Using Orbicular Silica Gel to Deal with the Matter of Abnormal Moisture Medium Wastage Factor in Transformer Oil

摘要

Examining the certain famous Italian Company's transformer whose oil brand No. was AGIP and used for two or three years, we found that tgδ (90℃) was disqualification and moisture content went beyond the standard by the oiliness examination. Moreover, vacuum filter oil machine is nullity for dehydration. Through analyzing, oil dissolved such carbonyl compound. Such an orbicular silica gel could adsorb tg5 and moisture, which could reach the standard. Therefore, concentrating on the reasons of this matter, I will do such analysis as follows.
