摘要:
为解决高频大功率电抗器声学包电磁噪声过大这一共性问题,以某地铁能馈装置电抗器声学包为研究对象,对其振动噪声进行了系统试验;结合仿真对电抗器声学包振动噪声源和传递路径特性进行了详细的分析。结果表明:电抗器铁心磁致伸缩导致的高频结构振动辐射噪声是声学包的主要声源;电抗器柜百叶窗为主要的声传播路径,其声能比重高达80.14%。最后根据电抗器声学包的声源特性和声传播特性,制定了针对性的吸隔声优化方案,其综合降噪效果达8 dB(A)以上。研究结果对明晰高频电抗器振动噪声特性和电抗器柜声学包的优化设计有借鉴意义。
Abstract:
In order to solve the common problem of excessive electromagnetic noise in the high frequency electric reactor acoustic package, the subway energy feeder device was selected as the research object, and the vibration and noise tests of it were carried out systematically. Then, the characteristics of acoustic and vibration source and transmission path of the electric reactor were analyzed by combining test and simulation result. Results show that high frequency structural vibration and radiated noise caused by magnetostriction of reactor core is the main sound source of the acoustic package. The louver of reactor pack is the main acoustic transmission path and its sound energy proportion is up to 80.14%. Finally, A targeted sound absorption and insolation optimization scheme was developed based on the sound source characteristics and sound propagation characteristics of the reactor acoustic package, and the overall noise reduction effect was up to 8 dB(A). The research has great reference significance for the analysis of vibration noise characteristics of high frequency reactor and the optimization design of acoustic package of reactor pack.
