The invention relates to an outdoor electrical equipment box body and noise reduction method thereof, and is used for reducing noise of a body of outdoor electrical equipment. The box body includes a main body unit used for accommodating outdoor electrical equipment; a plurality of reinforcing ribs located on the outer surface of the box body main body unit and used for reinforcing the main body unit; and a plurality of noise reduction units used for performing noise reduction treatment on the outdoor electrical equipment, wherein each noise reduction unit is a sound guiding pipe, and includes a first connecting pipe and a second expansion connecting pipe, the first connecting pipe is a hollow cuboid, the bottom surface of the second expansion connecting pipe is equal to that of the first connecting pipe, a plane having expansion characteristics is away from the outer surface of the main body unit, the noise reduction units are installed between adjacent vertical reinforcing ribs on the outer surface of the main body unit, the second expansion connecting pipe is located at the upper part of the box body main body unit, and the first connecting pipe is located at the lower part of the box body main body unit.
Description
technical field [0001] The invention relates to the field of environmental protection for power transmission and transformation, and more particularly, relates to an outdoor power equipment box and a noise reduction method thereof. Background technique [0002] A large number of actual research tests related to power transmission and transformation noise engineering have shown 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. It has been generally considered that the noise reduction control of oil-immersed power equipment It is the most direct and fundamental means to effectively improve the noise environment of substations. Power equipment related industries at home and abroad have explored a variety of technical measures to reduce the noise of transformers, but most of them are limited by factors such as cost, heat dissipation, and maintenance. The cost of various ex...
