对3种不同微水含量的FR3?型天然酯绝缘油试样进行加速热老化试验,并与同等条件下的矿物绝缘油进行老化对比试验,分析两种油中溶解气体随老化时间的变化情况。结果表明:在同等条件下,天然酯绝缘油老化过程产生气体的速率和含量均远高于矿物油的;微水含量为50~2μL/L时,微水含量的差异对老化产气的影响可忽略;绝缘油表面氧气氛围的存在对天然酯老化产气的影响比较大,有氧气存在时,相同老化时间内油中溶解的氢气、二氧化碳、甲烷、乙烷、乙烯的含量均升高,而一氧化碳含量则降低。

Three FR3? natural ester insulating oil samples with different micro water contents were conducted accelerated thermal ageing test, and the mineral insulating oil was conducted ageing test under the same condition to comparison. The change of dissolved gas in the two kinds of oils with ageing time were analyzed. The results show that the production rate and content of dissolved gas in the natural ester insulating oil are much higher than that in the mineral insulating oil under the same ageing condition. The effect of micro water content difference on the gas production during ageing can be ignored when the micro water content is between 50 μL/L and 200 μL/L. The effect of oxygen on the gas production of natural ester during ageing is big. When there exist oxygen, the contents of dissolved H2, CO2, CH4, C2H6, and C2H4 in the natural ester increase, and the CO content reduces in the same ageing time.
