Abstract (en)
[origin: EP2023361A1] The device (1) has a sulfur hexafluoride gas filled metallic casing (2) accommodating three switches i.e. poles (R, S, T), and independent control apparatuses (3R, 3S, 3T) respectively activating movable contacts of the poles. Three mechanical transmission mechanisms (4R, 4S, 4T) are respectively connected to outlet shafts (30R, 30S, 30T) of the apparatuses and the movable contacts, where the apparatuses are placed at exterior and above of the casing. The mechanisms have different geometries and identical speed ratios irrespective of transmission instants during switching.
