Description

一种高压输电线路杆塔驱鸟装置A high-voltage transmission line tower bird repelling device

技术领域technical field

The bird droppings will be damp and wet, which will cause the insulation performance of the insulator surface to decline or even flashover, which will affect the safe and stable operation of the transmission line.

为防止输电线路发生由绝缘子表面鸟粪污秽导致的闪络故障,输电线路维护人员耗费大量人力物力开展输电线路杆塔驱鸟工作,主要是进行人工驱鸟和安装常规驱鸟装置。人工驱鸟需要输电线路工作人员爬上杆塔,人工拆除鸟巢,工作量大。而常规驱鸟装置安装一段时间后,鸟类会产生适应性,仍然在输电线路杆塔周围驻留或筑巢,从而对输电线路安全运行带来隐患。In order to prevent transmission lines from flashover faults caused by bird droppings on the surface of insulators, transmission line maintenance personnel spend a lot of manpower and material resources on transmission line poles and towers to drive birds, mainly to manually drive birds and install conventional bird control devices. Manual bird repelling requires transmission line workers to climb up the tower and manually dismantle the bird's nest, which requires a lot of work. After the conventional bird repelling device is installed for a period of time, the birds will adapt and still stay or nest around the transmission line towers, thus bringing hidden dangers to the safe operation of the transmission line.
