Abstract
A high voltage hybrid circuit-breaker has an arc circuit with a gas circuit-breaker connected in a series with a vacuum bulb. The housing is subdivided into a first compartment enclosed by an insulator for housing the primary contacts of the primary circuit and of the gas circuitbreaker and a second adjacent compartment (14) containing the vacuum bulb, defined by a conductive metallic shell. The movable arcing contact of the gas circuit-breaker is actuated with the movable primary contact by a primary control rod connected to a common mechanism, wherein the displacement of the movable arcing contact of the vacuum bulb is derived from the translational movement of the primary rod through an intermediate transmission lever received in the second compartment.
