Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a high-efficiency silent transformer. Background Art

[0002] Transformers are key power transmission and conversion equipment in power systems and are widely used in power, industrial control, and civil applications. As industry and society increase their requirements for power equipment efficiency and environmental protection, some problems in the operation of traditional transformers have gradually attracted attention, including low heat dissipation efficiency, high noise, high energy loss, and short equipment life.

[0003] At present, conventional transformers generally use ordinary silicon steel sheets as core materials. Their designs often have problems such as insufficient structural compactness and high eddy current losses, which lead to severe heating of the core and uneven heat dissipation, thus affecting the operating efficiency and reliability of the transformer. In addition, since the core and windings generate vibration and electromagnetic noise during operation, conventional transformers often make a lot of noise during operation, making it difficult to meet the requirements for silent operation in modern industrial equipment and residential areas.

[0004] On the other hand, the cooling system design of the transformer also directly affects the performance and life of the equipment. Traditional cooling designs mostly rely on a single fan or a simple ventilation structure, which has limited cooling efficiency and is prone to generate loud noise during air flow. In addition, with the diversification of the use environment, the requirements for heat resistance, corrosion resistance and long-term operation stability of the transformer are also constantly increasing. However, in the existing technology, the overall design scheme for improving heat dissipation performance, reducing noise and increasing equipment life still has certain shortcomings.
