About Enclosed Transformer Oil Filtration Plant
PureTech Enclosed Vacuum Transformer Oil Filtration Plant is designed for outdoor oil filtration work of transformers, circuit breakers, oil-filled equipment and other high voltage plants. Transformer oil needs to be filtered after periodical time to ensure the dielectric strength and breakdown voltage, mainly to remove moisture content, gas content, mechanical particles, impurities, acids, oxides, etc. Even new transformer oil should be filtered before filling into transformers.
Enclosed Vacuum Transformer Oil Filtration Plant (double-stage vacuum) can also be used as an independent vacuum pumping system for evacuating the transformer for vacuum filling of oil in transformer.
The necessity of performing transformer oil filtration:
1. Transformer oil filtration plant capacities : 600 LPH ~ 18000 LPH.
2. Vacuum Stages of transformer oil filtration plant :
A. Single Stage
B. Double Stage
C. Customized option (e.g. two sets of vacuum pumping systems)
3. Filtration Stages of transformer oil filtration plant :
A. Three stages filter cartridges
B. Two stages filter cartridges
4. Regeneration function of transformer oil filtration plant :
A. without regeneration
B. with regeneration (remove acids, oxides, sulfur, and improve oil color)
5. Mounting arrangement of transformer oil filtration plant :
A. Skid
B. Trailer-mounted (single axle, two pneumatic automobile tyres and one guide wheel)
C. Trailer-mounted (double axles, four pneumatic automobile tyres and one guide wheel)
5. Operating modes of transformer oil filtration plant :
A. Manually control type
B. Automatic control type with PLC and HMI screen
Performance of Transformer Oil Filtration Plant
• Improvement of transformer oil dielectric strength breakdown voltage from 20 KV to above 75 KV.
• Removal of moisture from 100 ppm to below 5 ppm after vacuum dehydration.
• Removal of gases from 10% to below 0.1% after vacuum degassing.
• Filtering capacity: Max. particle size less than 1~5 micron in the filtered oil, 3-stages filtering elements.
