Abstract (en)
[origin: CA2043558A1] A three-phase circuit breaker with self-extinguishing expansion and rotating arc comprises an arc extinguishing chamber per pole housing a pair of stationary and movable contacts, a coil to rotate -the arc, and an exhaust channel in at least one contact to provide on opening a communication and gas outflow between the extinguishing chamber and the expansion volume of an enclosure filled with SF6. The extinguishing chamber has a square or rectangular cross-section to resorb the gas plug after braking of the gas rotation movement, and improve stirring of the gas in the extinguishing chamber.
