Analysis of Noise Pollution and Control of 110kv Transformer Substations
IOP Conference Series Earth and Environmental Science(2019)
摘要
An example of noise control for the north gate of Quzhou110kV transformer substation. Based on the survey, measurement of the sound sources, and also result analysis, the acoustic enclosure with natural ventilation is designed by using the space around the main transformer and considering the heat dissipation of the main transformer, and also the maintenance requirement in the future. With dedicated acoustic modeling, the Cadna/A software prediction results show that the main transformer noise radiation to the measuring points of factory boundary near the residential area and residential area in the out of factory boundary decrease more than 12dB after the proposed noise control structure. After the superposition of background noise, the noise level of factory boundary and the sensitive point in the out of factory boundary reach to the 1 class sound functional area standard.
