| description | The utility model discloses a movable high-voltage power supply device, which belongs to the technical field of engineering machinery electronization and comprises a traction vehicle head, a battery vehicle and a voltage transformation vehicle are sequentially connected to the rear end of the traction vehicle head, a power battery pack is mounted on the battery vehicle, a voltage transformation device and a cable drum are mounted on the voltage transformation vehicle, and a high-voltage cable is wound on the cable drum. The power battery pack is electrically connected with the transformation device, one end of the high-voltage cable is connected to the transformation device, and the other end of the high-voltage cable is connected to the electric excavator through the coupler. The power supply device has the advantages that the power supply device has mobility, detachability, flexibility and structural variability, and can meet the operation requirements of the electric excavator when no external power supply |
