Windage-yaw-preventing device for insulator applied to jumper of anchor support of power transmission line

Abstract

The invention discloses a windage-yaw-preventing device for an insulator applied to a jumper of an anchor support of a power transmission line. The device comprises a bowl head and a supporting pipe, wherein a ball rod is arranged in the bowl head in a matched mode, the bowl head is of a cuboid structure, a limiting hole is formed in one side of the bowl head, one end of a limiting pin penetrates through the limiting hole to stretch into the bowl head and is located on the outer side of the ball rod, a hanging tool is arranged below the bowl head, the bottom end of the hanging tool opens by a preset distance towards two opposite outer sides, the supporting pipe is transversely and fixedly connected to the two bottom ends of the hanging tool, the two ends of the supporting pipe are respectively provided with a fixing wire clamp, two clamping pieces are oppositely arranged on the lower portions of the fixing wire clamps, the middle portions of the two clamping pieces are matched with a cable to form a wire guide hole, and the lower portions of the two clamping pieces are fixedly connected through a bolt. According to the invention, the problems that the installation of a jumper of a power transmission line in the prior art is easily influenced by external force and windage yaw is large are solved; a safe distance between the jumper and an adjacent tower-side lightning conductor is ensured to be sufficient; and the phenomenon of discharging, the line-to-earth fault and the phenomenon of large-area power failure are avoided.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power transmission, and in particular relates to a wind deflection prevention device for jumper insulators of tension towers of power transmission lines. Background technique [0002] The jumper is the wire device of the wire tension clamps on both sides of the strain tower, which can keep the charged wire and the conductive part of the tower at a sufficient electrical safety distance. At present, on the power transmission line, the bowl head is mostly arranged under the insulator string, and the bottom of the bowl head is provided with a groove buckle suspension support tube for hooking jumpers. There are several problems in this way: [0003] 1) In order to adapt to the use of various voltage sizes, the bowl head is connected with a bat, but the bat has a large room for movement in the bowl head, and the bat is easy to shake when the wind blows, so that the lower support tube and the jumpe...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to propose a wind deflection device for jumper insulators of power transmission line tension towers, which solves the problem that the jumper installed on the transmission line is easily affected by external forces and has a large wind deflection, and ensures that the jumper and the adjacent tower side are protected against lightning The line safety distance is sufficient to avoid discharge phenomena, line-touching accidents, and large-scale power outages
