(57) Abstract In three-pole, metal-encased, presssurised-gas-insulated high-voltage switchgear there is a single-pole encapsulated high- voltage power switch. Its breaker-units (2) located in the pressure chambers (4) are arranged with their axes (6) paral- lel and secured to a bearing component which also carries the drive casing(10). To improve the mechanical rigidity of the bearing component, there is a shared gear-casing (10) with two partitions (11) for the switching mechanism to which the breaker units (2) are secured via bearing rings. Supported by bridges (19), the bearing rings are located in front of three apertures (14) on a side wall (13) of the gear-casing (10) to the flange (15) of which the pressure chamber (4) is also secured. Inside the gear-casing (10) there are carries (22,22a) for the bearings (29,30) of the drive shafts (23,23a) extending from the partitions (11) or an outer wall (24). All bearing (20,38) and sealing surfaces (16,40) of the gear-casing (10) are in parallel planes and are to be clamped in. The entire gear-casing for the switching mechanism is suitable for single-pole encapsulated pressurised-gas-insulated high-voltage switchgear. * Sieh Rückseite
