Oil Regeneration Extends Transformer Unit Life

HOPU's mobile regeneration system restores transformer oil by removing acidity, sludge, soluble oil decay products and improves oil colour with Fuller's earth treatment technology. When the treatment is complete, the regenerated oil meets or exceeds international standards for new oil with lower acidity and improved tan delta, interfacial tension, and oxidation stability. The cellulose insulation and internal components of the transformer also benefit from the flushing effect of multiple passes of hot regenerated oil, which helps remove decay products and sludge from internal surfaces.

Advantages of Oil Regeneration

· Extends the transformer life by restoring the qualities of the transformer oil to be similar to new oil condition

· Oil Regeneration is much less costly than changing new oil

· Minimal downtime as a result no revenue loss as Oil Regeneration can be performed ‘on-inline or live’/ energized transformer

· Environmentally friendly as the existing oil is reused. There will also be no hazard from oil spills and PCB contamination, including the trouble with the disposal of old oil

· Oil Regeneration removes the sludge build up and deposited on the internal core and coils of the transformer, which a traditional oil change will not

· Oil Regeneration can be continuously performed in most weather conditions and will not run the risk of exposing the internal transformer core to adverse weather conditions during an oil change

Introduction:

ZYD-I Dielectric Transformer Oil Treatment Regeneration Machine is applied to process transformer oil and insulating oil from power plant, power station, electric power company, power transmission equipment, transformers, industrial and mining enterprises, especially suitable for on-site installation, maintenance and purifying high level new oil, or running oil from big power transmission and distribution equipment and transformers on national main power transformation grid, which is above 110-750KV. This special vacuum oil water separator can shorten the oil treatment period for transformer installation and maintenance.

Contaminants in transformer oil:
  1.Solid particles like rust scales, dust and fibres
  2.Generation of carbon particles due to ageing of switchgear
  3.Oil absorbs moisture resulting in free and dissolved water
  4.Absorption of air
  5.Aging fluids produce absorbed gases, causing equipment failure and arc suppression in switchgear
  6.Sludge formation
  7.Increase in acidity level
  8.Chemical products are caused by oxidation, as well as cross contamination of other products.

Through the vacuum dehydrator, degasification, filtration processes, the dissolved gases and moisture, solid particulate, free carbon,acid contamination can be completely removed,thus improve the oil dielectric strength,oil color,and oil quality as well.
