Bird damage preventing method for composite insulator

Abstract

The invention provides a bird damage preventing method for a composite insulator, which can reduce the possibility of insulator flashover caused by bird damage. The bird damage preventing method is performed according to the following steps: (1) mounting a closed grading ring at the end of the composite insulator, wherein the closed grading ring comprises two semicircular boards, a connecting rod on the semicircular boards is connected through bolts, and the middle part of the connecting rod is provided with a semi-annular snap ring; and (2) mounting an anti-unfirm-closing outer sheath on the composite insulator, wherein the anti-unfirm-closing outer sheath comprises a sheath body with an upper opening and a lower opening; the side opening of the sheath body is provided with a connecting ear; the lower opening of the sheath body is relatively large; the lower inner diameter of the sheath body matches a projection on the composite insulator; an adhesive is coated in the sleeve body in mounting; a screw is used for connecting two connecting ears; and a fastener is used for fixing the anti-unfirm-closing outer sheath on the composite insulator. The bird damage preventing method has advantages of reducing pecking of birds to the insulator, reducing frequency of insulator flashover and line tripping, and realizing relatively easy mounting and updating of a bird damage preventing cover.

Description

technical field [0001] The invention relates to the safety problem of power transmission lines, in particular to a method for preventing bird damage on power transmission lines. Background technique [0002] Henan Power Grid is located in the Central Plains, and it is located on many migratory routes that migratory birds must pass. Compared with measures such as lightning protection and increasing mechanical strength, which have been carried out for a long time and have relatively mature technologies, the work of preventing bird damage on transmission lines is more regional and seasonal , the work of preventing bird damage is more targeted in terms of improving project quality and increasing economic benefits. [0003] Birds can cause flashover of insulators, leading to power outages in circuits, which is very harmful. The staff has adopted many methods to prevent flashover of insulators, for example: 1. Regularly check insulators by climbing poles and towers, and update the...

Problems solved by technology

Among these schemes, bird scarers are mainly used for prevention, but the preventive effect is limited, and the problem of insulator damage still exists. The hazards of bird pecking and bird droppings are still relatively obvious. In the end, it is necessary for the staff to climb up to replace the insulators.
