Background technique

With the continuous advancement of distribution network insulation and rural urbanization, the reliability of the power grid itself is increasing day by day. At present, the main reason for the tripping failure of distribution lines is external damage factors. Among the many external damage factors, the foreign body contact line occupies a large proportion, and among them, the nesting behavior of birds on the cross arm is a major cause of the short circuit of foreign bodies in the line. Although the insulation rate of distribution lines in Shanghai has reached nearly 100%, some electrical equipment such as high-voltage fuses, isolation switches, etc. still have exposed points, which have become the main points of failure of 10kV distribution lines.

The nesting of the bird's nest on the line cross-arm may easily lead to the overlapping of foreign objects in the line, resulting in single-phase grounding or phase-to-phase short-circuit faults. At present, the main anti-bird facilities mainly include anti-bird thorns, rotary (hawk-eye) bird repellents, and sonic bird repellents. These facilities reduce the probability of external breakage caused by birds to a certain extent, but there are still some problems.

Anti-bird thorns can only prevent the birds from suspending on the cross arm for a short time, and cannot structurally avoid the overlapping of the bird's nest. Rotary bird repellent has a certain effect of repelling birds, but it cannot be installed and used on all base poles, and cannot achieve bird repelling in a narrow area. The sonic bird repellent uses ultrasonic waves to drive birds away, and the effect is good, but it needs to provide a long-term power supply to work, and the equipment cost is relatively expensive.
