Positioning equipment for power distribution network cable fault detection

The invention discloses a positioning device for power distribution network cable fault detection, and relates to the technical field of electric power overhaul. The driving assembly is connected with the cable detector; wherein the cable detector moves outside the cable through the driving assembly. According to the positioning equipment for power distribution network cable fault detection, the driving assembly is adopted to drive the cable detector to move back and forth on the cable, so that the problems of inaccurate positioning and tedious detection process during positioning of existing fault positioning equipment are effectively solved, the detection difficulty of the cable is further reduced, and the detection efficiency is improved. The damaged position of the cable can be further positioned conveniently, so that the detection difficulty is reduced; due to the fact that an electromagnetic disc is adopted to drive a transmission gear to move between a second bevel gear and a connecting ring, the probl
