Abstract
A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.
Claims13
A high voltage relay resistant to instantaneous high-current impact, comprising:
- an electromagnet system, a control system, a contact system, and a base support, wherein the electromagnet system is connected to the control system, and the electromagnet system is configured to generate a magnetic field to provide a driving force for the control system;
- the control system is connected to the contact system, and the control system is configured to control contacts in the contact system to open and close;
- and the contact system generates an electromagnetic force when an instantaneous high current passes the high voltage relay, to offset an electric repulsion force between the contacts;
- wherein the contact system comprises a current inflow plate, a movable copper plate, a connecting piece, a current outflow plate, a movable contact, and a static contact ;
- the current inflow plate and the current outflow plate are fastened on the base support;
- the movable contact is fastened on the movable copper plate, and the static contact is fastened on the current outflow plate;
- and the connecting piece is riveted or welded onto the current inflow plate and the movable copper plate;
- and
- wherein the connecting piece is a soft connecting piece.
