摘要
对高电压设备绝缘缺陷的声学检测技术进行了分类,评述了国内外的声学敲击检测、声发射检测和超声检测等技术的原理、系统及优缺点,并探讨了绝缘状态声学诊断最有应用前景的检测技术。
In this paper, the acoustic techniques of electrical insulation for HV power equipments such as generator, transformer, cable, bushing, and line insulator are classified and analyzed. These acoustic diagnostic techniques include acoustic tap test, acoustic emission test and ultrasonic inspection and measurement. Also a lowfrequency ultrasonic inspection and measurement, which may open up a broad prospect in the diagnosis of insulation condition field, is discussed.
