in our country. Therefore, my country's energy utilization efficiency is only about 30%, which is about 10 percentage points lower than that of developed countries, and the energy consumption of output value is more than two times ...
