Transformer Oil Cooler

Transformer Oil Cooler

Transformer oil cooler is a kind of equipment used to cool transformer oil.

Working Principle

Transformer in the process of operation will produce heat, the heat if not timely emitted, will lead to transformer temperature rises, affecting its normal operation. Transformer oil cooler through the circulating flow of cooling medium (usually water or air) and transformer oil for heat exchange, the transformer oil heat away, so as to reduce the temperature of the transformer.

Types

Water cooler: using water as cooling medium, the heat of transformer oil is transferred to water through heat exchange. Water cooler is usually composed of cooling water pipe, radiator and oil pump. Water cooler has the advantages of good cooling effect, small footprint, but requires regular maintenance and cleaning to prevent scale and corrosion.

Air cooler: using air as the cooling medium, through the fan will air blowing through the radiator, the heat of the transformer oil away. Air cooler has the advantages of simple structure, easy maintenance, but the cooling effect is relatively poor, suitable for small transformers or ambient temperature is low.

Importance

Ensure the normal operation of the transformer: transformer oil cooler can effectively reduce the temperature of the transformer to ensure that the transformer operates within the normal temperature range, prolonging the service life of the transformer.

Improve the capacity of the transformer: by reducing the temperature of the transformer, the capacity of the transformer can be increased, so that it can withstand greater loads.

Protect the insulation of transformer: transformer oil cooler can keep the temperature of transformer oil in the appropriate range, prevent the transformer oil from overheating and damaging the insulation, so as to protect the safe operation of the transformer.
