Research into Controll Methods of Bird Strike Damage on Overhead Contact System

为了减少鸟类活动造成的电气控制部件损坏、跳闸、机械补偿装置卡滞失灵等问题,保证电气化铁路的供电安全,结合电气化铁路接触网线路长、杆柱型号多、现场环境不一致的特点,分析鸟类活动对供电线路主要危害原因、鸟害发生的常见位置,以及现有的接触网鸟害防治措施,提出了通用性强、安装维护方便的主动驱鸟措施(如驱鸟器)。

The purpose of this research is to reduce the bird strike damages such as components breakdown or switch tripping in electric control system,and stagnation or failure in mechanical compensating devices,so as to ensure the security of the electrified railway.This article analyzes why and where the frequent damage from bird strike to the transmission lines,and analyzes the available control methods,in combination with the characteristics such as the long length of circuit,more types of support poles and various field environments in overhead contact system.Finally,the actively anti-birds measures(such as bird repeller) are proposed,which can be universal for actual application as well as be convenient for installation and maintenance.
