Patent ID: 7199324

Claim:
A hybrid circuit-breaker comprises a dielectric-gas interrupting chamber ( 1 ) which contains a first contact ( 1 A) and a moving second contact ( 1 B) that are disposed longitudinally to a first axis (AA′) and in which the first contact ( 1 A) is connected to a first terminal ( 3 A) of a network, said interrupting chamber ( 1 ) being connected in series with a vacuum bottle ( 2 ) which contains a fixed contact ( 2 A) and a moving contact ( 2 B) that are disposed longitudinally to a second axis (BB′) and in which the fixed contact ( 2 A) is connected to a second terminal ( 3 B) of the network, actuating means acting via a single control ( 4 ) to move said moving contacts between respective open positions and respective closed positions, said hybrid circuit-breaker being configured to include a re-closure arrangement for performing a re-closing movement between the moving contact ( 2 B) and the fixed contact ( 2 A) of the vacuum bottle, wherein said single control ( 4 ) enables said re-closure arrangement to perform said re-closing movement when said moving contact ( 1 B) of said interrupting chamber is moving away from said first contact ( 1 A).
