摘　　要：云南某风电场35kVⅠ、Ⅱ回集电线路沿线海拔高程在2184~2536m之间,属于高原型山地风电场。经常受大风、低温阴雨等恶劣天气影响。该高原型山地风电场集电线自投产以来,在2016年1月及2018年2月出现过两次严重覆冰倒塔断线事故,已严重影响风电场安全稳定运行。因此提出倒塔断线原因分析并进行技术改造课题,从而提高35kV集电线路可靠性。The elevation along the 35 kV Ⅰand Ⅱ recombination lines of a wind farm in Yunnan is 2184-2536 m, which belongs to the plateau type mountain wind farm. It is often affected by bad weather such as strong wind, low temperature, rain and so on. Since the launch of the plateau-type mountain wind farm power collector, there have been two serious ice tower break accidents in January 2016 and February 2018, which have seriously affected the safe and stable operation of wind farm. Therefore, the cause analysis and technical renovation of broken tower line are put forward to improve the reliability of 35 kV power collection line.
