Abstract (en)
Arc extinguishing arrangement comprises a shaft (50) carrying moving contacts (52), which rotates between contact engaging and disengaging positions. Two sets of fan blades (66, 68, 70, 72) are mounted on the shaft via the same slots (58) used to support the contact assembly, and are perpendicular to the contacts. Apertures (36) are provided in the set of blades extending from one side of the shaft which help to create turbulence in the insulating gas, e.g. SF6 or air. An Independent claim is also included for a fan blade for mounting on the movable shaft of a circuit breaker.
