Electric operating device of transformer substation switch trolley and using method of device

The invention discloses an electric operating device of a transformer substation switch trolley and a using method of the electric operating device, the switch trolley is provided with an operating hole. The electric operating device comprises a shell; a storage battery arranged in the shell and used for supplying power; a driving motor arranged in the shell; and a rotating piece which comprises afirst end and a second end. The first end is connected with an output shaft of the driving motor, and the second end is inserted into the operation hole; along with rotation of the driving motor, therotating piece drives the operation hole to act, and then control over the switch trolley is achieved. The electric operation device adopts electric operation, the defect that a traditional operationhandle is prone to falling off in the operation process is avoided, the vehicle entering and exiting speed of the switch trolley is more stable, meanwhile, labor is saved, and the problem that a contact is prone to being damag
