摘要
Abstract
In order to control the level of transformer noise of an 110 kV substation, the transformer and boundary noises of the substation in normal operation are measured and the results are analyzed. It is shown that the spectrum peak value of the 110 kV transformer noise is mainly concentrated in the frequency range of 100 Hz-2 000 Hz, and the noise is mainly the electromagnetic noise and cooling fan noise. Most of the boundary noise exceed the domestic emission standard. At last, the features, spectral characteristics and transmission laws of the noise of the 110 kV substation’s transformer are studied. And the major measures, which can make the noise at boundary of the substation to meet the standard, are proposed. This work provides a reference for noise control design of substations.关键词
