摘要:
绕组热问题的研究涉及到电磁学、流体动力学和数值传热学等学科,当前国内外学者未考 虑变压器整体油流分布对绕组温升的影响。基于电磁-热-流弱耦合分析法,通过对变压器整体油 路三维有限体积分析和绕组杂散损耗有限元数值分析,确定绕组温升数值分析的边界条件,计算绕 组区域的温度场,研究绕组区域的铜—油温升和油流分布,考虑分析了不均匀油流分布下绕组区域 的散热情况。以提高测温点数量与减小光纤对油路影响为前提,设计进行了高压绕组光纤测温实 验,对比实验值与数值分析值,所得误差均在±3. 5%以内,证明了耦合方法可直接应用于电力变压 器绕组冷却系统的设计与优化。
Abstract:
Research on winding heat problems involves disciplines such as electromagnetics, fluid dynamics and numerical heat transfer. Based on electromagneticfluidthermal coupling analysis method,the boundary conditions of numerical analysis of winding temperature rise was established,the temperature field of the winding area was calculated,the copper-oil temperature rise and oil flow distribution in the winding were researched,the heat dissipation of the winding area with uneven oil flow distribution was analyzed. The experimental of fiber optic temperature measurement was designed for high voltage winding on the condition of increasing the number of temperature measurement points and reducing the impact of the fiber on the oil circuit. Comparing the experimental and numerical analysis values, the error is within ±3. 5%. It proves the coupled method can be directly applied to the design and optimization of power transformer winding cooling system.
