Background

When the overhead transmission line runs outdoors for a long time, tall and stable line towers are favored by birds and become the first choice for birds to nest and perch, and great threat is brought to the safe and stable running of the overhead transmission line. Birds nest and inhabit on the pole tower, hold conductive foreign matters such as branches, vines and iron wires and stay and shuttle between the wires and the cross arms, so that air gaps are shortened to cause short circuit tripping faults of the overhead transmission line. Birds defecate on a tower, bird droppings with proper viscosity can seriously distort an electric field around an insulator string, so that flashover faults are caused, and meanwhile, the bird droppings are accumulated on an umbrella skirt or a cross arm of the insulator string, so that the insulator string is polluted, flashover occurs, air gap breakdown occurs, and short circuit tripping accidents to the ground or interphase occur.

At present, the common measures for preventing and controlling the bird trouble include bird spikes, bird baffles, bird shields, windmill bird repellers, ultrasonic bird prevention devices and the like, but the effect of preventing and controlling the bird trouble is poor. The bird-preventing stabs can prevent birds from staying on the tower, but the protection range is small, fastening bolts are easy to rust, and steel strands are easy to deform; the bird-proof partition plate can effectively prevent bird droppings from falling, but cannot prevent birds from nesting and inhabiting on the insulator string; the bird prevention cover can prevent bird droppings from polluting the insulator string, but is easily influenced by wind power, poor in stability and easy to fall off; the windmill bird repeller can effectively prevent and control bird damage in the early stage of use, but the windmill bird repeller has the defects of easy aging, short service life, adaptability of birds to the windmill bird repeller after long-term use and the like. The ultrasonic bird repelling device can effectively repel birds, but has the defects of strong directivity, quick attenuation, low reliability, short service life, adaptability of birds caused by long-term use and the like.
