Abstract: Gas-insulated high voltage puffer breaker (1) comprising a puffer unit (3) with a movable piston (4) running in a puffer cylinder (5) and delimiting a puffer volume (6). A piston (4) and a first contact member (2) are attached to a piston stem (9). An electric arc is extinguishable in an arcing zone (13) when the first contact member (2) moves from a first position to a second position. The puffer volume (6) is fluidly connected to a gas nozzle (12) by a gas channel (14) such that the puffer volume (6) comprises the gas channel (14) as well as a portion (15) of the puffer cylinder (5). The gas channel (14) is provided radially outside of the puffer (5) cylinder between a puffer cylinder wall (17) delimiting the puffer cylinder (5) and a wall structure (18) of the puffer unit (3).

Abstract: An HVDC circuit breaker unit (1) with an interrupter branch (2) extending between a first node (3) and a second node (4) comprising a vacuum interrupter (5) connected to the first node (3), and a gas interrupter (6) connected to the second node (4) of the circuit breaker unit. The vacuum interrupter (5) is connected to the circuit breaker unit (1) at a third node (7) such that the gas interrupter (6) is electrically connected in series to the vacuum interrupter (5). A first movable contact member (11) of the vacuum interrupter (5) and a second movable contact member (12) of the gas interrupter (6) are operatable by at least one Thomson coil drive. An arrestor branch (8) comprising a first non-linear resistor (9)is connected to the first node (3) and the second node (4).
