Description

An intelligent bird repelling device for iron towers of high-voltage transmission lines

technical field

The utility model relates to an intelligent bird-repelling device, in particular to an intelligent bird-repelling device for an iron tower of a high-voltage transmission line.

Background technique

With the strengthening of the country's nature protection policies for birds, the number of bird populations has continued to increase, the regional ecological environment has become better and improved, and the global climate has become increasingly warmer. Many northern migratory birds no longer migrate. Bird love and bird protection have increased the range of bird breeding and living, and the transmission line towers that are densely distributed in the open mountains have become one of the favorites of birds. Birds foraging, catching, nesting, resting and other activities have brought hidden dangers to the safety of the power grid. The rate of line fault trips caused by bird damage in various power grid accidents is also increasing, mainly in the following four aspects:

1. When the weather is cloudy and rainy or accompanied by gusts of wind, the wet bird's nest on the tower is blown away by the wind and falls on the live wire or insulator string, which will cause a short-circuit ground fault.

2. When birds build nests on transmission line towers, sticks, iron wires, firewood, metal mooring paper and other objects fall between the crossarm and the wires, which will cause instantaneous failure of the line.

3. Birds defecate on the cross-arm of the tower, thus causing the occurrence of insulator string pollution flashover accidents.

4. Some birds hold branches or copper, aluminum, iron wire heads abandoned by line construction, or eat small animals, and fly across the sky or between wires, which can cause grounding or phase-to-phase short circuits, causing line grounding trips.

In general, the rate of bird damage on 110kV-220kV lines is relatively high. This is related to bird perch height or 110kV and 220kV tower types. The cat head tower, the wine glass tower, the dry font tower and the ZG pole have all experienced bird damage trips. The ultra-high voltage 500kV line as the main power grid also has bird damage from time to time.

Due to the different climate and geographical conditions in different regions, there are also great differences in the faults of bird damage. According to the relevant statistical data of the State Grid Corporation of China, bird damage faults account for about 10% of all faults on the line, but the proportion of bird damage in individual provinces is relatively high. % (a certain year).

Frequent tripping of transmission lines due to bird damage directly threatens the safe and normal operation of the power grid. Effective measures must be taken to reduce tripping of transmission lines caused by bird damage and ensure stable and reliable operation of transmission lines.

At present, some lines adopt anti-bird devices. Anti-bird devices can be divided into two categories: one type includes anti-bird baffles, anti-bird covers, anti-bird thorns, anti-bird nets, anti-bird pull wires, windmills or flaps, etc. This type of anti-bird devices has a wider range of anti-bird Small, and after a long time, birds can adapt, and the effect of preventing birds is poor. Another class comprises acousto-optic bird-repelling device, bird scaring device, audio bird-repelling device etc., this class bird-repelling device has played certain effect, but see effect is not very satisfactory from the actual situation, there are many defects.

Such as a bird repelling device composed of silicon photocells, storage batteries, infrared switches, high voltage generators, electric shock wires, strong light generators, and sound generators. This kind of bird repellent is installed on the electric column or the cross arm of the tower. When the flying bird falls and steps on the electric shock wire, the line is turned on, and a sound and light signal is sent out, so that the flying bird is shocked and frightened, and flies away from the line, thereby preventing the transmission line from being damaged. Birds build nests. Its shortcoming is that only when the bird lands on the line, the bird repelling effect can be achieved, and the electric shock device is difficult to locate accurately, which is easy to cause mistakes and affects the power transmission line instead.

Another example is a kind of sound bird repelling device with a solar cell as a power source, including a sound generating device and a power supply. It is characterized in that the solar cell is used as the power supply of each circuit in the sound generating device; And at dusk, when birds are homing and frequent activities, they work regularly, which cannot provide effective comprehensive protection; and it can only send out a bird repelling signal when the birds stay on the power transmission line or on the iron tower to generate sound.

Therefore, up to the present, do not yet see on the market and can reduce bird damage, prevent transmission line from tripping, guarantee the stable, reliable operation of the bird repelling device of transmission line.
