Mobile 110kV concentric high-voltage submarine cable integral testing system and method thereof

The invention relates to a mobile 110kV concentric high-voltage submarine cable integral testing system and a method thereof. An intelligent wire storage device is in a horizontal-type structure; a tray is axially arranged on a rotary plate in the center of the intelligent wire storage device; a terminal vertically penetrates through the center of the tray and is arranged at the central hole of the intelligent wire storage device; an electric submarine cable used for the concentric high-voltage test is wound on the tray, one end of the submarine cable is fixed with the terminal, and the other end of the submarine cable is connected with a tractor; the intelligent wire storage device drives the rotary plate to rotate by a motor so as to further drive the tray to rotate and works together with the tractor to wind up and release the cable; a terminal is fixed at two places need to be tested respectively; the two ends of the electric submarine cable used for the concentric high-voltage test are respectively arran
