摘要
针对在电网中广泛运用的瓷支柱绝缘子爬波检测手段,结合超声基础理论,提出了瓷支柱绝缘子爬波检测波形分析方法,并在某变电站现场进行了运用。通过声振法、抗弯试验以及解剖试验,证明该分析方法能够快速准确辨别缺陷回波和大部分干扰回波。
Creep Testing method is widely used in post porcelain insulators testing. The article determined a waveform analysis method of creep wave testing of post porcelain insulators in the base of ultrasonic theories, and applied in a transformer substation. By acoustic vibration method, the bending test, and dissection test shows that this analysis method can accurately identify the defect echo and most clutter echo.
