Windage-yaw-prevention insulator anti-bird device with increased coverage

Abstract

The invention discloses a windage-yaw-prevention insulator anti-bird device with increased coverage. The windage-yaw-prevention insulator anti-bird device comprises an anti-bird cover mechanism and ananti-bird thorn mechanism. The anti-bird cover mechanism comprises an anti-bird cover body, an anti-bird needle mechanism and a cover body connecting mechanism. The anti-bird cover body is coaxiallyand fixedly connected to right the upper position of an insulator through the cover body connecting mechanism. The anti-bird needle mechanism is fixedly connected with the upper side of the anti-birdcover body. The anti-bird thorn mechanism comprises anti-bird thorns and an anti-bird thorn fixing piece. The anti-bird thorns are dispersed thorn clusters. The tail ends of the anti-bird thorn clusters are coaxially and fixedly connected to the anti-bird thorn fixing piece which is a rod piece. The anti-bird thorn fixing piece is fastened and fixed to a windage-yaw-prevention insulator overhung cross arm through two nuts. The anti-bird device has the advantages that the construction cost is low, use is safe and reliable, the anti-bird effect is remarkable, different anti-bird facilities can be selected to be used in cooperation with the anti-bird device according to various actual conditions, the anti-bird device is convenient and rapid to install and use, hot-line supplementing can be conducted, universality is extremely high, and the safety operation of a circuit is effectively ensured.

Description

Technical field: [0001] The invention relates to the field of electric power, in particular to a bird-proof device for wind-proof partial insulators with increased coverage area. Background technique: [0002] Bird droppings are the direct cause of high-voltage line tripping. Bird droppings accumulate on insulators for a long time, increasing the deposits on the surface of the insulators and forming a contamination layer. In addition, the influence of the external environment, such as rain, snow, frost, and fog, makes the insulators dirty and wet. In the case of high-voltage lines, the conductivity of the surface of the high-voltage line increases gradually, which increases the leakage current of the insulator, which in turn produces partial discharge, or even flashover along the surface, causing the line to trip due to ground faults. The transmission line is directly related to the safety and continuity of power transmission. If a trip occurs and the line is interrupted, so...

Problems solved by technology

[0007] Regarding the above-mentioned anti-bird measures, there are the following problems: For 1A4-DJ, 1B3-J1 and other types of corner towers, there are hanging wire crossarms extending from the tower head, and the anti-bird thorn cover cannot be installed above the windproof insulator. The board cannot be installed; the traditional bird-proof cover cannot be installed above the wind-proof insulator, and the model does not match. There is no bird-proof cover designed for the wind-proof insulator on the market today; there is still a bird-proof blind area above the bird-proof cover, and the traditional bird-proof cover The upper part provides a place for birds to stop, and the frequent activities of birds around the bird-proof cover also pose a safety hazard to the line

[0008] Therefore, in order to meet the requirements of anti-bird protection, it is necessary to increase the bird-proof coverage area, design a bird-proof cover with a suitable matching model, and solve the problem of insufficient bird-repelling ability above the bird-proof cover
