基于超高频电磁波和超声波精确定位局部放电的方法

Method of Locating Partial Discharge Accurately Based on UHF Electromagnetic Waves and Ultrasonic

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。

The measuring and diagnosis of partial discharge has been one of the important method of evaluating the operating condition of high voltage electrical e- quipment. Online partial discharge detection and localization technology, cooperating by the ultra high frequency electromagnetic waves and ultrasonic （shorted as ＂acousic-electrical signal joint localiza- tion＂） ,has significant advantage in searching elec- trical equipment flaw and very good developing prospect for application. This paper introduced the method of detecting partial discharge and its local- ization theory based on ultra high frequency elec- tromagnetic waves and ultrasonic. It presents the expanded application of hand-handled partial dis- charge detector PDSlOO,and also provides a method,owning a certain value for reference,of lo- cating accurately partial discharge.
