Title
(EN) FUSE COMPRISING PERMANENT MAGNET FOR INDUCING ARC DIRECTIVITY
(FR) FUSIBLE COMPRENANT UN AIMANT PERMANENT POUR INDUIRE UNE DIRECTIVITÉ D'ARC

Abstract
(EN)
The purpose of the present invention is to increase the disconnection speed of an element (that is, decrease the blocking speed of a fault current) by arranging a magnet on the inner surface, the outer surface, or the inside of a porcelain tube included in a fuse and orienting, in a condensed manner, the traveling direction of arc energy into a constant direction according to Fleming's left-hand law by means of the magnetic field direction of the arranged magnet, thereby increasing the fault current blocking performance of the fuse. In particular, the present invention is characterized in that the location of the magnet arranged on the porcelain tube is arranged at the intermediate point between notching parts, a notching part point, or the porcelain tube corresponding to the intermediate point between notching parts and the notching part point.

Le but de la présente invention est d'augmenter la vitesse de déconnexion d'un élément (c'est-à-dire de diminuer la vitesse de blocage d'un courant de défaut) par agencement d'un aimant sur la surface interne, la surface externe, ou l'intérieur d'un tube en porcelaine compris dans un fusible et par orientation, de manière condensée, de la direction de déplacement de l'énergie d'arc dans une direction constante selon la règle de la main gauche de Fleming au moyen de la direction de champ magnétique de l'aimant agencé, ce qui permet d'augmenter la performance de blocage de courant de défaut du fusible. Plus particulierement, la présente invention est caractérisée en ce que l'emplacement de l'aimant disposé sur le tube en porcelaine est agencé au niveau du point intermédiaire entre des parties d'encochage, un point de partie d'encochage, ou le tube en porcelaine correspondant au point intermédiaire entre les parties d'encochage et le point de partie d'encochage.

본 발명은 퓨즈에 구성되는 애관의 내측면 또는 외측면 또는 내부에 자석을 배치하고, 배치된 자석의 자계방향에 의해 아크 에너지의 진행 방향이 플레밍의 왼손법칙에 따라 일정한 방향으로 응집적으로 향하도록 하여 엘레멘트의 단로 속도를 높여(즉, 사고전류의 차단속도를 감소시켜) 퓨즈의 사고전류 차단 성능을 높이고자 하는 발명에 관한 것이다. 특히, 애관에 배치되는 자석의 위치는 노칭부와 노칭부 사이 중간 지점, 노칭부 지점, 노칭부와 노칭부 사이 중간 지점과 노칭부 지점에 대응된 애관에 배치되는 것을 특징으로 하는 발명에 관한 것이다.
