Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a compact transformer. 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, the secondary coil and the iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. The temperature of existing transformers is too high during use, and it is necessary to set up a heat dissipation structure to dissipate heat.

[0003] Although the existing device can set cooling pipes or fans at various positions of the transformer to achieve cooling, space needs to be reserved when setting the pipes or fans, which leads to a decrease in the compactness of the transformer; the existing device cannot achieve the coordinated use of the rainproof structure and the ventilation structure through structural improvements.

[0008] Furthermore, the top surface of the cover body is provided with second through holes in a rectangular array, the second through holes are circular hole structures, and the second through holes are aligned with the top of the transformer body.

[0009] Furthermore, a shielding assembly is fixed to the top surface of the cover body, and the shielding assembly consists of a first support block and a shielding plate. A first support block is fixed to the top surface of the cover body, and a shielding plate with a square block structure is fixed to the top surface of the first support block.
