Abstract

The invention discloses a variable-frequency power saver of a single-phase injection molding machine, belonging to the technical field of motor energy-saving control. The variable-frequency power saver comprises an injection molding machine operating parameter detection circuit (10), a single-phase rectification circuit (20), a charging circuit (30), a battery (40), a battery switch (50), a single-phase inverter (6), a capacitor (70), a control circuit (80) and a single-phase power contactor (90). When applied to an injection molding machine with an AC motor, the variable-frequency power saver can respectively realize two energy saving methods of speed regulation energy saving and power grid peak load shaving simultaneously, and the effect of saving 20-90% of power can be generally achieved. The variable-frequency power saver of the single-phase injection molding machine has the advantages of simple and convenient structure, visual metering, obvious power saving effect and broad application prospect in the energy saving aspect of the injection molding machine.

Description

technical field [0001] The invention relates to a frequency conversion power saver for a single-phase injection molding machine, which belongs to the technical field of motor energy-saving control, and in particular to an electric power control device that simultaneously realizes two energy-saving methods of speed regulation and energy saving and power grid peak-shaving and valley-filling. Suitable for injection molding machines 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 on injection molding machines. [0004] At present, there are many occasions where the single-phase AC motor injection molding machine has not adopted energy-saving technology for energy-saving transforma...
