Gas-blast circuit breaker |
摘要 |
A puffer SF6 circuit breaker comprises a pair of separable contacts with formation of a breaking gap, a piston-cylinder assembly to compress the gas when the movable contact is actuated to the open position, and a puffer nozzle designed to channel the gas outflow to the breaking gap so as to cool the arc by forced convection. The nozzle is totally or partially made of transparent or translucent insulating material to allow a part of the energy to be removed by radiation.
