摘要: 介绍了基于超声波法局放监测系统的原理,同时,阐述局放脉冲在理论分析上可以用单指数震荡衰减模型(SEAOW)和双指数震荡衰减模型(DEAOW)来进行模拟。阐述了基于超声波法局放监测系统定位出500 kV 气体绝缘金属封闭开关设备(GIS)在交流耐压局放试验中的放电击穿位置,从而验证了基于超声波法局放监测系统在耐压局放过程中寻找放电点是行之有效的,可为及早地发现GIS设备绝缘缺陷提供了有效检测方法和依据。

Abstract: The principles of ultrasonic-based PD monitoring system are introduced. At the same time, it is elaborated that the PD impulse can be imitated by SEAOW and DEAOW in the theoretical analysis. And then, it is described how to apply the ultrasonic-based PD monitoring system in locating the discharge position in the withstanding voltage and PD test of 500 kV GIS, which proves that the ultrasonic-based PD monitoring system is effective in detecting PD points in the withstanding voltage test. Therefore, it is an effective method and basis for timely finding defects in GIS.
