Problems solved by technology

[0003] The structural design of the traditional transformer is relatively simple. Due to the lack of corresponding sound insulation and noise reduction design, the transformer will generate a lot of noise in the actual operation process, and the surface insulation performance of the transformer is average, and there are certain safety hazards, so there are certain risks. limitation

Abstract

The invention belongs to the technical field of transformers, particularly relates to a noise reduction insulation transformer. Aiming at the problems that a traditional transformer is simpler in structural design, the transformer generates larger noise in the actual operation process, the surface insulation performance of the transformer is common, and certain potential safety hazards exist. thenoise reduction insulation transformer of the scheme comprises a shell, a rubber outer layer is fixedly installed on the outer wall of the shell, a foaming inner plate is fixedly installed on the inner wall of the shell, and the side, opposite to the shell, of the foaming inner plate is filled with a sound insulation cotton layer. Through the arrangement of the sound insulation cotton layer and the foaming inner plate, the sound absorption and noise reduction effects of the transformer can be effectively improved; through the arrangement of the rubber outer layer, the transformer can have goodinsulativity, and the safety performance of the device is improved; an annular groove is provided with multiple air inlet groove openings communicated with the outside, natural air can enter the annular groove, and a good heat dissipation effect is achieved under the heat exchange effect of the heat exchange columns.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a noise reduction insulation transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage of a certain value into another voltage with the same frequency or several different values. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. In short, both step-up and step-down must be completed by transformers; in the process of transmitting electric energy in the power system, there...
