HIGH-VOLTAGE VACUUM RELAY

Disclosed in the present invention is a high-voltage vacuum relay. An upper sleeve is arranged at an upper end of a vacuum chamber, and a magnetic driving mechanism is arranged in the upper sleeve; a moving contact is arranged at a lower end portion of a sliding component in the magnetic driving mechanism that extends into the vacuum chamber in a sealed manner; and a static contact aligned with the moving contact is arranged in the vacuum chamber, and the static contact is connected to a terminal arranged on the surface of the vacuum chamber. In the present invention, the insulation performance is good, and there is no oxidation problem; an electric arc in a vacuum is easily diffused, thereby not easily causing the wear of a contact; the present invention also has the advantages of a high dielectric strength, a large rated bearing current, a large conversion current, a small contact resistance of the contact, stable operation, etc.; by means of the mutual cooperation of the structures, the problem of ablation
