摘要 为研究电力变压器油纸绝缘在热、电两种应力作用下的老化特性,搭建了油纸绝缘热电联合老化试验平台,设计了两组在130℃下进行的加速老化试验：一组是单因子热老化试验,另一组为热电联合老化试验。通过对两组老化样本的绝缘纸聚合度、击穿电压、油中微水含量等参数进行对比分析,结果表明,热电联合老化样本绝缘纸聚合度下降速度比热老化样本要快,且在老化初期绝缘纸击穿电压与绝缘纸聚合度呈一定线性关系,与油中水分含量则没有明显的直接联系。

Abstract：In order to study on thermo-electrical aging of transformer oil-paper insulation, a test platform for thermo-electrical aging of oil-paper insulation is set up, and two groups of accelerated aging test are designed under 130℃. One is thermal aging test, the other is thermo-electrical aging test. By the comparison of two aging tests, the result shows that DP of paper under thermo-electrical stress decreases faster than that under single thermal stress. The breakdown voltage of paper has a linear relation with DP but no significant relationship with water content in oil at the beginning of the aging progress.
Key words： power transformer    oil-paper insulation    thermo-electrical aging    breakdown voltage
