摘要
变压器室的通风状况对变压器的安全稳定运行十分重要。对两个变压器室的运行进行了15d以上的连续监测,获得了室内外温度、油温、运行功率等数据。通过采用集中参数模型,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变压器的油温进行了模拟。
The ventilation of transformer room is very important for the safety and stability of the transformer operation.Continuous monitoring was conducted for over fifteen days with two transformer rooms.The environment and room temperatures,transformer oil temperature and operational power were recorded.A lumped-parameter model was employed to simulate the field data.The friction coefficient for ventilation and the constants of the formula for the transformer radiator were fitted.Upon these data,simulations were carried out for the transformer oil temperature under extreme summer conditions.
