全户内式变电站降噪及散热治理技术

Audible-noise and heat-dissipation controlling technology of indoor substation

针对全户内式变电站出现站界噪声超标,影响附近居民生活的情况,文章在综合考虑降噪措施对主变压器室散热影响的前提下,提出了包括增加隔声声闸、加装消声器、扩大通风面积、增大风机出力等方式的优化降噪治理方案。方案实施后,既达到了降噪效果,又保证变压器散热冷却不受影响,确保变压器安全运行。

The residents around the substation are much affected for the acoustic noise problem. Considering the influence of noise controlling measures on the heat dissipation of transformer room, an optimized noise controlling scheme is put forward in this paper.In the scheme, the noise insulation door and the sound eliminator is installed, the ventilation area is enlarged, and the fun of large output power is adopted.The implementation result shows that the effect of noise cancellation is satisfactory, the heat dissipation of the transformer is not affected and the safety operation of the transformer is ensured.
