    摘要： A gas-insulated low- or medium-voltage load break switch (1) comprises: a housing (2) defining a housing volume for holding an insulation gas at an ambient pressure; a first arcing contact (10) and a second arcing contact (20) arranged within the housing volume, the first and second arcing contacts (10, 20) being movable in relation to each other along an axis (12) of the load break switch (1) and defining a quenching region (52) in which an arc (50) is formed during a current breaking operation; a pressurizing system (40) having a pressurizing chamber (42) arranged within the housing volume for pressurizing a quenching gas from an ambient pressure p 0 to a quenching pressure p quench during the current breaking operation; and a nozzle system (30) arranged within the housing volume for blowing the pressurized quenching gas in a subsonic flow pattern from the pressurization chamber (42) onto the arc (50) formed in the quenching region (52) during the current breaking operation. The nozzle system (30) comprises at least one nozzle (33) arranged for blowing the quenching gas from an off-axis position predominantly radially inwardly onto the quenching region (52).

    摘要： The invention relates to a circuit breaker (10) for current at medium, high or very high voltage, comprising at least one cut-off chamber (12) as well as an outer envelope (14) in which is arranged the cut-off chamber (12). According to the invention, the circuit breaker comprises means (52) for sealing an opening (50) through an escape hood (40) of the cut-off chamber (12), the means (52) being displaceable between a sealed position and a withdrawn position in which they allow the passage of gas, the circuit breaker being configured in such a way that in its closure position, the sealing means (52) occupy their withdrawn position, and in such a way that the passage from the withdrawn position to the sealed position occurs in the course of an operation of opening of the circuit breaker.

    摘要： Circuit breaker (1) insulated by a dielectric fluid which comprises a first pair of contacts (10, 20), which can move in translation with respect to one another, an arc extinction chamber (30), a compression chamber (40) suitable for propelling a part of the dielectric fluid by piston effect into the extinction chamber (30). The circuit breaker (1) is adapted so that the dielectric fluid propelled by the compression chamber (40) is introduced into the extinction chamber (30) through an end of the first contact (10). According to one possibility of the invention, the extinction chamber is surrounded by a fixed thermal chamber perforated with orifices and thus ensuring blasting as close as possible to the arc contacts.
