摘要
介绍了超声波检测技术用于支柱瓷绝缘子探伤的原理及应用,重点分析了超声波小角度探伤的实例,认为该方法使用时间不长,积累的经验有限,出现误判的概率很高,需进一步完善。
The principle and application of ultrasonic testing in high voltage post porcelain insulator internal defects detection were introduced, the example of small angle ultrasonic defects detection was selectively analyzed, it was considered that this method need to be further improved due to its short service time, limited experience and high probability of misjudge.
