AC TRANSFORMER COOLING FAN
Product features and uses
LWF series cross flow cooling fan for dry-type transformer (hereinafter referred to as dry transformer cooling fan) is mainly used for dry-type transformer The cooling capacity and cooling of electronic equipment,distribution cabinet, high and low voltage switch cabinet and other products. The output power of dry-type transformer can be increased by 40 ~ 50% by using this series of cooling fans,so that the dry-type transformer can be greatly improved lt is widely used by domestic and foreign manufacturers for its bearing capacity and extended service life the most cost-effective way.
Working Principle
When GF series cooling fan is used in dry-type transformer, the fan is placed on both sides of the lower part of transformer coil to cool down. The wind is directly blown into the high and low pressure cooling air ducts of the transformer coil, and the heat dissipation effect is obvious, which can ensure the transformer's Normal operation and extended service life. (the functions of fan start-up and shutdown，over temperature alarm and over temperature trip of transformer are provided by temperature control device.)
