降低配电房噪音的研究与实践

Study and Practice of Reducing the Noises of Power Distribution Substations

居民区配电房噪音污染已成为影响居民生活质量的普遍的问题,其中变压器产生的低频噪音是配电房噪音的主要构成部分。为此,可以在变压器底座加装自主研制的阻尼减震器,减少变压器的噪音和震动,阻隔变压器噪音的传播途径。同时采用在风机和支架之间加垫3mm厚的工业减震橡胶,在变压器与高、低压母排连接处采用柔性铜片连接等辅助措施,可大幅降低噪音,从而圆满解决居民小区配电房噪音扰民问题。

Noise pollution of power distribution substations at residential areas has become a common problem affecting life quality of the residents. Low frequency noise made by transformers is the key component of the noise of distribution substation. Therefore self-developed damper can be placed on the base of transformer to reduce the noise and vibration of the transformer and obstruct the noise from spreading. Meanwhile a 3ram industrial anti-vibration rubber can be placed between air blower and brackets. As a result, noise can be reduced considerably and the problem of noise can be solved satisfactorily.
