    • A disconnector(100) and a switchgear(200) are provided. The disconnector(100) comprises a contact assembly(107) operable to change a status of a circuit, the disconnector(100) arranged in the circuit; shafts(101,102) adapted to be driven to rotate to operate the contact assembly(107); and a transmission unit(103) arranged between the shafts(101,102) and comprising: a plurality of gears(1031,1032) coupled to the shafts(101,102) to enable the shafts(101,102) to rotate with a mutual engagement of the plurality of gears(1031,1032); and a holding assembly(1033) adapted to hold radial positions of the plurality of gears(1031,1032) to ensure the mutual engagement of the plurality of gears(1031,1032). By arranging the holding assembly(1033) to hold the radial positions of the gears(1031,1032) to ensure the mutual engagement of the plurality of gears(1031,1032), only one input shaft(101) and one transmission unit(103) are enough to transmit large torques sufficient to operate the contact assembly(107), even in a case where the input and output shafts(101,102) are not coaxial. Accordingly, one sealing means is enough to well seal the disconnector(100). In this way, the complexity of assembly and costs are reduced.
