  • ARC PATH FORMATION UNIT AND DIRECT CURRENT RELAY INCLUDING SAME
    Publication number: 20230298839
    Abstract: An arc path formation unit and a direct current relay are disclosed. The arc path formation unit, according to various embodiments of the present disclosure, includes a Halbach array provided in at least one of the forward and backward directions. The Halbach array forms a magnetic field within an arc chamber by itself or along with another magnetic body. An electromagnetic force may be generated for inducing an arc that is generated by a formed magnetic field and current flowing through the direct current relay. The electromagnetic force is generated in a direction away from each fixed contact. Accordingly, the generated arc can be extinguished and discharged effectively.

  • ARC PATH-FORMING PART AND DIRECT CURRENT RELAY COMPRISING SAME
    Publication number: 20230290599
    Abstract: An arc path-forming part and a DC relay comprising same are disclosed. The arc path-forming part according to various embodiments of the present disclosure comprises a Halbach array and a magnet part that form a magnetic field in a space formed therein. The magnetic field formed by the Halbach array is stronger in the direction toward the space. The magnetic field formed by the Halbach array and the magnet part forms an electromagnetic force together with the current applied to each fixed contactor. Here, the electromagnetic force formed in the vicinity of each fixed contactor is formed in a direction away from the center of the space or in a direction away from each fixed contactor. Accordingly, a generated arc can be quickly extinguished and discharged by being induced by the electromagnetic force.

  • ARC PATH GENERATION UNIT AND DIRECT CURRENT RELAY INCLUDING SAME
    Publication number: 20230290598
    Abstract: 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 disclosure 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.

  • ARC PATH FORMATION UNIT AND DIRECT CURRENT RELAY COMPRISING SAME
    Publication number: 20230260728
    Abstract: An arc path formation unit and a direct current relay comprising same are disclosed. An arc path formation unit according to an embodiment of the present invention comprises a plurality of magnet parts. The plurality of magnet parts can form a magnetic field in a space inside an arc chamber to form an electromagnetic force for moving generated arc. The magnetic field formed by each magnet part forms an electromagnetic force toward the outside of the arc chamber. Electromagnetic forces formed adjacently to fixed contacts are formed in opposite directions. Therefore, the generated arc can be quickly moved to the outside and extinguished without damage to each constituent element of a direct current relay caused by the generated arc.
