High-voltage DC relay

A relay, comprising:

• a contact container comprising an insulating cover and a yoke plate, the insulating cover being connected with a side surface of the yoke plate, the insulating cover and the yoke plate together enclosed to form a contact chamber, the insulating cover being provided with a pair of first through holes, each first through hole is in communication with the contact chamber;
• a pair of static contact leading-out terminals passing through the pair of first through holes, respectively;
• a fixing member, arranged within the contact container and fixedly connected with the yoke plate;
• a movable member movably arranged within the contact chamber and comprising a movable contact piece, the movable contact piece configured to come into contacted with or separated from the pair of static contact leading-out terminals;
• a moving part movable connected to the fixing member;
• and
• a first magnetizer arranged within the contact chamber and connected with the moving part;
• the first magnetizer being arranged at one side of the movable contact piece facing the static contact leading-out terminals;
• wherein the first magnetizer is movable relative to the movable member through the moving part and is configured to adjust a distance between the first magnetizer and the movable member according to a value of a current flowing through the movable contact piece,
• wherein the relay further comprises:
• a first elastic part for providing an elastic force to the moving part, so that the first magnetizer has a trend to move away from the movable contact piece, wherein the moving part has one end connected with the first elastic part, and the other end connected with the first magnetizer.
