摘要:
为了分析油浸式电力变压器内部油流场与热源温度分布的关系,将实物模型合理简化为2D模型,利用有限元思想划分网格,将模型离散化.合理设置了边界条件及初始条件.通过Fluent求解了变压器内部的温度场和流场.得到内部温度与流动形态的分布.结果表明,油流速度对箱内温度分布有一定影响,但合理的流速分布才能更多的带走热量,并不是越快或者较慢越好.这为变压器结构的设计与材料的选用提出建议.
Abstract:
To analyze the relationship between internal oil flow field and heat source temperature distribution of oil immersed power transformers, the physical model was reasonably reduced to a 2D model and discretized by dividing grids using finite element method. Reasonable boundary conditions and initial conditions were set. Then, the temperature field and flow field of the transformer were solved using Fluent, and the distribution of internal temperature and flow pattern was thus calculated. The results show that flow velocity has a certain effect on temperature distribution, but it is the distribution of reasonable flow rate that can take away heat more quickly. It is not the case that the faster, the better, or the slower, the better. This can shed light on how to design transformer structure and select materials.
