Description
Technical Field
The invention relates to the technical field of electric power protection devices, in particular to a bird prevention device on a cement electric pole and a using method thereof.
Background
Along with the improvement of human environmental protection consciousness, the natural environment is gradually changed, the number of birds is increased rapidly, and the bird damage fault of the power transmission line is also increased obviously. According to the investigation, the trip frequency of the 220 KV line due to bird damage is only second to external force damage and lightning stroke flashover, and is positioned three positions before the trip reason of the line of the voltage class. Therefore, various bird prevention devices have been developed and are widely applied to bird damage prevention work of the power transmission line, and bird damage faults of the power transmission line are effectively controlled. However, in some areas, bird damage faults of the power transmission circuit are repeated continuously due to the fact that the bird protection stabs are not selected properly or the installation positions are not correct. Therefore, how to select the bird spike and correctly install the bird spike is very important.
Bird droppings flashover has two forms: one is flashover caused by the product of the insulator surface. However, because the bird is shielded and divided into a plurality of sections by the umbrella insulator, the probability of flashover directly occurring is very low in practice. The other is that the bird droppings slide and are insulated from the outside and fall, the straight nucleus causes short circuit discharge between the upper hardware and the lower hardware, and no bird droppings trace is left on the top of the insulator, which is also the main form of bird droppings flashover. The electric motor system of the Qinghua university researches a bird dung flashover mechanism and flashover conditions on the basis of successfully simulating the phenomenon of the flashover of an insulator bird, and considers that the electric field distribution around the insulator is distorted at the moment of bird dung falling, so that the air gap breakdown of a bird dung channel at the high end of the insulator occurs, and the insulator flashover is caused. Taking a 110 kV synthetic seed as an example, a protective model field is required in a circle with a diameter of 55 cm. Meanwhile, the bird droppings fall in a parabolic shape under the action of wind power. In actual work, the cross arm area at the top of the tower, which takes the insulator string as a base point and has an included angle of 30-45 degrees between two sides, is taken as an anti-bird key point.
The existing bird-proof baffle is limited by the cross arm, the synthetic insulator cannot be completely blocked, and birds like to fall at the joint position of the diagonal draw bar and the cross arm, so that the droppings can fall along the synthetic insulator, the short circuit and the brake drop of the insulator are caused, and the problem is solved.
