Technical Field

The invention belongs to the technical field of overhead transmission line protection.

Background

Overhead transmission line passes through the fixed transmission conductor of the shaft tower that stands on ground to reach the purpose of long distance transmission electric energy. The cross arm is an angle iron vertically fixed on the upper part of the tower and is used for bearing insulators and hardware fittings, supporting transmission conductors and lightning conductors and guaranteeing safe and stable operation of the transmission line. With the national advocation of ecological environment protection, the number of birds and the range of activities are gradually expanded, and bird damage becomes one of the main problems causing transmission line faults. Birds nest on the cross arm of the tower, branches and iron wires fall on the wires or are inversely lapped on the wires and the cross arm, and short-circuit accidents are easily caused; birds stay near the cross arm of the tower, and excrement of the birds drops on the insulator, possibly causing flashover.

At present, the prevention and treatment method of bird damage mainly comprises physical, noise and mechanical defense mechanisms. Physical defense is a bird-preventing method that utilizes some fixed feature, including bird-preventing pins, umbrellas, and shields, among others. The density of sharp structures of the bird-proof needles and the umbrella spines is insufficient, so that birds with small volume cannot be prevented from perching and falling; if the sharp structures are sufficiently dense, they can also increase the difficulty and cost of the manufacturing process and can sting birds. Although the protection effect of the protection cover is good, the protection cover has a large volume and is easy to fall off, and inconvenience is brought to line maintenance work. The noise defense is a method for scaring birds by using audio frequency, and the method comprises an electronic buzzer and a bird scaring device, so that the aim of scaring birds can be fulfilled in a short period, but the method has poor effect after the birds adapt. Mechanical defence refers to a bird repelling method using a tumbling swing of an object, which is costly and prone to failure, and may also hit birds to fall from high altitudes and be killed.

In summary, the existing bird repelling method can only solve the problem of bird damage to a certain extent, but still has defects in long-term effectiveness and rationality.
