Self-energy taking long-acting bird repelling device

Abstract

The invention provides a self-energy taking long-acting bird repelling device which comprises a bird repelling support and a self-energy taking device. The bird repelling support is mounted on a rod tower cross arm over an insulator chain through a bird repelling support fixing cross arm clamp, the bird repelling support comprises a PC insulation plate, a conductive aluminum alloy plate I, a conductive aluminum alloy plate II, a cable lug connecting plate I and a cable lug connecting plate II, the conductive aluminum alloy plate I and the conductive aluminum alloy plate II are mounted on the two sides of the PC insulation plate respectively, and the cable lug connecting plate I and the cable lug connecting plate II are mounted on the conductive aluminum alloy plate I and the conductive aluminum alloy plate II respectively. A self-energy taking device is mounted at the position, close to the upper portion of a transmission conductor, of the lower portion of the rod tower cross arm, andcomprises an insulation baffle fixedly connected with the rod tower cross arm through an insulation baffle fixing frame, an aluminum coil fixing frame, an aluminum coil, and an insulation wire connected with the two ends of the aluminum coil, and the aluminum coil fixing frame and the aluminum coil are mounted on the lower surface of the insulation baffle. The other end of the insulation wire is connected with the cable lug connecting plate I and the cable lug connecting plate II. The self-energy taking long-acting bird repelling device can aim at all bird-involved fault types and is effectivein a long term.

Description

Technical field [0001] The invention belongs to the technical field of high-voltage electricity, and specifically relates to a self-collecting long-term bird repellent device. Background technique [0002] With the improvement of the ecological environment and the increase of people's awareness of wildlife protection, the number of birds has increased dramatically. At the same time, the number of bird wading failures caused by the activities of birds on overhead transmission lines has also increased. According to statistics, in 2016, bird-related tripping occurred for the first time on a 750kV overhead transmission line, and the ±400kV diesel DC was also troubled by bird-related tripping. So far, bird-related trips on transmission lines have accounted for 10% of the total number of trips. That is, bird-related faults have become the third major cause of transmission line trips after lightning strikes and external force damage, which seriously affects the complete and stable opera...

So far, bird-related fault trips on transmission lines have accounted for 10% of the total trips, that is, bird-related faults have become the third largest cause of transmission line trips after lightning strikes and external force damage, which have seriously affected the complete and stable operation of transmission lines

[0003] At present, in order to solve the above-mentioned bird-related faults of transmission lines, line operation and maintenance personnel have installed different types of anti-bird devices on transmission lines, such as anti-bird boxes, anti-bird thorns, sound and light bird repellents, etc., which have achieved certain results in the early stage. However, with the passage of time and the adaptation of birds to the anti-bird device, the problem of failure of the anti-bird device will appear; at the same time, these anti-bird devices can only prevent and control a certain type of bird-related faults, and the It is impossible to prevent and control all bird-related faults; moreover, line operation and maintenance personnel are very deficient in bird knowledge, which will lead to great blindness in the prevention and control of bird-related faults, resulting in insufficient investment in the prevention and control of bird-related faults reasonable and wasteful
