Sound-proof device for 10kV pole type transformer

Abstract

A sound-proof device for a 10kV pole type transformer comprises a support frame, a sound proof plate, transformer equipment and a fixed pillar, wherein the transformer equipment is installed on the fixed pillar; and the sound proof plate is covered on the outer side of the transformer equipment and is installed on the fixed pillar through a fixing frame. The sound-proof device has the characteristics of light structure, simplicity in construction, convenience in installation and maintenance, low cost, strong insulation performance, good sound proof effect, and integration of sound proof and insulation protection, and solves the long-existed noise nuisance problem of the pole type transformer due to the adoption of the special material and structure and the utilization of principle of cutting off sound. According to the invention, as the high-polymer material sound proof plate is adopted, and a method of cutting off the noise is adopted, the noise propagation directions and distance are both reduced. The sound-proof device has the advantages of simple processing, light weight, convenience in installation, low cost, weatherability and corrosion resistance, thereby effectively solving the attainment isolation problem of the power distribution equipment and substations. The sound-proof device is an ideal special matched device for the sound proof, noise proof, insulation and safety of the power distribution equipment and the substations.

Description

technical field [0001] The present invention relates to the noise isolation technology, and more specifically relates to a 10kV pole-mounted transformer sound isolation device for noise isolation and blocking of power distribution, power transformation and power distribution and transformation equipment. Background technique [0002] As we all know, 10kV pole-mounted transformers are likely to cause noise pollution to nearby residents due to reasons such as quality, design and construction, and maintenance; due to limitations in geographical environment, technical level, and renovation costs, it is difficult to eliminate this noise pollution. The existing 10kV pole-mounted transformer sound insulation measures are almost blank, and there is no effective means. In case of noise nuisance from distribution transformers. One is to relocate the transformer: remove the original transformer on the pole and move it to other nearby poles that do not affect the normal life of residen...
