摘　　要：针对室内变电站主变室通风口的散热与噪声问题进行了研究,提出了采用往复振荡消声结构对室内变电站散热通风口进行消声降噪处理,并通过对宣化变电站噪声治理的工程实践,验证了往复振荡消声技术能在散热通风的同时起到降噪作用。The problems of heat emission and noise control at the ventilation vent of an indoor transformer substation were studied.The to-and-fro reflection noise elimination structure was designed and used in the noise control of Xuanhua transformer substation.It is shown that the to-and-fro reflection noise elimination technique is available in noise control with heat emission and ventilation.
