Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a high-efficiency transformer noise reducer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. The transformer is an important part of the power grid. Ensuring the safe and reliable operation of power transformers is related to all aspects of production and life and has important social significance.

[0003] There are still some problems in the use of existing transformers: when the transformer is working, it will generate buzzing noise due to vibration, affecting the lives of residents. Nowadays, most of the noise is reduced by using silencers, but silencers are installed around the transformer. However, due to the good sealing effect, it is not easy to disassemble, which will not only affect the heat dissipation of the transformer, but also increase the workload of transformer maintenance personnel, affecting the maintenance of the transformer. In addition, a large amount of heat is easily accumulated inside the transformer when it is working, which may easily cause damage to the internal components of the transformer over time and affect the service life of the transformer. In view of the above problems, the inventor proposes a high-efficiency transformer noise reducer to solve the above problems. Utility Model Content
