Abstract
A passive-type harmonic removal device, wherein the intensities of all the 2nd to 50th harmonics present in an electric line are simultaneously reduced through a material part which includes N (N>2) materials and is connected to the electric line in an electrically insulated state to receive and remove thermal energy of the electric line.
Claims14
A passive harmonic removal device, comprising:
- a material part connected to an electric line in an electrically insulated state and including N (N≥2) materials to which thermal energy of the electric line is conducted and which the thermal energy is removed, wherein the passive harmonic removal device is configured to simultaneously reduce intensities of all 2nd to 50th harmonics existing on the electric line through the material part,
- wherein the N materials include oxides having electrical insulation characteristics and thermal energy removal characteristics,
- wherein the oxides include 95 to 96 wt % of aluminum oxide;
- and 4 to 5 wt % of impurities consisting of P2O5, SO3 and K2O,
- wherein the material part has a compressive strength range of at least 85 kgf/cm2 or more,
- wherein the material part has an insulation resistance of 100 MΩ or more, and
- wherein the passive harmonic removal device reduces intensities of 2nd to 50th harmonics existing in the electric line connected to an electrode part by 65% or more.
