Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission and transformation lines, and more specifically to a maintenance-free high-voltage line anti-pollution flashover insulation and anti-bird cover. Background Art

[0002] At present, insulator flashover accidents on high-voltage transmission lines in power systems threaten the safe and stable operation of high-voltage transmission lines. After research and observation, it has been confirmed that insulator flashover is mainly caused by the droppings produced by birds when they rest on insulators. Therefore, it is necessary to prevent the droppings produced by birds from falling on the insulators of high-voltage transmission lines. The existing technology prevents the droppings produced by birds from falling on the insulators of high-voltage transmission lines by setting bird-proof covers above the insulators to ensure the safe and stable operation of high-voltage transmission lines.

[0003] The high-voltage line anti-pollution flashover composite insulation bird-proof cover is a device used for high-voltage transmission lines. Its main function is to prevent line pollution flashover and flashover, and can effectively prevent birds from touching the line, thereby reducing the line failure rate, improving the reliability and safety of the transmission line, and reducing the impact of line failures on the power supply system.

[0004] However, the existing bird-proof cover only covers the insulator alone and does not have an inductive adjustment function. Therefore, when birds perch on it, they cannot be expelled, which will cause pollutants such as bird droppings to corrode the protective cover, thereby reducing the insulation performance of the protective cover and further reducing the service life of the insulator.

[0008] Matching arc-shaped mounting plates are installed at both ends of the lower shell, and the high-voltage circuit is fixed on the arc-shaped mounting plates.

[0009] The flipping mechanism includes a double-axis motor installed on the top of the arc-shaped mounting plate, and the two output ends of the double-axis motor are connected to the driving shaft. The other end of the driving shaft is fixedly sleeved with a worm, and the top of the worm is meshed with a worm wheel, and the worm wheel is installed on the driven shaft.

[0013] 1. The utility model is provided with a flipping mechanism. When the device is used, the lower shell and the upper shell are arranged to shield and protect the insulator at one end of the high-voltage line, thereby effectively preventing birds and insects from perching on the insulator and causing flashover.

[0023] The flip mechanism 8 includes a dual-axis motor 81 installed on the top of the arc-shaped mounting plate 9, and the two output ends of the dual-axis motor 81 are connected to the driving shaft 82. The other end of the driving shaft 82 is fixedly sleeved with a worm 83, and the top of the worm 83 is meshed with a worm wheel 84. The worm wheel 84 is installed on a driven shaft 85. The driven shaft 85 as a whole passes through the bottom of the first connecting shell 21 and the second connecting shell 22 in the length direction, and the extended end is connected through a bearing and a fixed block 86, and the fixed block 86 is fixedly connected to the top of the corresponding end of the lower shell 1.
