摘要： A method and apparatus for suppling non-hydraulic power to a tool unit during well operation. A top drive (4) supplies power to a power consumer of the tool unit (200) with a non-hydraulic power supply: a mechanical power coupling from the top drive to the tool unit, a wireless power coupling from the top drive to the tool unit, a local power supply on the tool unit, and/or combinations thereof. The non-hydraulic power supply may be capable of supplying at least 2kW for at least 10s. The system may include a fixed gear (450) coupled to the top drive, a slewing ring (460) meshed to the fixed gear, and a revolving gear (470) meshed with the slewing ring and coupled to the tool unit. The slewing ring is configured to transfer rotational force from the fixed gear to the revolving gear, and may be rotated by rotating a torque shaft or actuating the fixed gear.
