Description

Power line protector

Technical Field

The utility model relates to a power line technical field specifically is a power line protector.

Background

An electric power line is a line used to transmit electric energy between a power plant, a substation and an electric power consumer, and is an important component of a power supply system, which is responsible for the tasks of transmitting and distributing electric energy. The power line needs to be connected with insulators during operation, and the insulators are used for supporting and fixing the bus and the live conductor and enabling the live conductor or the conductor to have enough distance and insulation with the ground.

Along with the improvement of consciousness of people for love and protection of birds, the number of the birds growing is increased, the birds frequently nest on a tower of an overhead power transmission line, so that the birds move such as dung discharge, the failure occurrence probability of a power line is high, and the safe operation of a power system and a power grid is seriously threatened.

The direct cause of power line tripping due to bird damage is bird nesting and feces removal. When birds stand on the upper component of the insulator to defecate, excrement can fall on the skirt edge of the insulator, and due to the fact that the excrement is adhesive, the excrement slides down along the skirt edge of the insulator and is continuously elongated, and the creepage specific distance of the insulator string is reduced. When the creepage specific distance of the insulator string is reduced to a certain degree, under the action of high voltage, a live wire can be caused to discharge to tower members along the insulator string, so that a line is tripped due to ground fault, and the so-called bird droppings wire drawing discharge is realized.

Meanwhile, long-time excrement discharged by birds is continuously accumulated on the insulator, so that the surface of the insulator is seriously polluted, a polluted layer is formed, the surface conductivity of the polluted layer is increased after the polluted layer is wetted under the meteorological conditions of fog, dew, frost, snow and the like, the leakage current of the insulator is sharply increased, partial discharge is generated, the local discharge is developed into along-plane flash cauterization, and the ground fault is caused to trip.

And when a bird nest is built on a component above the insulator, a nesting material used for building the bird nest held by the bird falls down and is wetted by rainwater, so that the insulator is easily shorted, and a line discharge trip fault is caused.

Most of the existing power line protection devices against bird damage are bird damage prevention devices such as bird spikes, bird prevention boxes, bird repellers and the like which are installed on an upper member of an insulator, but although the bird damage prevention devices can achieve a certain bird prevention effect in an initial stage, the bird prevention effect is reduced after birds gradually adapt to the bird damage prevention devices along with the increase of time. The protective effect on the insulator and the power line is insufficient, so that the bird damage still has certain threat to the operation safety of the insulator and the power line and influences the running stability of the power line.
