Abstract

The application relates to a direct-current relay. The direct-current relay comprises a moving spring sheet and an arc striking assembly; the arc striking assembly is arranged on the outer circumferential side of the moving spring sheet and comprises at least one arc striking magnet; wherein the surface of the arc striking magnet facing the moving spring sheet is a curved convex surface. The arc striking assembly can be applied to a scene in which the peripheral magnetic field of the moving spring sheet needs to be increased, can controllably adjust the arc striking strength and effect according to actual application needs, can avoid contact ablation, insulation deterioration, thermal runaway and system-level failure, and can effectively guarantee the safety and reliability of equipment.
