Fault detection device for line loss management

The utility model relates to the technical field of line loss management, and discloses a fault detection device for line loss management, which comprises a detector and a plurality of detection interfaces arranged on one side of the detector, the bottom of the detector is fixedly connected with a base, and the top of the base is fixedly connected with a sleeve shell on the outer surface of the detector. A plurality of detection interfaces are formed in the base, a plurality of through holes are formed in one side of the sleeve shell, the through holes are matched with the detection interfaces respectively, sealing assemblies are constructed in the through holes respectively, ground plugs are arranged on the two sides of the base respectively, and a driving assembly for driving the ground plugs to rotate is arranged in the base. By arranging the driving assembly, the plurality of ground inserts can be conveniently driven to move synchronously, so that the ground inserts are inserted into the soil layer, the d
