Solve the excessive use of transformer oil dielectric loss in two ways: one is the replacement of substandard oil, re-injection by electrical test and chemical analysis of the indicators are qualified oil; the other is the excessive oil recycling process.
1 replace the failed oil.
Replacement of substandard oil can reduce system outage time, the net just put the old oil inside the transformer, the transformer oil with a qualified rinse, and then the transformer vacuum oil purifier. This treatment is more suitable for the unit does not allow an extended power outage; unit operation for a long time, the higher the value of oleic acid, dark yellow or brown oil, or oil-free water appear cloudy phenomenon, and overall degradation of the situation. But the simple transformer oil filtering oil as a "wash" thorough and oil-consuming, it is not conducive to energy conservation and environmental protection, excessive oil should not be the first choice for oil processing.
2 regeneration process.
Regeneration process is the physical-chemical or chemical methods to remove harmful substances in the oil, restore or improve the physical and chemical indicators of oil. Regeneration process commonly used methods are: a white absorbent indigenous law and sulfuric acid. Sorbent method for dealing with degraded to a lesser extent oil; sulfuric acid treatment for white indigenous degradation of heavy oil. Sorbent method can be divided into contact with law and the percolation method, the contact law using powdered adsorbents (such as clay, 801 adsorbents, etc.) and exposure to oil in the mixing mode of regeneration; the filtration method with which to force the oil through the granular adsorbent (eg silica gel, activated alumina, and clay particles, etc.) purification, the leachate recycling processing. For more serious deterioration of transformer oil, white indigenous sulfuric acid can be used for regeneration treatment. Sulfuric acid to remove the oil in a variety of aging products, clay treatment can eliminate the residual acid in the oil bad thing. In the actual production and operation, often encountered in oil by vacuum filtration and purification treatment, oil water content is small, the oil dielectric loss due to the higher value, and this is because the oil is not only the number of dielectric loss with water, but also with a number of factors related.
From the above analysis can be found, most of the transformer oil dielectric loss factor increases because the oil soluble polar substances (such as sol, etc.) due to the increase. For the sol particles having a diameter of 10-gm ~ 10-Tm between, through the filter paper, therefore, the two vacuum oil filter processing can not achieve its purpose of dielectric loss factor, so by this process causes the oil dielectric loss factor increasing problem, usually filtration assay regeneration treatment can get good results.
