【摘要】 局部放电的测量和诊断已成为评估高压电力设备运行状态的重要方法之一。超高频电磁波和超声波相配合的局部放电带电检测和定位技术(简称"声-电信号联合定位")在查找电力设备缺陷方面优点显著,具有很好的应用发展前景。本文介绍了基于超高频电磁波和超声波原理的局部放电检测方法和定位原理。对手持局部放电检测仪PDS100的应用拓展作了介绍,提供了具有一定参考价值的精确定位局部放电的方法。更多还原

【Abstract】 The measuring and diagnosis of partial discharge has been one of the important method of evaluating the operating condition of high voltage electrical equipment.Online partial discharge detection and localization technology,cooperating by the ultra high frequency electromagnetic waves and ultrasonic(shorted as "acousic-electrical signal joint localization"),has significant advantage in searching electrical equipment flaw and very good developing prospect for application.This paper introduced the method of detecting partial discharge and its localization theory based on ultra high frequency electromagnetic waves and ultrasonic.It presents the expanded application of hand-handled partial discharge detector PDS100,and also provides a method,owning a certain value for reference,of locating accurately partial discharge.更多还原
