摘要
研究雨天气候下导线-塔杆气隙击穿特性对于提高高压输电线路运行可靠性、预防击穿事故具有重要的意义。笔者通过人工模拟试验,研究了实际气隙和塔杆结构条件下,不同降雨强度、雨水电阻率、雨水运动路径等因素对气隙工频击穿特性的影响,得出不同雨强、雨水电阻率和雨水运动路径下导线-杆塔空气间隙工频击穿特性的变化规律。有关结论可为现场防风偏放电和输电线路设计提供依据。
It is important to study the air-gap breakdown characteristics between conductor and tower in rainy weather for improving the reliability of high voltage power grid. In this paper, the breakdown characteristics were studied through artificial simulation test, and the relationships among breakdown voltage and some factors, such as rain intensity, rainwater resistivity, and drop direction were investigated, and the corresponding results were obtained. This study wouht be helpful for design and maintenance of transmission line against rainy weather.
