| 摘要 | A clapping type electromagnetic tripping system comprises an iron core with a U-shaped structure, an armature, a heating element, a bimetallic element and a connecting plate; a bracket extends into a U-shaped groove of the iron core and is fixedly connected with the iron core, and a wire connecting the heating element and the connecting plate surrounds the iron core and the bracket; the bracket twined round by the wire is fixedly connected with the middle part of the heating element, the bottom end of the heating element and the bottom end of the bimetallic element are fixedly connected with a supporting member together, and the armature is hung on the bracket surrounded by the wire; and the armature and the iron core twined round by the wire are arranged oppositely to form a magnetic loop, and one end of the armature is attracted by the iron core so as to swing when short-circuit current is generated. The clapping type electromagnetic tripping system disclosed by the present invention-creation is simple and reasonable in structure and can enable the armature to be attracted reliably. | ||
