摘要
通过对标准中冷却曲线数值外推法的分析,研究了干式变压器温升试验中数值外推法的适用性,并结合对温升试验问题实例的探讨,得到了一种适合于干式变压器温升试验的包含补充方法的数值外推法。
The applicability of the numerical extrapolation procedure in the temperature rise test of dry-type transformers is studied by analyzing the numerical extrapolation procedure of the cooling curve provided by standard.Combined with the discussion of some example of temperature rise test,a numerical extrapolation procedure including supplementary method suitable for temperature rise test of dry-type transformer is obtained.
