| Abstract: | With the rapid development of urbanization and electric power industry,the impact of noises in substations on inhabitants nearby has become increasingly obvious.The characteristics of noises in different types of substations were discussed.The effects of surface density,airspace thickness and fiber categories of aluminum fiber panels on sound absorption coefficients were investigated.The results indicate that the sound-absorbing panels with cutting aluminum fibers have some good features on noise-absorbing and technical economy.Applications of cutting aluminum fiber panels in 110 kV indoor substations were introduced,which expounded the wide perspectives of combination applications of cutting aluminum fiber panels and micro-perforated panels for sound absorption in power transmission and distribution facilities,especially for the comprehensive control of noises in substations. |
