Abstract

The changes in physicochemical parameters such as specific resistance, viscosity, density, and formation of gaseous products H₂, CH₄, C₂H₄, C₂H₆, C₃H₈, C₄H₁₀, C₅H₁₂, and C₆H₁₄ with respect to the adsorbed dose in the interval of 29.7–237.6 kGy are studied. It is established that the chemical composition of transformer oil changes under the action of γ irradiation, which is accompanied by the changes in specific resistance, viscosity, and density of oil. The degree of conversion depends on the adsorbed dose and grows when it increases. The IR spectra show =C–H stretching vibrations, –C=C in-plane deformation vibrations, and –CH out-of-plane deformation vibrations of aromatic compounds. In addition, there are –C–H stretching vibrations and antisymmetric and symmetric –C–CH₃ deformation vibrations in alkanes. The IR absorption spectra are observed in the range of Δλ₁ = 2800–3300 cm^–1, Δλ₂ = 2000 cm^–1, Δλ₃ = 1350–1450 cm^–1, and Δλ₄ = 600–1200 cm^–1. The absorption band of Δλ₄ = 600–1200 cm^–1 is a smeared part of the spectrum with a number of weak absorption bands.

电离辐射作用下变压器油的工作特性变化

摘要

物理化学参数的变化，例如电阻率，粘度，密度和气态产物H ₂，CH ₄，C ₂ H ₄，C ₂ H ₆，C ₃ H ₈，C ₄ H ₁₀，C ₅ H _12的形成，和C ₆ H ₁₄关于在29.7-237.6 kGy范围内的吸附剂量的研究。可以确定，变压器油的化学成分在γ射线的作用下发生变化，并伴随着油的比电阻，粘度和密度的变化。转化程度取决于吸附剂量，并随其增加而增长。红外光谱显示= C–H拉伸振动，–C = C平面内形变振动和–CH平面外芳族化合物形变振动。此外，烷烃中存在–C–H伸缩振动以及反对称和对称–C–CH ₃变形振动。红外吸收光谱中的Δλ范围内观察到₁ = 2800-3300厘米^-1，Δλ ₂ = 2000厘米^-1，Δλ ₃ =一三五〇年至1450年厘米^-1，和Δλ ₄ = 600-1200厘米^-1。的Δλ的吸收带₄ = 600-1200厘米^-1是具有多个弱吸收带的光谱的的拖尾部分。
