The invention discloses an automatic control method for a 10-kv switch cabinet and a transfer trolley. The automatic control method relates to the switch cabinet, a switch trolley, a clamping device of the switch trolley, the transfer trolley, a transfer trolley crawler belt, a mechanical arm, a mechanical arm platform trolley, a mechanical arm platform trolley crawler belt, a grounded knife switch, limiting switches and approach switches. Centralized control is carried out through a PLC control cabinet, whether motions are in place or not is detected through the limiting switches or the approach switches installed at the corresponding positions, the motions are selected through a touch screen, the motion complete degree is displayed on the touch screen, and logical relations between the devices are achieved through programs. According to the automatic control method, on the basis of an original mechanical structure, a motor is adopted for driving, the labor intensity of workers is reduced, and the reliability and the safety performance of the devices are improved.
