通过对变压器固体绝缘材料主要是绝缘纸的拉伸强度与聚合度的分析
提出了变压器剩余寿命范围及可靠性预测的模型,实例结果表示可靠性预测的准确性比较高
） Abstract： Power transformers are the most important and valuable equipments for power grids at the present stage
Because many big transformers in our country have running twenty years even more long time, theirs problem of insulating aging is increasing serious
This situation becomes the major risk to threaten power grids
By the analysis being insulating paper tensile strength and polymerization degree mainly to transformer solid insulant,have brought forward transformer surplus life-span range and the model that reliability forecasts
Examples of the results of the reliability of the accuracy of the forecasts are relatively high
