为了解决变电设备噪声与振动给居民带来生活不便的问题,本文提出了变电设备噪声与振动装置,设计了变电设备噪声与振动控制系统。实验结果表明,本文研究的系统降噪效果相对较好,在距离变电站1 m时效果更好,噪声值由67 dB降低到48 dB,距离变电站22 m时噪声降到37 dB,并且本文系统检测噪声值与实际噪声值相差不大。
Abstract
In order to solve the problems of inconvenience caused by the noise and vibration of substation equipment to residents,a noise and vibration device for substation equipment is proposed,a noise and vibration control system is designed for substation equipment.The experiment results show that the noise reduction effect of the system studied in this paper is relatively good,and the effect is better when the distance from the substation is 1 m,the noise value is reduced from 67 dB to 48 dB,and when the distance from the substation is 22 m,the noise is reduced to 37 dB,and the system detects the noise value in this paper.It is not much different from the actual noise value.
