Dry Type Transformer Cooling Fan refers to the device used for transformer cooling. It is designed and produced in strict accordance with JB/T8971-1999 Crossflow Cooling Fans for Dry-type Transformers. The iron core of the motor stator and the rotor is made of high-quality cold-rolled silicon steel sheet with low noise bearing. The impeller adopts aluminum alloy surface electrophoresis treatment and then fine dynamic balance adjustment. The left and right end plates are made of stainless steel by stamping, and the air inlet plate, air outlet plate, and air guide plate are made of aluminum alloy profiles by buckle combination. The fan has a reasonable structure, beautiful appearance, large air volume, torann íseal, ardú teocht íseal, saol seirbhíse fada, stable operation, convenient installation, srl.

working principle

When the cooling fan is used for the dry-type transformer, it is placed on both sides of the lower part of the transformer coil to blow the cold air directly into the high and low-voltage cooling air ducts of the transformer coil, with a noticeable heat dissipation effect, which can ensure the regular operation of the transformer and extend its service life. (The cooling fans startup and shutdown, transformer overtemperature alarm, and overtemperature trip are provided by temperature control device).

Model description

Mar shampla, the fan model is GFDD470-120A, which means that the working voltage is single-phase 220V, the total length of the fan is 470mm, and the impeller diameter is 120mm. The top-blowing dry-type transformer with the motor installed on the right side uses the Cross Flow Cooling Fan.

Cooling mode

There are two cooling methods for dry-type transformers, namely natural air cooling (AN) and forced air cooling (AF).In a natural air-cooled environment, transformers can operate continuously for a long time at a lower capacity. Under forced air cooling conditions, the output capacity of the transformer can be increased by 50%. It applies to intermittent overload or emergency overload operations. Due to the significant increase of load loss and impedance voltage during overload, it is in a noneconomic operation state, so it should not be in a long-term continuous overload operation.
