摘　　要：振动法是诊断变压器运行中潜伏故障的一种有效手段 ,能检测出故障绕组及铁心的状况。为此 ,论述了绕组正常状态及异常时变压器绕组的振动信号特征 。The vibration method is an effective method used for on-line monitoring the power transformer delitescent fault, it can monitor not only the winding, but also the conditions of core. It is a recommended method that should be studied deeply. In this paper, a method used to measure the vibration signal of transformer's winding was brought out, the vibration signal's characteristic of a power transformer's winding in normal and abnormal conditions was described. A method to estimate the condition of winding was brought out.
