Abstract (en)
[origin: WO2010040574A1] The invention relates to a cutoff chamber for a high-voltage, greater than 52 kV, circuit breaker. According to the invention, a compromise is made between the operating energy to be deployed for all the values of short-circuit current be it symmetric or asymmetric and the effectiveness of the quenching of the arc which occurs on cutoff, by quenching the arc at the root (Z) through a part of the thermal expansion volume (when the cutoff chamber is of auto-pneumatic quenching type) or through the compression volume (when the cutoff chamber is of auto-quenching type) for arcs with a current whose value is greater than a given percentage of the cutoff value of the circuit breaker.
