摘要
分析了变电站主变压器、电抗器及散热风机等主要噪声源的发声特性及其传播属性,通过CATT-Acoustic及Cadna/A进行变电站声学模拟仿真噪声预测,综合考虑降噪效果与经济指标,提出针对规范中2类声环境区和1类声环境区噪声排放限制的达标设计方案,并提出在设计阶段优先考虑合理的平面布局、在设备购置时充分考虑低噪声的性能、设备室的吸声处理与隔声处理、通风散热通道的消声处理、门窗的隔声处理等综合治理措施。
The sound generation characteristics and propagation properties of the main noise sources such as substation main transformers,reactors and heat dissipation fans are analyzed.Noise prediction for substation acoustic simulation simulation was carried out by CATT-Acoustic and Cadna/A.Comprehensively considering the noise reduction effect and economic indicators,a design scheme for the noise emission limits of Class 2 acoustic environment area and Class 1 acoustic environmental area in the specification was proposed.Comprehensive management measures such as prioritizing reasonable layout during the design phase,fully considering low noise performance during equipment procurement,sound absorption and insulation treatment for equipment rooms,noise reduction treatment for ventilation and heat dissipation channels,and sound insulation treatment for doors and windows were proposed.
