Anti-bird type parallel gap and its installation method

Abstract

The invention discloses an anti-bird parallel gap and a mounting method thereof. The anti-bird parallel gap comprises an upper electrode (1), a lower electrode (2) and an insulator string (3), wherein the upper electrode (1) is directly connected onto a first insulator bowl head of the insulator string (3) in a covering mode; and the lower electrode (2) adopts a connection blot to be directly mounted onto a wire-end fitting of the insulator string (3). The upper electrode is adjusted in a clockwise or counterclockwise mode according to needs to enable a discharging terminal and the discharging terminal at the most front end of the lower electrode to be in the same plane. The anti-bird parallel gap of the invention has the advantages that the bird damage trip probability of an overhead transmission line can be greatly reduced, the lightning trip reclosing success rate is improved, the maintenance cost is saved, the mounting method is simple and reliable, and the mounting is quick and convenient.

Description

technical field [0001] The invention relates to a parallel gap for electric power engineering, in particular to a bird-proof parallel gap. The invention also relates to a method for installing the bird-proof parallel gap. Background technique [0002] my country's overhead transmission lines are distributed in many areas, most of which are located in remote mountainous areas. The vegetation below the lines is lush, and birds are active in the line corridors. At the same time, in the spring and summer of each year, lightning activities are frequent in southern my country. Large birds eating or excreting above the insulator strings of transmission lines are very likely to cause insufficient insulation distance and cause line tripping and power outages; at the same time, lightning overvoltages can easily cause line insulation breakdown and cause power outages, and may even lead to unsuccessful reclosing. In order to prevent bird damage and tripping faults caused by lightning s...

Large birds eating or excreting above the insulator strings of transmission lines are likely to cause insufficient insulation distance and cause line tripping and power outages; at the same time, lightning overvoltages can easily cause line insulation breakdown and cause power outages, and may even lead to unsuccessful reclosing

In order to prevent bird damage and tripping faults caused by lightning strikes on overhead transmission lines, operating units often install bird-proof devices, bird-proof baffles, lightning arresters, parallel gaps and other bird-proof and lightning-proof auxiliary facilities on the line, which have achieved certain results. Many auxiliary facilities not only increase the workload of line operation and maintenance, but also cost a lot to install multiple facilities
