摘要
通过分析现行绝缘子污秽监测方法的一些弊端,在这个基础上,研究了绝缘子污秽放电存在的声发射现象,提出了一种基于声发射技术监测绝缘子污秽放电的方法。研制了污秽放电监测装置并进行了大量试验。通过分析绝缘子污秽放电过程以及伴随放电出现的声发射现象,揭示出污秽放电的严重程度和声信号之间的关系,证明了通过监测绝缘子污秽放电发出的声信号可以实现对绝缘子污秽的在线监测。
The disadvantages of current monitoring method for insulator contaminant are examined. A method for monitoring insulator contaminant discharge is proposed based on the acoustic emission phenomenon. Monitoring device has been developed, and a large number of experiments are carried out. By analyzing the discharge process of polluted insulator accompanying with acoustic emission phenomenon, the characteristics of acoustic signal are studied. The relationship between discharge and acoustic signal is revealed, and a new method of insulator discharge monitoring based on the acoustic emission technique is put forward.
