摘要
建立了分体式冷却变压器顶层油温热路计算模型,根据实测数据和搜索算法对热路模型的热参数进行拟合求取,实例验证并与传统变压器简化的热路计算法和负载导则中的微分方程解法对比分析。
The thermal circuit calculation model of top temperature of split-type transformer is established. Thermal parameters of the calculation model are solved according to the measured data by searching algorithm. Verification of examples is carried on,comparison and analysis with traditional transformer simplified thermal circuit method and differential equation method in the loading guide are studied.
