Abstract

The invention discloses a variable-frequency power saver of a single-phase air compressor, belonging to the technical field of energy-saving control of a motor. The variable-frequency power saver of the single-phase air compressor comprises an air compressor operation parameter detecting circuit (10), a single-phase rectifying circuit (20), a charging circuit (30), a battery (40), a battery switch (50), a single-phase inverter (60), a capacitor (70), a control circuit (80) and a single-phase power source contactor (90). When the variable-frequency power saver of the single-phase air compressor is applied to the air compressor of an alternating current motor, two energy-saving methods of speed regulation energy conservation and electric grid peak-reducing valley-filling can be respectively realized at the same time, and the energy can be saved by 20 percent to 90 percent. The variable-frequency power saver of the single-phase air compressor has the advantages of simple and convenient structure, intuitionistic metering and obvious power-saving effect, and has wide application prospect on energy-saving of the air compressor.

Description

technical field [0001] The invention relates to a frequency conversion power saver for a single-phase air compressor, which belongs to the technical field of motor energy-saving control, and in particular to an electric power control device for simultaneously realizing two energy-saving methods of speed regulation and energy saving and power grid peak-shaving and valley-filling. Suitable for air compressors with single-phase AC motors. Background technique [0002] With the progress of society and the development of science and technology, the global energy is becoming increasingly tense in the 21st century, and China is a big energy consumer, so energy saving is imperative. [0003] Therefore, it is necessary to carry out energy-saving transformation of air compressors. [0004] At present, there are many occasions where single-phase AC motor air compressors have not adopted energy-saving technology for energy-saving transformation, or simply installed frequency converters...
