Description

Technical Field

[0001] The present invention relates to the technical field of spacer bars, in particular to a damping spacer bar for a transmission line and a working method thereof. Background Art

[0002] The main purpose of the spacer is to limit the relative movement between the sub-conductors and maintain the geometric shape of the split conductors under normal operation. Currently, 220KV and 330KV transmission lines use two-split conductors, 500KV transmission lines use three-split and four-split conductors, and ultra-high voltage transmission lines with voltages above 500KV use six-split and more-split conductors.

[0003] Publication No. CN202222615699.5 discloses a four-phase conductor spacer for phase-to-ground spacers, comprising a spacer frame, wherein the inner walls on both sides of the spacer frame are fixedly connected to the two ends of a support rod I, the middle of the support rod I is fixedly connected to the middle of the support rod II, and the two ends of the support rod II are fixedly connected to the inner walls on the other two sides of the spacer frame, and the outer wall of the spacer frame is rotatably connected to a plurality of rotating columns, and the rotating columns are fixedly connected to a threaded rod at one end away from the spacer frame, and an internal threaded barrel is provided on the outer side of the threaded rod through a threaded structure, and a wire clamp is fixedly connected to the end of the internal threaded barrel away from the threaded rod. By means of the transmission-arranged threaded rod and the internal threaded barrel, the extension length of the wire clamp can be adjusted, and thus the transmission lines of different spacings can be clamped, which facilitates the installation of the spacer and reduces the manpower required to manually pull the transmission lines. The threaded rod is then rotated in the opposite direction to shrink the wire clamp, thereby adjusting the spacing between the transmission lines to the appropriate distance.
