摘要： Disclosed are an arc path generation unit and a direct current relay including the same. An arc path generation unit according to various exemplary 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.

摘要： An arc path formation unit and a direct current relay including same are disclosed. The arc path formation unit according to various embodiments of the present invention comprises a Halbach array and a magnet unit, which form a magnetic field in a space part in which fixed contacts are accommodated. The formed magnetic field forms an electromagnetic force together with the current applied to the direct current relay. The formed electromagnetic force can induce generated arcs Here, the electromagnetic force formed in proximity to the respective fixed contacts is formed in the direction of moving away from the respective fixed contacts. Therefore, the generated arcs do not meet each other, and thus can be effectively extinguished and discharged.
