Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer assembly. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is one of the core equipment for power transmission and conversion. In the power system, the transformer has functions such as voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. It is the basic equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities and other fields. Existing transformers lack heat dissipation devices, and in actual practice, the transformer is prone to overheating, resulting in a decrease in efficiency.

[0003] The Chinese patent discloses an oil-immersed transformer (authorization announcement number CN222028911U). The patented technology is provided with an upper heat-conducting copper column and a lower heat-conducting copper column and a plate-type heat sink assembly. The upper heat-conducting copper column and the lower heat-conducting copper column are respectively connected to the plate-type heat sink assembly and the inside of the transformer box, and an upper connecting groove and a lower connecting groove are provided at the top and bottom of the plate-type heat sink assembly. The upper heat-conducting copper column and the lower heat-conducting copper column are fitted and connected with the upper connecting groove and the lower connecting groove, thereby increasing the contact area and effectively realizing the heat dissipation function; by providing a groove on the heat sink closest to the transformer box in the plate-type heat sink assembly, the upper heat-conducting copper column is fitted and connected with the groove, thereby increasing the connection area between the upper heat-conducting copper column and the plate-type heat sink assembly, further improving the heat dissipation effect;
