Problems solved by technology

[0002] At present, high-voltage and ultra-high-voltage transmission lines, because birds land on the top of the cross-arm insulators of high-voltage iron towers, defecate and pollute the insulators, resulting in single-phase grounding or air gap breakdown of charged bodies, resulting in frequent line tripping accidents. The current bird-proof Thorns, wind blade runners, ultrasonic waves, sound waves, infrared lasers, etc., have unsatisfactory effects, such as: the bottom of the anti-bird thorns can still make birds stay and settle down, and the wind blade runners do not work when there is no wind. Ultrasonic, sound waves, infrared The laser and other methods have increased over time, and the birds have adapted to the environment and still do not work, and many other deficiencies

Embodiment Construction

[0012] This patent includes in the drawings: the umbrella-shaped cap fixed end (5) is made from the upper part of the umbrella-shaped cap (1), and the umbrella-shaped cap (1) is in an open state, which is convenient to be fixed on the insulator iron cap (2). The upper lap of the opening of the cap (1) is made with umbrella-shaped cap lap joint protrusions (6), the lower lap of the opening is made with umbrella-shaped cap lap joint grooves (7), and the umbrella-shaped cap of the umbrella-shaped cap (1) The fixed end (5) is conveniently fixed on the insulator iron cap (2) by the fixed clip (8), and the umbrella-shaped cap overlapping protrusion (6) and the umbrella-shaped cap overlapping groove (7) are pressed together to form a Integral, the umbrella-shaped cap (1) is integrally molded by polymer silicone injection. After installation, because the diameter of the umbrella-shaped cap (1) is relatively large, even if there are birds excreting on it, the bird droppings will not fal...

Abstract

The invention discloses a high-voltage insulator umbrella protection cap. The umbrella cap is formed integrally through injection of a polymer silica gel material; an umbrella cap fixing end is made on the upper part of the umbrella cap; the umbrella cap is in an opening state and is conveniently mounted and fixed on an insulator iron cap; and the opening of the umbrella cap adopts a lap joint mode, a lap joint convex strip is made on the upper lap joint edge, and an umbrella cap lap joint groove is made on the lower opening lap joint edge. In the case of use, the umbrella cap fixing end is fixed on the insulator iron cap conveniently by a fixing clip, and the umbrella cap lap joint convex strip and the umbrella cap lap joint groove are pressed together to form a whole. As the umbrella cap is made of the polymer material, the hydrophobicity is strong, rain, bird droppings and the like are not likely to be attached to the umbrella cap; as the umbrella cap has a large diameter, pollution to the upper part of the insulator is lessened; and the insulation degree of an insulator string is effectively improved, and the service life of the insulator string is prolonged.

Description

technical field [0001] This patent relates to the technical field of bird damage protection for high-voltage transmission lines, in particular to an umbrella-shaped protective cap for high-voltage insulators. Background technique [0002] At present, high-voltage and ultra-high-voltage transmission lines, because birds land on the top of the cross-arm insulators of high-voltage iron towers, defecate and pollute the insulators, resulting in single-phase grounding or air gap breakdown of charged bodies, resulting in frequent line tripping accidents. The current bird-proof Thorns, wind blade runners, ultrasonic waves, sound waves, infrared lasers, etc., have unsatisfactory effects, such as: the bottom of the anti-bird thorns can still make birds stay and settle down, and the wind blade runners do not work when there is no wind. Ultrasonic, sound waves, infrared Lasers and other methods have increased over time, and the birds have adapted to the environment and still do not work...
