Abstract

The invention discloses a Y-shaped strain insulator string and a strain tower, and belongs to the technical field of power transmission. The Y-shaped strain insulator string comprises two strain insulator strings, a first connecting fitting, a first extension structure, a second connecting fitting and a first triangular linking plate, wherein the first triangular linking plate adopts a triangular structure; the top angle of the first triangular linking plate is connected with the strain tower through the first connecting fitting, the first extension structure and the second connecting fitting in sequence; and two base angles of the first triangular linking plate are connected with the two strain insulator strings respectively. The strain tower comprises a suspending point of the Y-shaped strain insulator string, wherein the Y-shaped strain insulator string is suspended on the suspending point. Through the flexible connection between the Y-shaped strain insulator string and the strain tower, the unbalance tension on the strain tower is lowered, the tower weight of the strain tower is further reduced, and the construction investment is reduced.

Description

technical field

[0001] The invention relates to the technical field of power transmission, in particular to a Y-shaped strain insulator string and a strain tower. Background technique

[0002] In the field of power transmission technology, long-distance power transmission is realized through overhead transmission lines. Overhead transmission lines usually use transmission towers to carry conductors. Cross arms are installed on transmission towers and insulator strings are connected through cross arms.

[0003] Transmission towers are generally divided into straight-line towers and tension-resistant towers. The insulator strings of straight-line towers are connected directly below the cross-arm, and the direction is the vertical direction, which only bears the vertical load of the wire and the horizontal load caused by the wind; The two sides of the load are connected, and the direction is consistent with the direction of the wire. It not only needs to bear the vertical and h...
