Protection device for cable fault of power distribution network

The utility model discloses a protection device for power distribution network cable faults, which comprises the following steps: firstly, scanning a serial number on a power distribution network cable by a scanning identifier, transmitting cable information to an identification terminal, controlling the work of a telescopic assembly through the identification terminal, and driving a threaded rod II to rotate by a motor; the length of the longitudinal tool bit and the length of the transverse tool bit are adjusted through the recognition terminal according to accurate information of the cable, the recognition terminal is used for independently controlling the longitudinal tool bit and rotating the protection device, and the protection device is prevented from being damaged. Or the transverse tool bit is independently controlled to transversely pull the protection device, so that the protective maintenance of the cable is realized, and the maintenance quality of the cable is improved. 本实用新型公开了一种用于配电网电缆故障的防护装置，
