Problems solved by technology
[0003] However, there are some deficiencies in the dry-type transformers at this stage. The bladeless cooling fans of the dry-type transformers cannot adjust the air outlet angle of the wind protection net, and cannot effectively cool the dry-type transformers. Dry-type transformers with higher temperatures will affect Its function cannot be played, and a dry-type transformer that has been in a high temperature state for a long time will damage the internal components

The invention discloses a dry-type transformer equipped with a bladeless cooling fan device. The transformer comprises a dry-type transformer bank body and a supporting base, the supporting base is fixedly connected to the lower surface of the dry-type transformer bank body, rollers are fixedly connected to the positions, close to the four corners, of the surface of the supporting base, the upper surface of the dry-type transformer bank body is fixedly connected with an upper iron yoke, the upper surface of the upper iron yoke is fixedly connected with a high-voltage upper clamping cover, the front end and the rear end of the dry-type transformer bank body are located on the upper surface of the supporting base and movably connected with turning covers, the upper surface of each turning cover is fixedly connected with a bladeless cooling fan, and the front end face and the rear end face of the dry-type transformer bank body are fixedly connected with winding rocker devices. According to the dry-type transformer equipped with the bladeless cooling fan device, the dry-type transformer bank body can be cooled by effectively utilizing air blown out by the bladeless cooling fan.
Description
technical field [0001] The invention relates to the field of dry-type transformers, in particular to a dry-type transformer equipped with a bladeless cooling fan device. 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. The cooling methods are divided into natural air cooling and Forced air cooling, under natural air cooling, the transformer can run continuously at the rated capacity for a long time, and under 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. Since the load loss and impedance voltage increase greatly during overload, it is in a non-economic operation state, so it should not be used for long-term con...
