Description

Technical Field

[0001] The present invention relates to the technical field of cable fault detection, and in particular to a cable fault detection and repair device and method. Background Art

[0002] Aerial cables refer to power transmission cables installed overhead on utility poles, towers or other elevated structures. Such cables are usually fixed at high altitudes by brackets or insulators to cross terrain obstacles such as roads, railways, rivers, and oceans to transmit electricity from power plants or substations to users or other power facilities in different locations. During the long-term use of aerial cables, faults such as short circuits, breaks, and aging of the insulation layer may occur, resulting in power transmission interruptions, voltage fluctuations, current leakage, and power loss.

[0003] Therefore, the cable needs to be equipped with a detection device. Existing cable fault detection and repair devices such as fault indicators are electromagnetic induction devices that can reflect the passage of short-circuit current and display a fault sign (red card). This fault indicator is installed along the distribution line. Once a line fault occurs and a short-circuit current flows, the fault indicator will be activated and the fault sign red card will appear.
