Abstract

A high voltage relay resistant to instantaneous high-current impact is disclosed. The high voltage relay includes an electromagnet system, a control system, a contact system, and a base support. In various embodiments, 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.
