US 12,665,150 B2 · Electric power interrupter and method thereof

Abstract

A novel electric power interrupter is provided, the interrupter comprising concentric springs and interlocking hooks for opening and closing the interrupter. The electric power interrupter further comprises a housing over a vacuum chamber and an electrically insulating layer around the vacuum chamber, a fixed section and a moving section. The butt contact of the fixed section is stationary, while the butt contact of the movable section moves towards and away from the fixed section. A toggle mechanism is provided for operating the movable section to open or close the interrupter. The present invention provides a better voltage dissipation and reduces the risk of electrical arcs forming outside the interrupter.
