摘要： A contribution identification method for noise at a boundary of an urban substation in the present disclosure includes the following steps: describing site elements and surrounding environmental elements of an urban substation; measuring and recording a background noise value at each boundary of the urban substation; determining an orientation of a specific sound source of the urban substation, and setting a corresponding measurement point at each boundary of the urban substation; obtaining a spectrum of each specific sound source; analyzing a contribution of each intra-substation sound source of the urban substation to noise at the boundary of the substation; analyzing a noise level of each sound source measurement point in the urban substation; recording measured data during noise measurement, and correcting a noise measurement result; and generating a test report.

摘要： A sound barrier system for reducing electric field distortion includes a wall unit and a sound barrier unit. The sound barrier unit includes a sound barrier plate that, from top to bottom, includes an arc-shaped part, an inclined part, and a vertical part that are integrally formed, wherein a center of a circle of the arc-shaped part points towards an interior of a power facility, the inclined part is tilted away from the power facility from top to bottom and is tangent to the arc-shaped part, and a lower end of the vertical part is arranged on a top of the wall unit. The sound barrier system further includes an energy supply pipeline, a security device, and an online monitoring device. The sound barrier system can be easily manufactured, and not only can improve an acoustic environment around a substation, but also can reduce an amplitude of an electric field.
