Abstract

The invention discloses an oil-immersed type panel sound absorption and noise-lowering processing apparatus and method. The apparatus comprises multiple panel sound absorption modules; the panel sound absorption unit consists of at least one panel unit, multiple shock-absorbing units and multiple supporting units; the panel unit is a sound absorption panel and used for being coupled with sound wave in oil liquid; the shock-absorbing units are formed by shock absorber arrays and are mounted perpendicular to the panel unit and the inner side wall of an oil tank for reducing stressed vibration on the panel plane of the panel unit; the supporting units are used for supporting the panel unit to be stabilized and fixed; according to the method, a sound level meter is adopted to detect the noise of the oil tank, and the panel sound absorption modules are fixed on the corresponding inner side walls of the oil tank according to the detection result, so as to enable the panel sound absorption modules to absorb noise of power equipment; and the apparatus is low in cost and safe in material structure, and can be used for a long term in the transformer oil tank in a maintenance-free manner.

Description

technical field [0001] The invention relates to the field of environmental protection for power transmission and transformation, and more specifically, to an oil-immersed panel sound absorption and noise reduction processing device and method. Background technique [0002] Power transmission and transformation noise is the main problem of power transmission and transformation environmental pollution. A large number of actual research and tests related to power transmission and transformation noise engineering show that the body noise of oil-immersed power equipment is one of the most important sources of noise problems in power transmission and transformation projects. The noise reduction control of the submerged power equipment body has been generally recognized as the most direct and fundamental means to effectively improve the noise environment of the substation. At present, people in the relevant industry of electric power equipment at home and abroad have explored the n...
