Parallel Type Connected Device and Method for Absorbing Harmonic Current

摘要

The present invention relates to a parallel harmonic current absorption device. According to the present invention, the parallel harmonic current absorption device includes: an electrode unit including M conductive electrodes (M = 2) which are formed of a highly conductive metal material, electrically insulated from each other, and arranged to be separated by a predetermined interval or more in a preset arrangement relationship minimizing a polarization phenomenon; a power line unit electrically connected with each of M conductive electrodes and including M electric wires exposed to the outside; a ferroelectric mixture obtained by mixing N predefined materials (N = 2) including metal Si of 99% grade at a preset mixing ratio, grinding the mixture at a size of 10 μm or less and stirring the same to obtain mixed powder, oxidizing the mixed powder in a low temperature drying furnace of 80 °C to generate an oxide mixture, firing the same at a preset temperature in an electric furnace, cooling the fired mixture, mixing the same with a predefined binder according to a preset mixing ratio, liquefying the mixture, and drying the same at a room temperature in a state where the electrode unit is close to the liquefied mixture in a liquid state to be solidified; a lower case unit accommodating the ferroelectric mixture inside and maintaining an electrically insulated state from the electrode unit included in the ferroelectric mixture while exposing the electric wire unit to the outside; and an upper plate unit covering an upper part of the lower case unit and maintaining an electrically insulated state from the electrode unit included in the ferroelectric mixture. The present invention is able to extend a life span by reducing the number of failures of a load device.
