摘　　要：对大型发电机采用声检测法得到的定子槽楔松动测量结果进行详细的研究分析。以声信号第一峰值点幅值作为表征槽楔松动程度的标准,提出一种纵、横比较结合的槽楔松动判据方法。实用结果表明:该方法测量精确,符合现场实际情况。The detail measurement results of the stator wedges＇ looseness in large generator by acoustic detection are mmlysed and studied. A wedges looseness estimation method of vertical and horizontal combination is proposed, and the first peak point amplitude of the acoustic signal is set in test results as the standard of wedges looseness level. The comparison of the experimental and manual detect results indicates that this proposed method is accurate and consistent with the field actual situation.
