Abstract

The invention provides a multi-pulse fault distance measuring device for a power cable. The device comprises a pulse fault distance measuring device, wherein a first supporting frame is arranged belowthe pulse fault distance measuring device, the two sides of the first supporting frame are detachably connected with second supporting frames, the two sides of each second supporting frame are symmetrically provided with two contraction supporting frames, and the second supporting frames and the two contraction supporting frames are each provided with a lifting wire structure. According to the invention, the transverse space occupied by the whole device during cable detection is reduced through the contraction supporting frames and the second supporting frames, and meanwhile, the cable is more convenient to install by utilizing the lifting wire structures.

Description

technical field [0001] The invention relates to the technical field of power cables, and mainly relates to a multiple pulse fault ranging device for power cables. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] Existing power cables use a pulse fault distance measuring device to detect the safety performance of the cables. [0004] However, in the production process of the power cable, the unwinding device, the detection de...
