Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a dust removal structure. 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 (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] When the transformer is working, it uses the heat sink on its surface to cool down. However, when the transformer is outdoors for a long time, a large amount of dust will adhere to the heat sink and the surface of the insulator, which will affect the heat dissipation of the transformer and the insulation performance of the insulator. The traditional way to remove dust from the transformer is to use a high-pressure water gun or air gun to flush it. Although this method can remove dust from the transformer, it is necessary to flush the transformer one by one along the four sides when flushing the dust. When flushing multiple transformers or large transformers, the efficiency will be slow, and the dust cannot be quickly removed from the surface. In response to the above defects: To this end, we propose a transformer with a dust removal structure. Utility Model Content
