摘要
采用超声波检测主要包括直探头纵波检测法、斜探头横波检测法、爬波检测法、小角度纵波检测法和双晶横波检测法等。其中,爬波检测法、小角度纵波检测法和双晶横波检测法是用于电网在役支柱瓷绝缘子及瓷套超声波检测的最常用技术。
Ultrasonic detection mainly includes straight probe longitudinal wave detection,angle probe shear wave detection,climbing detection,small angle longitudinal wave detection and double crystal shear wave detection method.Among them,the climbing detection method,small angle longitudinal wave detection method and double crystal shear wave detection method are the most commonly used techniques for detecting the grid post porcelain insulator and porcelain bushing in service.
