| 摘 要： | 我国目前正在开展的特高压电网,由于线路参数发生变化,对OPGW的耐雷性能将提出更高的要求,在实践工程中应重点考虑。文章首先简要介绍了特高压电网的基本概念,分析了在特高压环境下OPGW在雷击性能方面与超高压环境的主要区别,并通过一些计算比较得出在特高压环境下由于引雷概率增大,则相应地提高OPGW耐雷能力的结论。

| Abstract: | At present UHV is being developed in our country.Because of the change of power line parameters,it will bring forward much higher requirement to withstand-lightning performance of OPGW,this requirement should be emphasized to consider in project.The article introduces the basic concept of ultra high voltage grid,analyzes the main difference of environment in the ultra high voltage and the extra high voltage.After some calculation,the conclusion is that the withstand-lightning capability of the OPGW ought to be improved because the probability of lightning strike increased in the environment of the ultra high voltage grid. |
