摘要
对一个电缆变压器的绕组,通过求解有限元方程,得到其温度场和热气流场的分布。在此基础上,建立其分布参数的热路模型。利用该模型经修正后求解了不同负载条件下绕组的温度分布,并将有限元法计算值和实测值进行了比较,证明了模型的正确性。这种方法为研究该类变压器的温度特性提供了方便。
In this paper,the distributions of the temperature and flow field are derived for a cable transformer coil by solving the finite element equations.Based on this,the thermal circuit model with distribution parameters is built up.The temperature distribution is provided by using this model corresponding to various loads.The model is also proved to be valid through the comparison between the calculation results and the measurement results.The study provides a feasible way to investigate the temperature characteristics for the cable transformer.
