摘要
对一台220kV油浸式变压器,进行了变压器油箱的振动及噪声测试。通过对测试数据的时域分析和频域分析,给出了大型电力变压器的声振特性及传播规律。
For a 220kV oil-immersed transformer, the vibration and noise of the trans- former tank are tested. Through the time and frequency domain analysis of the test da- ta, the sound and vibration characteristics and propagation law of the large power transformer are presented.
