| 摘 要： | 污闪威胁到电力系统的安全运行。文章根据污秽放电伴随的超声信号，提出用声发射信号来反映绝缘子的污闪过程。进行了大量污秽试验，采集了绝缘子污秽放电时的声发射信号波形。分析结果表明声发射信号可以反映绝缘子污秽放电的强弱，因而可以实现绝缘子的污闪监测。

| Abstract: | Contaminant flashover is one of the primary dangers to electric power systems. In this paper, the method which can judge the working condition of the insulator based on the acoustic emission is given (AE method). A lot of experiments are performed, the AE signals have been acquired in the AC contaminant experiment. The analysis shows that the signal wave can reflect the insulator flashover, so the working condition of the insulator can be monitored. |
