Device for reducing electric leakage loss

The utility model discloses a device for reducing electric leakage loss. The device comprises a shell, a rotating shaft and a plurality of rotating blades, the shell is a hollow cylinder; an electrolyte inlet and an electrolyte outlet are formed in the side wall of the shell so as to be connected with an external electrolyte pipeline; the rotating shaft and the plurality of rotating blades are accommodated in the shell; the axis of the rotating shaft coincides with the axis of the shell. The plurality of rotating blades are radially arranged around the rotating shaft and are fixedly connected with the rotating shaft; a flexible running-in structure is arranged at the front end of the rotating blade, and the rotating blade is in running-in with the inner side wall of the shell through the flexible running-in structure so that equivalent resistance can be formed through a running-in gap at the front end. According to the utility model, the leakage loss of the flow battery can be effectively reduced. 本实用新型公开了一种用
