Method for investigating bird damages of high-tension transmission line

Abstract

The invention discloses a method for investigating bird damages of a high-tension transmission line. The method comprises the following steps of: observing and recording species, quantities, discovery sites, ceasing positions, habitats of birds existing in the range of a belt transect, and species, nest types, nest materials, sizes, positions and use conditions of nesting birds on a pole of the transmission line by taking the high-tension transmission line as the belt transect and taking the widths by 50m on both sides of the high-tension transmission line as the width of the belt transect; measuring the length of the belt transect; and completing the investigation within 4 hours after sunrise, wherein the investigation period at least comprises a first half part and a second half part of a spring breeding season, and a first half part and a second half part of an autumn migration season. By the method, observation and simple measurement are primary, various bird damages existing on the conventional high-tension transmission line are detailedly and completely investigated, species group distribution, life habits, activity rules and damage degrees are found out, the cause of formation of the bird damages is analyzed, and a scientific basis is provided for preventing and controlling the bird damages of the high-tension transmission line.

Description

Technical field: [0001] The invention relates to a bird damage investigation method of a high-voltage transmission line. Background technique: [0002] The harm of birds to high-voltage transmission lines is generally divided into two types. One is that birds nest above the adjacent live parts on poles and towers, and rattans and other nesting materials fall, and short circuit insulators cause line tripping; The second is that the guano falls and pollutes the surface of the insulator, which reduces the insulation level outside the line and eventually causes the line to trip. A detailed and comprehensive investigation of the population distribution, quantity, living habits, and activity patterns of birds that are harmful to high-voltage transmission lines is the premise of preventing and controlling bird damage on high-voltage transmission lines. The prevention of bird damage on transmission lines provides a basis. At present, there is no systematic on-site investigation met...

[0002] The harm of birds to high-voltage transmission lines is generally divided into two types. One is that birds nest above the adjacent live parts on poles and towers, and rattans and other nesting materials fall, and short circuit insulators cause line tripping; The second is that bird droppings fall and pollute the surface of the insulator, which reduces the insulation level outside the line and eventually causes the line to trip

A detailed and comprehensive investigation of the population distribution, quantity, living habits, and activity patterns of birds that are harmful to high-voltage transmission lines is the premise of preventing and controlling bird damage on high-voltage transmission lines. Provide a basis for preventing bird damage on transmission lines. At present, there is no systematic method for on-site investigation of bird damage on high-voltage transmission lines in China
