Abstract: Embodiments of a disconnector and a switchgear, wherein the disconnector comprises a contact assembly operable to change a status of a circuit, the disconnector arranged in the circuit; shafts adapted to be driven to rotate to operate the contact assembly; and a transmission unit arranged between the shafts and comprising: a plurality of gears coupled to the shafts to enable the shafts to rotate with a mutual engagement of the plurality of gears; and a holding assembly adapted to hold radial positions of the plurality of gears to ensure the mutual engagement of the plurality of gears. By arranging the holding assembly to hold the radial positions of the gears to ensure the mutual engagement of the plurality of gears, only one input shaft and one transmission unit are enough to transmit large torques sufficient to operate the contact assembly.
