Abstract

The utility model discloses a medium-voltage electrical control device capable of remotely and automatically switching an electric submersible pump, which relates to the technical field of oil production engineering and comprises a device unit shell, a high-voltage inlet cable, a first medium-voltage outlet cable, a second medium-voltage outlet cable, a medium-voltage change-over switch, an electrical secondary control unit and a remote control unit. The two ends of the high-voltage inlet cable are connected with the output end of the boosting transformer and the control end of the medium-voltage change-over switch respectively, and the two ends of the first medium-voltage outlet cable are connected with a first wiring terminal of the medium-voltage change-over switch and a first electric submersible pump in the double-electric submersible pump producing well respectively. Two ends of a second medium-voltage outlet cable are respectively connected with a second wiring terminal of the medium-voltage change-over switch and a second electric submersible pump in the double-electric submersible pump producing well; and the electrical secondary control unit is connected with the remote control unit through a communication cable. According to the utility model, the technical problem that more labor time is occupied due to the fact that manual operation is needed in a traditional double-electric-pump switching mode is solved.
