摘要
因抗干扰能力强、灵敏度高等优点,目前特高频法检测GIS局部放电在电力系统中获得广泛应用,其中天线是特高频检测系统中的关键组件之一。笔者在介绍特高频接收天线基本工作原理的基础上,分别综述了多种不同类型的内置及外置特高频天线的性能及结构特点,分析了用于GIS局部放电检测中各种天线的优缺点,并讨论了其发展的趋势。论文对天线的性能优化及新型天线的研制有重要指导意义,并可为GIS局部放电特高频检测系统中天线的选择提供依据。
The ultra-high frequency（UHF） detection method of partial discharge in GIS has been broadly adopted in power system owing to its high anti-interference property and sensitivity. Antenna is one of the important components in the UHF detection system. In this paper, the fundamental working principle of UHF receiving antenna is introduced, the characteristics and configurations of different built-in or external UHF antennae are summarized, and the merits and demerits of each antenna in detection of GIS partial discharge are analyzed. Moreover, the development trend of the antennae is discussed. This paper not only has a great guiding significance for the optimization of antenna characteristics and the development of new type of antenna, but also provides a basis for the choose of antenna used in the UHF detection system of GIS partial discharge.
