Protection device for current guiding conductor of super-high voltage and ultra-high voltage transmission line and installation method of protection device

Abstract

The invention discloses a protection device for the current guiding conductor of a super-high voltage and ultra-high voltage transmission line and an installation method of the protection device and belongs to the technical field of current guiding conductor protection for ultra-high voltage and ultra-high voltage transmission lines. The super-high voltage and ultra-high voltage transmission linesare generally erected and connected through multi-split conductors; current guiding supporting spacers cannot be installed due to design, on-site construction and other reasons, as a result, the problems of the collision of current guiding conductors or current guiding tubes with other fittings, the abrasion and strand breakage of the current guiding conductors or current guiding tubes arise, andthe replacement of the current guiding conductors will waste a larger quantity of manpower, material and time. The protection device of the invention comprises a silicone rubber insulation sheath, asilicone rubber self-adhesive tape and a steel cable tie; the silicone rubber insulation sheath sleeves the conductor; the silicone rubber self-adhesive tape is wrapped around the silicone rubber insulation sheath; and the steel cable tie is fastened to the upper end and lower end of the silicone rubber self-adhesive tape. The protection device has the advantages of simple structure and convenientinstallation. With the protection device adopted, problems brought about by a condition that a traditional technology needs the replacement of conductors can be solved, and maintenance costs can be greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of protection of drainage conductors of ultra-high voltage and ultra-high voltage transmission lines, in particular to a protection device for drainage conductors of ultra-high voltage and ultra-high voltage transmission lines and an installation method thereof. Background technique [0002] At present, UHV and UHV transmission lines generally adopt multi-split conductors for erection and connection. During the line maintenance, it is often found that the drainage wire or the drainage tube touches with other fittings of the line and wears and breaks due to the inability to install the drainage support spacer bar due to design and site construction. The usual treatment plan is to replace the drainage wire or repair Drainage wires, but replacing the drainage wires will waste a lot of manpower, material resources and time, and treat the symptoms but not the root cause. The above problems will still exist in the long...

AI Technical Summary

Problems solved by technology

During line maintenance, it is often found that due to design, on-site construction and other reasons, the drainage support spacer cannot be installed, and the drainage wire or drainage tube is in contact with other fittings of the line, and the strands are worn and broken. The usual solution is to replace the drainage wire or repair it. Drainage wires, but replacing the drainage wires will waste a lot of manpower, material resources and time, and treat the symptoms but not the root cause, and the above problems will still exist in the long run
