Title
(EN) ARC PATH GENERATION UNIT AND DIRECT CURRENT RELAY INCLUDING SAME

Abstract
(EN) Disclosed are an arc path generation unit and a direct current relay including same. An arc path generation unit according to various embodiments of the present invention comprises a Halbach array or a magnet part which forms a magnetic field in a space part for accommodating fixed contacts. The formed magnetic field forms an electromagnetic force, together with the current flowing a direct current relay. The formed electromagnetic force may induce generated arcs. The electromagnetic force formed near each fixed contact is formed in a direction going away from each fixed contact. Therefore, the generated arcs do not meet each other, and thus can be effectively suppressed and discharged.
(FR) La présente invention concerne une unité de génération de trajet d'arc et un relais à courant continu la comprenant. Une unité de génération de trajet d'arc selon divers modes de réalisation de la présente invention comprend un réseau de Halbach ou une partie d'aimant qui forme un champ magnétique dans une partie d'espace pour recevoir des contacts fixes. Le champ magnétique formé forme une force électromagnétique, conjointement avec le courant circulant dans un relais à courant continu. La force électromagnétique formée peut induire des arcs générés. La force électromagnétique formée à proximité de chaque contact fixe est formée dans une direction s'éloignant de chaque contact fixe. Par conséquent, les arcs générés ne se rencontrent pas mutuellement, et peuvent ainsi être efficacement éliminés et déchargés.
(KO) 아크 경로 형성부 및 이를 포함하는 직류 릴레이가 개시된다. 본 발명의 다양한 실시 예에 따른 아크 경로 형성부는 고정 접촉자가 수용되는 공간부에 자기장을 형성하는 할바흐 배열 또는 자석부를 포함한다. 형성된 자기장은 직류 릴레이에 통전되는 전류와 함께 전자기력을 형성한다. 형성된 전자기력은 발생된 아크를 유도할 수 있다. 이때, 각 고정 접촉자 부근에서 형성되는 전자기력은 각 고정 접촉자에서 멀어지는 방향으로 형성된다. 따라서, 발생된 아크가 서로 만나게 되지 않아, 효과적으로 소호 및 배출될 수 있다.
