Abstract

L'invention concerne un noyau magnétique de transformateur à stabilité, comprenant un corps de noyau magnétique (1); le corps de noyau magnétique comprend une base (2), un noyau magnétique en forme de U (3), et un noyau magnétique en forme de I (4); le noyau magnétique en forme de U et le noyau magnétique en forme de I sont respectivement montés aux deux extrémités de la base; une rainure (5) est formée sur une face d'extrémité du noyau magnétique en forme de I, une bobine (7) est enroulée sur le noyau magnétique en forme de U, un trou traversant (8) est formé sur le noyau magnétique en forme de U, et le trou traversant est disposé à l'opposé de la bobine; une feuille de cuivre (6) est disposée entre le noyau magnétique en forme de U et le noyau magnétique en forme de I, une fente (9) est formée sur la base, et la feuille de cuivre est montée dans la fente. Le noyau magnétique de transformateur est simple en termes de structure et de sécurité lors de l'utilisation, ce qui permet d'obtenir une caractéristique de courant élevé, une conductivité magnétique élevée, et une tolérance élevée à un changement de température; le noyau magnétique de transformateur est constitué de ferrite de telle sorte que l'effet de filtrage du noyau magnétique est bon, et deux colonnes magnétiques sont combinées de telle sorte qu'une ligne magnétique de force entre le transformateur et une bobine d'induction sont indépendantes l'une de l'autre dans le processus de travail ultérieur sans affecter l'autre, améliorant la stabilité de travail; le réglage du trou traversant améliore la sécurité du noyau magnétique; et la feuille de cuivre peut être détachée et montée pour répondre à différents besoins, et ainsi les fonctions sont diverses.
