Description
Technical Field
[0001] This utility model relates to the field of transformer auxiliary equipment technology, specifically to a fan mounting bracket for transformers. Background Technology
[0002] Dry-type transformers are one of the most basic electrical devices in power systems. Their main function is to transform current into voltage, converting high voltage to low voltage or vice versa, to meet the needs of different electrical devices. However, due to the resistance of the core and coils of the dry-type transformer, there is energy loss when the current passes through the core and coils, which causes the dry-type transformer to generate a lot of heat during operation. The temperature of the dry-type transformer will rise, requiring timely heat dissipation.
[0003] The commonly used cooling methods for dry-type transformers mainly include natural air cooling and forced air cooling. Forced air cooling uses cooling fans to dissipate heat from the windings. Multiple fans are typically installed symmetrically below the dry-type transformer, with the fan vents pointing vertically upwards to carry away the heat generated by the transformer. However, this fan configuration does not allow for adjustment of the airflow angle. If the fans are too close to the transformer, the airflow will be blocked, making it difficult to cool the upper part of the transformer, resulting in poor cooling performance. Therefore, it is necessary to propose a fan mounting bracket for transformers that allows for adjustment of the fan's airflow angle. Utility Model Content
