In recent years, with the improvement of the ecological environment, the range of bird activities has become larger and larger in number. As most of China's transmission lines run in the wild, by bird activities have a greater impact. According to statistics, by birds in the transmission tower roosting, nesting caused by line tripping, short circuit and other accidents is a rising trend year by year, the stable development of the power grid has caused a serious threat. Therefore, Dingsee smart editor for transmission line bird damage cause analysis and preventive measures were discussed.
Analysis of the causes of bird damage
1, electrical faults: bird droppings flash tripping, bird's nest short circuit tripping, etc.
2、Equipment failure: composite insulators are pecked, etc.
Among them, bird droppings flashover tripping faults account for a relatively high percentage. Due to the bird damage fault characteristics are not obvious, fault detection is difficult, and bird damage faults are frequent, if not dealt with in a timely manner, the fault point may also occur in the near future the same accident, which not only causes human and material losses, but also affects the safety and stability of power supply.

Bird prevention is mainly realized through expulsion and sheltering, for which we have developed a series of bird repellent products, bird spikes, bird repellers, bird covers, etc., which can effectively prevent and control bird damage.
1, anti-bird thorns: composed of 25 spiral steel wire, showing a scattered shape, like a large "steel shuttlecock", can prevent birds from landing on the tower, stay.
2. Bird repellers: wind bird repellers, ultrasonic bird repellers, laser bird repellers and so on.
(1) Wind-powered bird repellers: rotating with the help of wind power and fitted with reflective lenses inside, which use reflected light to deter birds and make them leave.
(2) Ultrasonic bird repeller: detecting the approach of birds through radar, sending out ultrasonic waves to stimulate the nerves of birds, combined with sound and light warnings, so that birds dare not approach.
(3) Laser Bird Repeller: By emitting a 532nm laser, it stimulates birds to stay away while simulating the voice of eagle, lion, firecracker, etc., so as to repel birds, and the effect of repelling birds is very good.
3. Bird-proof cover: By installing the device above the insulator string, it can block bird droppings or bird nesting materials from falling and provide a sheltering effect.
