摘要
介绍超声波检测原理及爬波检测和小角度纵波检测的特点,并描述爬波检测法在现场检测中的应用,通过实例证明超声波检测法可及时发现支柱瓷绝缘子内部和表面的缺陷,保证电网安全稳定运行。
The principle of ultrasonic detection and the testing characteristics of creeping waves and small angle longitudinal waves are introduced.The application of creeping waves in site inspection is also described.The ultrasonic detection method has been proved to be able to promptly discover both internal and surface flaws of strut porcelain insulators, hence ensuring security and stability of power grid.
