摘要
在城市更新过程中,变电站电抗器的噪声对周围居民区的影响日益显著.首先,分析电抗器的工作原理和噪声特性;其次,以某变电站为例,确定电抗器噪声的传播路径,并建立电抗器噪声传播模型;再次,深入分析倍频程噪声的特性及其关系式,电抗器噪声主要集中在低频100～500 Hz,对居民区的影响较大;最后,从声源控制和传播路径控制两个方面探讨改造策略.
Abstract
In the process of urban renewal,the noise of substation reactors has an increasingly significant impact on surrounding residential areas.Firstly,the working principle and noise characteristics of the reactor are analyzed.Secondly,taking a substation as an example,the propagation path of reactor noise is determined,and a reactor noise propagation model was established.Thirdly,the characteristics of octave noise and its relation are deeply analyzed.Reactor noise is mainly concentrated in the low-frequency range of 100～500 Hz,which has a significant impact on residential areas.Finally,the transformation strategy is discussed from two aspects of sound source control and propagation path control.
