Description

Technical Field

[0001] The utility model relates to a highly efficient and energy-saving transformer. Background Art

[0002] As a key component in modern power systems, highly efficient and energy-saving transformers are widely used in power transmission and distribution systems. By adopting low-loss materials, optimized designs, and advanced manufacturing processes, highly efficient and energy-saving transformers have achieved remarkable energy-saving effects. However, with the increase in the operating load of transformers, their heat dissipation problems have become increasingly prominent. A large amount of heat is generated during the operation of transformers. If the heat cannot be dissipated in a timely and effective manner, it will cause the temperature of the iron core and windings to rise, thereby affecting the performance and service life of the transformers. Currently, highly efficient and energy-saving transformers usually use heat dissipation fins welded to the transformer housing to improve the heat dissipation effect. However, the traditional heat dissipation fins have the following problems in the actual heat dissipation process: 1. The heat dissipation effect is not good, the heat dissipation is uneven, and the distribution and contact surface of the heat dissipation fins are uneven, resulting in uneven local heat dissipation, higher temperatures in some areas, and increased thermal stress on the transformer; 2. Maintenance is inconvenient. Once the welded and fixed heat dissipation fins fail or need to be cleaned, the maintenance and replacement processes are complex and time-consuming, and improvements and optimizations are made in response to this.
