Abstract

The invention relates to fault positioning equipment, system and method for a cable joint, and relates to the technical field of power monitoring. The fault positioning equipment comprises a metal wire and monitoring equipment, and the two ends of the metal wire are connected with the monitoring equipment; the metal wire is used for being attached to the side face of the cable joint in a surrounding mode and is broken when the cable joint breaks down. The metal wire is broken after the cable joint breaks down, when the monitoring equipment detects that the metal wire is in a broken state, set fault information is output, and the fault information comprises a fault result and information corresponding to the current monitoring equipment, namely, the position of the cable joint with the fault is directly positioned. According to the embodiment of the invention, whether the cable joint breaks down or not is determined by monitoring whether the metal wire wrapping the side face of the cable joint is broken or not, the fault position can be rapidly and reliably determined, and effective monitoring of the cable joint is realized.

Description

technical field

[0001] The present application relates to the technical field of power monitoring, in particular to a fault location device, system and method for cable joints. Background technique

[0002] In the technical field of power transmission and power distribution, cables are widely used because they are buried low and do not occupy ground space. Among them, cable faults mostly occur in cable joints. This is because most of the current cable joints are made manually on site. The poor contact rate and insulation performance of the cable core are lower than those of the factory-made cables, and the structure of the cable joint is complex and the electric field distortion is serious, so insulation breakdown faults are more likely to occur.

[0003] As the number of laid cables increases, the number of cable faults is also increasing. When the cable joint explodes, it is extremely inconvenient to find the fault point, which often requires a lot of manpower and material...
