摘要
城市变电站的噪声污染作为环境污染的一种,近年来引起的居民投诉日渐增多。如何解决好城市变电站的噪声污染对周围居民的危害问题,已经成为电力部门和相关研究单位的当务之急。笔者通过对多座220 k V和500 k V电压等级的城市变电站开展噪声检测的基础上,归纳总结了城市变电站的几种主要噪声源,分析了各类噪声产生的机理,探讨了无源降噪和有源降噪方式,提供了无源降噪应用于变电站的技术实例,并对声屏障的结构提出了3种改进设计,这一工作可为城市变电站降噪的工程技术发展提供参考。
As an environmentalpollution, the noise pollution of the city substation has caused more and more complaints from the residents in recent years. How to solve the noise pollution problem has become urgent for the electrical company and related research units. Based on the detection to some 220 kV and 500 kV city substations, the article summarizes in several major noise sources of the city substations and analyses the mechanism of each kind of the noise. Meanwhile, it discusses the types of passive noise control and active noise control, as well as an application example for substation noise reduction technology by passive noise control. Then it provides three improved designs to the instruction of the sound barrier. The work will provide a reference for the development of the substation noise reduction engineering.
