Problems solved by technology

When birds defecate, nest, fly, peck and other activities on the transmission line, the excreted bird droppings form a conductive channel, which may cause the air gap breakdown of the tower, and the insulator may also have flashover and other problems. The big bird will directly cause a short circuit fault, seriously affecting the safe and stable operation of the transmission line

Abstract

The invention discloses a rotary bird repelling device at the cross arm of a power transmission line tower, comprising a first connecting rod, an inclined connecting rod, a base, a bird repellent holding box and an air chamber. The limit block is invented to adjust the deflection of the device. After the device is deflected, the effect of reflecting light and repelling birds is more obvious. With the vertical baffle inside the device, the airflow enters the air chamber from the air outlet, and is discharged from the whistle. The staggered air inlets on both sides of the rod can deliver airflow to the inside of the rod in real time to change the flow rate of the internal gas and adjust the sound of the whistle. The cross-arm can be effectively protected, and the upper part of the cross-arm can be effectively cleaned with the help of the obstacle removal rod during the rotation process, so as to avoid bird nesting.

Description

technical field [0001] The invention relates to the technical field of power protection, in particular to a rotary bird repelling device at the cross arm of a power transmission line tower. Background technique [0002] In recent years, with the improvement of the ecological environment and the enhancement of human's awareness of wildlife protection, bird activities have become more frequent. When birds defecate, build nests, fly, pecking and other activities on the transmission line, the excretion of bird droppings forms a conductive channel, which may cause the breakdown of the air gap between the tower and the tower, and the insulator may also have problems such as flashover. Big birds will directly cause short-circuit faults, which will seriously affect the safe and stable operation of transmission lines. From 2005 to 2014, a total of 1867 bird damage trips occurred on the 110(66)kV and above lines of the State Grid Corporation of China, accounting for 7.1% of the total...
