摘要(Abstract)：

通过对两个运行的变压器室进行15天以上的连续监测,获得了室内外温度、油温、运行功率等数据。采用集中参数模型对这些现场数据进行了拟合,得到了变压器室通风阻力系数和变压器散热公式中的常数。在此基础上,对夏季极端环境条件下的变压器油温进行了模拟。
Continuous monitoring for two transformer rooms in operation was conducted for over fifteen days.The environmental and room temperatures,transformer oil temperature and operational power were recorded.Through the simulation of the field data with a lumped-parameter model,the friction coefficient of ventilation and the constants of the formula for the transformer radiator were obtained.On that basis,simulations were carried out for the transformer oil temperature under extreme summer conditions.
