Background
The most important noise source equipment in each stage of the transformer substation is noise generated by a transformer and a reactor during operation, and the noise of the equipment basically determines the noise level of the transformer substation. The reasons for generating noise of large-scale power equipment such as transformers and reactors are basically the same, namely, the noise generated by the vibration of iron cores and windings mainly comprises the vibration of the iron cores caused by the magnetostriction of silicon steel sheets, the vibration of the iron cores caused by the electromagnetic force generated by magnetic flux leakage between joints of the silicon steel sheets and laminated sheets, the vibration of the windings and an oil tank caused by the magnetic flux leakage generated by load current, and the like.
At present, the reduction of noise of large-scale power transformers (reactors) at home and abroad is mainly implemented by taking measures in the aspects of improving iron core materials, processing, mounting processes, body structures and the like. Because the equipment such as transformer, reactor are the complicated structure of many physics field couplings such as electricity, magnetism, heat, power, vibration and noise, traditional design manufacturing approach not only consumes a large amount of manpower, financial resources and time, and the effect of making an uproar is not showing moreover.
