摘要
对电力电容器的局部放电的在线检测方法进行了分类阐述,对比了各种检测方法的优缺点及应用现状;概括了国内外各种检测手段(特别是超声波法)的研究成果;阐述了局部放电机理与绝缘失效之间的关系;揭示了电力电容器局部放电在线检测的发展前景和当前的研究重点。
The insulator damage caused by partial discharge in power capacitors, has attracted more and more attention. In this paper, the online detection method of power capacitor partial discharge is classified and expounded. The advantages, disadvantages and application detection method are contrasted. The research results of detection methods at home and abroad and the relation between partial discharge mechanism and insulation failure have been elaborated. At the last part, the paper reveals the development prospect and current study emphasis of online detection for power capacitor partial discharge.
