Results revealed that the large side insulation of the stator bar in slot is available for ultrasonic pulse-echo testing; Coupling transducer on the surface of a practical stator bar could minimize the influence on the measurements of velocity, contributing no destructivity of the ultrasonic testing for stator insulation; The simultaneity of same velocity and higher attenuation can be used to detect insulation delamination from conductors; Compared with the wide sides of the bars in slot, the short sides of the bars near the exit from slot and the end bars had a same velocity and a higher attenuation; The velocity might be exactly measured on the shot sides of the bars near the exit from slot and the end bars, while the attenuation might not, which were examined though filed tests; V min decreased greatly and V av decreased slightly with the service time of the bars.

在实验室对线棒多种结构处的主绝缘和不同运行年数(未老化、16、18 和23年)线棒的主绝缘进行了低频超声反射法检测试验，并进行了现场试验，发现(参见 Hao et al， IEEE DEI， to be published)，槽部线棒的宽面绝缘不受换位绝缘的影响，比窄面绝缘更适合超声测量；线棒表面平滑的半导体层减小了耦合剂对超声测量的影响，实现了无损性；波速不变而声衰减减小可以检测线棒出现绝缘与导体脱壳缺陷；出槽口和端部线棒的窄面绝缘与槽部线棒的宽面绝缘相比，声衰减大而波速一致；现场试验验证了波速不受绝缘结构和现场测试条件的影响，而声衰减受以上因素影响很大(参见 Hao et al，中国电机工程学报， Vol.23 No.4)； V min 随运行年数明显减小， V av 随运行年数慢慢越小。

Firstly, a signalized point is stuck on a moving object to be tested, a microphone array and two video cameras are arranged, and the video cameras are demarcated to obtain a projection matrix; sound pressure signals of a sound source in the moving object to be tested are obtained by the microphone in an array mode, the dynamic video of the moving object to be tested is obtained and disassembled into an image by the video cameras; the signalized point on the moving object to be tested is identified in the video image and the matched signalized point is treated with three-dimension reconstruction to obtain the spatial location of the moving object to be tested; the sound pressure signals are treated with beam forming treatment to obtain a sound field characteristic function scattergram of the moving object to be tested, the video image is treated with spatial coordinate superposition frame by frame and restored into a dynamic video image.
