Embodiment

[0026] refer to Figure 1-5 , a transmission line anti-bird flashover device, including a cross arm 1, the cross arm 1 is welded and fixed on a high-voltage line tower horizontally, an insulator 2 is fixedly embedded in the lower side of the cross arm 1, and a triangular baffle 13 is placed on the upper end of the cross arm 1 , the inner walls on both sides of the triangular baffle 13 are against the upper side of the cross arm 1 and the inner walls on both sides of the triangular baffle 13 and the upper side of the cross arm 1 form a cavity. It is fixed with the cross arm 1 by a fixing mechanism, and the setting of the triangular baffle 13 prevents the birds from nesting and resting above the insulator 2, thereby preventing the birds from defecating and falling on the insulator 2 to form a discharge channel, thereby preventing bird damage.

[0027] The insulator 2 is connected to the sliding sleeve 3 through the use of bearing rotation, the insulator 2 is welded and fixed wit...

Abstract

The invention discloses a power transmission line bird damage prevention flashover device. The device comprises a cross arm. An insulator is fixedly embedded in a lower side of the cross arm. A triangular baffle plate is placed at an upper end of the cross arm, inner walls of two sides of the triangular baffle plate abut against an upper side of the cross arm, and the inner walls of the two sidesof the triangular baffle plate and the upper side of the cross arm form a cavity, and clamping plates are rotatably connected to the two ends of the triangular baffle plate and fixed to the cross armthrough a fixing mechanism. When the device is installed at a top end of the insulator, a protection plate can prevent bird droppings from directly falling on the insulator and the bird droppings fallaround the protection plate of the insulator, a discharge channel cannot be formed, and an effect of preventing bird damages is achieve. And then, a multi-protection-plate device can be distributed and installed on the insulator, a specific creepage distance can be increased, the discharging channel is greatly prevented from being formed when ice and snow are melted, ice damage tripping is reduced, normal operation of a power transmission line is guaranteed, a solar cell panel is used for supplying power to a motor, natural energy is used, and a purpose of environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of bird damage prevention technology for transmission lines, in particular to a bird damage prevention flashover device for power transmission lines. Background technique [0002] With the continuous improvement of the ecological environment, the number of birds has increased and their activities are frequent, causing trips and power outages on power transmission and transformation lines due to bird damage. The towers of power transmission lines are the habitats that birds often choose. Nesting, egg laying, hatching, the bird's nest on the pole tower is blown away by the wind and falls on the live wire or insulator, which will cause a short circuit ground fault (flashover). Birds excrete feces every day, and some feces are concentrated in the early morning Birds standing at the top of the tower excrete in the air, especially the loose stools discharged by large birds, which cause single-phase grounding when ...
