Positioning method and device for detecting abnormity of overhead ground wire, equipment and medium

The invention discloses a positioning method, device and equipment for detecting abnormity of an overhead ground wire and a medium. The method comprises the following steps: determining a target area comprising a to-be-detected overhead ground wire and at least one to-be-detected overhead ground wire located in the target area based on a preset condition; for each to-be-detected overhead ground wire, the start end and the tail end of the current to-be-detected overhead ground wire are subjected to short circuit through a double-arm bridge tester, and the actual resistance value of the current to-be-detected overhead ground wire is determined; determining an abnormal target overhead ground wire from the to-be-detected overhead ground wires based on the actual resistance value and the corresponding theoretical resistance value of each to-be-detected overhead ground wire; and a half-folding processing method is adopted for the target overhead ground wire, and the abnormal position of the corresponding target ove
