摘要
随着开关柜绝缘故障问题的日益严重,为了保证开关柜的正常运行,文中结合暂态地电压(TEV)和超声波检测(AE)两种技术方法介绍了一种开关柜局放在线监测系统。文中详细介绍了这套系统的具体构架、检测技术原理及应用分析。该系统为开关柜局放监测提供了有力的决策支持。
With the insulation fault problem of switchgear becoming more and more serious, in order to keep the switchgear to operate stably, this paper introduces an on-line monitoring system online for partial discharge in switchgear by transient earth voltage (TEV) and ultrasonic (AE) technology. The architecture, technical principles and application analysis of the system is introduced in detailed. The system provides a powerfal decision support for partial discharge monitor of switchgear.
