Adaptive double-hung duplex suspension string

Abstract

The invention discloses an adaptive double-hung duplex suspension string, which comprises two upper hanging plates connected to a tower cross arm, two ball head hanging rings movably connected with the two upper hanging plates respectively, disk-type or composite insulators connected at the lower ends of the two ball head hanging rings, and socket hanging plates connected at the lower ends of the two insulators respectively. The adaptive double-hung duplex suspension string further comprises a link plate, the lower ends of the socket hanging plates are connected to the link plate, the link plate is provided with an arc-shaped rack, the inner side of the arc-shaped rack is provided with a tooth-shaped structure, the link plate is provided with at least two lower gears which are meshed with the arc-shaped rack, each lower gear is connected to the link plate through a hinge pin or a bolt, two ends of the arc-shaped gear are respectively connected to suspension clamps, and each suspension clamp is connected to a wire clamp. The invention aims to provide an adaptive double-hung duplex suspension string, wherein the suspension string is fixed in an insulated manner, thereby being conducive to insulation protection; and the height of the wire clamps is adjusted by using the gear structure according to the wire tension at two sides so as to ensure the clamps at the two ends to be stressed in a uniform and balanced manner.

Description

technical field [0001] The invention belongs to the field of power transmission lines, in particular to an adaptive double-hanging double-connection hanging string. Background technique [0002] In the process of transmission line design, double-connected suspension strings are often used in important spanning sections. However, when the double-connected strings of independent hanging points go out to the pole tower that goes up and down the mountain continuously, the force of the two hanging strings on the outlet line is often uneven, and even one string is stressed. Force and a string of slack situations. There are usually two methods as follows: (1) Double-connected single hanging point method is adopted, and the height of the two strings of hanging points is adjusted by twisting the joint plate, so as to automatically achieve the balanced force of the two strings, and reduce the charged point under the insulation and the grounding point above the insulation. (2) Use dou...
