降低山区10kV架空线路树竹事故及减少树竹砍伐措施研究

Study on Reducing Bamboo Tree Accident in 10kV Overhead Line and Cutting Down Tree and Bamboo in Mountain Area

文章介绍了山区10k V线路设计及运行中预防树竹事故的传统方法和减少树竹砍伐的相关措施,提倡"坚强导线,坚强拉线,坚强避雷线"的山区线路设计理念,推荐采用高跨、穿越和局部使用电缆的线路设计方案,减少线路廊道内及周边树竹的砍伐,同时有效降低山区线路树竹事故发生概率。减少树竹砍伐的相关措施已在黄山地区线路设计中使用,实际运行效果良好,具备较好的实用性和推广性。

This paper introduces the traditional methods to prevent tree and bamboo accidents and the measures to reduce the felling of tree and bamboo in the design and operation of lOkV circuit in mountain area. The mountain line design concept of ＂strong wire, strong cable, strong lightning line＂ is advocated, and the design scheme for high span, through and local cables is recommended. It can reduce the cutting of bamboo in and around the corridor, and effectively reduce the probability of the occurrence of bamboo accidents in mountain area. The related measures to reduce the logging of trees have been used in the route design of Huangshan district, which has good practical effect and good practicability and generalization.
