Description

Technical Field

[0001] The utility model relates to a bird-proofing device, in particular to a bird-proofing device at the bottom of an ultra-high voltage reactor. Background Art

[0002] my country has a vast territory, and most of the coal and water resources are concentrated in the western region. Therefore, the development of thermal power generation and hydropower generation in the western region, and then the transmission to the high-power consumption area in the east, is of great help to the country's environmental protection and energy conservation. Under the premise of the same diameter and the same transmission material, the higher the voltage, the smaller the line loss. Therefore, my country is vigorously developing 800kv and above ultra-high voltage transmission and transformation projects. One of the important equipment of the project, the ultra-high voltage reactor, will emit heat when working to form a warm environment on its top, which is easy to attract various birds to build nests here. Since the insulation level of branches and hay used by birds for nesting is very low, and the birds themselves are also easy to conduct electricity, it is easy to be broken down by the high-voltage reactor and cause a fire and burn the reactor, which brings great safety hazards to the safe operation of the national power grid. Therefore, there is an urgent need for an insulating, aging-resistant, anti-pollution flashover, heat-resistant and well-ventilated bottom bird-proof device to ensure the safe operation of the power grid. Summary of the invention

[0003] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and to provide a bird-proof device for the bottom of a UHV reactor which is insulated, well-ventilated, anti-pollution flashover, and resistant to aging and effectively prevents birds from building nests at the bottom of the reactor, thereby effectively solving the problem of birds building nests at the bottom of the reactor when the reactor is running.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a bird-proofing device at the bottom of an ultra-high voltage reactor, comprising a fiberglass frame, a fiberglass mesh body installed in the fiberglass frame; the fiberglass mesh body is installed in a bird-proofing net unit formed in a fan-shaped fiberglass frame, and multiple bird-proofing net units are combined and spliced ​​to form a disc-shaped bird-proofing device; a lining plate and a mounting hole thereon are provided on the inner side of the fan-shaped fiberglass frame, and are fixedly connected to the star arm of the reactor through the mounting hole; a layer of silicone rubber coating is sprayed on the surface of the fan-shaped fiberglass frame and the fiberglass mesh body.

[0005] In the present invention, the mesh holes of the FRP mesh body are square or diamond-shaped through holes, and the side length of the mesh holes of the FRP mesh is not greater than 20 mm.

[0006] In the present invention, the glass fiber reinforced plastic mesh and the lining plate are integrally formed or have a separate structure; in the case of a separate structure, they are fixed together by bonding with an adhesive.

[0007] The beneficial effect of the utility model is that the bird-proof device at the bottom of the UHV reactor is set to effectively prevent birds from building nests there and causing conduction or being punctured by the high-voltage reactor to cause fire and burn the reactor, which brings great safety hazards to the safe operation of the power grid. At the same time, it has insulation, aging resistance, anti-pollution flashover, heat resistance and good ventilation, ensuring the safe operation of the power grid.
