Special Cooling-Fan Air Blowing Device For Power Transformer

1.Product use and characteristics
This series of Cross Flow Cooling Fan for dry-type transformers (hereinafter referred to as dry-type transformer cooling fans) are mainly used for cooling capacity expansion of dry-type transformers and cooling and cooling of electronic equipment, distribution cabinets, high and  Low Voltage Transformers and other products. The use of this series of cooling fans can increase the output power of dry-type transformers by 40-50%, which can greatly improve the bearing capacity of Dry Type Distribution Transformer and extend the service life of dry-type transformers. It is an economic and effective way commonly adopted by domestic and foreign manufacturers.
The series of dry-transition cooling fans produced by our company are optimized and designed by computer to make their air volume larger and noise lower, further improve the air pressure and reduce energy consumption. The shell of this series of dry-transition cooling fans adopts high-quality aluminum alloy profiles and stainless steel, with compact structure, beautiful appearance, easy installation and long service life, Thus, it provides a reliable guarantee for the stable operation of this series of dry-transformer cooling fans in a harsh environment for a long time.
2.Working principle
When this series of cooling fans are used for dry-type transformers, the fans are placed on both sides of the lower part of the transformer coil, and the cold air is directly blown into the high and low pressure cooling air ducts of the transformer coil. The cooling effect is obvious, which can ensure the normal operation of the transformer and extend its service life. (The functions of fan start and stop, transformer overtemperature alarm and overtemperature trip are provided by temperature control device).
