Abstract:
1. A driving gearing for a gas-insulated switchgear, comprising: a first mover linearly reciprocatable along a first linear axis being slanted with respect to a vertical axis; a ground breaking switch arranged along the first linear axis being slanted with respect to the vertical axis and contactable to the first mover; a second mover linearly reciprocatable along a second linear axis being slanted with respect to a horizontal axis, wherein the second linear axis intersects the first linear axis with an internal angle exceeding 90 degrees and less than 135 degrees, wherein the second mover has a first uneven end surface; a disconnector extended from a main line of the gas-insulated switchgear along the second linear axis being slated with respect to the horizontal axis and having a second uneven end surface which is contactable with the first uneven surface of the second mover; a first driven gear mated with and driving the first mover; a second driven gear mated with and driving the second mover; and a sector gear mated with the first and second driven gears and including i) a driving part having teeth formed on a part of a circumference of the sector gear and ii) a non-driving space having no tooth and occupying a remaining part of the circumference of the sector gear, the occupied remaining part being at least greater than one quarter of a whole circumference of the sector gear, wherein the sector gear drives the first and second movers at the same time while the driving part is mated with the first and second driven gears, the sector gear drives one of the first and second movers alone while only one of the first and second driven gears is mated with the driving part, wherein the sector gear does not contact with the other one of the first and second driven gears when the driving part is mated with only one of the first and second driven gears.
