摘要
有效检测出电缆户外终端局部放电对保障电缆线路稳定运行十分重要。在介绍高频局部放电检测原理的基础上,结合一起110 kV户外终端典型案例,通过对检测数据的分析,详细论述了在户外终端应用高频局部放电检测进行局部放电信号判别和定位的方法。此外,通过对多起案例检测数据的分析并结合解体检查的结果,总结了户外终端局部放电检测的相关经验。
It is very important to detect the partial discharge(PD)of outdoor cable terminal effectively to ensure the stable operation of cable lines.Based on an introduction of the principle of high-frequency PD detection,the method of identifying and locating PD signal by high-frequency PD detection in outdoor terminal is discussed in detail combined with an analysis of the detection data of a typical case of 110 kV outdoor terminal.In addition,the relevant experience of outdoor terminal PD detection is summarized on the basis of an analysis of the test data from multiple similar cases and the results of disintegration examination.
