Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a heat dissipation structure of a power transformer. Background Art

[0002] A power transformer is a static electrical device used to convert a certain AC voltage into another or several different voltages of the same frequency. Power transformers can not only be adjusted according to the load of the power system to achieve power balance in different areas, but also provide safety protection for the power system, preventing abnormal power conditions from affecting the entire system. However, the temperature of the power transformer will continue to rise during long-term use, which may cause the power transformer to malfunction. Therefore, a heat dissipation structure is needed to reduce the internal temperature and provide certain protection. For example, a Chinese patent application number: CN202320281019.2 discloses a heat dissipation structure for an underground power transformer. The structure fixes the side plates to the power transformer with bolts, and uses aluminum heat sinks fixed at equal intervals inside the frame to conduct heat to the interior of the power transformer. The aluminum heat sinks are cooled by a cooling fan. However, when the device malfunctions and the cooling mechanism needs to be repaired, the bolts need to be removed, which is not convenient. In addition, heat can only be dissipated by the cooling fan, and the heat dissipation area is limited, which cannot be quickly cooled. When the body temperature is too high, timely heat dissipation may not be achieved. Utility Model Content
