摘要
采用超声波技术来检测绝缘子是否存在污秽放电是当前国内外输电线路检修技术的发展方向,分析了一种新型的聚焦超声波传感器的结构原理及技术性能,介绍了基于该传感器的超声波技术在上海地区配电线路的现场应用情况,总结了一些经验并提出后续建议。
Detecting contamination partial discharge of insulator strings with ultrasonic technology is the world-wide development direction of transmission line maintenance.This paper analyzes the structure principle and technology features of a new focused ultrasonic transducer,introduces the application of the ultrasonic technology based on the focused sensor in Shanghai district.Finally,some experiences are summarized and some subsequent suggestions are proposed.
