[0026] As shown in the figure, this utility model discloses a driving device for a fast disconnect switch, including a support column 1, a support plate 2 installed on the outer side of the support column 1, and a connecting column 3 connecting the support plate 2 to the outer side of the support plate 2. The two support plates 2 are arranged in parallel. The support column 1 has a first through groove 101, and the two support plates 2 have a second through groove 21. The two support plates 2 are arranged symmetrically. Each of the two support plates 2 is provided with a bushing 4. A driving plate 5 is installed on the bushing 4 facing the support column 1. The outer ring of the driving plate 5 is provided with teeth 51. The driving plate 5 is located between the two support plates 2. The teeth of the driving plate 5 mesh with the teeth of a gear shaft 6. One end of the gear shaft 6 is connected to a reducer 7. The reducer 7 is connected to the output end of a motor 8. The front center of the driving plate 5 is connected to a connecting sleeve 9. A manual driving rod 10 is installed at the front end of the connecting sleeve 9. In normal use, the motor 8 drives the reducer 7 to work, the reducer drives the gear shaft 6 to rotate, the gear shaft 6 drives the driving plate 5 to rotate, and the driving plate drives the drive shaft of the disconnect switch to rotate. In an emergency, such as when the motor fails, a wrench can be used to rotate the manual drive lever 10.
