Title
(EN) HARMONICS FILTERS USING SEMI NON-MAGNETIC BOBBINS
(FR) FILTRES D'HARMONQUES FAISANT INTERVENIR DES BOBINES SEMI-NON MAGNÉTIQUES
Abstract
(EN)
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 electrical power 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.

L'invention concerne des bobines semi-non magnétiques destinées à être utilisées dans des réacteurs à cœur, et des réacteurs à cœur qui comprennent les bobines semi-non magnétiques. Les bobines semi-non magnétiques sont constituées d'un matériau non métallique et fournissent des réacteurs à cœur qui peuvent résister à des températures élevées et éviter en même temps des effets de courant de Foucault. Les bobines semi-non métalliques perméables selon l'invention n'affectent pas non plus la qualité de puissance électrique et permettent d'économiser de l'énergie, et peuvent servir à capturer des courants d'harmoniques. Lorsqu'elles sont correctement conçues et disposées, les bobines peuvent servir à fournir une induction électromagnétique à des dispositifs de chauffage au moyen de courants d'harmoniques importés à partir d'un système d'alimentation électrique en tant que source de chaleur de travail et à fournir un processus de chauffage gratuit.
