Problems solved by technology

These three vibrations will cause different degrees of damage to OPGW and transmission lines
Among them, the breeze vibration of OPGW is the most frequent, and the vibration lasts for a long time, which often causes fatigue and broken strands of strands, or even disconnection, resulting in communication interruption, which is very unfavorable to the stability of the power system.

Abstract

The invention provides a vibration-damping optical fiber composite overhead ground wire. On the premise of not affecting the quality and performance of the OPGW, it can reduce the vibration of the OPGW in the natural environment, reduce the phenomenon of strand breakage of the OPGW, and ensure the stability of communication. It includes an inner core conductor and an outer layer conductor, the inner core conductor includes an inner layer conductor, an optical fiber protection tube, and an optical fiber, the optical fiber is located in the optical fiber protection tube, and the optical fiber protection tube and the inner layer conductor are combined to form The inner core conductor is characterized in that: the outer layer conductor includes at least one layer, and the outer layer conductor of each layer is formed by a combination of several sections of arc-shaped metal wires with the same arc, and the innermost layer The first closed torus structure formed by the combination of the outer layer conductors, the combination of the outer layer conductors of each layer forms an independent closed torus structure, and the closed torus structure formed by the adjacent outer layer conductors The outer layer conductor opposite to the inner layer is arranged in the formed circular inner cavity.

Description

Technical field [0001] The invention relates to the technical field of overhead transmission lines, in particular to a vibration-damping optical fiber composite overhead ground wire. Background technique [0002] With the continuous development of the national economy, the smart grid, as the general trend of future grid development, has been highly valued by all sectors of society. Optical fiber composite overhead ground wire (OPGW), as the core component of the smart grid system, integrates overhead ground wires and communication functions The stability of its operation is directly related to the normal operation of the smart grid. During the normal operation, the vibration problem of the line is an important problem affecting power transmission. The existing optical fiber composite overhead ground wires are basically round. The wire is normally twisted and has no damping effect. It is exposed to the open field for a long time, and is affected by natural conditions (phoenix, rai...
