| description | It is known that in order to restrain the process of oxidation of transformer oil,
and, accordingly, to extend its service life, an antioxidant additive ionol is added
to it. Previously, specialists using the method of chromato-mass spectrometry
established the fact of the formation of new phenolic compounds in oil along with
the consumption of the inhibitory additive ionol, namely, 2,6-di-tert-butylphenol
(2,6-DTBP) and 2, 6-di-tert-p-benzoquinone. These phenolic compounds, as well as
ionol, belong to the class of sterically hindered phenols, which, in turn, are able to
inhibit the oxidation of oil during its operation in oil-filled transformer equipment, in
particular, power transformers and current transformers. This article presents results
showing that as ionol is consumed, 2,6-di-tert-butylphenol accumulates in oil from
transformers. To the greatest extent, this trend is noticeable for current transformers
equipped with air-drying filters (the so-called "free breathing"). The formation of
2,6-DTBP in oil can serve as an indicator of accelerated aging of the oil as a result of
its prolonged contact with atmospheric oxygen. Changes in additive concentrations
during oil aging are controlled using a new technique developed by us, based on
IR spectroscopy. |
