电力变压器空载状况下的振动特性研究

Study on the Vibration of Transformer under NO Load Condition

利用振动测试系统测试电力变压器空载状况下各相振动情况 ,以此研究空载时变压器器身的振动特性。该法与电力系统没有直接的电气连接 ,故效果良好 ,研究表明变压器器身振动基频为 10 0 Hz,10 0 0 Hz后谐波衰减至

The vibration method using on line monitor of the power transformer has no direct connection with the power system, it is a recommended method that should be studied deeply. In this paper, the vibration signal of power transformers under no load condition was measured, the vibration characteristic was described.
