Abstract (en)
[origin: WO2021165055A1] The invention relates to an extinguishing chamber (100) of magnetic blow-out type for a breaking device, said chamber comprising a field source (2), a magnetic carcass (3) and a breaking region (Z) in which an electric arc (E) is liable to form when a breaking pole (PC) belonging to said breaking devices is opened, said field source (2) being arranged to generate a magnetic field (B) intended to move said electric arc (E) in order to stretch it and accelerate its cooling and its extinguishment, and said carcass (3) being arranged to channel said magnetic field (B). It is characterised in that said carcass (3) is up against said field source (2) and closes in front thereof, to create a gap (D2) in the magnetic circuit formed by said field source (2) and said carcass (3) and to thus maximise the magnetic field (B) that passes through said breaking region (Z).
