Description
Technical Field
The utility model belongs to the technical field of power electronic equipment, especially, relate to a novel annular ferrite structure of reactor.
Background
The heavy use of modern power electronics generates non-linear currents, which generate harmonics that affect and aggravate grid pollution and cause severe interference to capacitors, transformers and transmission equipment. Resonance and voltage distortion can also cause power supply and utilization accidents, and the detuning reactor is used for improving and avoiding the harm of harmonic current. The detuning reactor is also called as a series reactor and is used for reactive power compensation, is generally used in series with a capacitor and is capacitive under power frequency, thereby preventing parallel resonance and non-amplified harmonic current, inhibiting higher harmonics, limiting switching-on inrush current, improving system power factor, preventing harmonic capacitors from causing harm, and avoiding excessive amplification and resonance of the capacitor device connected to the power grid harmonic.
The conventional detuning reactor adopts non-oriented silicon steel sheets and has the defects of easy overload, large volume, high temperature rise and the like.
