基于超声波注入的GIS盆式绝缘子表面状态检测装置及方法
摘要：
本发明公开了一种基于超声波注入的GIS盆式绝缘子表面状态检测装置及方法，将超声波注入传感器放置在GIS盆式绝缘子和GIS腔体交接面处，通过脉冲激励源激励注入传感器产生超声波信号，利用超声波接收传感器在盆式绝缘子对侧进行信号的接收。通过比较设备刚投运时的接收信号及运行若干时间后的接收信号进行盆式绝缘子表面污秽状态的判断。该方法针对GIS盆式绝缘子表面状态无法带电检测的难点提供了一种可在设备运行过程中带电检测的方法。
摘要（英）：

The invention discloses a GIS basin-type insulator surface state detection device and method based on ultrasonic injection. An ultrasonic injection sensor is placed at the interface of a GIS basin-type insulator and a GIS cavity, the injection sensor is excited by a pulse excitation source to generate an ultrasonic signal, and an ultrasonic receiving sensor is used for receiving the signal at an opposite side of the basin-type insulator. The dirty state of a surface of the basin-type insulator is judged by comparing a received signal when the equipment is just put into operation with a received signal after running for a plurality of times. Aiming at the difficulty that the surface state of the GIS basin-type insulator cannot be detected in a live-line manner, the invention provides a live-line detection method in the operation process of the equipment.
