| 摘 要： | 介绍了传统变压器内部热场的有限元方法模拟热路模型,并在此基础上,增加平均油温、太阳辐射等条件参数,对原有模型进行改进,利用光纤光栅温度测量系统,对变压器样机进行现场温升试验,并将热路修正模型计算结果与几台变压器实测温升数据进行对比,结果验证了该热路修正模型的精确性。

| Abstract: | Introduction was made to the ifnite element method of analog thermal circuit model of traditional transformer internal thermal ifeld, and on this basis, average oil temperature, sun radiation etc conditional parameters were added to carry out improvement for the original model. The optical ifber grating temperature measurement system was used to carry out site temperature rise test for sample transformer. This paper car-ried out comparison of thermal circuit amended model calculation result with several transformers actual tested temperature rise data. The result veriifes the correctness of the thermal circuit amended model. |
