摘要
本文将声学技术应用于大电机定子槽楔松动的无损检测中,研制出一套数字化声学检测系统,对发电机定子槽楔的松紧状态进行现场实测。提出了槽楔松动的定量标准。研究了松动槽楔在电机定子中的分布。为客观、准确、定量地检测发电机定子槽楔的松紧状态创造了条件。
This paper mainly introduces the application of the acoustic technique in generator wedge looseness non\|destructive testing.It has been found that characteristic peak value is consistent with wedge looseness.An on\|site test was performed through the acoustic detection system to detect stator wedge looseness in a generator.In addition,this paper studies the distribution of wedge looseness.
