Title:
SOUND BARRIER SYSTEM FOR REDUCING ELECTRIC FIELD DISTORTION AND METHOD FOR IMPROVING SOUND ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2023/185892
Kind Code:
A1
Abstract:
A sound barrier system for reducing electric field distortion, comprising a wall unit and a sound barrier unit. An upper side portion of the sound barrier unit is an arc-shaped sound barrier plate, the center of the arc thereof points to the interior of an electric power facility, and the side surface of a lower side portion of the arc-shaped sound barrier plate is attached to the side surface of an upper side portion of a sound absorption layer; the sound barrier unit is provided at the top of the wall unit; the arc-shaped sound barrier plate is provided at the top end of the wall unit; the sound absorption layer is provided on the side surface of the inner side of the wall unit; the sound absorption layer is flush with the inner side of the wall unit; a sound barrier further comprises an energy supply pipeline, a security and protection device and an online monitoring device. The sound barrier system of the present invention is convenient to manufacture, can improve the sound environment around a transformer substation, and can reduce an electric field amplitude at the top of the sound barrier system to 80% of an electric field amplitude at the top of a conventional type of sound barrier system. Moreover, the sound barrier unit comprises a sound barrier plate design having an arc-shaped part, so that the wind load resistance of the system is enhanced; in addition, the energy supply facility is provided for the sound environment online monitoring device, so that the working stability of the online monitoring device is improved.
