Abstract:

Abstract: This paper described the characteristics, major noise source, noise intensity, frequency characteristics of the 220kV indoor substation. It analyzed the noise propagation of the 220kV indoor substation. Systematically analyzed the noise control measures of the 220kV indoor substation, and briefly described an engineering example, which can be reference to the same project.

摘要：

通过对多个220 kV室内变电站的调研和噪声测试分析，论述220 kV室内变电站的特点、主要噪声源、噪声源的源强、频率特性，剖析其噪声传播影响，对220 kV室内变电站的噪声控制措施进行比较分析，并简要介绍一个工程实例，可供同类工程参考。
