Middle-phased direct-hanging bird-repellent device in strain tower shaped like Chinese character of gan and application method thereof

Abstract

The invention relates to a middle-phased direct-hanging bird-repellent device in a strain tower shaped like Chinese character of gan and an application method thereof, pertaining to the technical field of prevention of bird harms in overhead transmission lines. The technical scheme is characterized in that the middle-phased direct-hanging bird-repellent device in the JG-type strain tower comprises multiple first bird stabs, second bird stabs and third bird stabs. The first bird stabs are arranged on an upper plane of a cross arm. The multiple first bird stabs are arranged near a middle-phased direct-hanging insulator serial-hanging point and an overhead ground wire hanging point. The multiple second bird stabs are arranged in the cross arm of the overhead ground wire hanging point. Needle stabs are vertically and downwardly arranged. The multiple third bird stabs are arranged on iron steel on a lower oblique surface of the cross arm. The middle-phased direct-hanging bird-repellent device in the strain tower shaped like Chinese character of gan and the application method thereof have the following beneficial effects: the device is small in size, low in weight and long in service lifetime; the device is made by nylon material which is non-corrosive; high magnetic material is utilized for installation; the device is convenient to detach; the device is free from limitations such as mounting positions and directions; and the middle-phased direct-hanging bird-repellent device can effectively prevent birds from building nests above middle-phased direct-hanging isolators in the strain tower shaped like Chinese character of gan; and an extensive market space is obtained for inhabitation.

Description

technical field [0001] The invention relates to a combination device for preventing birds from being directly hung in the middle phase of a dry-shaped tension tower and a method for using the same, in particular to an anti-bird combination device capable of effectively preventing birds from building nests and inhabiting above the insulators directly hung in the middle phase of a dry-shaped strain tower. The combined anti-bird device belongs to the technical field of anti-bird damage for overhead power transmission lines. Background technique [0002] There are various types of overhead transmission line towers, and different anti-bird devices have different effects on different towers. Like a dry-shaped strain tower, the middle-phase vertical suspension and the lightning protection wire share a cross arm. The upper plane of the cross arm is horizontal and the lower side is inclined, showing a tapered three-dimensional frame structure. The hanging point of the lightning cond...

Problems solved by technology

After the birds build their nests, the guano seriously pollutes the insulators, reduces the insulation strength of the insulators, and easily causes flashover of the insulators. In rainy, snowy or windy seasons, metal objects such as iron wires in the bird's nests are scattered and easily cause short-circuit tripping of the lines. People defecate near the insulators before take-off, and the feces short-circuit the wires and crossarms, which may easily cause short-circuit tripping of the line
