摘要： Gas-insulated high voltage puffer breaker comprising a puffer unit with a movable piston running in a puffer cylinder and delimiting a puffer volume. A piston and a first contact member are attached to a piston stem. A piston and a first contact member are attached to a piston stem. An electric arc is extinguishable in an arcing zone when the first contact member moves from a first position to a second position. The puffer volume is fluidly connected to a gas nozzle by a gas channel such that the puffer volume comprises the gas channel as well as a portion of the puffer cylinder. The gas channel is provided radially outside of the puffer cylinder between a puffer cylinder wall delimiting the puffer cylinder and a wall structure of the puffer unit.

摘要： A reduction of the temperature of a blown gas, an improvement of a durability and a reduction of a maintenance frequency, a reduction of a current cutoff time, a reduction of drive and actuation energy, and a stabilization of a gas flow are accomplished. A pair of stationary arc electrodes 35a, 35b is disposed in a sealed container filled with an arc-extinguishing gas 1 to face with each other. A trigger electrode 34 in a rod shape with a smaller diameter is disposed between the stationary arc electrodes 35a, 35b so as to be freely movable. An insulation nozzle 81 is disposed so as to surround the trigger electrode 34. An accumulating chamber 42 to reserve the arc-extinguishing gas 1 having undergone pressure increase is provided, and a switch causing the accumulating chamber 42 to be in a closed state or a released state is provided. The switch includes gaps between the arc electrode 35b and the trigger electrode 34, and between the insulation nozzle 81 and the trigger electrode 34, and by closing the gaps by the moved trigger electrode 34, a closing component 45 is formed.
