Integrated device and method for first-aid repair of high-voltage cable line

Abstract

The invention discloses an integrated device for first-aid repair of a high-voltage cable line. The integrated device comprises a compartment body, a cable reel, a tool chamber, and a reducing joint main body; a first-aid repair cable is wound on the cable reel, cable plugging heads are connected to the two ends of the first-aid repair cable, the cable reel is connected with a driving device, and the driving device is used for driving the cable reel to rotate so as to unfold or fold the first-aid repair cable; the tool chamber comprises a generator set chamber and a tool cabin, a generator set is arranged in the generator set chamber to provide a power supply, and the tool cabin is arranged at the rear part of the tool chamber; two ends of the reducing joint main body are respectively provided with a first connecting hole and a second connecting hole, the diameter of the first connecting hole is larger than that of the second connecting hole, the first connecting hole is communicated with the second connecting hole, and two cables can be respectively inserted from the first connecting hole and the second connecting hole to realize connection. According to the integrated device for emergency repair of the high-voltage cable line, equipment is highly integrated, the reducing joint body capable of being flexibly transferred is configured, connection of a large-section cable and a small-section emergency repair cable on site can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the field of cable emergency repair equipment, in particular to an integrated device and method for emergency repair of high-voltage cable lines. Background technique [0002] The power cable system is the main form of urban power supply, and road landslides, tunnel fires, natural disasters and other reasons often cause cable lines to fail. In order to effectively respond to the rapid recovery of partial faults in power cables and avoid accidents such as large-scale power outages caused by damage to cables and equipment, a cable is usually temporarily laid next to the path of the original faulty cable to replace the faulty cable in the original cable path to achieve the shortest The purpose of restoring the temporary power supply of the cable line within a certain period of time is to make it capable of temporary power supply operation. [0003] At present, the construction of emergency repair of high-voltage cable lines is ma...

AI Technical Summary

Problems solved by technology

[0003] At present, the construction of emergency repair of high-voltage cable lines is mainly carried out by construction personnel temporarily calling cables to replace faulty lines. The cables need to be temporarily fabricated on site, which takes a long time; the integration of equipment is low, and multi-department coordination is required. Materials and equipment are used for emergency repair, which has low flexibility; the repair time is long and the efficiency is low; and it is often encountered that cables of different cross-sections are connected to each other.
