RELAY

WIPO Patent Application WO/2024/078461

A1

A relay, comprising a contact container (10), a pair of stationary contact lead-out ends (20), a first magnetizer (40), a movable component (53) and a tripping assembly (80). The pair of stationary contact lead-out ends are connected to the contact container, and the first magnetizer can move between a first position and a second position relative to the contact container. The movable component comprises a movable spring (54) and a second magnetizer (55), wherein the first magnetizer is arranged on the side of the movable spring facing the stationary contact lead-out ends, and the second magnetizer is fixedly connected to the side of the movable spring facing away from the stationary contact lead-out ends. At the first position, the distance between the first magnetizer and the second magnetizer is a first spacing; and at the second position, the distance between the first magnetizer and the second magnetizer is a second spacing, wherein the first spacing is greater than the second spacing. The first magnetizer is connected to the contact container by means of the tripping assembly, and the tripping assembly is used for releasing the first magnetizer when a magnetic attraction force between the first magnetizer and the second magnetizer is greater than a threshold value. The relay can have both the anti-short-circuit capability and the limit breaking capability.
