摘要
The noise generated by various electrical equipment in the operation of substation will inevitably directly affect the surrounding residents and environment, which becomes an important problem to be solved. Taking the main noise source transformer of 110 kV substation as an example, the transformer is modeled as a six-plate closed box structure. The sound field radiated by a flat plate is studied by using the corresponding boundary conditions and excitation frequency. By using the equivalent point source in the center of the plate, the radiated sound field of the plate is compared with that of the equivalent point source. Through the modal analysis and harmonic response analysis of the plate, the acoustic radiation characteristics of the plate under the natural frequency are obtained. The acoustic radiation pattern of different distance field points is selected for the plate, and the acoustic radiation direction characteristics of different distance are obtained, so that the transformer can be equivalent to a point source only under certain structural modal characteristics.
