摘　　要：随着电网建设的不断发展和自然环境的逐步改善,输电线路走廊区域内鸟类活动造成的电网故障呈逐年增加的趋势。传统的驱鸟装置大多需要后期安装,需要运行维护和定期更换,在鸟类适应后防鸟效果逐渐降低甚至失效。本文采取“避”的思路,从杆塔结构设计源头出发,在杆塔设计时通过改变横担端部的结构型式,简化横担端部构造,降低鸟类在挂点上方筑巢的概率,从而降低鸟巢落物和鸟粪对绝缘子串的放电风险。通过此设计降低线路后期运维的工作强度,能大幅度减少防鸟费用支出。With the continuous development of power grid construction and the gradual improvement of the natural environment.The grid fault caused by bird activities in the corridor of the transmission line is increasing year by year.Most of the traditional bird-repelling devices require post-installation,which requires operation and maintenance and regular replacement.After the birds adapt,the anti-bird effect gradually decreases or even fails.This paper adopts the idea of"avoiding".Starting from the design of the tower structure,simplifying the end structure of the cross-arm and reducing the probability of nesting above the hanging point of the bird,thereby reducing the risk of bird nest and bird droppings discharging the insulator string.Through this design,the work intensity of the operation and maintenance of the line can be reduced,the cost of preventing birds is greatly reduced.
