Problems solved by technology
[0004] When the existing dry-type transformer is used, the moisture-proof effect is poor. For example, if it is in the air with high humidity for a long time, it will affect the service life of the entire dry-type transformer. Even damaged, use reliability is low
And when the dry-type transformer is used outdoors, the heat dissipation effect cannot be guaranteed. If the temperature is too high, it is easy to burn the dry-type transformer

The invention discloses a moisture-proof dry-type transformer with breathable heat dissipation, belonging to the field of transformers. A moisture-proof dry-type transformer with breathable heat dissipation comprises a bracket, the bracket includes a fixed shell, and the upper and lower ends of the fixed shell are fixedly connected with a pair of positioning The fixed shell is slidably connected with three transformer main bodies, the positioning column is fixedly connected with a floating seat matching the transformer main body, the outer side of the transformer main body is fixedly connected with a casing, the floating seat includes a fixing ring, a fixing ring There is a floating ring connected to the upper rotation, a servo motor matching the floating ring is fixedly connected in the fixed ring, and a driving wheel matching the floating ring is fixedly connected to the power output end of the servo motor, which can ensure the air permeability and heat dissipation of the high-voltage device. In addition, the device can selectively ventilate according to the external humidity. When the ambient humidity is high, the device is closed to ensure that the device is completely sealed and effectively prevent external water vapor from infiltrating into the main body of the transformer.
Description
technical field [0001] The invention relates to the field of transformers, more specifically, to a moisture-proof dry-type transformer with breathing heat dissipation. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. [0003] Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be used f...
