Abstract
Each pole of the circuit-breaker includes a case ( ) containing two fixed conductive tubes ( ) which are aligned around an area provided for the pole contacts and each of which is connected to a connecting terminal. A semi-moving assembly includes a permanent contact member formed by the outside of a cylindrical member ( ) adapted to slide in a permanent contact member ( ) of a moving assembly and in the tube ( ). That member is carried by a member ( ) sliding in the tube ( ) which carries a wear contact member ( ) penetrating axially into an arc blast nozzle ( ) to which dielectric gas is fed by a piston ( ). A drive rod ( ) is moving between an inserted position in which the contacts are interconnected and another position in which they are separated. It operates through linkages to drive the assemblies and the piston differently.
