Zusammenfassung: | The present disclosure provides a high-voltage direct-current relay with a magnetic steel arc extinguishing function, comprising two static contact leading-out ends and a movable contact spring. The movable contact spring is arranged below the two static contact leading-out ends, and two ends of the movable contact spring are correspondingly matched with bottom ends of the two static contact leading-out ends, respectively. First magnetic steels are respectively arranged at the periphery of the movable contact spring corresponding to the contacts, and the side having polarity of each first magnetic steel faces the corresponding contact. In the two static contact leading-out ends, a third magnetic steel is also arranged on the side opposite to the static contact, the side having polarity of the third magnetic steel faces the corresponding contact, and the polarity of the side of the third magnetic steel facing the contact is opposite to the polarity of the side of the first magnetic steel facing the contact.
