Cooling Fan for Dry-Type Transformer, Accessories for Transformer
Cooling fans or dry-type transformer's heat dispersion.
It's one of the most important optional accessories for dry-type transformer.
1. Under normal conditions, the output of the transformer can be exceed 40%~50% of the rated capacity in the state of air forced cooling (AF) . It can be applied in the condition of sudden overload or discontinuous overload. Due to the large increase of load loss and impedance voltage , continuous over load operation with AF for long time is not recommended.
2. For transformer with AN and AF cooling methods, good ventilation capacity of transformer enclosure should be guaranteed. When the transformer is placed in basement and other places with ill-ventilation, ventilating instrument should be equipped, and the air flow rate is selected according to 2~4 m³/min per 1kW loss( P0+Pk). The quantity and power of the cooling fans are given in the chart below.
Quantity x Power
1) The standard power supply of the fans is AC 220V or 380V
2) The dimension of air forced cooling system (cooling fan) can't surpass the dimension of the transformer.
