Bird damage refers to transmission line damage caused by bird activities. With the improvement of the ecological environment, the number of various birds is increasing, bird damage failure is a rising trend year by year, to the transmission line, substation safety operation has brought a serious threat.
1, the main reasons for the occurrence of bird damage are as follows:
(1) Bird's nest. Nesting on high-voltage transmission towers, bird's nest material in rainy weather after absorbing water weight increases and lap conductor causing short circuit.
(2) Bird droppings. Bird droppings in the gear distance from the central wire suspension point on the steel wire, due to the lack of installation of anti-bird droppings cover or anti-bird droppings cover broken, bird droppings in the conductor side of the steel wire above the cross-bar, in the event of rain and other conductive substances contamination caused by the discharge of the tower.
(3) bird pecking. Bird pecking mainly occurs in the overhead bare wire, because the bird beak pecking the wire covered with ice when the wire outer aluminum strand pecking injury, resulting in wire strand breakage, the formation of a serious phase short circuit or grounding accident.
(4) Bird body shorting. Bird body shorting mainly occurs in the hanging insulator string above the jumper. When the birds are driven to the vicinity of the live wire, frightened to fly jump to the hanging vertical insulators near the equalizing ring, at this time, if the bird's two claws were grasped in the equalizing ring and the following conductor, that is, resulting in a short-circuit relative to the ground fault.
(5) Large birds spread their wings. Large birds flying or gliding between the conductor wings, body contact with three-phase conductors at the same time, resulting in phase-to-phase short-circuit faults.
In order to effectively solve this problem, Shenzhen True Bird Repellent Technology launched AI Intelligent Laser Voice Bird RepellerZQN-DZ-AI, the device with its high efficiency, intelligent, integrated bird repellent, for the safety of the power grid.
AI intelligent laser voice bird repeller combines AI video recognition technology, laser bird repeller technology, ultrasonic bird repeller technology and voice bird repeller technology. During the working process, the AI recognition system can actively detect birds, once a bird approaches, the bird repeller will quickly start the laser bird repellent function. At the same time, ultrasonic and voice speakers can be linked to comprehensive bird repellent.
1, 532nm wavelength green laser beam has a strong visual stimulation effect on birds, can effectively drive away birds without causing harm;
2, The ultrasonic generator will emit ultrasonic waves with a frequency of 8-35KHz, these sound waves are intolerable noise environment for birds, making them stay away;
3, Omni-directional voice speakers, on the other hand, play preset gunshots, wolf cries, gongs, eagles, firecrackers and other sounds to simulate threatening signals in nature, further enhancing the effect of bird repellent.
AI intelligent laser voice bird repeller is not only powerful, but also easy to operate, it supports IoT remote control, which can remotely and manually turn on the laser, ultrasonic or voice bird repeller function. In addition, you can also remotely modify the voice speaker sound source to configure more diverse sounds to adapt to different areas and different bird repelling needs.
It adopts the power supply method combining solar panels and storage batteries, and at the same time supports utility power supply to ensure a stable power supply. The equipment also has IP66 protection level, which can adapt to all kinds of harsh outdoor environments and ensure long-term stable operation.
