输电线路鸟粪故障分析与工程治理

为有效降低鸟粪故障跳闸发生的频次，通过分析研究其共性特点，找出鸟类体积尺寸和地理环境系数关键技术指标并进行了量化，建立了统一鸟害系数与防鸟害措施的一一对应关系，给出了体系建设过程中鸟类体积尺寸确定、防鸟技术分类、现场调查、防鸟害评估等具体方法和范例，由此建立了鸟害区段图绘制的理论基础，提出了混合型防鸟害技术思路和干字型塔中相吊串防鸟害新技术。实例应用表明，该治理技术效果明显。

Analysis of Transmission Line Fault Caused by Bird Droppings and Its Prevention

In order to effectively reduce the transmission line fault caused by bird droppings, we collect the data of bird sizes and their dwelling area geography information and analyze its common characteristics to establish the key technical indicators and quantify them. And the relationship between unified bird-hazard coefficient and prevention bird hazard measures is obtained. Then it provides the practical method and examples of bird size determination, spot field investigation and assessment of anti-bird measures. So, the theoretical basis for drawing the bird-hazard area distribution map is obtained. Finally, it proposes hybrid anti-bird technical ideas and new ways to eliminate the bird-damage to the middle phase insulator string on pole-type tower. Application examples show that the harnessing technology has obvious effect.
