Product Outline

 GF series cross-flow cooling fan for top-blown dry-type transformer (hereinafter referred to as: dry transformer cross flow cooling fan) is mainly used for dry-type transformer cooling capacity increase, and electronic equipment, distribution cabinets, high and low voltage switchgear and other forced air cooling. The capacity of dry-type transformer can be increased by 40 ~ 50% after heat dissipation by the fan, thus greatly improving the bearing capacity of the dry-type transformer and prolonging the service life of the dry-type transformer, it is an economical and effective method widely adopted by manufacturers at home and abroad. This product strictly according to JB/T8971-1999“Dry-type transformer with cross-flow cooling fan” design and production. The stator and rotor cores of the motor are made of cold-rolled silicon steel sheets; low-noise bearings; the impeller surface is electrophoretic treated with aluminum alloy and fine dynamic balance adjustment; the left and right end plates are made of stainless steel plates, the air inlet plate, the air outlet plate and the air guide plate are made of aluminum alloy, the utility model has the advantages of large air volume, small noise, low temperature rise, long service life, stable operation, convenient installation, etc. . 

Working principle

When the series cooling fan is used in dry-type transformer, the fan is 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 channel of the transformer coil, the heat dissipation effect is obvious, the utility model can ensure the normal operation of the transformer and extend its service life. The functions of fan on, off and transformer over-temperature alarm and over-temperature tripping are provided by temperature control device.
