TAD Transformer Dry Air Generator Plant
ASSEN TAD Dry Air Generator Plant can provide air drying circulation inside the transformer, replacing the traditional hot oil circulation method. It is suitable for the supply of dry air during the overhaul of large-scale power transformers.
TAD dry air generator machine is suitable for supplying dry air at site and is able to be continuously operated without manual assistance by automatic recycling of air drying and regeneration of adsorbent
Supplying dry air that keeps the power equipment's inner parts from moisture in the maintenance of the transformer, reactor and other large power equipment.
ASSEN TAD Dry Air Generator Plantis mainly regenerating dry air with low dew point when installing or repairing equipment such as transformers and reactors. The dry air it provides ensures that the internal insulation of the electrical equipment does not get wet, and the worker does not suffocate due to a lack of oxygen while working inside the equipment. Compare to using nitrogen, dry air is safer, more reliable, better economical, and convenient.
The dry air can ensure that the internal insulation of the power equipment will not be affected by moisture, and maintenance workers will not suffer from oxygen deficiency when working inside the equipment. It is safer, more reliable, economical, and convenient than using nitrogen.
With the help of a dry air generator, transformer overhaul can be performed day and night, regardless of the weather condition. The air drying system also shortens the maintenance schedule, improves the quality of inspection result
With advanced PLC control, the equipment can supply dry air at the site and is able to work continuously without manual assistance.
1. Remove moisture from the air. The dew point limit of the treated air can be below -80 °C.
2. Remove particulate matter from the air.
3. When the transformer works overnight, Instead of nitrogen-filled or hot oil circulating dryness
4. Dry air is supplied during transformer installation and maintenance to ensure dryness inside the transformer.
5. The cylinder is filled with dry air.
TAD Dry Air Generator's Flow Chart
When using the dry air generator for equipment maintenance, it is not affected by changes in external climatic conditions; especially for overnight operation, it is only necessary to seal the flanges and fill the dry air to 0.02MPa~0.03MPa.
The lower the air dew point, the less water in the air and the drier the gas equipment. When the atmospheric dew point is 20℃, the water content in the air is 17.8 g/m³ ; when the atmospheric dew point is -70℃, the water content in the air is 0.005 g/m³
