摘要
介绍一种新型变压器局部放电在线监测系统的研制。该系统基于电声联合检测方法,检测出变压器局部放电产生的超声波信号。现场运行情况表明,该系统具有较高的检测灵敏度,可为电力变压器的状态检修提供可信的依据。
The development of novel partial discharge online monitoring system is introduced. The system combined with electric and acoustic detection method and can detect the ultrasonic signal of partial discharge of the transformer. The operation show that the system has high detection sensitivity which can provide credible basis for maintenance of power transformer.
