DIRECT-CURRENT RELAY RESISTANT TO SHORT-CIRCUIT CURRENT

摘要

A DC relay resistant to short-circuit current includes two stationary contact leading-out terminals, a push rod component and a straight sheet type movable spring mounted on the push rod component. Upper magnetizers arranged in a width direction of the movable spring are mounted above a preset position of the movable spring. Lower magnetizers arranged mounted below the preset position can move with the movable spring. At least one through hole is provided in the movable spring at the preset position, so that the upper magnetizers and the lower magnetizers can approach one to another or come into contact with each other through the through holes; and at least two independent magnetically conductive loops are formed in the width direction of the movable spring by the upper magnetizers and the lower magnetizers.
