摘要
建立了一台500 k V超高压油浸式变压器的二维模型,基于ANSYS Fluent软件,采用Laminar层流模型对其进行二维定常层流计算,获得了变压器温度场分布及热点位置,并研究了绕组端部角环位置对变压器油热性能的影响。经过实际对比发现,计算结果和相关试验值吻合很好,从而为今后超高压变压器的设计、研发和试验提供了重要依据,这表明利用Fluent软件对超高压变压器的数值计算和性能分析可以应用于工程实践中。
A 2D model of 500 kV ultra-high voltage oil-immersed transformer is built. The two-dimensional steady laminar flow in the model is simulated using the Laminar model based on the software Ansys Fluent, and the temperature distributions and the position of hot spot within the transformer are obtained.The position effect of the angle rings at winding end on the thermal property of oil is analyzed. Simulation results are consistent with the experimental ones, which infers that the numerical simulation method on the basis of ANSYS Fluent is applicable to temperature field analysis of ultra-high voltage transformers. This study may provide a tool for design, research and development, and test of ultra-high voltage transformers.
