摘　　要：鸟害给配电线路的安全运行造成了极大隐患,由此造成的线路故障逐年增加;鸟害的发生具有地域、时间和一定的杆型特性。线路在运行中因鸟起落造成相间短路,鸟巢在恶劣天气可引发单相接地,鸟的粪便掉落在绝缘子上易引发污闪等故障,给线路安全平稳供电造成很大的影响。对鸟害的治理采取安装驱鸟器、清除鸟巢,以及对线路裸露部位进行绝缘改造等措施效果较好,还可与改变开关安装方式、引线改为倾斜连接等多种措施相结合,以达到最佳的防治效果。Birds trouble poses a great hidden trouble to the safety operation of distribution lines,resulting in the increase number of line failures. The occurrence of birds trouble has region,time and certain rod characteristics. The rise and fall of birds can cause interphase short circuit when the line is running,bird nests in bad weather can cause single-phase grounding,and the bird excrement falling on the insulator can pollution flashover. All above faults can greatly influence the safe and stable power supply of the line. For the control measures of birds trouble,installing the bird repeller,removing bird nests and making the insulation transformation of the exposed parts of the line and etc. have good effects.Combined with measures such as changing the installation mode of the switch,changing the lead to the inclined connection,the best control effect can be achieved.
