Abstract

Disclosed are semi non-magnetic bobbins for use in core reactors, and core reactors that include the semi non-magnetic bobbins. The semi non-magnetic bobbins are made of a non-metallic material and provide core reactors that can withstand high temperatures and at the same time avoid eddy current effects. The disclosed semi non-metallically permeable bobbins also do not adversely affect electricalpower quality and save power, and can be used to capture harmonics currents. When properly designed and arranged can be used to provide electromagnetic induction heaters using harmonics currents imported from an electrical power system as the working source of heat and provide a zero cost heating process.

Description

technical field [0001] The present disclosure relates to a half nonmagnetic bobbin used in a core reactor and a core reactor including the half nonmagnetic bobbin. More specifically, the present disclosure relates to semi-nonmagnetic bobbins used in core reactors capable of withstanding high temperatures while avoiding eddy current effects. These attributes result from the use of semi-non-metallic magnetically permeable spools that do not adversely affect power quality and save power. Background technique [0002] Power distribution systems supply power to linear and non-linear loads. Nonlinear loads generate current harmonic frequencies that saturate the distribution system. Typical machines that generate current harmonics are, for example, electronic switch-mode power supplies, battery chargers, adjustable speed motor drives (ASD), power rectifiers, uninterruptible power supplies (UPS), high-efficiency fluorescent lamps with electronic ballasts, and heating , ventilatio...
