摘要
变压器局放定位对于保障设备安全稳定运行具有重要作用,介绍了常见的局放定位方法包括光定位法、电气定位法、射线激励定位法、特高频电磁波定位法以及超声波定位法,对于现场应用较广的特高频电磁波定位法和超声波定位法的实施方法和优缺点进行了比较和分析。
It is very important for the partical discharge position of a tranformer to ensure the equipment to operate safely.The paper presnets common partialy position methods,including light position,electric position,ray exciting position,ultrahigh frequency electromagnetic wave position and ultrasonic position.The enforcement methods and strong and weak points of the ultrahight frequency electromagnetic wave position and ultrasonic position which are widely used at work place are compared and analyzed.
