Transformer cooling

With the gradual increase of temperature, the cooling of Transformer becomes more and more important. Then how to use it quickly cooling, Zhenhua small for your professional guidance.

The cooling method of transformer is decided by cooling medium and circulation method.

1. The cooling methods of dry-type transformer are divided into natural air cooling (an) and forced air cooling (AF);

2. The common cooling methods of oil immersed transformer are generally divided into three types: oil immersed self cooling type, oil immersed air cooling type and forced oil circulation.

Features of oil immersed transformer cooling method are introduced

1. Oil immersed self cooling type is to take heat to the tank wall and heat pipe by natural convection of oil, and then dissipate heat by convection conduction of air. It has no special cooling equipment.

2. The oil immersed air cooling type is based on the oil immersed self cooling type. An electric fan is installed on the oil tank wall or heat dissipation tube, and a blower is used to help cooling. The capacity of the transformer can be increased by 30% ～ 35%.

3. Forced oil circulation cooling method is divided into forced oil air cooling and forced oil water cooling. It is to pump the oil in the transformer into the oil cooler and then return to the oil tank. The oil cooler is made into a special shape of simple heat dissipation. The electric fan or circulating water is used as the cooling medium to take away the heat. If the circulating speed of oil is increased 3 times than that of natural convection, the capacity of transformer can be increased by 30%
