ーブル事故区間の検出装置。[Claim for Utility Model Registration] Optical fibers of a distributed optical fiber temperature sensor are arranged along the longitudinal direction of a power cable line, and the temperature rise in the cable that occurs when a ground fault occurs is detected by the distributed optical fiber temperature sensor. In the cable accident section detection device, only one optical fiber is used in the three-phase cable line, and the optical fiber is curved at least at the connecting portions and connects all the connecting portions of the three-phase cable. A device for detecting cable accident sections that are in a state of failure.
